Root canal treatment is one of the most effective ways to save a tooth that has become badly infected or damaged. Every year, thousands of patients across the UK undergo this procedure to relieve pain and preserve their natural smile. But one question comes up almost every time — do I also need a crown afterwards, and what will the total cost be?
Understanding the cost of root canal and crown UK patients typically face is important for planning your treatment. The combined expense covers two distinct procedures — the root canal itself and the protective restoration that follows. Both play a role in ensuring the treated tooth lasts as long as possible.
This guide explains what happens during treatment, when a crown is truly necessary, and how much you can expect to pay at each stage. If you are currently experiencing tooth pain or signs of infection, same-day appointments are available through our emergency dental treatment services in London.

What Is a Root Canal Treatment?
A root canal treatment removes infected or inflamed tissue from inside a tooth. The dentist cleans the internal canals, disinfects them, and fills them with a biocompatible material. The procedure aims to save the natural tooth, relieve pain, and help prevent the infection from spreading to surrounding bone and tissue. Treatment is carried out under local anaesthetic and is typically painless.
The dental pulp — the soft tissue containing nerves and blood vessels inside your tooth — can become infected through deep decay, cracks, or repeated dental procedures on the same tooth. Once the pulp is infected, it cannot heal on its own. Without treatment, the infection is likely to worsen. Pain may increase. An abscess may form at the root tip.
Root canal therapy removes only the damaged tissue while keeping the outer structure of the tooth intact. This is why it remains the preferred approach over extraction whenever possible. Keeping your natural tooth can help preserve your bite, maintain jawbone density, and may avoid the need for implants or bridges.

Book an appointment with our team →The root treatment cost varies depending on the tooth and the complexity of the canal system. Front teeth with a single canal are typically quicker to treat. Molars with three or four canals take longer and require more precision. The price of RCT reflects this difference. Many patients wonder how much does a root canal cost before committing to treatment — and the answer depends on several factors we cover below.

Why Is a Crown Often Needed After a Root Canal?
After root canal therapy, the treated tooth loses its internal blood supply. Over time, this makes the tooth more brittle and prone to fracture. A crown acts as a protective shell, covering the entire visible portion of the tooth and holding it together under the forces of biting and chewing.
Think of it this way. The root treatment and crown work together as a team. The root canal aims to save the tooth from infection. The crown helps protect it from fracturing afterwards. Without that protective layer, a treated tooth — especially one that was already weakened by decay or a large filling — is at significantly higher risk of cracking.
Molars bear the greatest chewing load. They grind food with considerable force every single day. This is why RCT molar teeth almost always require a crown as part of the full restoration. The root canal and crown cost reflects both procedures working together to deliver a lasting result.
For teeth that have lost substantial structure, your dentist may also place a post inside the root canal before fitting the crown. This provides additional internal support. Our guide on broken tooth repair treatment options explains how damaged teeth are restored.
Cost of Root Canal and Crown UK – Full Price Breakdown
The cost of root canal and crown UK patients pay depends on the tooth position, the type of crown material chosen, and the practice location. Below is a general guide to private treatment prices in the UK. All figures are approximate and may vary depending on individual circumstances.

Cost of Dental Crown and Root Canal – What Affects the Price?
Several factors influence the cost of dental crown and root canal treatment. Understanding these helps you anticipate the final bill and make informed choices about your care.
Tooth location. Front teeth have fewer canals and are simpler to treat. Molars at the back of the mouth have complex root systems with multiple curved canals. The additional clinical time and skill required for molars is reflected in a higher root canal price.
Crown material. All-ceramic and zirconia crowns offer the best aesthetics and durability but sit at the higher end of the price range. Porcelain-fused-to-metal crowns are a more affordable alternative that still provides good strength and a natural appearance.
Complexity of the infection. A straightforward infection with clear, accessible canals is quicker to treat than a complex case involving calcified canals, unusual root anatomy, or a large abscess. Complex cases may require additional appointments or specialist referral, which increases the root treatment cost.
Clinic location. Practices in central London typically have higher overheads than those in other parts of the UK. However, London practices often offer same-day availability, advanced equipment, and experienced clinicians. The root canal price reflects the level of service and convenience provided.
Additional procedures. Some teeth require a post and core build-up before the crown can be placed. Others may need retreatment if a previous root canal has failed. These additions increase the overall cost but are essential for a successful long-term outcome.
Root Canal and Capping Cost – Is a Crown Always Required?
Not every tooth that undergoes root canal treatment needs a crown. In certain situations, a well-placed filling can provide adequate protection. The root canal and capping cost is lower when a filling is used instead of a full crown, but this option is only suitable for specific cases.
Front teeth with minimal damage. If a front tooth has had root canal treatment but retains most of its natural structure, a composite filling to seal the access hole may be sufficient. Front teeth experience less biting force than back teeth, which reduces the fracture risk.
Teeth with small access cavities. When the decay that led to the root canal was small and the access opening is conservative, the remaining tooth walls may be strong enough to support a filling alone. Your dentist will assess the structural integrity before recommending the best option.
Temporary protection. In some cases, a filling is placed as a temporary measure while the patient decides on or saves for a crown. This is acceptable as a short-term solution, but a permanent crown should ideally be fitted within a few months to reduce the risk of fracture.
The root canal and crown cost is higher than a filling, but for most posterior teeth, the investment in a crown is worthwhile. It significantly extends the lifespan of the treated tooth. Our guide on root canal vs extraction — saving a tooth explores when preserving a tooth makes the most sense.
Root Canal Treatment for Molars
Molars are the large teeth at the back of the mouth. They have broad chewing surfaces and multiple roots — usually two or three — each containing one or more canals. Treating RCT molar teeth is more involved than treating front teeth because every canal must be located, cleaned, and sealed.
The chewing forces on molars are substantial. Each time you eat, your back teeth absorb considerable pressure. A molar that has been hollowed out during root canal treatment has thinner walls and reduced structural support. Without a crown, the risk of a vertical fracture is high — and a vertically fractured tooth usually cannot be saved.
This is why almost every molar that receives root treatment and crown restoration benefits from the full coverage a crown provides. The crown distributes the biting forces evenly across the entire tooth, protecting the weakened walls from cracking.
Some molars also require a post and core. This involves placing a small post inside one of the root canals to provide an anchor for the crown. The core build-up replaces the missing tooth structure and creates a stable foundation.
For patients concerned about molar fractures, our article on understanding tooth fractures and treatment options provides detailed guidance.
What Happens If You Skip the Crown?
Choosing not to have a crown after root canal treatment is a risk. The tooth may feel fine initially — the pain is gone, the infection is cleared, and the filling seems solid. But the underlying vulnerability remains.
Tooth fracture. Without the reinforcement of a crown, the treated tooth is exposed to normal chewing forces without adequate protection. Over weeks, months, or years, micro-cracks can develop. A sudden bite on something hard — a nut, a seed, even crusty bread — can cause the tooth to split. A fractured tooth may need extraction.
Reinfection. The temporary filling or composite used to seal the access hole may not provide a perfect long-term seal. Bacteria can eventually leak past the filling, re-entering the canal system and causing a new infection. This can lead to an abscess, pain, and the need for retreatment or extraction.
Tooth loss. The combination of structural weakness and potential reinfection means that an uncrowned root-treated tooth has a significantly shorter lifespan. Losing the tooth creates a gap that affects your bite, your appearance, and the health of neighbouring teeth.
If you notice signs that a treated tooth may be developing problems — persistent sensitivity, swelling, or discomfort — seek advice promptly.

Root Canal Near Me – When to Seek Urgent Treatment
Some dental situations cannot wait. If you are searching for a root canal near me because you are in pain right now, it is important to recognise the symptoms that indicate urgent treatment is needed.
Severe or persistent toothache. A deep, throbbing pain that does not respond to over-the-counter painkillers often indicates that the nerve inside the tooth is inflamed or dying. This type of pain typically worsens at night and can radiate to the jaw, ear, or temple.
Swelling in the face or gum. Visible swelling near a painful tooth suggests an abscess may be forming. The area may feel warm and tender to the touch. Facial swelling should always be assessed promptly.
Prolonged sensitivity to hot or cold. If a tooth remains painful for minutes after exposure to hot or cold food and drink, the pulp may be irreversibly damaged. This lingering sensitivity is different from the brief twinge a healthy tooth might produce.
Pain when biting or pressing on a tooth. Discomfort when chewing or when pressing on a specific tooth can indicate infection at the root tip or a crack in the tooth structure. Both require professional assessment.
Darkening of a tooth. A tooth that has changed colour — becoming grey or dark yellow — may have a dying nerve. This can occur weeks or months after trauma and often requires root canal treatment to prevent further complications.
If you are experiencing any of these symptoms, prompt treatment can make the difference between saving and losing the tooth. Our walk-in dentist in London service accepts patients without registration. Weekend emergency dentist appointments and out-of-hours dentist London availability ensure you can be seen when you need help most.
Preventing Future Root Canal Treatment
Most root canal treatments become necessary because a cavity was not treated early enough. What starts as a small area of decay gradually works its way through the enamel, through the dentine, and eventually reaches the pulp. At that point, root canal treatment is the only way to save the tooth.
Preventing this progression is far simpler and far less expensive than treating it.
Treat cavities early. A small filling costs a fraction of the price of a root canal and crown. If your dentist identifies early decay, addressing it promptly stops the problem before it reaches the nerve.
Attend regular dental check-ups. Routine examinations allow your dentist to spot developing problems — small cavities, hairline cracks, early signs of gum disease — before they escalate. Catching issues early almost always means simpler, cheaper treatment.
Do not ignore tooth pain. Pain is your body's way of telling you something is wrong. A twinge that disappears might be nothing. But persistent or worsening pain needs professional assessment. Delaying treatment rarely makes the problem go away — it usually makes it worse and more costly to fix.
Protect your teeth. If you grind your teeth at night, a custom-made night guard can prevent the excessive wear and fractures that sometimes lead to root canal treatment. If you play contact sports, a mouthguard is essential.

Frequently Asked Questions
How much is a root canal and crown in the UK?
The combined cost of root canal treatment and a dental crown in the UK typically ranges from £800 to £2,000 at a private practice. The exact price depends on the tooth being treated, the number of root canals, and the type of crown material selected.
Front teeth with a single canal sit at the lower end of the range. Molars with multiple complex canals sit at the higher end. The crown material also affects the price — zirconia and all-ceramic crowns tend to cost more than porcelain-fused-to-metal options.
Your dentist will provide a clear treatment plan with itemised costs before any work begins, so you know what to expect.
What is the cost of root canal treatment UK?
The cost of root canal treatment in the UK ranges from approximately £350 to £1,000 at a private practice. The price varies based on the tooth type and the complexity of the canal system.
A front tooth with one canal typically costs between £350 and £600. A premolar with one or two canals falls between £450 and £750. Molar root canal treatment — the most complex — usually costs between £600 and £1,000.
NHS root canal treatment is available under Band 2 at a fixed charge, but availability and waiting times vary across the country.
Is a crown always needed after root canal?
A crown is not always needed, but it is recommended in most cases — particularly for back teeth. After root canal treatment, the tooth loses its internal blood supply and becomes more brittle over time. A crown protects the tooth from fracture during normal biting and chewing.
Front teeth with minimal structural loss may be adequately protected with a well-placed composite filling. However, for premolars and molars, the forces involved in chewing make a crown the safer and more durable option.
Your dentist will assess the remaining tooth structure and advise whether a crown is necessary or whether a filling is a suitable alternative.
What is the price of RCT for molar teeth?
Root canal treatment for a molar typically costs between £600 and £1,000 at a private dental practice in the UK. Molars are more expensive to treat because they usually have three or four root canals, each of which must be individually located, cleaned, shaped, and sealed.
The treatment takes longer and requires greater precision. When a crown is added — which is almost always recommended for molars — the total restoration cost for a molar ranges from approximately £1,100 to £2,000.
Can I delay getting a crown after root canal?
A short delay of a few weeks is generally acceptable, provided the temporary filling remains intact. However, leaving a root-treated tooth without a permanent crown for an extended period increases the risk of fracture and reinfection.
Without a crown, the tooth is vulnerable to cracking under normal chewing forces. If the tooth fractures vertically, it may not be salvageable and extraction could be required. Reinfection can also occur if bacteria leak past the temporary filling.
The recommended approach is to have the crown fitted within four to six weeks of completing root canal treatment. If you are unsure whether a treated tooth needs attention, our guide on 10 warning signs you need an emergency dentist immediately can help you decide when to seek care.
