Abscess (Dental)

An Abscess (Dental) is a pus-filled pocket that forms when bacteria infect the tooth pulp or the periodontal tissues surrounding a tooth. There are two common types — a periapical abscess at the tip of a root and a periodontal abscess in the gums — and both can cause intense, throbbing pain, visible swelling, a bad taste or odor in the mouth, sensitivity to hot or cold, and sometimes fever or swollen lymph nodes if the infection extends beyond the local area.

Diagnosis usually involves a clinical examination and dental X-rays to determine the origin and extent of the infection. Treatment depends on the cause and severity and may include drainage of the abscess, root canal therapy or extraction of the affected tooth, plus antibiotics when the infection has spread; prompt dental care reduces pain, prevents complications and, combined with good oral hygiene, lowers the risk of recurrence.
