Root canal treatment is a procedure that makes it possible to save a tooth and avoid extraction.
Root canal treatment is necessary when the pulp inside the tooth, which consists of nerve tissue, blood vessels, and connective tissue, becomes inflamed or infected by bacteria. There are many possible causes of inflammation or infection: deep decay, numerous dental procedures, a crack in the tooth, or a missing fragment. In addition, a strong blow to the tooth can cause irreversible damage to the pulp even if there are no visible cracks or fractures in the tooth. If pulp inflammation or infection is left untreated, it can cause pain and lead to the formation of an abscess. Signs of pulp damage include pain, prolonged sensitivity to hot and cold, discoloration of the tooth, and swelling and tenderness of the gums. There are also cases where no symptoms occur at all.
A root canal specialist removes the inflamed or infected pulp, carefully cleans and shapes the root canals inside the tooth, and then fills and seals them. Later, the tooth will need a crown or other restoration in order to protect it and restore full functionality. After restoration, the tooth functions like any other tooth.
