The need for root canal treatment should not be associated with fear. Root canal treatment is the last step when trying to save a tooth before extraction. If left untreated, the growing decay will result in a bigger infection and make the tooth unrestorable.
Root canal therapy is performed when the pulp, the nerves and blood vessels inside the tooth, becomes infected or damaged. During root canal therapy, the pulp is removed, and the inside of the tooth is cleaned and sealed. With the proper anesthesia, you shouldn’t feel anything during the entire procedure.
