Saving your natural tooth — comfortably, precisely, and with specialist support when it matters most.
Root canal treatment has a reputation that far outstrips reality. For most patients, it is no more uncomfortable than having a filling — and the relief it brings from the toothache that prompted it is usually immediate. More importantly, it gives a tooth that would otherwise need to be removed a genuine chance of lasting for many more years.
At Conway House Dental Practice, we offer root canal treatment as part of our general dental care, supported by two advanced dental operating microscopes for enhanced precision and accuracy. For complex or re-treatment cases, we have Dr Anand Mistry — a clinician who limits his practice entirely to endodontics — available in-house. Patients from Marlow, Beaconsfield and High Wycombe can access both levels of care without referral to another practice.
What Is Root Canal Treatment?
A root canal treatment (RCT) is a dental procedure designed to save a tooth that has been badly damaged by decay or infection. When bacteria reach the inner pulp of the tooth, they can cause severe pain, sensitivity, and even an abscess.
During a root canal, the infected tissue is removed, the inside of the tooth is thoroughly cleaned, and the tooth is sealed with a filling or crown to restore its strength and function. This procedure relieves pain and prevents the need for extraction. With modern techniques and local anaesthesia, root canals are now more comfortable and efficient than ever.
Book Your Appointment at Conway House
If you are experiencing toothache, sensitivity, or swelling — or have been told you may need a root canal — we are here to help. Root canal treatment at Conway House is carried out with precision, care, and the specialist support of Dr Anand Mistry available for cases that need it.
Contact us today to book an appointment. We see patients from Marlow, Beaconsfield and High Wycombe, with same-day emergency appointments available when needed.
Root canal treatment becomes necessary when the soft tissue inside the tooth — the pulp — becomes infected or inflamed. Common causes include:
Severe decay — when a cavity is left untreated, bacteria can travel through the enamel and dentine into the pulp, causing pain and infection.
Dental trauma — a cracked or broken tooth from a knock or injury can expose the pulp to bacteria, even without obvious decay.
A leaking restoration — a filling or crown that has failed over time can allow bacteria to re-enter the tooth and reach the pulp.
Repeated dental work — a tooth that has been treated multiple times can develop pulp inflammation as a cumulative result.
If left untreated, pulp infection leads to severe pain, swelling, abscess formation, and ultimately tooth loss. A root canal removes the source of infection, eliminates pain, and preserves your natural tooth — avoiding extraction and everything that comes with it.
No pain — the procedure is carried out under local anaesthetic. You will not feel pain — just pressure and movement, similar to any other dental treatment.
Rubber dam for comfort — a small protective sheet is placed around the tooth to keep the area clean, dry, and isolated throughout treatment.
Treatment time — a root canal typically takes one to two hours, depending on the complexity of the tooth and the number of canals involved.
One or two visits — most cases can be completed in a single appointment; some more complex cases require a second visit to ensure thorough cleaning and sealing.
Advanced microscope technology — at Conway House, we use two dental operating microscopes to achieve magnified, precise visualisation of the canal system — significantly improving the accuracy and thoroughness of treatment.
If you are nervous about the procedure, speak to our team before your appointment. We can discuss your concerns and, for patients with significant dental anxiety, IV sedation is available alongside root canal treatment.
Signs You May Need a Root Canal
Sometimes there are no symptoms at all — infection is detected on a routine X-ray before it causes pain. More often, patients notice one or more of the following:
A persistent, throbbing toothache — particularly when biting or applying pressure.
Prolonged sensitivity to hot or cold that does not settle after the source is removed.
Swelling or tenderness in the gum near the affected tooth.
A small pimple or spot on the gum — this often indicates a draining abscess.
Tooth discolouration — a darkening or greying of the tooth.
If you are experiencing any of these, contact us promptly. Earlier treatment is simpler, more comfortable, and gives the tooth a better long-term outlook.
After Root Canal Treatment: Protecting Your Tooth
A successfully treated tooth still needs the right restoration to protect it long term. Root-treated teeth are more brittle than vital teeth and significantly more prone to fracture — particularly in the back of the mouth where biting forces are greatest. In most cases, a crown is the recommended next step.
At Conway House, this transition from root canal treatment to crown is handled seamlessly in-house. Mr Ashok Vijayakumar, our Consultant and Specialist in Restorative Dentistry, designs and places crowns for root-treated teeth with the precision his specialist qualifications (M.Pros RCS Eng, FDS RestDent RCS Eng) reflect. Getting the crown right matters as much as getting the root canal right — and having both available in one practice makes the process straightforward.
When Specialist Support Is Available
Most root canal treatments at Conway House are managed within our general dental team, supported by our advanced microscope technology. For cases requiring additional expertise, specialist support is available in-house:
Complex or Re-treatment Cases — Dr Anand Mistry, Endodontist
Dr Anand Mistry limits his entire practice to endodontics and holds an MSc in Endodontics alongside his dental qualifications. He manages teeth with complex anatomy, calcified canals, previous failed root canal treatment, or cases referred by other practices for specialist-level care. Having this expertise in-house means complex cases do not require referral to a separate specialist clinic.
Periodontal Connection — Dr Mital Patel, Specialist in Periodontics
Advanced gum disease can cause bone loss around root tips that closely resembles — and is sometimes confused with — pulp infection. Where a “perio-endo” presentation is identified, Dr Mital Patel, our Specialist in Periodontics, works alongside the treating dentist to ensure the correct diagnosis and the right treatment is carried out. Treating the wrong condition wastes time and may leave the underlying problem unresolved.
If a Tooth Cannot Be Saved — Oral Surgery and Replacement Planning
In rare cases where a tooth is beyond saving, Mr Dipesh Patel, our Consultant Oral Surgeon, manages extraction in-house — and the conversation about tooth replacement (dental implant, bridge, or denture) begins immediately. Patients are never left without a clear plan for what comes next.
FAQ
Frequently asked questions
Does root canal treatment hurt?
The procedure itself is carried out under local anaesthetic and should be painless. Most patients are surprised by how manageable it feels. Some mild soreness in the days afterwards is normal and settles with over-the-counter pain relief. The pain that patients most commonly fear is actually the toothache before the treatment — root canal relieves that.
How many appointments will I need?
Most root canals are completed in one to two appointments. Simple front teeth with a single canal are often done in one visit. Multi-rooted back teeth, or cases where infection is more established, may require two. You will be given a clear expectation at your assessment.
Do I always need a crown after a root canal?
For most back teeth, yes. Root-treated teeth are structurally weaker and at real risk of fracturing without a crown to protect them. For some front teeth under less biting load, a well-placed composite filling may be sufficient. Your dentist will advise on the best option for your specific tooth. At Conway House, crowns following root canal treatment can be designed and placed by our Specialist in Restorative Dentistry, Mr Vijayakumar, for cases where the highest standard of restoration is needed.
What happens if I do not have the treatment?
Untreated pulp infection does not resolve on its own. It spreads through the root into the surrounding bone, causing worsening pain, swelling, and abscess. Antibiotics may temporarily reduce symptoms but will not cure the infection. Eventually the tooth will require extraction. Root canal treatment is almost always the preferred option — it preserves bone, maintains your bite, and avoids the cost and complexity of replacing a missing tooth.
Can root canal treatment fail?
In most cases, root canal treatment is successful and the tooth remains healthy for many years. Occasionally, infection can persist or recur — often due to a missed canal, a leaking restoration, or new decay. In these cases, retreatment by Dr Anand Mistry, our dedicated endodontist, can often resolve the problem and give the tooth a second chance.

I visited The Conway Practice recently after a few years of absence, on my latest appointment I had temporary crown fitted and old filling replaced . From the moment I entered the practice I was welcomed by friendly and professional team. Dr Chanvir who I had appointment with was very professional, friendly and made me feel very comfortable and I felt he really cared. He explained everything in details what needed to be done and I was asked throughout the treatment if I was ok and comfortable. The whole treatment was really amazing . Unfortunately, after few days I had to come back to the practice ,as I had a little discomfort on my new filling. I explained at the reception desk about my problem and without hesitation I was booked to see Dr Hardeep(Harry) who came after a few minutes to welcome me , I was even offered a cup of coffee while I was waiting , wow. Even more impressive I was when Dr Harry within a minute discovered what was the problem with new filling and with a little of grinding/polishing work he fixed it . The treatment took just about 10 minutes , all good now. Excellent dentist practice , professional dentists .Also, nice and friendly staff . Highly recommended, well done Conway House .

I had an emergency appointment at Conway House and was really impressed with the service. Maria, the assistant, even stayed back longer to help Harry, so that I could have my treatment. Everything was handled very efficiently and quickly – I was in and out without any stress. It’s a shame they’re based in High Wycombe, as I’d happily become a permanent patient if they were closer. Highly recommend!
We attended Conway House with our 1-year-old for an emergency appointment and I couldn’t be more grateful for the amazing care we received. Cheryl on front of house was so welcoming and reassuring from the moment we arrived, which instantly put us at ease. Dr Basra and Nurse Alina were both superb in surgery – professional, kind and absolutely wonderful with our little man. Thank you all so much for making a stressful situation so much easier. Highly recommend!
Harry (the owner) was incredible throughout my treatment.From the very first call with Harry, I was pleasantly surprised that he was available on a weekend and took the time to answer all my questions. This immediately gave me the confidence to book a consultation. From the start, he welcomed me warmly and put me at ease despite my nerves.Initially, Harry reassured me that he could fix the problem I first came in with.For anything else I needed, he was two steps ahead—asking me what I actually wanted, coming up with solutions, and giving me the different options to choose from which was a great refresher.Harry is genuinely focused on providing treatments that deliver results. He’s not about upselling or pushing unnecessary procedures. Instead, he offers options that are tailored to what’s truly needed. His good intentions and honesty made a big difference to me throughout my care, which really showed me that he had my best interests at heart.What stood out most was Harry’s leadership, is that he reassured me that anyone he referred me to, would be just as good as him.He even came into my first hygiene appointment to explain my case directly to the hygienist. Here is where I felt reassured, knowing Harry is truly in the trenches with his team.He recommended Arjun, who quite literally saved my tooth. From the beginning, Arjun took the time to ask me questions to understand me as and my values, ensuring his approach aligned with my goals. He genuinely wanted to help me achieve the best possible results and took the time needed where I felt supported.Harry stayed involved every step of the way alongside Arjun, ensuring my treatment was seamless. Having both of them supporting me, gave me real confidence throughout, and it’s why the results were so positive. Arjun was professional, attentive, and calm—he kept me informed at every stage, explaining the aftercare, and reassured me about what to expect while the nerve settled. This education helped so much.No problem is too small for Harry—ANYTHING you ask him to do, he will do it! That’s the key approach that has helped me immensely throughout this process.I will no doubt be having further treatments with Harry and already can see that he is more confident in treating them, which is a great reassurance. I am looking forward to this and perfecting my smile.Hygienist:Umar was outstanding from start to finish. He made sure I was comfortable and listened carefully, allowing me to ask questions if I needed anything, which was great as I needed the numbing gel. He clearly explained why gums bleed and showed me exactly how to clean properly. What impressed me most was that both Umar and Harry introduced me to a specific angled brush for my gum line—a total game changer. His thorough clean meant that within just two weeks, my gums improved noticeably and my teeth have never felt so clean. Harry even came into my first hygiene appointment to explain my case directly to Umar, which reassured me knowing Harry is in the trenches with his team.Dental Nurses and Receptionists:The dental nurses always had a smile on their faces and were incredibly attentive. You could tell they genuinely enjoy the work they do, which made the whole experience much more pleasant. The receptionists, Cheryl and the team, were equally attentive and proactive; whenever I needed to make a change, they didn’t hesitate—they sorted it straight away, even when I told them not to bother yet! It’s clear that Harry has created an environment where everyone wants to be there, not just has to be. That positive vibe really shows in the care they provide.

I’ve always been a very nervous dental patient and had avoided going to the dentist for years. Last year, I needed an emergency appointment and Conway saw me within 2 hours and fixed my tooth pain. The service was excellent, and all the staff were incredibly friendly and reassuring. Since that first visit, I’ve had several procedures at Conway and my whole family have moved over to them. I can’t recommend them highly enough.

I had been putting off a deep clean for years due to fear and discomfort, but Tia at Conway completely changed my experience. I was dealing with a lot of bleeding and knew I needed to be seen. Tia was incredibly thorough, gentle, and made the whole process easy and pain-free. I can’t recommend her enough. She’s fantastic!
My wife and I have been using Conway for years and can’t recommend highly enough the dentists and hygienists. They are exceptional at looking after your teeth, share oral hygiene advice and maintain a professional attitude. The reception staff is also helpful and polite, apart from a strange interaction yesterday where a receptionist told me off about the way I pronounce my name :D Unnecessary comment but I laughed nevertheless :D
Genuinely brilliant dentist - great care, welcoming staff, always have time for their patients and have amazing out of hours and emergency care if you ever do need it.

I have been with Conway House Dental Practice since 2010, and I cannot recommend them highly enough. As someone who has struggled with dentophobia, I used to move from one dental surgery to another due to complications after each treatment—until I met Dr. Harry.Dr. Harry has provided effective solutions for all my dental issues. He never hesitates to attend to me, in any emergency situations, and his level of care has remained consistently excellent from day one. I've never felt as safe or well cared for anywhere else.I wholeheartedly recommend Conway House Dental Practice for their outstanding service and exceptionally high standards.Trisha K Visvanathan
