The Benefits of Xylitol and Fluoride


Have you ever wondered why dentists encourage the use of fluoride toothpaste, or why gum companies advertise the use of xylitol in their products? At Moscattini Dental, we have created this guide to explain the benefits of items containing xylitol and fluoride, why they should be used, and for whom.

What is Xylitol?


As a sugar-alcohol, xylitol occurs naturally in many plants and is processed to become a sweetener used in a variety of food products, including chewing gum.

How Xylitol Benefits Oral Health


Xylitol contains fewer calories than regular sugar. Studies have shown that microbes in your mouth are unable to metabolize xylitol in the same way as sugar, starving the bacteria that regularly cause decay through acid production. It has also been found to re-mineralize previously demineralized portions of the enamel, strengthening your teeth against decay. These effects make xylitol gum naturally appealing as a sugar substitute that also prevents cavities.

We recommend the use of xylitol gum for adults and children to preserve the strength of dental enamel, and reduce the habit of chewing decay-causing sugary gum.

What is Fluoride?


Fluoride is found as an additive in city water supplies and oral care products, including toothpastes. While naturally occurring in many environments such as water sources with certain geological conditions, this compound encourages stronger teeth and protects against decay. 

Why is Fluoride Recommended?


Much like xylitol, fluoride is able to spur remineralization, fighting cavities that break down enamel. For patients who are over the age of two, the use of fluoride enriched toothpaste is encouraged to ensure that their teeth remain healthy in the long term. If your drinking water is not fluoridated, consult your dentist to see if you would benefit from the use of additional gels, mouthwashes, or other fluoride enriched products.

Too much exposure to fluoride can have a negative effect during the formative stage of the enamel. This overexposure is referred to as dental fluorosis, and can result in bright spots on the teeth and staining. To avoid dental fluorosis, use fluoride-free toothpaste before your child is able to brush their teeth without swallowing the toothpaste, and consult your dentist to determine ideal fluoride use for your family.


If you would like to learn more about the benefits of xylitol and fluoride, contact Dr. Moscattini and our dental team today. Moscattini Dental provides patients throughout Duluth, Johns Creek, Suwanee, Norcross, and the neighboring communities with quality care and education necessary to maintain healthy smiles.

Applying dental sealants to the back teeth could prevent up to 80% of cavities in school-aged children, yet about 57% of children between the ages of 6 and 11 years don’t get sealants, according to the US Centers for Disease Control and Prevention (CDC). Yet increasing access to school-based sealant programs (SBSPs) could remedy these low figures, especially among low-income families who are less likely to have access to dental care, the federal agency notes.

SBSPs target schools with a high percentage of students who are eligible for free or reduced-cost meal programs. As a result, they provide sealants to children who are at higher risk for cavities and less likely to receive preventive care. Prior research has found that children with poor oral health often struggle academically and even miss significant time in school due to pain and other issues.
“Many children with untreated cavities will have difficulty eating, speaking, and learning,” said CDC director Tom Frieden, MD, MPH. “Dental sealants can be an effective and inexpensive way to prevent cavities, yet only one in 3 low-income children currently receive them. School-based sealant programs are an effective way to get sealants to children.”

In addition to preventing 80% of cavities for 2 years after application, dental sealants continue to protect against 50% of cavities for up to 4 years after placement. They can be retained in the mouth for as long as 9 years. Also, while about 43% of 6- to 11-year-olds have a sealant, low-income children are 20% less likely to have them than higher-income children. Plus, school-age children without sealants have almost 3 times more cavities than those with sealants.

The CDC further reports that applying sealants to the nearly 7 million low-income children who don’t have them could save up to $300 million in dental treatment costs. The agency currently provides funding to 21 state public health departments to coordinate and implement school-based and school-linked sealant programs that target low-income children and those who live in rural settings. The CDC also says that state officials can:


  • Target SBSPs to the areas of greatest need in their state
  • Track the number of schools and children participating in SBSPs
  • Implement policies that deliver SBSPs in the most cost-effective manner
  • Help connect schools with health departments, Medicaid, and Children’s Health Insurance Program offices, community health centers, and dental professionals in the community

Mouthguards do more than protect an athlete’s teeth during the heat of competition. They also may improve performance and guard against other injuries, according to the AGD. For example, clenching a mouthguard while heading a soccer ball activates the neck and jaw muscles and may protect against concussion. It also repositions the jaw to activate the head and neck muscles, which may help weightlifters feel stronger and less encumbered. And, it modifies the airway opening to make breathing more efficient during physical activity.

 Not all athletes take advantage of these benefits, though. The AGD reports that 56% of the 503 middle- and high-school athletes surveyed in Houston in a recent study did not own a mouthguard. Most commonly, the students said they didn’t wear one because they forgot to or because the mouthguard wasn’t comfortable. The AGD urges members of the dental profession to encourage enforcement of mouthguard usage policies among student-athletes.

 The study, “Mouthguard Usage by Middle and High School Student-Athletes in Houston, Texas,” was published by General Dentistry.

Patients with head and neck squamous cell carcinoma (HNSCC) who practice better dental care and consume less alcohol and tobacco have better survival times than those who don’t, according to a study funded by the German Research Foundation.

 The study recruited 276 HNSCC cases and followed them for 6 to 10 years. Interviews included information about dentures, gum bleeding, brushing, flossing, and dental visits, in addition to mouthwash use, smoking, drinking, and diet. The researchers defined good dental care by annual dental visits, daily teeth cleaning, and flossing.
The difference in median survival time between patients with good dental care and poor dental care was 81 months. According to the researchers, the results imply a lack of dental care might contribute to the risk of earlier death or tumor progression, but the effect was not statistically significant.

 Patients who smoked 20 cigarettes a day saw their risk of tumor recurrence or death increase by a factor of 3. Patients who had at 2 alcoholic drinks a day saw their risk of tumor progression increase by a factor of 1.5. The researchers also found that using alcoholic or non-alcoholic mouthwash at least twice a day doubled the risk of tumor-specific death, though reasons why remain unclear.

 While these elevated hazard ratios indicate good dental care may have a positive impact on survival rates, the researchers noted, the study’s value is limited by its small sample size. The study, “Pretreatment Oral Hygiene Habits and Survival of Head and Neck Squamous Cell Carcinoma (HNSCC) Patients,” was published by BMC Oral Health.

Shirley Anderson had to have his Adam’s apple and mandible both removed after his tongue cancer returned, leaving the 68-year-old man from Evansville, Ind, without a chin. But traditional prosthetic materials were bulky and cumbersome.

 “This was a unique case,” said Dr. Travis Bellicchi, a second-year maxillofacial prosthodontics resident at the Indiana University School of Dentistry at Indiana University-Perdue University Indianapolis. “It’s a much larger prosthesis that what we normally work on. Typically we might do a nose or an ear. This is maybe 4 or 5 times larger.”

 Bellicchi, an Indiana University School of Medicine Maxillofacial Prosthetics Fellow, typically serves as a bridge between restorative dental and medical specialties for patients who have had cancer surgery or who have experienced facial trauma from car accidents, gunshot wounds, or burns.

 “My training allows me to provide prostheses when surgical intervention or reconstructions are insufficient to provide a good aesthetic or a functional result,” Bellicchi said. “Then I come in and make something out of silicone or acrylic resin that would restore function or, in this case, aesthetics.”

 Bellicchi relies on medical, information technology, design, and engineering experts from across Indiana University and Purdue University. His interdisciplinary team is creating a hybrid digital and analog approach, using 3-D printing to create molds with negative space inside of them. The negative space becomes the prosthesis itself.

 “Then I use traditional materials, for now, to fill that space,” Bellicchi said. “My motivation to use traditional materials is that they are predictable, they are biocompatible, they have research behind them, and we know how to do the characterization to make them lifelike.”

 Anderson was first diagnosed with tongue cancer in 1997 and treated with radiation. The disease returned in 2012. After new radiation treatment, he developed osteoradionecrosis of the jaw. Head and neck surgeons attempted to reconstruct his mandible using pieces of bone from his fibula and a titanium bar, but were unsuccessful.

 So, Bellicchi turned to a digital solution. He and his team have completed digital imaging and modeling of Anderson’s face, and they soon expect to use 3-D printing to produce a prototype of a 3-D printed prosthesis itself. Anderson, who currently breathes through a tracheotomy and is fed through a tube in his stomach, hopes some semblance of normal will return with a better looking and fitting prosthetic.

 “Shirley really believes in helping us as an institution,” Bellicchi said. “He totally gets the work we are trying to do on the discovery side of this as well as the patient-care side. He is a problem solver and a funny guy. I couldn’t have asked for a better person to spend a year with as I come up with different prosthesis solutions and explore the digital protocol.”

Researchers at the National Cerebral and Cardiovascular Center in Osaka, Japan, have discovered a potential link between oral health and the risk of stroke. According to their data, 26% of their patients who had experienced intracerebral hemorrhage had cnm-positive Streptococcus mutans in their saliva. Meanwhile, only 6% of patients who suffered from other types of stroke tested positive for the bacterium.

 Also, MRIs revealed significantly higher numbers of cerebral microbleeds in subjects with cnm-positive S. mutans than in those without the bacterium. Cerebral microbleeds are small brain hemorrhages that may cause dementia and often underlie intracerebral hemorrhages. The researchers believe S. mutans may bind to blood vessels weakened by age and high blood pressure, causing arterial ruptures in the brain and leading to small or large hemorrhages.

 “This study shows that oral health is important for brain health. People need to take care of their teeth because it is good for their brain and their heart as well as their teeth,” said Robert P. Friedland, MD, co-author of the study and the Mason C. and Mary D. Rudd endowed chair and professor of neurology at the University of Louisville School of Medicine.

 “The study and related work in our labs have shown that oral bacterial are involved in several kinds of stroke, including brain hemorrhages and strokes that lead to dementia,” Friedland said. He also noted that the cnm-negative strain of S. mutans causes tooth decay and is found in approximately 10% of the population. Currently, he is researching how oral bacteria may influence other diseases affecting the brain.

 “We are investigating the role of oral and gut bacteria in the initiation of pathology in the neurodegenerative disorders Alzheimer’s and Parkinson’s with collaborators in the United Kingdom and Japan,” he said.

 The study, “Intracerebral Hemorrhage and Deep Microbleeds Associated with cnm-positive Streptococcus Mutans; a Hospital Cohort Study,” was published by Scientific Reports.

Sharks are infamous for their ability to regrow teeth throughout their lifetime, while human beings only get a couple of sets. Researchers at the University of Sheffield in the United Kingdom, though, have identified the genes that give sharks their regenerative capacity, with an eye on someday giving people the same ability.

 “We know that sharks are fearsome predators, and one of the main reasons they are so successful at hunting prey is because of their rows of backward-pointing, razor-sharp teeth that regenerate rapidly throughout their lifetime and so are replaced before decay,” said Dr. Gareth Fraser of the University of Sheffield.

 The researchers have identified how a special set of epithelial cells, known as dental lamina, forms in sharks. These cells are responsible for lifelong tooth development and regeneration in sharks, conserved throughout 450 million years of evolution. Human beings have these cells too, but they only form baby and adult teeth before they are lost.

 “The Jaws films taught us that it’s not always safe to go into the water, but this study shows that perhaps we need to in order to develop therapies that might help humans with tooth loss,” said Fraser.

 By analyzing the teeth of catshark embryos, the researchers characterized the expression of genes during stages of early shark tooth formation. They found that these genes participate in the initial emergence of the teeth and are redeployed for further tooth regeneration.

 At the beginning of the sharks’ evolutionary history, the researchers said, their teeth most likely were continuously regenerated and used a core set of genes from members of key developmental signaling pathways that were instrumental in evolving to redeploying the genes to replace teeth when needed.

 Shark dentition is formed and patterned via these highly conserved signals, which are used by all toothed vertebrates, the researchers said. Slight genetic alterations, they added, could be the difference between the limited replacement supply of teeth that mammals have and the unlimited dentition that sharks have.

 The study, “An Ancient Dental Gene Set Governs Development and Continuous Regeneration of Teeth in Sharks,” was published by Science Direct. It was supported by the Natural Environment Research Council and the Leverhulme Trust.

Tooth decay may be even worse than originally thought.
A new study suggests that tooth decay may push back growth in children. The study appeared in the online version of Pediatrics journal and was conducted at University College London and King Fahad Armed Forces Hospital in Saudi Arabia.
The research team wanted to explore the relationship between oral health and growth after previous studies failed to show definitive evidence one way or the other. In this study, the researchers looked at the dental decay and the correlation between height and weight in Saudi Arabian children ages 6 through 8.
The oral health of the children was graded on the DMFT scale, which is a scale that determines the seriousness of decayed, missing and filled teeth.
The research team later analyzed the statistics and concluded that there was, in fact, a relationship between low height/weight and a greater number of cavities. Children with severe decay had a higher chance of being underweight and shorter when compared to their peers.
Even when some secondary factors, like demographics and social values, were factored in, the correlation between decay and stunted growth still existed. Based on this study, it’s fair to say there is an inverse relationship between growth and tooth decay in children. More research is necessary to confirm this study’s findings.

Have you seen news stories declaring the cavity fighting powers of red wine? Think it seems too good to be true? 

You’re right to be skeptical. Despite recent stories, it turns out that drinking red wine hasn’t been shown to be good for your teeth. The stories were based on a study in the Journal of Agricultural and Food Chemistry which found that red wine with or without alcohol had no effect on the growth of S. mutans, the bacteria that causes cavities. What the researchers actually reported was that red wine and dealcoholized red wine were effective in limiting growth of F. nucleatum and S. oralis—two bacteria that are closely associated with gum disease. 

So, does this mean red wine may be good for gum health? Maybe. If you hold it in your mouth for two minutes every seven hours for seven days like the researchers did. For now, the ADA recommends you stick to brushing for two minutes twice a day and flossing daily for good dental health.

In this spotlight feature, to coincide with National Dental Hygiene Month, we peer beneath the plaque to investigate what other - perhaps unexpected - health conditions are affected by poor dental health.

Alzheimer's disease
In 2010, researchers from New York University (NYU) concluded that there is a link between gum inflammation and Alzheimer's disease, after reviewing 20 years of data on the association.

However, the number of participants in the NYU study was fairly small. The researchers analyzed data from 152 subjects enrolled in the Glostrop Aging Study - a study looking at psychological, medical and oral health in Danish men and women. The study spanned a 20-year period and ended in 1984, when the subjects were all over the age of 70.

Comparing cognitive function at ages 50 and 70, the NYU team found that gum disease at the age of 70 was strongly associated with low scores for cognitive function.

Study participants were nine times more likely to have a score in the lower range of the cognitive test - the "digit symbol test" (DST) - if they had inflammation of the gums.

Although this study took into account potentially confounding factors like obesity, cigarette smoking and tooth loss unrelated to gum inflammation, there was still a strong association between low DST score and gum inflammation.

In 2013, UK-based researchers from the University of Central Lancashire (UCLan) built on the findings of this study, by comparing brain samples from 10 living patients with Alzheimer's with 10 brain samples from people who did not have the disease.

Analysis showed that a bacterium - Porphyromonas gingivalis - was present in the Alzheimer's brain samples but not in the samples from the brains of people who did not have Alzheimer's. What was interesting was that P. gingivalis is usually associated with chronic gum disease.

The team followed up this research in 2014 with a new mouse study, the results of which were published in the Journal of Alzheimer's Disease. Medical News Today spoke to co-author Dr. Sim K. Singhrao regarding the findings.

Dr. Singhrao says that there is sufficient scientific evidence to show that two of the three gum disease-causing bacteria are capable of motion (or "motile") and have been consistently found in brain tissue.

"These motile bacteria can leave the mouth and enter the brain via two main routes," he explains. "They can use their movement capability to directly enter the brain. One of the paths taken is to crawl up the nerves that connect the brain and the roots of teeth. The other path is indirect entry into the brain via the blood circulation system."

In a patient who has bleeding gums, says Dr. Singharo, the gum disease-causing bacteria will enter the blood stream every time they clean their mouth and even when they eat food.

He continues:

"P. gingivalis is particularly interesting as it has found ways to hitch a lift from red blood cells when in the blood stream and instead of getting 'off the red blood cell bus' in the spleen, they choose to get off in the brain at an area where there are no immune checkpoints. From there, they spread to the brain at their will. In addition, in older individuals, the blood vessels tend to enlarge and become leaky."

"The published work confirmed P. gingivalis placed in the mouths of mice finds its way to the brain once gum disease becomes established first," Dr. Singhrao concludes. "Furthermore, our hypothesis is strengthened by the recent results demonstrating that the chemicals released by the brain's immune system in response to P. gingivalis reaching the brain 'inadvertently' damage functional neurons in the area of the brain related to memory."

Pancreatic cancer
A research team from Harvard School of Public Health in Boston, MA, were the first to report strong evidence on a link between gum disease and pancreatic cancer, back in 2007.

The type of gum inflammation associated with pancreatic cancer in the study was periodontitis, which affects the tissue that support the teeth and can cause loss of bone around the base of the teeth.

The other main kind of gum disease - gingivitis; where the tissue around the teeth becomes inflamed - was not linked to increased cancer risk. However, gingivitis can lead to periodontitis if persistent. Gingivitis happens when bacteria in the plaque around the base of the teeth build up due to bad dental hygiene.

Examining data on gum disease from the Health Professionals Follow-Up Study, which involved a cohort of more than 51,000 men and began collecting data in 1986, the Harvard researchers found that men with a history of gum disease had a 64% increased risk of pancreatic cancer compared with men who had never had gum disease.

The greatest risk for pancreatic cancer among this group was in men with recent tooth loss. However, the study was unable to find links between other types of oral health problems - such as tooth decay - and pancreatic cancer.

The researchers suggest that there may be a link between high levels of carcinogenic compounds found in the mouths of people with gum disease and pancreatic cancer risk. They argue that these compounds - called nitrosamines - may react to the digestive chemicals in the gut in a way that creates an environment favorable to the development of pancreatic cancer.

However, a follow-up study from the team in 2012 was unable to prove whether the periodontitis bacteria are a cause or result of pancreatic cancer - the study could only prove that the two were linked.

"This is not an established risk factor," admitted author Dominique Michaud. "But I feel more confident that something is going on. It's something we need to understand better."

Heart disease
Perhaps more well established is the association between dental hygiene and heart disease.

In 2008, MNT reported on research from joint teams at the University of Bristol in the UK and the Royal College of Surgeons in Dublin, Ireland, who found that people with bleeding gums from poor dental hygiene could be increasing their risk of heart disease.

The researchers found that heart disease risk increased because - in people who have bleeding gums - bacteria from the mouth is able to enter the bloodstream and stick to platelets, which can then form blood clots, interrupting the flow of blood to the heart and triggering a heart attack.

"The mouth is probably the dirtiest place in the human body," said Dr. Steve Kerrigan from the Royal College of Surgeons, explaining that there are up to 700 different types of bacteria co-existing in our mouths.

Prof. Howard Jenkinson, from the University of Bristol, added:

"Cardiovascular disease is currently the biggest killer in the western world. Oral bacteria such as Streptococcus gordonii and Streptococcus sanguinis are common infecting agents, and we now recognise that bacterial infections are an independent risk factor for heart diseases."

The Bristol University researchers investigated how the bacteria interact with platelets by mimicking the pressure inside the blood vessels and the heart. Prof. Jenkinson's team found that the bacteria use the platelets as a defense mechanism.

By clumping the platelets together, the bacteria are able to completely surround themselves. This platelet armor shields the bacteria from attack by immune cells and makes them less detectable to antibiotics.

Although some of the associations we have looked at in this spotlight feature are still under investigation, good dental hygiene remains important for lowering risk of a variety of conditions.

The American Dental Hygienists' Association (ADHA) recommend that we should brush for 2 minutes, twice daily. The ADHA guidelines also stress the importance of flossing daily and rinsing with mouthwash. You can read the full recommendations on the ADHA website.

It may be beneficial for children to be given fluoride even earlier than they receive it now, according to the American Dental Association.
Previous information suggested children receive fluoride by the time they were 6. This new information, however, suggests that children be administered fluoride even earlier. The new ADA recommendation states that children should be given fluoride as soon as their first teeth develop.
When children use fluoride toothpaste at an early age, it can lower the rate of decay. Research suggests that around one quarter of children develop a cavity before reaching kindergarten but more children using fluoride at an earlier age can lower that number.
The change in position on when a child should start using fluoride comes after a study from the Journal of the American Dental Association.
The study also indicated that pea-sized quantities of toothpaste can lead to a higher risk of fluorosis when toothpaste is ingested. Children younger than 3 should use smaller amounts of toothpaste. The ADA recommends parents watch their children clean their teeth to make certain the children spit out the toothpaste as opposed to swallowing it.
More studies on fluoride will be conducted to determine when is the exact time children should initially use it. There are many different opinions regarding how people feel about fluoride and this information won’t change those beliefs.

Archaeologists and geneticists have been puzzling this question since it was revealed that the mutations which enable adults to drink milk are under the strongest selection of any in the human genome.
These mutations cause the intestinal enzyme lactase -- which digests lactose milk sugar during infancy -- to continue to be produced long after weaning. This lactase persistence is prevalent only in some populations around the world such as in Northern Europe. In most other people of the world, the lactose cannot be properly digested and can cause diarrhea, or other symptoms of lactose intolerance resulting from the gases produced by fermentation by the gut bacteria.
Some dairy products such as yoghurt and cheese have had their lactose content reduced or removed through processing. In the case of cheese, the lactose ends up in the whey, where it is often fed to pigs and other animals. If it is so easy to remove milk sugars, and the mutation is only required for drinking raw milk or whey -- why is it under such strong selection?
An international team of researchers involving the Universities of York, Oklahoma and Copenhagen, and University College London (UCL) has shed new light on this puzzling question through an unusual source -- investigations of calcified dental plaque on ancient human teeth.
To understand how, where and when humans consumed milk products, it is necessary to link evidence of consumption directly to individuals and their livestock. Previous research by archaeologists has used indirect lines of evidence, such a high frequency of adult females in animal herds or milk lipids present on pots, to identify evidence of dairying.
Now a breakthrough by the international team, reported in the journalScientific Reports, provides the first direct evidence of milk drinking from an increasingly important archaeological reservoir -- human dental calculus, a mineralized form of dental plaque. Using the latest mass spectrometry-based techniques for ancient protein sequencing, the team detected a milk protein, beta-lactoglobulin (which they had previously reported from a modern dental plaque sample) in ancient remains.
Lead author Jessica Hendy, from the University of York's BioArCh research facility, said: "It seemed too good to be true; beta-lactoglobulin is the dominant whey protein -- the one used by bodybuilders to build muscle mass -- and therefore the ideal marker for milk consumption. We kept finding sequences of beta-lactoglobulin and at first we thought it could be modern contamination. But we repeated the analysis several times, at three different laboratories in three different countries, each time finding the same results."
Lead author Dr Christina Warinner, from the Department of Anthropology, University of Oklahoma, said: "The study has far-reaching implications for understanding the relationship between human diet and evolution. Dairy products are a very recent, post-Neolithic dietary innovation, and most of the world's population is unable to digest lactose, often developing the symptoms of lactose intolerance."
Professor Dallas Swallow, from the Research Department of Genetics, Evolution and Environment at UCL, added: "It is only within the last several thousand years that genetic mutations arose in Europe, East Africa, and the Arabian Peninsula that allowed lactase to persist into adulthood, a genetic trait that enables lifelong milk consumption."
The new research provides direct protein evidence that cattle, sheep, and goat whey has been consumed by human populations for at least 5,000 years. This corroborates previous isotopic evidence for milk fats identified on pottery and cooking utensils in early farming communities. Until now it has been difficult to investigate both human genetic milk adaptations and direct evidence of milk consumption at the same time, in part because milk preserves so poorly in the archaeological record.
"The discovery of milk proteins in human dental calculus will allow scientists to unite these lines of evidence and compare the genetic traits and cultural behaviors of specific individuals who lived thousands of years ago," says Dr Warinner.The team found direct evidence of milk consumption preserved in human dental plaque from the Bronze Age to the present day.
Professor Matthew Collins, of BioArCh in York's Department of Archaeology, said: "Some of the findings were as we expected. For example, we did not find any evidence of milk protein in 19th century West African individuals from regions where dairying was uncommon. But we found widespread evidence for milk consumption at European sites spanning a period of 5,000 years."
Dr Camilla Speller, from York's BioArCh research facility, said: "Most of the molecular evidence for milk consumption has previously come from residues on ceramics. While pot residues can tell you that people are using dairy products, it can't tell you which individuals in the group are actually consuming the milk. This study is very exciting, because for the first time, we can link milk consumption to specific skeletons, and figure out who has access to this important nutritional resource."
Dr Enrico Cappellini, from the Centre for GeoGenetics, Natural History Museum of Denmark, University of Copenhagen, says the milk protein beta-lactoglobulin is also an important find because it contains sequence variants that allow different milk-producing livestock to be distinguished.
"We found widespread evidence of cows' and sheep milk consumption as early as the Bronze Age, whereas evidence for goat milk consumption was limited to Bronze Age northern Italy," he said.

A recent study by researchers at the University of Melbourne's Oral Health Cooperative Research Centre suggests that sugar free products can cause measurable damage to the tooth enamel, NDTV reports.
"Many people are not aware that while reducing your sugar intake does reduce your risk of dental decay, the chemical mix of acids in some foods and drinks can cause the equally damaging condition of dental erosion," said Eric Reynolds, CEO of the Oral Health CRC.
"Dental erosion occurs when acid dissolves the hard tissues of the tooth. In its early stages erosion strips away the surface layers of tooth enamel. If it progresses to an advanced stage it can expose the soft pulp inside the tooth," said Reynolds.
For the study, the researchers tested 23 different types of drink. They found that drinks that contain acidic additives and with low pH levels cause significant damage to dental enamel, even if the drink is sugar-free.
The researchers also measured dental enamel softening and tooth surface loss due to the consuming the range of drinks. They found that majority of soft drinks and sports drinks caused softening of dental enamel by 30-50 per cent.
The study concluded that both sugar-containing and sugar-free soft drinks produced measurable loss of the tooth surface, with no significant difference between the two groups of drinks.
Reynolds also pointed out that 'sugar-free' labelling does not mean a product is safe for teeth.
"We have even found sugar-free confectionery products that are labelled 'tooth-friendly' and which when tested were found to be erosive," said Reynolds.

If you’ve ever heard someone talk about getting a root canal, you get the feeling that this endodontic procedure is a nightmare. However, a root canal is a tooth-saving dental treatment that can dramatically improve your oral health if you have severely damaged teeth, or even a tooth infection. Don’t let anxiety over a dental treatment prevent you from getting the care you need. We bust some popular myths about root canals below:
  • Root Canals are Complicated Oral Surgery – A root canal is a dental procedure that requires the use of special instruments, controlled by skilled dentist or endodontist, but it is not a complicated surgical procedure, like some might think. In order to treat a damaged tooth with a root canal, Dr. Moscattini will remove infected tooth pulp (the material inside the tooth) by creating a small opening in the dental crown. This process is not much more invasive than getting a filling, crown, or other treatment that requires modification of dental enamel.


  • Root Canals are Extraordinarily Painful – This is likely the biggest lie told about root canal treatment. While some may think that root canals are complex and uncomfortable, many patients report that it feels no different than receiving a filling. Dr. Moscattini will apply a local anesthetic before beginning treatment, so you remain comfortable and relaxed.


  • Root Canals Damage your Teeth – Quite the opposite, a root canal is specifically intended to save teeth and does not “kill” a live tooth. Before root canal treatment was honed, the standard course of action for an infected or damaged tooth was extraction. But extracting teeth creates a host of other oral health problems that root canals can prevent. By removing affected material from inside your tooth, Dr. Moscattini can save your tooth’s structure and further protect your oral health by capping off your treatment with a dental crown.


  • If You Get Another Tooth Infection, It’s Better Have the Tooth Extracted – Extraction is always a worst-case scenario. Dr. Moscattini takes every tooth-saving measure possible to ensure that you get to keep your natural teeth as long as possible. If you’ve previously had a root canal and experience another infection at the same site, your tooth can be successfully re-treated with root canal therapy.

Keeping healthy teeth and gums at every age is an important part of overall well-being . Kid’s oral health needs often require special attention from both little ones themselves and their caregivers. Here are some important things to keep in mind when considering your children’s oral health needs:


1.) Kid’s Teeth are More Porous – Baby teeth are home to pores and pits that aren’t found on adult teeth. This means that kid’s teeth require special protection to prevent debris and bacteria from settling in these spaces and causing damage. As a family dentist, Dr. Moscattini can apply sealants and fluoride varnishes for young smiles, to help them stay strong and seal out agents of decay.

2.) Keeping Baby Teeth Healthy is Important – Many parents believe that baby teeth don’t need special care, as they’ll eventually fall out. However, keeping up good oral health for these teeth is crucial to ensuring a lifetime of healthy teeth and gums. If a child’s baby teeth begin to decay, they are at a higher risk for developing more complicated oral health problems in the future.

3.) Kids Need to Keep up Routine Dental Checkups, Just like Adults – Children don’t get to put off going to the dentist just because their permanent teeth aren’t in yet. Dental cleanings, for any patient, allow Dr. Moscattini to spot potential problems ahead of time and to thoroughly clean teeth to remove buildup of plaque. Because children are still learning how to take good care of their teeth, keeping regular dental appointments for x-rays and teeth cleanings is vital.


4.) Children Sometimes Need Help – As kids learn what it means to successfully clean their teeth each day, they’ll need guidance to make sure they’re doing it right. Young children may need help from caregivers to floss and reach all of their teeth with a toothbrush to keep them healthy.


5.) Your Children’s Oral Health Habits Will Be Modeled after Your Own – Children’s parents or caregivers are their role models for many behaviors, including hygiene care. If you brush and floss your teeth regularly, children will take a cue from you and follow the same habits. It’s important to keep up with your own oral health needs, in order to set the right example for kids.


With the right care, it’s possible for every member of your family to have beautiful, healthy smiles. For more information on family-friendly dentistry, contact the Duluth family dental office of Roy Moscattini, DDS.

If you’re looking to get a more attractive smile, cosmetic dental treatments can get you there by addressing teeth staining, misalignment, missing teeth, or signs of decay. However, if you’re worried that your cosmetic dental treatment plan will involve repeated trips back to a dental office, Dr. Moscattini is happy to offer many cosmetic procedures that can be completed in one office visit.


  • Teeth Whitening – If your teeth are severely stained, you can get a fresh new smile the same day with professional teeth whitening services at Dr Moscattini’s Duluth dental office. Dr. Moscattini uses the trusted Zoom!® whitening brand to help lift stains off of teeth. The best part is, Zoom!® whitening treatment typically only takes an hour. Zoom!® is safe, comfortable and effective!
  • Composite Fillings – Cavities are, unfortunately, a common oral health concern that used to be addressed with metal amalgam fillings. However, metal is dark and stands out in contrast to your natural dental enamel. Dr. Moscattini uses tooth-colored filling material to treat cavities at his Duluth cosmetic dental office. No one but you and your dentist will know that you have had cavity treatment -- your smile will remain naturally beautiful.
  • Root Canal Therapy - Decayed teeth are a serious oral health problem and can stand out as darkened or yellowed in the rest of your smile. Root canal therapy is an endodontic procedure that corrects issues of tooth infection and decay by removing affected material from inside your tooth, saving your natural tooth from needing extraction and restoring it to its natural appearance. A root canal can typically be completed in a few hours and can later be topped with a dental crown for furthered support and improved aesthetic.
  • Bonding – Cosmetic dental bonding makes your teeth appear more even and symmetrical in the face of uneven wear and tear on teeth. Dr. Moscattini will apply and shape a tooth-colored resin to enhance your smile’s appearance. Dental bonding is affordable, convenient, will last for years, and only takes a short time to complete.


You don’t have to wait forever to get a more appealing smile. Dr. Moscattini’s dental office offers same-day cosmetic dental procedures in Duluth that improve your appearance, as well as your oral health.  For patients requiring additional or extended treatment plans, Dr. Moscattini also offers Invisalign®, dental implants, veneers, and fixed bridges. To get more information on one-appointment dental visits, contact Dr. Moscattini’s Duluth dental office today!
