Tooth Decay

The softening of the tooth enamel caused by permanent damage due to bacteria producing acids is called tooth decay. When you eat sugary food, the bacteria in the mouth break down the sugar and produce acid, which demineralizes the tooth surface resulting in a cavity. Some of the factors that increase the risk of tooth decay are dry mouth, poor oral hygiene, frequent snacking, eating sticky foods, etc.
