What is dental abscess?
A dental abscess is a painful collection of pus caused by a bacterial infection in a tooth or the gum around it. It typically causes severe, throbbing pain, swelling, and sometimes a fever. A dental abscess won't heal on its own — you need to see a dentist urgently for drainage and antibiotics.
When NHS resources suggest seeing a GP
- You think you have a dental abscess.
- Do not go to a GP surgery as they will not be able to give you dental treatment.
Self-care information from NHS
- Call 111 or get help from 111 online – they can tell you where you can get help for your symptoms.
- Find a dentist near you – ask if you can have an emergency appointment.
- There are some things you can do to help while you wait for treatment if you have pain from a dental abscess.
- Brush your teeth with fluoride toothpaste at least twice a day – spit after brushing, do not rinse.
- Clean between your teeth every day using floss or interdental brushes.
- Replace your toothbrush every 2 to 3 months.
- Have regular dental check-ups so problems can be spotted early.
- Do not use mouthwash straight after brushing your teeth.
Common questions
How do I get rid of a dental abscess?
A dental abscess needs treatment by a dentist — it won't clear on its own. Treatment usually involves draining the pus, removing the infection, and sometimes a root canal or tooth extraction. Antibiotics may be prescribed if the infection is spreading.
Can a dental abscess be an emergency?
Yes. Call 111 or go to A&E if swelling is spreading to your face, neck, or eye; you have difficulty breathing or swallowing; or you feel very unwell with a high fever. Rarely, dental infections can spread and become life-threatening.
How can I ease dental abscess pain before seeing a dentist?
Take paracetamol or ibuprofen at the recommended dose. Rinse with warm salty water, avoid very hot or cold foods, and eat soft foods on the other side of your mouth. Don't use heat on the outside of your face — this can make swelling worse.
