Which tooth
Canal count sets the fee. Front teeth have one, premolars one or two, molars three or four, and each canal has to be found, measured, cleaned and filled.

Root canal cost in London: priced by the tooth, and why the crown belongs in the sum
Root canal fees follow the anatomy. A front tooth has one canal and takes about an hour, so it costs least; a molar has three or four canals, takes ninety minutes or more and sometimes two visits, so it costs most. At Wimpole Street those figures are £695, £795 for a premolar and £895 for a molar, with retreatment of a previously root-filled tooth from £1,200. The number that patients most often leave out of their budgeting is the crown that a back tooth needs afterwards, from £995, without which the treatment is at real risk of being wasted. This guide lists the fees, explains the additions, and sets root treatment against the cost of the alternative, which is extraction followed by something to fill the gap.
Typical range
£695 – £895
For a first-time root canal treatment. Retreatment from £1,200. A crown on a treated back tooth is from £995 and priced separately.

Variables
What changes the price
First treatment or retreatment
Removing an old root filling and any post before re-treating takes far longer and carries somewhat lower odds, which is why retreatment is from £1,200.
Number of visits
Heavily infected teeth may need an antibacterial dressing and a second appointment. The fee is for the tooth, not per visit, so a two-visit molar costs the same £895.
The restoration afterwards
A front tooth often manages with the bonded filling included in the fee. Back teeth need a crown from £995, and a badly broken-down tooth may need a core or post first.
Emergency timing
If you arrive in pain, the first visit may be an emergency assessment and dressing to settle things, with the definitive treatment booked shortly after. The assessment is £30 for new patients.
Complexity
Unusually curved or calcified canals occasionally warrant referral to an endodontic specialist, whose fees are higher. We tell you at the assessment if we think that is the wiser route.

What's included, and what isn't
Included in the fee
- Local anaesthetic and rubber dam isolation.
- Working radiographs to measure and confirm the canals.
- Cleaning, disinfection and filling of every canal in the tooth.
- Any antibacterial dressing and the second visit if one is needed.
- The bonded filling sealing the access cavity.
- A review of symptoms at your next examination.
Charged separately
- The £30 assessment (usual fee £95) and diagnostic radiographs at £20 each.
- A crown from £995 on molars and premolars, and any core or post required.
- Antibiotics or prescription analgesics, where clinically indicated.
- Specialist endodontic referral fees where a case is beyond general practice.
- Surgery at the root tip if infection persists after treatment.
- Internal whitening of a front tooth that darkens later.
Paying
Spreading the cost
Root canal treatment plus a crown on a molar comes to £1,890, and that figure can be spread. Interest-free instalments over up to twelve months are available on eligible plans, subject to status, which would be £157.50 a month with nothing added. The root treatment alone at £895 would be just under £75 a month.
Where finance is not used, the root canal fee is paid at the visit it is completed and the crown in two stages, at preparation and at fitting.

Context
How we compare
Root canal fees in London vary from about £400 to well over £1,200 for a molar, with specialist endodontists at the upper end. Very low quotes sometimes exclude radiographs or the final filling, or reflect treatment without magnification or a rubber dam, both of which affect outcomes.
Our £695 to £895 range is the same across all three Medical & Dental clinics. The fairer comparison is with the alternative: extraction from £250 followed by an implant with crown at £2,950, a bridge at £2,985 or a partial denture from £795. Keeping the tooth, even with a £995 crown on top, is usually the less expensive path over the years as well as the better one for the neighbouring teeth.
FAQ
Questions about cost
More canals, more complex anatomy and more time. A molar takes ninety minutes or more against an hour for an incisor, and sometimes a second visit.
On a back tooth, yes, and we would rather you budget for it from the start. Root-treated molars without a crown fracture at a high rate; the crown is what makes the treatment last.
On the day, yes. Over the years, rarely, because the gap will want filling: an implant, a bridge or a denture, each costing more than the root treatment and crown. A gap left open also lets the neighbours drift.
Retreatment from £1,200 is the usual next step and succeeds in most cases. Where a tooth cannot be saved, extraction and replacement are discussed. Success rates for first treatments are high but not universal.
No. The fee is per tooth. If a heavily infected molar needs a dressing and a second appointment, the price stays at £895.
Yes, interest-free over up to twelve months on eligible plans, subject to status. Medical and Dental Limited is a credit broker, not a lender, and terms apply.
No. These prices apply now at South Kensington and St Paul’s and will apply at Wimpole Street from 1 October 2026.
