Your teeth are meant to last a lifetime. Years ago, diseased or injured teeth were usually pulled. But today, a tooth can often be saved through root canal (endodontic) treatment.
Endodontics (en-do-DON-tics) is the branch of dentistry that deals with treating diseases or injuries to the dental pulp. An endodontist is a dentist who specializes in root canal and other endodontic treatments.
