Periapical (root-tip) Abscess

A periapical (root-tip) abscess is a pocket of infection at the base of a tooth's root. The tooth becomes abscessed after the pulp (nerve) of the tooth becomes infected. A periapical abscess is usually caused by deep decay or an accident (trauma to the tooth involving nerve damage). A periapically abscessed tooth will require either Pulp Therapy or an Extraction. In some cases an antibiotic will also be prescribed.

Lateral Abscess

A lateral abscess is similar to a periapical abscess, but develops along the lateral surface of the tooth's root. In this case, the infection comes from outside the tooth instead of from within. A lateral abscess can either be gingival (located near the gum line) or periodontal (located deeper in the periodontal tissues). Since most cases of lateral abscess are due to periodontitis (gum disease), treatment is part of an overall periodontal (gum) treatment program.

All Abscesses

An abscessed tooth is usually sensitive or painful. The discomfort is what normally alerts the patient to the problem. Occasionally, an abscess may be detected on an x-ray and treated before the patient experiences any discomfort. Left untreated, an abscess may compromise the immune system and in some cases may become life-threatening.
