A dental abscess is a bacterial infection trapped in a sealed space — usually at the root tip of a tooth (periapical) or in the gum next to a tooth (periodontal). Untreated, it can spread into the jaw, neck, sinuses or bloodstream.
Catching it early matters.
Signs to watch for
- Throbbing pain or pressure that won't quit
- A pimple-like bump on the gum, sometimes draining pus
- Bad taste in the mouth or persistent bad breath
- Swollen cheek, jaw or lymph nodes
- Fever, fatigue, generally feeling unwell
- Sensitivity to chewing or hot/cold
- A loose tooth in the affected area
What you should do
- Don't squeeze or pop the bump. It pushes bacteria deeper.
- Rinse with warm salt water several times a day.
- Take ibuprofen for pain (if not contraindicated).
- Cold compress on the outside of the cheek for swelling.
- Book an appointment online the same day.
When it's an ER visit, not a dentist visit
- Facial swelling extending toward the eye or down the neck
- Difficulty breathing or swallowing
- Fever above 101°F with rapid heartbeat
- Severe headache, blurred vision, confusion
These can indicate the infection is spreading systemically — go to the ER immediately.
How we treat abscesses
Three things happen in the same visit:
- Drainage. An incision releases the pus, immediately cutting the pressure and most of the pain.
- Antibiotics. Usually amoxicillin, or clindamycin if you're penicillin-allergic. Antibiotics control infection but don't replace mechanical drainage.
- Definitive treatment. Root canal to save the tooth, or extraction if it can't be saved. Sometimes scheduled for a follow-up; sometimes done the same visit.
The myth of antibiotics alone
"Just give me a Z-Pak" doesn't fix an abscess. Antibiotics knock infection back temporarily, but the source — usually an infected nerve or a deep gum pocket — is still there. The abscess returns, often more aggressive than before. Drainage plus definitive treatment is the cure.
If you have any of the symptoms above, don't wait. Book an appointment online.
