The 2026 Guide to Root Canal Treatment Cost in London: Is Private Care Really More Expensive?

If you have been told you need a root canal, one of the first questions you are likely to ask is: how much will it cost? It is a perfectly reasonable concern — and one that deserves a transparent, straightforward answer rather than vague estimates or hidden fees.

There is also a common assumption that private dental care is automatically expensive and that patients are always better off seeking treatment through the NHS. While NHS dentistry provides essential care, the reality of root canal treatment cost in London is more nuanced than a simple public-versus-private comparison suggests.

This guide provides a clear breakdown of what root canal treatment costs at our practice in 2026, explains why pricing varies by tooth type, and explores the finance options available. All prices quoted are those published on our service page at the time of writing. Final treatment costs are confirmed following a personalised clinical assessment.

The cost of root canal treatment depends primarily on which tooth needs treating and the complexity of the case. Here is our published pricing structure:

All member prices reflect 50% off standard rates. Membership costs £20 per month. Prices shown are those published on our root canal service page at the time of writing. Final treatment costs are confirmed following a personalised clinical assessment.

Why Does the Cost Vary by Tooth Type?

If you have looked at the pricing table above, you will notice that a front tooth root canal costs less than a molar root canal. This is not arbitrary — it reflects genuine differences in clinical complexity.

• Number of canals — front teeth typically have one canal, while molars have three or four. Each canal must be individually cleaned, shaped, and filled
• Treatment time — a single-canal incisor may take 45 minutes, while a multi-canal molar can take 90 minutes or longer
• Technical complexity — molar canals are often curved, narrow, or calcified, requiring more advanced instrumentation and greater clinical skill
• Imaging requirements — complex cases may benefit from additional imaging such as CBCT scans to map the root anatomy before treatment begins
• Retreatment complexity — if a previous root canal has failed, removing the old filling material and re-treating the canals adds both time and difficulty

Understanding why the cost varies helps frame the pricing in context. A molar root canal cost is higher because it genuinely requires more time, skill, and materials — not because of arbitrary pricing decisions.

Do You Need a Crown After a Root Canal?

In most cases, yes — particularly for back teeth. After root canal treatment, the tooth no longer has a living blood supply, which can make it more brittle over time. A dental crown provides a protective cap that reinforces the tooth and helps prevent fracture.

When budgeting for root canal treatment, the cost of root canal and crown together represents the full investment. For example, a member receiving a front tooth root canal (from £347.50) with a porcelain crown (from £497.50) would be looking at a combined starting cost from £845. For molars, the combined starting member cost would be from £945.

Private Dental Costs London — What Are You Paying For?

Private dental costs in London understandably attract scrutiny, and patients have every right to understand what they are paying for. The difference between NHS and private root canal treatment is not simply about the procedure itself — it reflects differences in the overall care experience.

• Longer appointment times — private appointments are typically longer, allowing the clinician to work without time pressure and giving you the opportunity to ask questions
• Advanced diagnostic tools — digital X-rays, CBCT imaging, and dental microscopes may be available to support complex treatment
• Continuity of care — you are more likely to see the same clinician throughout your treatment, which supports better communication and treatment planning
• Comfort-focused environment — from the waiting area to the treatment room, the clinical setting is designed with patient comfort in mind
• Flexible scheduling — evening and weekend appointments may be available to fit around your life

This is not to criticise NHS dentistry, which provides essential care for millions of patients. However, patients comparing costs should consider the full picture of what each option includes. The cost of private root canal treatment reflects the time, expertise, technology, and environment provided.

Is Private Root Canal Treatment Really More Expensive?

The upfront fee for private root canal treatment is typically higher than an NHS Band 2 charge. That is straightforward and transparent. However, when evaluating cost, a few additional factors are worth considering:

• Waiting times — NHS dental waiting lists for non-emergency treatment can be lengthy in London. Private care typically offers earlier access, which may be important when you are in pain or at risk of the tooth deteriorating further
• Predictability — private treatment planning tends to be more detailed, with a clear timeline and dedicated appointments rather than treatment fitted into shorter slots
• Long-term tooth preservation — if thorough root canal treatment avoids the need for extraction and subsequent replacement, the long-term financial outcome may be favourable
• Access to specialists — if your case is complex, private practices may be able to refer to or work alongside endodontists more readily

The question is not simply “which costs less today?” but “which option provides the best clinical outcome and long-term value for my situation?” Both NHS and private care have their place, and neither is universally better for every patient.

Can You Spread the Cost? Understanding Finance Options

We understand that root canal treatment — particularly when a crown is also needed — represents a meaningful financial commitment. That is why we offer structured payment options to help make treatment more accessible.

Finance is provided by Tabeo Finance Limited. Medical and Dental Limited (FCA number: 1047835) is acting as a credit broker, not a lender. All finance is subject to status, affordability checks, and terms and conditions. Your dentist and the practice team can discuss which option works best for your situation.

Root Canal vs Extraction — The Financial Comparison

One of the most common cost-related questions patients ask is whether extraction might be the cheaper option. In terms of the day-of fee, it usually is. But the financial picture changes when you factor in what comes after.

If an extracted tooth is replaced with a dental implant, the total cost typically includes the extraction itself, any bone grafting required, the implant placement, a healing period, and finally the abutment and crown. The combined investment is considerably more than root canal treatment with a crown.

This is not to suggest that extraction is always the wrong choice — there are clinical situations where it is the most appropriate option. But when a tooth can be predictably saved, root canal treatment is generally the more cost-effective long-term pathway.

When Should You Book a Consultation?

If you are experiencing any of the following, it may be appropriate to arrange an assessment to determine whether root canal treatment is needed:

• A persistent, throbbing toothache that may worsen at night or when lying down
• Lingering sensitivity to hot or cold that continues long after the stimulus is removed
• Swelling in the gum near a specific tooth, or facial swelling
• A darkening or discoloured tooth, which may indicate nerve damage
• Pain when biting or applying pressure to a tooth
• A recurring pimple or bump on the gum near a tooth

If you are in significant pain or have facial swelling, you may need to be seen urgently. Our practice offers same-day emergency dental appointments and can assess whether root canal treatment or an alternative approach is appropriate for your situation.
