Facial or Jaw Swelling: Causes & When It's an Emergency

Tooth Infection or Abscess

The most common dental cause is bacteria from a decayed or damaged tooth spreading into surrounding tissue.

Gum Infection

Advanced gum disease can cause localized swelling along the jawline. Recent dental procedure — Extractions, root canals, and other procedures often cause temporary, expected swelling.

Injury or Trauma

A blow to the face or jaw can cause swelling from soft tissue damage.

Salivary Gland Issues

Blocked or infected salivary glands can cause swelling near the jaw or under the chin.

Wisdom Tooth Complications

Impacted or infected wisdom teeth commonly cause swelling in the back of the jaw.
