Root Canals

Root Canals

Modern, comfortable, effective

Root canal treatment has an undeserved reputation. The reality is, modern endodontic techniques are comfortable, highly effective and usually save a tooth that would otherwise need extraction. At Clarendons, we use magnification, rotary instruments and precise irrigation to clean, shape and seal the root canals — giving you back a pain-free tooth that can last for decades.

Severe toothache, sensitivity to hot and cold that won’t settle, a dull ache when biting, or swelling around a tooth — all classic signs you might need root canal treatment. The sooner we treat it, the better. In our calming clinic in Leeds city centre, with sedation available if needed, root canal treatment is far less dramatic than most patients expect.

What is a root canal?

Saving your tooth from the inside out

  • A root canal treats infection or damage in the pulp — the soft tissue inside the tooth containing nerves and blood vessels. When this pulp becomes inflamed or infected (through deep decay, trauma or a cracked tooth), it can cause severe pain and eventually an abscess.

  • Root canal treatment removes the damaged pulp, cleans and disinfects the inside of the root canals, and seals them with a biocompatible material. A crown is usually placed afterwards to protect the treated tooth.

Features and benefits

Modern care, lasting relief

  • Save your natural tooth

    Root canal treatment lets us keep your natural tooth — always preferable to extraction. A properly treated tooth can last a lifetime, preserving your bite and smile.

  • Modern, comfortable techniques

    Magnification, rotary instruments and precise anaesthesia mean modern root canals are far more comfortable than the procedures of decades past. Most patients report it’s no worse than a filling.

  • End the toothache

    Nothing compares to root canal pain — and nothing resolves it like proper treatment. Most patients feel dramatic relief within 24–48 hours of the procedure.

The Clarendon's Difference

Root canals that last. First time.

  • A good root canal is meticulous work. Every canal must be located, cleaned, shaped and sealed completely — or re-infection is a real risk. Our dentists use magnification loupes, rotary nickel-titanium instruments and advanced irrigation protocols to ensure each canal is thoroughly disinfected. We follow up with a properly fitted crown to protect the tooth. Done right, the tooth can last for decades.

  • Our award-winning clinic in Leeds city centre makes what can feel like a daunting procedure surprisingly manageable. Local anaesthetic means no pain during treatment. Sedation is available for nervous patients. Treatment is usually completed in one or two visits. And transparent pricing with interest-free finance takes the stress out of the cost.

How much does a root canal cost?

Saving your tooth is always worth it

Root canal costs depend on which tooth is being treated — front teeth (single canal) are more affordable than back molars (three or four canals). A crown afterwards is usually recommended and priced separately. At your consultation, we’ll provide a full itemised quote. Interest-free finance available. And remember: saving a natural tooth is almost always cheaper than extraction plus replacement (implant or bridge).

FAQs

Still have questions about root canals?

Do I really need a crown after a root canal?

In most cases, yes — especially for back teeth. Root-canal-treated teeth are weaker than natural teeth and vulnerable to fracture under chewing forces. A crown reinforces the tooth and dramatically improves its long-term survival. Skipping the crown is a false economy that often leads to tooth loss.

How long does a root-canal-treated tooth last?

A properly treated, properly restored tooth can last a lifetime. Studies show 85–97% success rates over 8+ years. The key is a thorough cleaning of all canals and a good crown afterwards to protect against fracture. Regular check-ups let us monitor the tooth for any long-term issues.

How long does root canal treatment take?

Most root canals are completed in one visit of 60–90 minutes. More complex cases (usually back molars with curved canals) may need two appointments. We’ll let you know what to expect at your consultation based on X-rays of the tooth.

Does a root canal hurt?

No — the procedure itself is comfortable. Local anaesthetic numbs the tooth completely, so you won’t feel pain during treatment. Most patients say it feels no different to having a filling. The painful part is the infection before treatment — root canal therapy is what ends the pain, not causes it.
