Commonly known as “root canal therapy,” endodontic treatment is performed when the pulp is infected or inflamed. The infected or inflamed tissue is carefully cleaned and the tooth is filled with a biocompatible material. 

During this procedure, the crown of the tooth is opened, allowing the doctor to access the root canal. The pulp tissue in the infected root canal is removed and the canals are cleaned. Once any infection has completely cleared up, which could take a few days or longer, the root canals are sealed to prevent bacteria or debris from entering the root canals and causing further infection. Finally, the crown of the tooth is sealed with a filling or crown.
