Keeping this in view, what is a cavity?

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.

Also Know, what does a cavity do to your teeth? Cavities are what you get from tooth decay -- damage to the tooth. The bacteria, acid, food debris, and your saliva combine to form plaque, which clings to the teeth. The acids in plaque dissolve the enamel, creating holes called cavities.

Similarly, you may ask, what is a cavity made of?

Is tooth decay the same as a cavity?

Decay is a progressive tooth disease caused when enamel is compromised and the tooth is exposed to harmful oral bacteria. A cavity is the hole that forms in your tooth as the decay works its way through your tooth structure.
