A cavity is a hole that can grow bigger and deeper over time. Cavities are also called dental caries (say: KARE-eez), and if you have a cavity, it's important to get it repaired. But why would your tooth develop a hole? Blame plaque. That's a sticky, slimy substance made up mostly of the germs that cause tooth decay.

Some bacteria are present in our mouth which are not harmful. But if we donot brush our teeth then many harmful bacteria also grow which break down the sugars in our food and releases acid. These acids may damage our teeth, this is known as tooth decay. Sometimes a tiny hole appears on the surface of the teety which slowly gets bigger. This is called cavity.
