Dental Abscess (Tooth Abscess)
A collection of pus caused by a bacterial infection in a tooth, gum or the supporting bone — needs prompt care.
Overview
A dental abscess forms when bacteria reach tissue inside or around a tooth and the body's immune response produces pus. It typically develops as a complication of untreated decay, a cracked tooth, a failed root canal or advanced gum disease.
Abscesses rarely settle on their own. The infection is walled off inside the jaw, so painkillers and over-the-counter remedies may briefly reduce discomfort but do not address the cause. Without treatment, an abscess can grow, spread into surrounding tissue, and in rare cases cause serious systemic infection.
Our team prioritises abscess appointments. Treatment focuses on draining the infection, managing the tooth — usually through root canal treatment or, where the tooth cannot be saved, extraction — and prescribing antibiotics only when clinically indicated.
Common symptoms
- Severe throbbing pain
- Facial or jaw swelling
- Bad taste in the mouth
- Tender, warm-feeling gum over the tooth
- Feeling generally unwell
- Difficulty chewing or swallowing
Common causes
- Untreated deep decay
- Cracked or broken tooth exposing the nerve
- Previous dental work that has failed
- Advanced gum disease with deep pockets
- Trauma to a tooth, even years earlier
Our approach
Urgent same-day assessment
We offer rapid assessment for suspected abscesses — clinical exam, digital X-rays and pulp testing to confirm the diagnosis and source.
Drainage and infection control
Where appropriate, we drain the abscess to relieve pressure and pain. Antibiotics are prescribed only when clinically necessary, in line with current guidance.
Definitive treatment planning
Once the acute infection is controlled, we plan the definitive treatment — typically root canal therapy or, if the tooth cannot be saved, extraction and replacement options such as an implant or bridge.
What you can do at home
Practical pointers — not a replacement for clinical assessment.
- Seek professional care promptly — do not wait
- Rinse gently with warm salt water
- Take pain relief as directed
- Avoid heat on the face, as this can worsen swelling
- Attend A&E if swelling affects breathing or swallowing
