Root canal treatment removes inflamed or infected tissue from inside a tooth, cleans the root canal system and seals it. It may help retain a tooth that would otherwise need extraction. Symptoms can include lingering pain, tenderness or swelling, although some teeth cause little discomfort. An examination and appropriate imaging are needed to establish the diagnosis and whether the tooth can be restored predictably.
Simple root canal treatment from £450 · Final fees depend on your individual plan.
A tooth with damaged pulp that still has enough structure to restore
Infection associated with deep decay, a crack or previous dental trauma
Patients wishing to explore retaining their natural tooth
Clear discussion of complexity, prognosis and specialist referral when appropriate
All treatment is subject to clinical assessment and individual suitability.
YOUR TREATMENT JOURNEY
What to expect.
01
Diagnose And Plan
The dentist asks about symptoms, examines the tooth and takes appropriate X-rays. We assess cracks, gum support and the final restoration needed. The plan explains the likely prognosis, number of appointments and whether the canals or previous treatment make referral advisable.
02
Clean The Canals
Local anaesthetic is used and a rubber dam normally isolates the tooth. The dentist accesses the pulp space, removes affected tissue and cleans the canals using instruments and disinfecting solutions. A temporary dressing may be placed between visits; completing the agreed course is important.
03
Seal And Restore
The canals are filled and the tooth sealed against contamination. A filling, onlay or crown is then planned according to the remaining tooth and bite. Follow-up checks assess symptoms and healing; the final protective restoration is part of the long-term plan, not an optional cosmetic extra.
Recovery And How Long It Lasts
Some tenderness can occur after treatment and should gradually settle. Contact the practice if pain worsens, swelling develops or the temporary filling is lost. A successfully treated and restored tooth can remain useful for years, but healing is not guaranteed. Reinfection, cracks and restoration failure can require further treatment. Regular reviews and cleaning remain necessary even though the original pulp has been removed.
Fees And Alternatives
The published private fees start at £450 for simple treatment, £650 for advanced treatment and £750 for retreatment. The assessment, final restoration and any referral costs should be clarified in your written estimate. Extraction is the main alternative when a tooth cannot be retained; replacement options may then include a bridge, denture or implant. Antibiotics alone do not remove the source inside an infected tooth. Ask about NHS options where clinically appropriate and available.
Local anaesthetic is used to control pain. Tell the dentist if you remain uncomfortable so they can reassess anaesthesia. A very inflamed tooth may need additional measures.
How many visits will I need?
The number varies with the tooth, infection and complexity. Your dentist will explain the anticipated schedule and any temporary restoration or dressing needed between appointments.
Will I always need a crown afterwards?
Not always, but weakened back teeth often need protective coverage. The decision depends on the remaining structure, cracks, existing restorations and forces during chewing.
Can a previously treated tooth be treated again?
Sometimes. Retreatment, root-end surgery or extraction may be considered after investigating the cause. Complex cases may be referred, and the costs and limitations will be explained.
Can I wait until the pain goes away?
Pain stopping does not prove the infection has resolved. Arrange assessment rather than waiting for another flare-up, especially if swelling, a bad taste or biting tenderness develops.
When is swelling an emergency?
Seek urgent dental advice for facial swelling. If swelling affects breathing or swallowing, call 999 or attend A&E immediately. NHS 111 can advise on urgent out-of-hours dental care.
