Root canal treatment at Clarendon Dental Spa in Leeds removes infected or inflamed pulp from inside a tooth, then cleans, disinfects and seals the canals to relieve pain and save your natural tooth, usually finished with a protective crown.
Root canal treatment at Clarendon is led by our endodontist, Dr Fadi Kreishan (MSc Endodontics, University of Manchester; MFDS Royal College of Surgeons), using microscope-enhanced technique and 3D imaging to give even complex or previously failed cases the best chance of success. Voted Dental Practice of the Year 2026 by real patients.
Root canal treatment removes infected or damaged pulp from inside a tooth, relieving pain and saving a tooth that might otherwise need extraction. Using modern rotary techniques and effective local anaesthesia, the procedure at our Leeds clinic is comfortable — most patients say it feels no different to having a filling.
Treatment is usually completed in one or two visits. Afterwards the tooth is sealed and often protected with a crown for long-term strength. Mild tenderness for a day or two is normal and settles with over-the-counter pain relief. We will give you clear aftercare guidance before you leave.

We’re committed to delivering exceptional endodontic care by investing in the best equipment available. From microscope-enhanced treatment to modern digital imaging and high-precision instruments, every tool is chosen to improve accuracy, comfort and long-term results — combining state-of-the-art technology with expert clinical skill.
A dental microscope gives the clinician exceptional magnification and lighting, revealing fine details inside the tooth that are otherwise impossible to see. Hidden canals, cracks and complex anatomy can be identified and treated with far greater accuracy.
Better visibility means more precise cleaning, shaping and sealing of the root canal system, reducing the risk of missed infection or complications. Microscope-assisted root canal treatment offers more predictable, longer-lasting outcomes.
Microscopes are especially valuable for retreatments, calcified canals, unusual anatomy or locating separated instruments — allowing specialist-level care even in the most difficult situations.
Having root canal treatment carried out by an endodontist — a dentist with advanced training focused on the inside of the tooth — offers clear advantages in precision, comfort and long-term success, especially in complex or previously failed cases. Our endodontist, Dr Fadi Kreishan, holds an MSc in Endodontics from the University of Manchester and MFDS from the Royal College of Surgeons, and focuses on preserving natural teeth through precise, evidence-based treatment.
Endodontists concentrate on diagnosing and treating problems inside the tooth. This focus allows confident management of complex anatomy, retreatments, and curved or calcified canals that general treatment may not routinely cover — leading to more predictable outcomes.
Using microscopes, ultrasonics and high-precision instruments allows areas to be seen and treated that are invisible without magnification — meaning more thorough cleaning, fewer missed canals and higher long-term success rates.
Teeth with previously failed root canals, unusual anatomy or persistent infection benefit greatly from advanced endodontic care, helping preserve natural teeth that might otherwise be lost.
When a tooth has been heavily broken down by decay or a large old filling, there may not be enough tooth left to hold a crown after root canal treatment. In these cases we place a post and core — a small support anchored inside the treated root that rebuilds the foundation, so a strong, natural-looking crown can be fitted on top.
It’s a key step in giving a root-treated tooth the best long-term chance, and we’ll explain clearly whether your tooth needs one before we begin. Rebuilding heavily compromised teeth is a core part of Dr Kreishan’s restorative and endodontic work.
Not every root canal succeeds first time — sometimes infection or discomfort returns months or years later. Endodontic re-treatment gives that tooth a second chance: we carefully remove the previous root filling, clean and disinfect the canal system under magnification, and re-seal it to modern standards.
With a dental microscope and 3D imaging we can often find missed or calcified canals that are a common cause of a failed first attempt — frequently saving a tooth that would otherwise be lost. If you’ve been told a previously treated tooth is failing, it’s well worth an assessment before considering extraction.
We welcome referrals from dentists across Leeds and West Yorkshire for complex root canal, re-treatment and difficult cases — calcified or curved canals, perforations, separated instruments and previously failed treatments. Cases are managed by our endodontist, Dr Fadi Kreishan (MSc Endodontics, Manchester), using microscope-enhanced treatment and 3D imaging.
Your patient is always returned to you for their final restoration and ongoing care, and you’ll receive a full written report covering the procedure, imaging and recommendations — so follow-up is seamless and you keep the relationship with your patient.

Fadi was an excellent dentist. I was extremely apprehensive prior to my root canal treatment. But he was super informative and reassuring throughout the procedure.
Rhiannon Thackwray
Having recently had a need for a root canal and crown I was referred to see Fadi, I have a fear of needles and the usual dislike of dental work, but Fadi was brilliant.
Sean Killen
I have had two complicated root canal treatments performed by Fadi within the last year - the most recent being this week. I am a very nervous patient and he was absolutely brilliant.
Helen Jackson
I feel very grateful that my teeth ended up in the capable hands of skilled dentist/endodontist Dr Fadi Kreishan at Clarendon Dental Spa. I had two procedures and both were painless and expertly done.
Marian Sommer
Dr Fadi Kreishan was an amazing dentist he treated my infected tooth with a root canal and saved my tooth. He is so professional and talented and that was from someone who has a severe dentist phobia.
Peter Horton
Soumia was fantastic during Inlay procedure making me feel comfortable and at ease throughout the process!
Michael Doherty

Russell Midgley
I recently visited for a filling on a chipped tooth and a root treatment. Dr Aisha was excellent - very professional, friendly, and made sure I was comfortable throughout the procedures.
Jin Jieh Kok
I was abroad and broke my front two teeth whilst on holiday in Spain in 2014. From first moment Ahmed looked at photos and explained all my options in simple language, putting me at ease about the emergency dental care I received. And since then, any other dentist might have immediately pressured me into going for the high-cost implant options, but Sumaya & Ahmed cemented the work already done to make it stronger & I continue to use the remnants of my existing teeth to this day. I am so grateful to Clarendons & cannot recommend them enough for their honesty and expertise.
Qasim Nawaz
Excellent quality service from dentist Ahmed and nurse Jeni. It has restored my faith in dentists and I now have the smile I have always wanted. The price was very reasonable for the work I had done and I felt as though Ahmed advised me well regarding the options available and associated costs. The practice is very modern and well maintained and the staff are helpful and welcoming.
Dave Madon
I have had a severe phobia of the dentist for over 15 years and the level of service at Clarendon Dental Spa is second to none. Thanks to their fantastic staff I am now attending regular check ups and having treatment, which in the past I avoided as I was so afraid. My recent treatment with Ahmed and Jenni went successfully and I managed to get a filling and clean without anaesthetic. This would not have been possible without their expertise, professionalism and fantastic supportive manner. They really took the time to keep me comfortable and calm. I can't recommend Clarendon Dental Spa enough as they have genuinely transformed my perception of going to the dentist and helped me conquer a phobia, which I never thought possible.
Jo Nassor
Root canal, two words sure to strike fear into the bravest of people. I'm not brave, but not wanting to lose my tooth, and face an implant at £2500, I steadied myself and agreed to the work. Ahmed Al Ani, my dentist of many years, booked me in with the practice specialist for this work, Peter Nixon... After Peter, and his dental assistant, had fitted a temporary capping to the tooth I was referred back to Ahmed, the practice specialist in cosmetic dentistry. This is the Clarendon difference. Everyone has a specialist area and they alone do that work... I'm overjoyed with my new tooth.
Brynley Talbot
I had a root canal as a child on my front tooth and ever since it's been a horrible stained colour. In some photos it was really noticeable and I was so conscious of it. I looked in to getting a veneer to cover it, however when I went to see Ahmed Al Ani he said I didn't need veneers but internal whitening. It was a really quick procedure (about 10 mins) and the bleach whitened the tooth in 2 days. I'm so happy I didn't need to pay for veneers as my tooth is now the same colour as my other teeth and looks so much better! Ahmed al ani knows so much about teeth whitening, he explained everything in a lot of detail and could answer any questions I had. He was honest about what would work for my teeth and what wouldn't, advising me on how best to save money instead of pushing lots of treatments when they weren't needed. Thanks so much I wouldn't go anywhere for dental treatment after this experience.
