A dentist drains the abscess and treats the cause — usually a root canal or an extraction. Most practices keep same-day slots for swelling.

A dental abscess with swelling. This one is urgent.
An abscess is a pocket of pus from an infected tooth. Swelling that reaches your eye, your neck or under your jaw is a spreading infection and can become dangerous within hours — that is hospital territory, not a next-week appointment.
Same day — emergency room if swelling spreads
Step by step
Do this now
-
Call a dentist and say you have facial swelling
Practices triage swelling ahead of routine pain. If they cannot see you today, ask where to go instead.
-
Photograph the swelling
A phone photo with a timestamp helps the clinician judge how fast it is progressing, especially if you are sent to urgent care.
-
Keep your head raised and drink fluids
Stay upright and hydrated. Do not lie flat if the swelling is under your jaw.
-
Take painkillers and any prescribed antibiotics exactly as directed
Finish the course. Antibiotics buy time for the dentist to drain or treat the tooth; they do not cure it alone.
-
Go to the emergency room if it is spreading
Swelling that closes the eye, spreads down the neck, or comes with fever, a stiff neck or trouble swallowing needs hospital assessment today.
Avoid
What not to do
- Squeezing or popping the gum boil
- Applying heat to the face
- Waiting for it to drain by itself
- Flying or diving with untreated facial swelling
- Stopping antibiotics when you feel better
Where to go
Dentist or emergency room?
Go to an emergency room now if the swelling is spreading to your eye or neck, you have a fever, you cannot swallow or open your mouth, or you feel generally unwell. Dental infections can become life-threatening.

Abscess and swelling — questions people ask
How serious is a dental abscess?
Very. An untreated abscess can spread to the face, jaw and neck. In rare cases the infection reaches the bloodstream or blocks the airway, which is a medical emergency.
Will it drain on its own?
Sometimes it bursts through the gum and the pain eases, but the infection remains inside the tooth. It will come back, usually worse.
Can I fly with an abscess?
Do not fly with untreated facial swelling. Pressure changes worsen pain and the infection can progress quickly away from help.
Do I need antibiotics before treatment?
Sometimes, if the infection is spreading or you have a fever. Antibiotics are an adjunct; the tooth still needs draining and either a root canal or removal.
What does it look like?
A pimple-like bump on the gum, a bad taste, swelling in the cheek or under the jaw, and often a throbbing tooth that hurts when tapped.
