Tooth decay (or caries) is what happens when holes form in parts of the enamel of the teeth.

What causes tooth decay?

Tooth decay is mainly caused by a build-up of plaque. The bacteria in the plaque react with sugars and starches in food to form acids. The acids are kept next to the teeth by the sticky plaque and these dissolve the tooth enamel.

What happens if I have tooth decay?

If you have tooth decay you may need fillings, crowns or inlays.
