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.
