How are cavities caused?
Cavities are holes in the teeth that are caused by tooth decay. Decay occurs when bacteria in the mouth use the carbohydrates (sugars and starches) found in certain foods to make acid. This acid eats away at the tooth enamel, causing pitted areas or holes. Young children are more at risk for cavities than adults because the enamel or outer surface of the baby teeth is thinner than adult teeth.
