1 After you eat, tiny bits of food are left between your teeth. Bacteria grow on them, forming plaque.  The bacteria digest the carbohydrates (sugars and starches) in food and produce an acid. This acid dissolves the enamel (the hard outer layer of your tooth) and a hole (cavity) is formed.
its actually pretty simple:cavities are caused by bits of food left in your teeth over night. the food form plaque, which turns into acids that drill a hole to your teeth. bas â¦ ically, the best way to avoid it is to floss and brush your teeth after each meal, and especially before you go to bed.-rays are also often useless in detecting decay on the surface of the tooth directly facing the x-ray. If you doubt your dentist, please get a second opinion. Its your right, and its your mouth! 1 person found this useful.
