Cavities

A cavity is a small hole that forms in a tooth. Cavities happen when bacteria in your mouth make acid that eats away at your tooth. Brushing and flossing can help prevent cavities.

How Cavities Form

Bacteria live in your mouth and love to eat sugar. When they eat sugar, they make acid. This acid attacks the hard outer layer of your teeth called enamel. Over time, the acid makes a hole.

If you do not brush and floss, a sticky film called plaque builds up on your teeth. Plaque is full of bacteria that cause cavities.

Preventing and Treating Cavities

Brush your teeth twice a day with fluoride toothpaste. Floss once a day to clean between your teeth. Try not to eat too many sugary snacks and drinks.

If you do get a cavity, a dentist can fix it with a filling. The dentist removes the decayed part and fills the hole. Regular checkups help catch cavities early.
