Root canal therapy or Endodontics is a dental procedure that treats severely decayed or broken teeth. When the pulp tissue and nerve endings deep inside the tooth have been infected, the endodontic procedure involves removing the decayed tissue and thoroughly cleaning out the root canals. Once the root canals are sealed, the rest of the tooth is prepared for restoration and a new crown is then fitted.
Successful treatment helps to save the tooth from extraction. If left untreated an abscess can occur leaving the patient in severe pain and the possibility of extraction.
