Cavity (Dental caries)

Dental Caries

Tooth decay is very common. Everyone has germs in their mouth. After you eat, you have food pieces left on your teeth. The germs combine with the food to make acid. The acid can eat away the protective enamel of the tooth and cause tooth decay. You can have decay on the tooth surface or deep into the tooth. Because it takes time for the acid to break through the enamel, you may not notice any signs with early decay. Only the dentist can see it with an x-ray. If you do have signs, it is because the decay is going deep into the tooth.
