Tooth Abscess & Swelling
A dental abscess is a pocket of bacterial infection at the tooth root or in the gum. It can smolder as a dull ache with a pimple-like bump, or escalate to facial swelling — and facial swelling is where dental problems turn genuinely dangerous.
Why antibiotics alone don't fix it
Antibiotics can knock down the surrounding infection, but the source — infected pulp or a deep pocket — persists until treated with a root canal, drainage, or extraction. An abscess that 'got better' on antibiotics alone reliably returns. A draining bump on the gum that stops hurting has not healed; it has found an exit.
The danger signs
Swelling spreading toward the eye, under the jaw, or down the neck; fever with swelling; difficulty opening the mouth, swallowing, or breathing — these are emergency-room territory, immediately. Dental infections in these spaces can compromise the airway. Handle the danger at the hospital, then treat the tooth.
- Facial swelling spreading toward the eye or down the neck
- Fever with facial swelling
- Trouble breathing or swallowing
- Bleeding that won't stop with firm pressure
- Jaw trauma or a suspected broken jaw
