In short: Yes, a dental abscess is serious and needs prompt treatment — it’s a pocket of infection that can spread. Signs include severe throbbing pain, swelling of the gum or face, a bad taste, fever, and tenderness. If swelling affects your breathing, swallowing or spreads to the eye or neck, seek emergency care immediately.
A dental abscess is a collection of pus caused by a bacterial infection, usually from an untreated deep cavity, a cracked tooth, or advanced gum disease. It should never be ignored, because the infection can spread to the jaw, face and, rarely, become life-threatening.
Signs of a dental abscess:
- Severe, throbbing toothache that may spread to the jaw, ear or neck.
- Swelling of the gum, face or cheek — sometimes a visible “gum boil.”
- Pain when biting or touching the tooth, which may feel loose.
- A bad taste in the mouth or bad breath, especially if the abscess bursts and releases foul-tasting pus.
- Sensitivity to hot and cold.
- Fever and feeling generally unwell.
- Tender, swollen glands in the neck.
Sometimes the throbbing pain suddenly stops — this can mean the nerve has died, but the infection is still there and still spreading. So relief of pain does not mean it’s cured.
An abscess will not heal on its own and needs a dentist to drain the infection and treat the source — usually a root canal or extraction, sometimes with antibiotics. Seek emergency care immediately if you have swelling that affects breathing or swallowing, spreads to your eye or neck, or comes with a high fever — these are signs the infection is spreading dangerously.
