It is a localized collection of pus (infection) that forms at the root end of a tooth or in the gum tissues surrounding a tooth

Untreated tooth decay, deep cavities, cracked teeth, or severe gum disease allow bacteria to invade the inner pulp or supporting structures leading to infection

A severe, throbbing toothache, sensitivity to hot and cold, tender or swollen gums, facial swelling, a bad taste or odor, and sometimes a fever.

Seek immediate emergency care if you experience swelling that makes it hard to breathe or swallow. Swelling that spreads to the neck or eye can be life threatening.

Unfortunately, no. An abscess does not heal by itself; even if the pain stops because the tooth nerve dies, the underlying infection remains and can spread or worsen over time.

Treatment options include draining the pus, performing a root canal to save the tooth, extracting the infected tooth, or prescribing antibiotics (although antibiotics alone do not cure the root cause of the infection)

Rinse gently with warm salt water, take over-the-counter pain relievers as directed, and avoid placing heat or pressure on the area
