Cavities are results of decaying teeth. When teeth decay causes destruction of the structure of the teeth. Tooth decay can affect both the enamel which is the outermost coating of teeth as well as the dentin layer of teeth. Tooth decay can give way to tooth ache. When food containing carbohydrates such as bread, milk, cereals, fruits, soda, candy or cakes are left on the tooth, tooth decay occurs. Bacteria residing in the mouth digest this food and convert it into acid. The acid, food debris, bacteria and saliva together form plaque which clings to the teeth. The acid present in plaque, dissolve the enamel surface of the teeth which creates hole in the teeth which are called cavities. There are several factors which can cause cavities.
