Endodontic treatment is necessary when the pulp, the soft tissue inside the root canal, becomes inflamed or infected. The inflammation or infection can have a variety of causes: deep decay, repeated dental procedures on the tooth or a crack or chip in the tooth. In addition, an injury to a tooth may cause pulp damage even if the tooth has no visible chips or cracks. If pulp inflammation or infection is left untreated, it can cause pain or lead to an abscess. Treatment is generally not significant, in spite of its reputation. Dr. Schnall utilizes computer-controlled anesthetic delivery and rotary endodontics to make the treatment more comfortable for the patient.
