An endodontist is a dentist who specializes in root canal treatment. Endodontic treatment is a procedure performed to remove damaged tissue from inside the root canals of a tooth.

Sometimes the pulp inside your tooth becomes inflamed or infected. This can be caused by deep decay, repeated dental procedures on the tooth, a crack or chip in the tooth, or a blow to the tooth.

Signs to look for include pain, prolonged sensitivity to heat or cold, discoloration of the tooth, and swelling and tenderness in the nearby gums. But sometimes, there are no symptoms.

The endodontist removes the inflamed or infected pulp, carefully cleans and shapes the inside of the tooth, then fills and seals the space. Afterwards, you return to your general dentist, who will place a crown or other restoration on the tooth to protect it and restore it to full function.

You should not chew or bite on the treated tooth until you have had it restored by your general dentist because your tooth could fracture. Otherwise, just practice good oral hygiene - brushing, flossing and regular checkups and cleanings. Endodontically treated teeth can last for many years, even a lifetime.
