What is Dental Decay?

Dental decay is the erosion of tooth enamel caused by acids produced by bacteria in the mouth. Plaque, a sticky film formed from bacteria, food particles, and saliva, can build up on the teeth, especially in areas that are difficult to clean, such as cracks, pits, and between teeth.

Symptoms

Dental decay may lead to pain or sensitivity to hot, cold, or sweet foods.

Treatment

The standard treatment for dental decay is a filling, typically made of composite resin (tooth-colored material). For large cavities, if the remaining tooth structure is insufficient to support a filling, the dentist may recommend a crown after removing the decay.
