What is a Double Cavity?

A cavity is a hole in the tooth. The hole is the result of bacteria eating away at the tooth. When two teeth are next to each other, it is possible for both of them to end up with a cavity. If the cavity is on both sides of the gap between two teeth, it is called a double cavity. That will require both teeth needing a filling.

How Flossing Prevents This
