What is a Cavity?

What is a cavity and how do you get a cavity? A cavity is simply a hole in a tooth. These holes can be as tiny as a tip of a sewing needle. A cavity allows for bacteria to collect under the surface of a tooth and grow and cause the hole to enlarge.

How does a cavity form? Your mouth contains thousands of different types of bacteria. Most of the bacteria in your mouth is harmless but there are a few types of bacteria that do cause harm to your teeth. These harmful bacteria use sugar as a fuel and in the process of using the sugar create acid as a byproduct. As a collection of these bacteria gather on a tooth, the amount of acid produced grows substantially. The acid produced on the tooth causes the minerals in the tooth to dissolve and be removed from the tooth! As the minerals are removed it causes microscopic holes to form. The longer the bacteria goes without being removed, the larger the holes become until eventually it becomes a cavity.

In our next blog we will discuss ways to stop a cavity and ways we can treat cavities.
