Why Do We Brush Twice a Day?
You have probably heard your dentist say—on more than one occasion– that you should brush your teeth at least twice a day. However, you may not know why brushing two times daily is important. Here are a few reasons for this popular dental recommendation:
Plaque is continually produced.
When you eat, leftover bits of food mix with the bacteria inside your mouth to form plaque. The filmy, sticky substance coats your tooth enamel and gums. Although the development of plaque is a continual natural occurrence, the substance can cause a great bit of damage to your teeth.
Because plaque adheres to your teeth and gums, it places bacterial acid in direct contact with them. The bacteria within the plaque feast on the food particles in the mixture. As the microbes feed, they digest the food and release acid as a by-product. Since the acid is released adjacent to the tooth enamel, plaque can be highly damaging.
Just as acid is corrosive to most other substances, it also eats away at your enamel. This results in tooth decay. The longer the acid remains in place, the greater your chance of needing a dental appointment to fill a cavity. Twice-daily brushing removes the plaque before it can damage your pearly whites.
