Smile Dental abscess: warning signs and what to do
A dental abscess is a pocket of pus caused by a bacterial infection in or around a tooth. It does not go away on its own, so see a dentist the same day if you suspect one.
Signs of a dental abscess
- Severe, throbbing toothache that can spread to the jaw, ear or neck.
- Pain when chewing or biting, or sensitivity to hot and cold.
- A swollen, red area on the gum, sometimes like a small boil.
- Swelling in the face or cheek and tender glands in the neck.
- A bad taste in the mouth, bad breath, or a fever.
If the abscess bursts, the pain may suddenly ease and you may notice a salty, foul-tasting fluid. You still need treatment.
Why it needs a dentist
Painkillers can ease discomfort but do not remove the infection. A dentist may drain the abscess, treat the tooth with a root canal or remove it, and sometimes prescribe antibiotics.
Go to emergency care if
Seek emergency help if you have a high fever, swelling of the face or neck that is spreading, or trouble swallowing or breathing. An untreated infection can spread to other parts of the body.
How to lower the risk
- Brush twice a day with fluoride toothpaste and clean between your teeth daily.
- Treat cavities early. Learn the early signs of cavities.
- Go for regular dental check-ups.
