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.
  I don't agree with the bottom answer.   To make it simple, you can view cavities in two ways. If they appear on the surface of the tooth, any dentist can see it direc â¦ tly with his or her own eyes. But if the cavity is between two teeth, or under a filling, the cavity can only be seen on an x-ray.epending on how big is the cavity, the drilling takes between 5 and 15 minutes. Filling goes by very quickly and is only about 3-5 minutes and polishing is also about 5 minutes.
