A tooth abscess is the result of pus collecting in the tissue at the base of a tooth. This can happen for a variety of reasons, including infection caused by decay, damage, or advanced gum disease. Abscesses are usually accompanied by extreme pain and swelling in the jaw. If left untreated, tooth abscesses can spread to other areas of the body and cause dangerous complications like blood infection, brain abscesses, pneumonia and infection of the jaw and facial tissue.
Tooth abscesses are generally treated with antibiotics and drainage, to cure the infection and remove infected material. Once the infection is cured, a root canal procedure can be performed to restore the tooth. If the tooth cannot be restored, it is extracted.
Patients experiencing severe dental pain or swelling should see their dentist as soon as possible.
