What a Private Root Canal Really Costs in the UK (2026)
Last updated 29 September 2026
Root canal treatment is priced by which tooth is being treated, not as a flat fee, because a front tooth with one root canal is a much simpler job than a back molar with three or four.
Quick answer: based on 204 practices that publish a price on Keystone, root canal treatment costs from £150 to £1,500, with most practices charging £358 to £725. Front teeth sit at the lower end of that range and molars at the higher end.
What actually drives the price difference
- Which tooth. Front teeth usually have a single canal and are the cheapest to treat. Molars can have three or four canals and take longer, which pushes the price up.
- Straightforward vs complicated. A tooth with curved or narrow canals, or one being retreated after a previous root canal, takes more time than a routine case.
- Who carries it out. An endodontist, a specialist in root canal treatment, typically charges more than a general dentist, but may be the right choice for a difficult case.
- What happens afterwards. A tooth that's had root canal treatment often needs a crown to protect it, and that's almost always priced and billed separately.

When you're comparing quotes, check whether the price is for the root canal alone or includes the follow-up crown, since leaving that out is the most common way a quote looks cheaper than it turns out to be.

How much does a root canal cost in the UK?
Based on 204 practices that publish a price on Keystone, root canal treatment costs from £150 to £1,500, with most practices charging £358 to £725. Front teeth generally cost less than molars.
Why do molars cost more than front teeth for the same treatment?
Molars typically have more root canals, sometimes three or four compared to one in a front tooth, so the appointment takes longer and involves more work.
Do I need a crown after a root canal?
Often, yes, especially for a molar, since the tooth is more fragile afterwards and a crown protects it from cracking. This is usually quoted and charged as a separate treatment.
Is it cheaper to just have the tooth removed instead?
Extraction is usually cheaper than root canal treatment upfront, but it means losing the tooth, and replacing it later with an implant or bridge often costs more overall than saving it would have.
