In your mouth, bacteria are constantly present. These bacteria, however, are not harmful until they come in contact with sugar. They consume the sugar, turning it into an acid. The acid is what eats away your tooth structure and causes cavities.
When cavities form, your dentist will use his drill to cut out all of the decayed tooth structure. This ensures that the acidic residue left by the bacteria will not spread to your bone or other teeth, causing further complications.
After drilling out the decayed tooth, your dentist will use either a tooth colored material or a silver looking filling with a material called amalgam. He will carve the filling material until it mimics the anatomy of your original tooth structure.
Remember, by using an electric toothbrush (Sonicare, or Oral B, for example) you may avoid having to get any cavity fillings!
