What Is a Tooth Abscess?

A tooth abscess is a pocket of pus caused by a bacterial infection. It can occur at the tip of the root (periapical abscess) or in the gums beside the root (periodontal abscess). A dental abscess is a serious condition that won't resolve on its own and requires prompt professional treatment.

Common Causes

• Untreated tooth decay reaching the pulp (nerve)
• Cracked or broken tooth allowing bacteria inside
• Failed or old dental work
• Gum disease creating deep pockets of infection
• Trauma or injury to the tooth
• Weakened immune system

When to See a Dentist

A tooth abscess is a dental emergency. Seek immediate care if you experience severe, persistent toothache, sensitivity to hot and cold, fever, swelling in your face or cheek, tender or swollen lymph nodes, difficulty breathing or swallowing, or a sudden rush of foul-tasting fluid in your mouth.

Emergency Abscess Treatment

Treatment involves draining the abscess and eliminating the infection. Depending on the severity, this may include root canal therapy to save the tooth, extraction if the tooth can't be saved, or incision and drainage of the abscess. Antibiotics may be prescribed.
