A study published in the ACS Applied Materials & Interfaces, scientists discovered a substance that adheres to the outer layers of tooth enamel to repair erosion. This is promising news since 3 out of 4 people report experiencing tooth sensitivity. Sensitivity to temperature, brushing or even breathing in cold air is caused by enamel eroding. The weakened enamel allows the nerve to be stimulated, resulting in a sharp pain. Erosion to some degree is inevitable. Brushing, acidic, foods, plaque, and whitening treatments all wear down on the minerals that maintain the strong barrier of enamel. Sensitivity may not be able to be prevented, but it can be treated defensively by avoiding causes and using products designed for sensitive teeth.
Avoid Acidic Foods
Regular exposure to acidic food and/or beverages wears down the enamel on teeth. Foods high in acid include; pickles, citrus fruits, tomatoes, coffee, alcohol, and tea. If these foods are consumed, rinsing afterwards will reduce the amount of acid that is able to damage enamel. Drinking acidic beverages with a straw is another way to prevent extended contact of acid.
Use Toothpastes Created for Sensitive Teeth
These toothpastes work by limiting the sensation that is transmitted from the tooth’s surface to the nerve. Common ingredients include strontium acetate and potassium nitrate. Strontium acetate is similar to calcium and works to block tubules that allow fluid to reach the nerve from the surface of the tooth. Potassium nitrate prevents the nerve from transmitted pain signals to the brain. It works progressively and should be used regularly over an extended period of time in order for maximum benefits to be achieved.
Brush Gently and Regularly
Switching to a softer bristle toothbrush does not mean compromising on effectiveness. In fact, enamel can be damaged by the abrasiveness of harsh bristles. Keeping the surface of teeth clean lessens the opportunity of acids to damage enamel. Regular in office cleanings are another important way to defend against sensitivity.
Treating tooth sensitivity can allow you to enjoy your favorite foods and beverages pain free. No longer would you have to wait for a drink to cool or eat carefully around an ice cream. The same cause of tooth sensitivity, erosion of enamel, also leads to other tooth and gum issues. The enamel is our protection against cavities and the the development of gum disease. Taking steps to protect against its continued erosion, even defensively, is a way to improve overall oral health.
