Cavities, or tooth decay, is the destruction of your tooth enamel, the hard, outer layer of your teeth. It can be a problem for children, teens, and adults. Plaque, a sticky film of bacteria, constantly forms on your teeth.
What Causes Cavities
When you eat or drink foods containing sugars, the bacteria in plaque produce acids that attack tooth enamel. The stickiness of the plaque keeps these acids in contact with your teeth and over time the enamel can break down. This is when cavities can form. A cavity is a little hole in your tooth.
Brush twice a day with a fluoride toothpaste.
Clean between your teeth daily with floss or interdental cleaner.
Eat nutritious and balanced meals and limit snacking.
Check with your dentist about the use of supplemental fluoride, which strengthens your teeth, and about use of dental sealants (a plastic protective coating) applied to the chewing surfaces of the back teeth (where decay often starts) to protect them from decay.
