The aim of root canal treatment (also called “endodontic” treatment) is to save a tooth that has been badly damaged due to decay, disease or injury.
Symptoms may include pain, sensitivity to heat or cold. To save the tooth, root canal treatment is needed when the pulp becomes severely inflamed or infected. Several visits are required to complete the treatment. After the tooth’s nerve is removed, the tooth is not “dead”. The tooth can survive without the pulp because it is nourished mostly by tissues around it.
