Tooth Abscess

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. We offer emergency appointments for dental abscesses.

Emergency Care Before Your Visit

A tooth abscess requires professional treatment, but there are steps you can take to manage your symptoms before reaching the dental office. Take over-the-counter pain relievers like ibuprofen to reduce both pain and swelling — follow dosage instructions carefully. Rinse gently with warm salt water several times a day to help draw the infection toward the surface and reduce bacterial levels. Avoid applying aspirin directly to the gum, as this can burn the tissue. Do not attempt to pop or drain the abscess yourself, which can spread the infection. Apply a cold compress to the outside of your cheek to reduce facial swelling. Avoid hot or cold foods and drinks, and eat on the opposite side of your mouth. If you experience fever, difficulty swallowing, or rapid swelling, go to the emergency room immediately — these are signs that the infection may be spreading to dangerous areas.

Dangers of an Untreated Abscess

A tooth abscess will never resolve on its own and is one of the most dangerous dental conditions if left untreated. The infection can spread from the tooth root into the jawbone, causing osteomyelitis — a bone infection that requires prolonged antibiotic treatment and sometimes surgery. In severe cases, the infection can travel to the neck and throat, creating a condition called Ludwig's angina that can block the airway and become life-threatening within hours. Bacteria from a dental abscess can also enter the bloodstream, causing sepsis — a systemic infection that requires emergency hospital treatment. Even if the pain from an abscess temporarily subsides, this does not mean the infection has cleared. The nerve may have died, but the infection continues to spread silently through surrounding tissues. Untreated abscesses can also lead to the formation of fistulas — small tunnels through which pus drains into the mouth or through the skin of the face. Protecting yourself is straightforward: treat cavities early before they can progress to abscesses, and seek immediate care when symptoms appear.
