The pulp, or nerve of the tooth, is important during the tooth's development. But once a tooth is fully mature, the tooth can survive without the pulp.
When a crack or cavity exposes the nerve to oral bacterial, an infection of the nerve will result, eventually causing an abscess. Periodontal (gum) disease or a severe blow to the tooth can also cause damage to the pulp. Endodontic therapy removes the damaged pulp and permits the tooth to return to a healthy condition.« Go Back
