Treating Dental Abscesses at Our W1 Clinic

A dental abscess is a bacterial infection producing a collection of pus in or around a tooth. It can trigger severe, throbbing pain, facial swelling and a general feeling of being unwell. Crucially, an abscess doesn't heal by itself, without dental treatment the infection persists and may spread further.

At Wimpole Street Medical & Dental in Marylebone, our emergency dentists are experienced in managing dental infections. We aim to see patients with suspected abscesses the same day, subject to availability, draining the swelling where appropriate and discussing options to resolve the underlying cause.

We're open 6 days a week, with late evenings on Tuesdays and Thursdays until 8pm and Saturday hours (10am–4pm). Our clinic at 22 Wimpole Street is a short walk from Bond Street and Oxford Circus stations.

How to Spot a Dental Abscess

Recognise any of these symptoms? We'd recommend arranging a prompt dental assessment.

Intense, throbbing pain that may radiate to the ear, jaw, or neck

Swelling of the face, cheek, or lymph nodes

A foul-tasting discharge if the abscess ruptures

Fever, feeling generally unwell, or malaise

Sensitivity to hot and cold that lingers

Pain that worsens when lying down or biting

Call 999 or go to A&E if: You have difficulty breathing or swallowing, swelling is spreading to the eye or throat, you have a high fever with chills, or the swelling is making it difficult to open your mouth fully. These may indicate a spreading infection that requires urgent medical intervention.

Types of Dental Abscess

Periapical Abscess

The most common type. Occurs at the tip of the tooth root, usually caused by untreated decay that has reached the pulp (nerve). Bacteria enter the dead or dying pulp and create an infection that spreads to the surrounding bone.

Typical treatment: Root canal treatment or extraction

Periodontal Abscess

Develops in the gum tissue, usually alongside an existing gum (periodontal) disease. A pocket forms between the tooth and gum where bacteria accumulate, leading to a localised infection.

Typical treatment: Drainage, deep cleaning, antibiotics

Gingival Abscess

A localised infection in the gum tissue that does not involve the tooth itself. Often caused by a foreign body (such as a popcorn kernel or toothbrush bristle) becoming trapped under the gum.

Typical treatment: Drainage and removal of foreign body

Our Approach to Abscess Treatment

Relieving your pain and controlling the infection come first. Treatment usually follows these steps.

Diagnosis

Clinical examination and digital X-rays to identify the source and extent of the infection. We assess whether the tooth can potentially be saved.

Pain Management

Local anaesthetic to numb the area. We take care to help ensure the anaesthesia is effective even in the presence of infection, where numbing can sometimes be more challenging.

Drainage

If a swelling is present, we may make a small incision to drain the pus, which often provides rapid relief from the pressure-related pain.

Definitive Treatment

Depending on the assessment, this may include root canal treatment to save the tooth, extraction if the tooth cannot be restored, or deep periodontal cleaning for gum abscesses.

Managing a Dental Abscess at Home

These measures may help manage your symptoms while you wait for your emergency appointment. They do not replace professional treatment.

  • Take anti-inflammatory painkillers such as Ibuprofen (if suitable for you) to help manage pain and swelling.
  • Rinse gently with warm salt water (half a teaspoon of salt in a glass of warm water) several times a day.
  • Avoid very hot or very cold food and drinks.
  • Do not attempt to drain the abscess yourself, this can spread the infection.
  • Keep your head elevated when sleeping to help reduce pressure.
  • Complete any prescribed course of antibiotics in full, even if symptoms improve.

Dental Abscess – Your Questions Answered

An abscess is a genuine infection that should be treated without delay. Most respond well to prompt dental care, but rarely the infection can spread to other areas of the head, neck or body. If you develop severe facial swelling, difficulty breathing or swallowing, a high fever, or swelling near the eye, call 999 or go to A&E straight away.
No, an abscess won’t resolve without professional treatment. Even if the pain eases after the abscess drains on its own, the underlying infection remains and usually returns, often more severely. Timely treatment deals with the source of the infection.
Antibiotics on their own don’t cure a dental abscess, the source must be treated dentally, through drainage, root canal treatment or extraction. Antibiotics may be prescribed alongside treatment if the infection is spreading, there is marked facial swelling, or you have a temperature. Our dentists assess whether they are clinically appropriate in your case.
Our emergency assessment for new patients is £30 (usual fee £95). Costs then depend on what’s required, drainage from £92.50, root canal from £347.50, extraction from £125. You receive a full written cost breakdown before treatment starts, so there are no surprises.
Often, yes, root canal treatment removes the infected pulp, cleans the canal system and seals the tooth. If the tooth is too badly damaged or the infection too extensive, extraction may be the better option. Our dentists will talk you through every viable choice.
