Root canal treatment is a common dental procedure used to treat and save a tooth that is damaged or infected at the pulp level. During the procedure, the damaged or infected pulp is removed, and the tooth is cleaned and sealed to prevent further infection.
There are several reasons why the pulp may become infected or inflamed, including deep decay, trauma, cracks or fractures in the tooth, or extensive dental work that affects the pulp. Symptoms of pulp damage may include pain, sensitivity to hot or cold, swelling, discoloration, tenderness of the gums, or a bad taste in the mouth. However, sometimes there are no symptoms at all.
