Root Canal Cost UK | NHS vs Private Prices Explained
Dentologi editorial team · 23 October 2026
If your dentist has just told you a tooth needs a root canal, two worries usually arrive together: will it hurt, and what will it cost? The root canal cost UK patients face can range from a fixed NHS charge of under £80 to well over £1,500 privately once a crown is added, and that gap can feel confusing when you are already dealing with toothache.
This guide explains NHS charges in England, Wales and Scotland, typical private and specialist fees by tooth, why the crown afterwards often costs as much as the root canal itself, and how root canal treatment compares with taking the tooth out or replacing it with an implant. We also cover risks, what your dentist checks first and how to get a clear quote. At Dentologi we do not treat patients; we help you find NHS and private practices near you, so you can compare your options with the facts in hand.

How much does a root canal cost in the UK?
Root canal treatment (also called endodontic treatment) removes infected or inflamed pulp, the soft tissue containing the nerve and blood supply, from inside a tooth. The canals are then cleaned, shaped, filled and sealed. According to the NHS, it is usually recommended when tooth pain is caused by infection, which can follow decay, gum disease, a cracked or broken tooth, or an abscess.
The price you pay depends mainly on three things: whether you are treated on the NHS or privately, which tooth needs treating, and who carries out the work (a general dentist or a specialist endodontist).
Root canal cost UK on the NHS
NHS dentistry uses set charges, and the rules differ across the four nations.
- England: root canal treatment sits in Band 2, which costs £76.60 from 1 April 2026, according to the NHS Business Services Authority. Band 2 also covers fillings and extractions, and you pay one charge per course of treatment, however many visits it takes.
- Wales: Wales has moved to item-based charges. Which? reports that a root canal now costs £182.72 under the new Welsh system.
- Scotland: you pay 80% of the cost of each course of NHS treatment, up to a maximum of £384, unless you qualify for free care.
- Northern Ireland: charges follow their own fee scale, so ask your practice for a written estimate before treatment starts.
Some people pay nothing at all. In England you are usually entitled to free NHS dental treatment if, at the start of treatment, you are under 18, under 19 and in full-time education, pregnant or have had a baby in the last 12 months, or receive certain benefits. The NHSBSA free treatment checker explains the rules, and the HC2 certificate can help if you are on a low income.
The catch with NHS root canal treatment is access rather than price. Many practices have limited NHS capacity, and complex cases may be referred to a hospital or specialist service with a waiting list. Our guide on how to find an NHS dentist covers practical ways to get seen.
Private root canal cost UK by tooth type
Privately, fees rise with the number of canals. A front tooth usually has one canal, a premolar one or two, and a molar three or four, sometimes with curved or very narrow canals that take longer to find and clean. The ranges below are typical of UK practice price lists we have seen. One London practice, Whites Dental, lists around £400 to £455 for front teeth, £500 to £565 for premolars and £600 to £695 for molars, with specialist care from about £800.
| Tooth | General dentist (private) | Specialist endodontist |
|---|---|---|
| Front tooth (incisor or canine) | £300 to £600 | £600 to £1,000 |
| Premolar | £400 to £700 | £700 to £1,200 |
| Molar | £500 to £1,000 | £800 to £1,500+ |
| Re-treatment of an old root filling | Often referred on | £900 to £1,800+ |
These are guide ranges only. Prices vary by practice and region, with London and the South East usually at the higher end, and a written quote after an examination and X-ray is the only figure you should rely on.
What pushes the price up
- Re-treatment: undoing an old root filling is slower and harder than a first treatment.
- Difficult anatomy: curved, blocked or extra canals add time, and sometimes a referral.
- Equipment: specialists often use an operating microscope and 3D cone beam CT scans, which can improve precision but add cost.
- Extra visits and X-rays: check whether these are included in the quote or charged separately.
- The final restoration: a filling, core build-up, post or crown is often priced on top.
The crown: the cost people forget
A root-treated back tooth is more brittle than a healthy one, because a large part of its structure has been removed to reach the canals. For that reason, dentists often recommend a crown, a cap that covers the whole tooth, on molars and premolars after treatment. The NHS notes that a crown may be needed if the tooth was badly infected.
This matters for outcomes as well as cost. A large UK study led by researchers at UCL and the Eastman Dental Institute (Ng, Mann and Gulabivala, International Endodontic Journal, 2011) found around 95% of teeth survived four years after root canal treatment, and a permanent cast restoration such as a crown, rather than a temporary one, was one of the factors linked to better tooth survival. Patient guidance from Leeds Teaching Hospitals NHS Trust also warns that delaying the final restoration significantly raises the risk of failure or fracture.
Crown prices on the NHS and privately
- NHS in England: crowns are Band 3 at £332.10. If the crown is part of the same course of treatment as the root canal, you pay the Band 3 charge once, not Band 2 plus Band 3.
- Private: crowns usually cost £500 to £1,000 or more, depending on the material (metal, porcelain bonded to metal, or all-ceramic options such as zirconia or Emax) and the practice. A core build-up or post may add £100 to £300.
So a private molar root canal plus crown can realistically total £1,200 to £2,000, and more with a specialist. Ask for the full treatment plan, including the crown, before you agree to start.
Root canal, extraction or implant?
The main alternative to a root canal is taking the tooth out. Extraction is cheaper on the day, but a gap can lead to neighbouring teeth drifting, changes to your bite and, for a visible tooth, a cosmetic concern. Replacing the tooth later with an implant, bridge or denture usually costs far more than saving it. Here is how the options compare.
| Option | Typical private cost | Things to weigh |
|---|---|---|
| Root canal plus crown (molar) | £1,200 to £2,000+ | Keeps your natural tooth; 2 or more visits plus crown appointments |
| Extraction only | £100 to £300 (Band 2 on the NHS) | Quick and cheap, but leaves a gap that may need filling later |
| Extraction plus implant | £2,000 to £3,500+ | Fixed and long lasting; surgery and several months of healing; rarely available on the NHS |
| Extraction plus bridge | £1,000 to £2,500+ | No surgery, but neighbouring teeth are usually trimmed to support it |
| Extraction plus partial denture | £400 to £1,500 | Lower cost and removable; some people find it less comfortable |
Prices vary by practice and region. Our guide to dental implant costs in the UK explains implant pricing and NHS rules in more detail.
Saving the tooth is not always the right answer. If there is too little tooth left to restore, a deep crack runs down the root, or the gum and bone support is poor, your dentist may advise that extraction gives a more predictable result.
What to know before you start
Only a dentist or specialist endodontist can decide whether root canal treatment is right for your tooth. The points below will help you understand their advice and ask the right questions.
Who root canal treatment suits
- People with a tooth that is infected or has inflamed pulp, often shown by lingering pain with hot or cold, pain on biting, swelling or a gum boil.
- Teeth with enough healthy structure left to be restored with a filling or crown.
- Teeth with healthy gum and bone support around them.
- Patients who want to keep a natural tooth and can attend more than one appointment.
What the dentist checks first
- A full check-up: your symptoms, medical history and the tooth itself, including tests of how it responds to cold or tapping.
- X-rays: to see the shape and number of roots and any infection at the root tip. Complex cases may need a 3D scan.
- Your gums: gum disease around the tooth can affect whether it is worth saving.
- Cracks and remaining tooth: whether the tooth can be sealed and restored afterwards.
Side effects, risks and contraindications
The NHS says it usually takes 2 or more appointments, each lasting 1 to 2 hours or sometimes longer, and that some swelling and soreness should improve within a couple of weeks. Paracetamol or ibuprofen usually help. Leeds Teaching Hospitals lists the main risks as:
- Flare-ups: about 1 to 5% of people get increasing pain or swelling a few days later.
- Instrument fracture: a small file can break inside a canal.
- Perforation: an unintended opening through the side of a root.
- Incomplete healing: healing can take from six months to several years, and some teeth still fail.
- Tooth fracture: a higher risk afterwards, especially without a crown.
Success rates are generally good. The same trust quotes about 96% where there is no inflammation at the root tip and about 85% where there is, with re-treatment at roughly 40 to 80% depending on the original problem. No dentist can guarantee an outcome, because healing depends on your body clearing the infection.
A root canal may not be suitable if the tooth cannot be restored, has a vertical root fracture or has very poor support. Tell your dentist about conditions such as diabetes and medicines such as steroids, since the 2011 UCL study linked both with lower tooth survival.
Treatment steps and getting a fair quote
What happens during treatment
You stay awake but numb under local anaesthetic. The dentist isolates the tooth, often with a thin rubber sheet called a dam, makes a small opening, removes the infected pulp, drains any abscess, and cleans and shapes the canals. A temporary filling may be placed between visits. Once the tooth has settled, the canals are filled and sealed, and the tooth is restored with a filling or crown.
Five steps to a fair root canal quote
- Get the tooth examined and X-rayed. A price given over the phone cannot account for the number of canals or hidden infection.
- Ask for an itemised written plan. It should list the root canal, X-rays, review visits, core build-up and crown separately, with what happens if extra visits are needed.
- Ask whether NHS treatment is available. If the practice offers NHS care and you are eligible, the Band 2 or Band 3 charge covers the whole course.
- Ask who will do it and about referral. For a molar, a re-treatment or a tooth with difficult canals, ask whether a specialist would improve your chances. You can check a specialist title on the General Dental Council specialist lists.
- Compare the alternative honestly. Ask for the cost and likely outcome of extraction and replacement too, so you are comparing the full picture, not just today's price.

Ways to pay for private root canal treatment
- Pay as you go: you pay the practice directly, often in stages as treatment progresses.
- Dental payment plans: monthly plans such as Denplan usually cover routine care and may include discounts on treatment, though root canal and crowns are not always fully included.
- Dental insurance: some policies pay towards treatment up to an annual limit, often with waiting periods and exclusions for problems that existed before you joined.
- Finance: many private practices offer monthly instalments, sometimes interest free over a short term. Check the APR and total amount repayable.

Mini FAQ
Is a root canal painful?
The treatment itself is done under local anaesthetic, so most people feel pressure rather than pain. The tooth and gum may feel sore for a few days afterwards, which over-the-counter painkillers usually manage. Often the toothache that led to treatment eases once the infection is removed.
Why does root canal cost in the UK vary so much?
The NHS charges a fixed band fee, while private fees reflect the tooth, the number of canals, the time needed, the clinician's training and equipment, and the local cost of running a practice. A specialist re-treating a molar with a microscope will cost far more than a general dentist treating a single-canal front tooth.
Can I just have the tooth out instead?
Yes, extraction is always an option, and on the NHS in England it falls in the same Band 2 as a root canal. The trade-off is the gap. Replacing a missing tooth later usually costs more than saving it, so ask your dentist to explain both paths.
How long does a root-treated tooth last?
Many last for years. Research from UCL found around 95% of root-treated teeth survived at least four years, and good outcomes are linked to a well-fitting permanent restoration, regular check-ups and good cleaning at home.
Conclusion
The root canal cost UK patients pay ranges from £76.60 on the NHS in England to £1,500 or more privately for a complex molar, and the crown that often follows can double the bill. The most useful step is a proper examination with X-rays and a written, itemised plan that includes the final restoration and the alternative of extraction. Weigh the full cost of saving the tooth against the full cost of replacing it, and let your dentist explain what is right for your mouth.
