Endodontic treatment or root canal treatment.
Root canal treatment is performed by the dentist to relieve pain that is caused by the nerve pulp of a tooth that would otherwise have to be extracted.
Usually the pulp becomes painful due to decay, trauma, or fractures of the tooth that extend to the nerve pulp causing the nerve to die and infection to occur. Sometimes the infection may present as just pain, or even swelling of the face.
Please Note: If you are having difficulty swallowing or breathing we strongly recommend that you attend the nearest emergency room.
