Specialist Root Canal Treatment — London
At ClearCanal Dental, root canal treatment is the only thing we do. Every clinician on our team holds a postgraduate Masters or Fellowship in Endodontics from a UK university — meaning you receive genuine specialist care, not a procedure carried out by a general dentist between fillings and scale-and-polishes.
Root canal treatment (endodontic therapy) removes infected or damaged pulp tissue from inside the tooth, cleans and shapes the root canals, and seals them to prevent reinfection. In skilled hands, with adequate anaesthesia, the procedure is comfortable and in most cases is completed in a single visit.
Our Clinical Technology
- Carl Zeiss surgical operating microscopes — 25× magnification
- 3D Cone Beam CT (CBCT) scanning for complex anatomy
- Rotary nickel-titanium instrumentation for cleaner, faster results
- Electronic apex locators for precise measurement
- Rubber dam isolation — sterile, safe working environment
- Warm vertical condensation for hermetic root fillings
Specialist endodontists achieve significantly higher success rates than general dentists for complex cases — particularly re-treatment of failed root canals, calcified canals, and teeth requiring surgical endodontics.
Why London Patients Choose ClearCanal
From our GDC-registered specialist team to our same-day availability and advanced technology, here is what makes our London root canal clinic different.
Same-Day Appointments
Emergency root canal appointments available most days. Call before noon and we will do our utmost to see you the same day — no multi-week waits.
Surgical Microscope Care
We treat every root canal under a surgical operating microscope. This level of magnification — unavailable in most practices — is the single biggest factor in long-term success.
Pain-Free Guarantee
We use advanced local anaesthetic protocols including articaine and buffered anaesthesia. The overwhelming majority of our patients report no pain during treatment.
Transparent Pricing
Full written cost estimate before treatment begins. No hidden fees. 0% interest-free finance available over 6 or 12 months. We accept all major payment cards.
Postgraduate Specialists Only
Every clinician holds a UK postgraduate qualification in Endodontics. We do not employ general dentists to perform root canal treatment — ever.
Central London Location
Steps from Oxford Circus station. Accessible from every part of London in under 30 minutes by tube. Evening and Saturday appointments available every week.
Your Treatment Journey
We believe that informed patients are relaxed patients. Here is exactly what happens at each stage of your root canal treatment.
Digital periapical X-rays and, where indicated, 3D CBCT scanning to map root canal anatomy and confirm diagnosis before treatment begins.
The tooth and surrounding tissue are thoroughly anaesthetised. A rubber dam is placed to isolate the tooth, providing a clean, sterile operating field.
Under 25× surgical microscope magnification, infected pulp tissue is removed. Canals are cleaned, shaped, and disinfected with rotary instruments and irrigants.
Root canals are filled with biocompatible gutta-percha using warm vertical condensation. A definitive restoration — typically a crown — is placed to protect the tooth long-term.
Root Canal Treatment — Clinical Details
Everything you need to know about the procedure itself, recovery, and long-term outcomes.
Most root canal treatments take 60–90 minutes per appointment. Single-rooted teeth (incisors, canines) are often completed in one visit. Multi-rooted molars may require two appointments. Complex re-treatment cases may need longer.
We use articaine 4% with adrenaline as standard, which provides significantly deeper anaesthesia than the lignocaine used in most practices. For patients with anaesthetic difficulties, we offer intraligamentary and intraosseous injection techniques.
Most patients return to normal activities — including work — within 24 hours. Some mild soreness for 2–3 days is normal and responds to standard over-the-counter pain relief. Severe pain after root canal treatment is uncommon.
Root canal treatment by a specialist endodontist has a reported 10-year success rate of 85–97%. Success depends on the extent of pre-operative infection, quality of the root filling, and quality of the definitive restoration.
Root canal treatment at our London clinic ranges from £700 (anterior tooth, single canal) to £1,400 (upper molar, four canals). Re-treatment of failed root canals is priced individually. 0% finance available.
The only alternative to root canal treatment for an infected tooth is extraction. We always discuss both options honestly. Where the tooth can be saved, root canal treatment is almost always preferable to extraction.
Serving Patients Across London
Our Central London root canal clinic is located on Harley Street, W1 — the heart of London's specialist medical district. We treat patients from every postcode in London, as well as patients who travel from outside the capital for specialist endodontic care.
When you search for root canal treatment London, you will encounter a wide range of providers: NHS dental practices, high-street private clinics, and genuine specialist endodontic clinics. The difference matters. A specialist endodontic clinic will have dedicated microscopes, CBCT scanners, and clinicians who perform root canal treatment every single working day. A high-street practice will not.
Root Canal Treatment London — Costs & NHS
Private root canal treatment in London typically costs between £600 and £1,500. NHS root canal treatment is available at Band 2 (£73.50 in 2025) from general dental practices, but NHS access to specialist endodontists is severely limited — waiting times for NHS specialist referrals routinely exceed six months. If you are in pain, a private specialist appointment is often the fastest route to relief.

Root Canal FAQs — London
Detailed answers to the questions our London patients ask most often before, during, and after root canal treatment.
Root canal treatment performed under adequate local anaesthesia should not be painful. We use articaine 4% with adrenaline, which provides markedly deeper anaesthesia than standard lignocaine. Most patients tell us the procedure was far less uncomfortable than they expected — comparable to having a filling. Any post-operative soreness typically peaks at 24–48 hours and resolves within three days, responding well to ibuprofen and paracetamol.
The majority of our cases are completed in a single appointment of 60–90 minutes. More complex cases — including lower molars with curved canals, teeth with active abscesses requiring drainage, or re-treatment of previously treated teeth — may require two appointments. We will give you a realistic estimate at the outset, and we never extend treatment unnecessarily.
At ClearCanal Dental, root canal treatment starts from £700 for a single-canal anterior tooth and ranges up to £1,400 for a multi-canal upper molar. Re-treatment of a failed root canal is quoted individually following assessment. A full written estimate is provided before treatment begins. We offer 0% interest-free finance over 6 or 12 months, and accept all major credit and debit cards.
Specialist endodontic treatment has a reported 10-year survival rate of 85–97% in the published literature. Key factors influencing success include the degree of pre-operative infection, the quality of canal preparation and obturation, and the quality of the definitive restoration placed afterwards. We optimise all three. By contrast, root canal treatment performed without a microscope by a general dentist carries significantly lower success rates, particularly for complex cases.
An infected tooth pulp will not resolve without treatment. Without root canal treatment or extraction, the infection will spread through the apex of the root into the surrounding bone, potentially causing a periapical abscess, osteomyelitis, or — in rare cases — life-threatening systemic spread. Dental infections should always be treated promptly. If the tooth cannot be saved with root canal treatment, extraction is the appropriate alternative.
Root canal treatment is available on the NHS at Band 2 (£73.50 in 2025). However, NHS access to specialist endodontists in London is extremely limited — referral waiting times routinely exceed six months. NHS Band 2 treatment covers root canal treatment by a general dentist, without access to surgical microscopes, CBCT imaging, or the level of expertise available at a specialist clinic. For patients in pain or with complex cases, private specialist treatment is strongly recommended.
No referral is required. You can contact us directly by phone or email to arrange an initial consultation. Self-referred patients are warmly welcomed. If your own dentist has referred you, please bring any referral letters, clinical notes, or X-rays. We will provide your referring dentist with a full written treatment report on completion.
Call us immediately on 020 7946 0000. We reserve same-day emergency appointments daily. If you call before noon, we will do our best to see you the same day. Emergency appointments include a full clinical examination, digital X-rays, and — where clinically appropriate — immediate commencement of root canal treatment to drain the infection and provide relief. If we are unable to see you and your pain is severe, please attend your nearest A&E or NHS emergency dental service.
