Tooth decay is damage that occurs when germs (bacteria) in your mouth make acids that eat away at a tooth. It can lead to a hole in the tooth, called a cavity. If not treated, tooth decay can cause pain, infection, and tooth loss. A tooth has three layers. The hard outer layer is called enamel.
Tooth decay is a destruction of the tooth enamel. It occurs when foods containing carbohydrates (sugars and starches) such as milk, pop, raisins, cakes or candy are frequently left on the teeth. Bacteria that live in the mouth thrive on these foods, producing acids as a result.ooth decay is a process created by the bacteria that live in our mouths. The bacteria use the food that passes through our mouths to create a sticky substance called plaque. The plaque, which is full of bacteria, releases acid onto the teeth.
