The destruction of tooth structure both the enamel and dentin layer is tooth decay. This occurs when foods containing carbohydrates are left on the teeth. The bacteria that live in the mouth melts these foods turning them into acids. The combination of bacteria, acid, food and saliva forms plaque which clings to the teeth and dissolves the surface that creates holes in the teeth called cavities. Cavities occur as a result of tooth decay.
A lot of people have this misconception that cavities only affect children. What they don’t know is that cavities is an adult problem too and leads to recession of gums, often associated with gingivitis that can expose tooth root to plaque.
In a number of different ways depending on the extent of tooth decay, cavities can be treated. If it is not extensive, the decayed portion of the tooth is removed by drilling and replaced with a filling. Restorative materials used in filling are considered safe.
