Is it Possible to Regrow Teeth Enamel?

by

According to the National Institutes of Health the most prevalent form of chronic disease is tooth decay. Janet Moradian-Oldak at USC has  investigated methods to regrow tooth enamel which is a difficult undertaking as tooth enamel is not a living tissue. She collaborated with Sauma Prajapati and others to investigate matrix metalloproteinase-20, an enzyme found only in teeth which facilitate organized enamel crystal formation. Her team is the first to define the function of an enzyme for preventing protein occlusion inside a crystal. MMP-20 is released at a very early stage of enamel formation. MMP-20 chops up proteins during the crystallization of enamel. Together with other enzymes, it gets rid of ‘sludge’ so the enamel making cells in the body can add more mineral and make enamel, the hardest bioceramic in the human body. The team also looked an amelogenin-chitosan hydrogel which could repair early tooth decay … Read more

High Acid Drinks Can Damage Teeth

by

So I have previously written about how sports and energy drinks can cause permanent tooth damage. See the post https://blog.teethremoval.com/sports-and-energy-drinks-can-cause-permanent-tooth-damage/ where it is mentioned that the high acidity levels in the drinks erode tooth enamel. Similar sentiments are echoed in a more recent article titled “Three-dimensional profilometric assessment of early enamel erosion simulating gastric regurgitation,” appearing in the Journal of Dentistry in 2014 written by Chelsea Mann and et al. The researchers in this more recent article present results to show that lifelong damage is caused by acidity to teeth within the first 30 seconds of an acid attack. The researchers state that dental erosion is often detected clinically after extensive tooth wear has already occurred. Furthermore, the researchers state that drinks high in acidity like sports drinks, soft drinks, and fruit juice when combined with night time tooth grinding can cause … Read more

Using Teeth to Determine Where you are From

by

An interesting article titled “The Pb isotopic record of historical to modern human lead exposure,” appears in the journal Science of The Total Environment written by George D. Kamenov and Brian L. Gulson (vol. 490, pp. 861-870, 2014). George Kamenov is a University of Florida geology professor. The article describes how trace amounts of lead present in teeth can give clues about what geographical region the teeth (and the person) came from. What is interesting about this article, is that the lead in the teeth can be used to pinpoint the geographic area where the teeth originated from. This is because lead is composed of four different isotopes which fluctuate in different rocks and soils around the world. As children grow they inhale dust and ingest soil which contains the different isotopes of lead. As tooth enamel forms during childhood, it … Read more

Cheese may aid in cavity prevention

by

In an article appearing in the May/June 2013 issue of General Dentistry, it was found that eating cheese and other diary products may be beneficial in protecting teeth against cavities. The study sampled 68 subjects between the ages of 12 and 15 and looked at their dental plaque pH in their mouth before and after eating cheese, yogurt, and milk. In fact, three different groups were used one that eat cheddar cheese another that drink milk and another that eat sugar free yogurt. Each group was told to eat/drink for around 3 minutes and then swish their mouth with water. Then the researchers measured the pH level of each subject’s mouth at 10, 20 and 30 minutes after they finished eating/drinking. The researchers found that the groups who drank milk and ate yogurt had no changes in pH levels in … Read more

Sports and Energy Drinks Can Cause Permanent Tooth Damage

by

I have previously written about how sports and energy drinks can cause tooth erosion see https://blog.teethremoval.com/energy-drinks-cause-tooth-erosion/. Studies have shown that 30% to 50% of U.S. teens are consuming energy drinks, and up to 62% are consuming at least one sports drink per day. A study published in the May/June 2012 issue of General Dentistry, the journal of the Academy of General Dentistry, found that an alarming increase in the consumption of sports and energy drinks, especially among adolescents, is causing irreversible damage to teeth — specifically, the high acidity levels in the drinks erode tooth enamel, the glossy outer layer of the tooth. Poonam Jain, BDS, MS, MPH, lead author of the study says “Young adults consume these drinks assuming that they will improve their sports performance and energy levels and that they are ‘better’ for them than soda. Most … Read more
