The Gene FAM20A, A New Key For Our Dental Health

It is a known fact that people can not restore their tooth enamel, and if it is damaged as a result of an improper dental care, poor diet or other factors, we have nothing else to do but visit our dentist and place a type of tooth filling. This is explained by the phenomenon that the cells that produce our tooth enamel (which are called ameloblasts) are meant to retire after the necessary amount of enamel to cover up out mature teeth is produced. Nowadays, the scientists found out what gene is responsible for tooth enamel formation and quality.

A group of specialists at the University of Manchester, leaded by Dr. James O’Sullivan analyzed the genomes of the members of the same family. At that, four of the relatives shared the a certain genetic disorder known as amelogenesis imperfecta, which is associated with too weak and thin tooth enamel, and the rest five members of the same family were not diagnosed with the mentioned disease. tooth enamelFurther, genetic samples were compared to more than nine hundred other genetic samples taken from other people who did not have the signs of the mentioned disorder.

It turned out that the family members affected by the disorder had mutations in both copies of FAM20A gene, and those relatives who did not have the disorder had only one copy of the gene affected by mutations. No other genetic sample taken from other people had the stated type of mutation. The researchers also noticed that in mice, extremely high rates of normal FAM20A gene could be found during the maturing period of ameloblasts, supporting the theory that FAM20A has a great importance for healthy tooth enamel formation.

Other specialists are trying to find some explanation of the discovered phenomenon. An expert at the University of Western Australia in Crawley, Tony Phan, supposes that the gene produces a type of protein which can stimulate the production of tooth enamel cells by in some way binding to ameloblasts. If this theory will find scientific evidence, there can be a way opened to using this protein for reactivation of ameloblasts and making them produce new tooth enamel sells when the tooth is decaying or is damaged. Read more about this interesting study and its findings in the latest issue of the American Journal of Human Genetics.

5 Worst Enemies Of Your Shiny Smile

We all know so well that using our teeth for opening nut shells or eating too much of sweet foods (especially chocolate or soft candies) may have serious destructive effects on our tooth enamel. In addition, there are many foods and drinks which can change color or damage our tooth enamel (both physically and qualitatively), cause plaque and serious dental diseases. Below, you can see a list of 5 most dangerous foods and drinks which should be considered 5 worst enemies of our shiny smile.

1.shiny smile Carbonated drinks. First of all, soft and carbonated drinks usually have a lot of sugar, which is very harmful to our tooth enamel as it creates favorable environment for plaque formation. Besides, the majority of soft and carbonated drinks are very acidic, which is also very damaging and harmful to our teeth.

2. Citrus fruit. Occasional consumption of oranges, lemons or other citrus fruit can not bring to a huge damage to our teeth. However, these fruit are very rich in natural acids, which if consumed regularly can cause softening and erosion of tooth enamel, making our teeth weaker and less healthy. Therefore those, who love eating oranges or tangerines should make a habit of using mouthwash after eating these fruits. In addition, it is recommended to drink orange juice using a straw.

3. Tea and coffee. If you have a habit of drinking 3-4 cups of black coffee or black tea a day, you’ll need to pay increased attention on the color of your teeth. Along with tobacco smoking, regular consumption of coffee or black tea are the leading causes of tooth darkening, straining and discoloration. Rich in tannins and some acids, tea and coffee may have destructive effects on our teeth, but if you want to stick with your habit and still have a shiny smile, add a little milk to your daily cup of tea or coffee. Milk is proven to be able to neutralize negative effects of tannins on out teeth.

4. Wine. Wine is actually a controversial factor which has both positive and negative effect on our dental health. As a natural antiseptic, red wine can be used to lower the risks of dental plaque formation and preventing tooth decay. At the same time, wine is also rich in sugar and acids, which are damagingĀ  to our tooth enamel. Besides, recent studies have shown that a regular consumption of wine is linked to increased risks of tooth staining. Therefore, drink plenty of water after drinking wine to remove harmful components from your teeth.

5. Diet pills. The effects of diet pills sometimes cause reduced production of saliva by the glands. As a result, we have dry mouth and a very favorable environment for various bacteria and dental plaque formation. Remember that for an effective weight loss it is enough to combine a healthy balances diet with sufficient amounts of exercise. It is the healthiest solution, both for your body and teeth.

Sugar-Free Foods Can Be Harmful To Our Teeth

Many of us frequently use sugar-free products with the aim to protect our teeth from harmful effects of sugar. Especially, parents like giving sugar-free bars and products to their children in order to lower the risks of damaging children’s teeth. However, the specialists ring the bells saying that such products are very often overfilled with acidic and other types of additives, which can be not less but even more harmful to our teeth than sugar. The same can be said about sugar-free drinks.

Sugare Free FoodsWhen choosing a product in the markets or shops, modern consumers usually look ate sugar content. But they do not realize that other ingredients can also be as bad. The specialists tested more than 85 popular sugar-free snacks, including the ones of such popular brands as Kellogg‘s and Nestle. It turned our that all of those products have harmful acidic elements, and the same can be said about commercial orange juice. Brad Schmitt, a nutritionist, comments on the study: “Kids love their muesli bars and fruit snacks but parents should limit them to be a once-a-week treat.”

Acid damage is sometimes more dangerous than sugar damage, because it not only weakens the enamel and erodes the minerals in it. It also extremely increases teeth sensitivity and makes tooth enamel more vulnerable for harmful activity of sugars. Many specialists consider acid erosion even more dangerous than damageĀ  from sugar as the former causes enamel demineralization, and the latter is more likely linked to cavities and tooth decay. That is why we all should be careful of consuming sugar-free foods thinking that the risks of damaging teeth are minimized.
