Abscessed Tooth Treatment: How Dentists Stop Infection Fast

The typical symptoms are a severe toothache, swollen gums or face, pus or a bad taste in the mouth, and sometimes fever or a general feeling of illness. The pain is often constant and throbbing rather than triggered only by hot or cold. An abscess is a bacterial infection and is considered a dental emergency, so these symptoms should not be delayed.

Treatment starts with draining the infection to relieve pressure and pain, with antibiotics prescribed when they are necessary. The tooth itself is then addressed through root canal treatment, which removes the infected nerve tissue, or through extraction when the tooth cannot be saved. Antibiotics alone do not cure an abscess, because the source of the infection inside the tooth remains.

An untreated abscess can spread infection into the jaw, the sinuses, or the bloodstream, which turns a dental problem into a medical one. Swelling that affects breathing or swallowing needs emergency medical attention. Even when the pain temporarily eases, the infection is usually still present, so the absence of pain is not evidence that the abscess has resolved.

A tooth abscess does not resolve on its own, because the bacteria are sheltered inside the tooth where the immune system and blood supply cannot reach them. Pain may come and go as pressure builds and releases, which is easily mistaken for improvement. Definitive treatment requires a dentist to drain the infection and then treat or remove the affected tooth.
