A tooth abscess is an infection caused by tooth decay, periodontal disease or a cracked tooth. Symptoms of an abscessed tooth can include pain, swelling, redness in the gums, bad taste in the mouth or fever. Left untreated, the abscess can lead to a serious infection in the jaw bone, teeth, and surrounding tissues.
If you have an abscessed tooth, it won’t get better on its own. You will need treatment from a dental specialist who can help save your tooth.
