Tooth Decay and Cavities

Tooth decay is caused by plaque, which is caused by bacteria that is not removed regularly by brushing and flossing daily. A cavity is a hole in the tooth caused by tooth decay. Cavities usually do not cause any symptoms until they are very large.

Symptoms include:

• Toothache -- particularly after sweet, hot, or cold foods and drinks
• Tooth sensitivity
• Visible pits or holes in the teeth

An untreated cavity can result in a tooth abscess. Untreated tooth decay also destroys the internal structures of the tooth (pulp) and ultimately causes the loss of the tooth.
