At Surbiton Smile Centre, our priority is to save your natural teeth while keeping you comfortable. Root canal treatment is a routine procedure our experienced dentists carry out with precision and care, using the latest techniques and equipment. Whether your tooth has one simple root or several complex canals, we carefully remove infection, clean and seal the area, and restore strength with a filling or crown. Thanks to modern anaesthetic and gentle methods, most patients find the treatment no more uncomfortable than having a standard filling—helping you get back to smiling without pain or worry.
Understanding Root Canal Treatment and Its Key Benefits
Root canal treatment (endodontic therapy) is a procedure designed to save your natural tooth and protect your oral health. It is usually the preferred option over extraction because it preserves your smile and offers long-term benefits.
When the soft tissue inside the tooth (the pulp) becomes infected due to deep decay, cracks, or trauma, root canal treatment is needed. If left untreated, the infection can spread, causing pain or even tooth loss.
The treatment involves gently removing the infected pulp, cleaning and disinfecting the canals, and sealing them with a safe filling material. Finally, the tooth is restored with a crown or filling to provide strength and function.
Benefits of root canal treatment include:
- Saving your natural tooth – maintains your bite and smile
- Restoring comfort – relieves pain, toothache, and sensitivity
- Strength and durability – with a crown, the tooth functions like normal
- Stopping infection from spreading – protects surrounding teeth and gums
- Cost-effectiveness – avoids more complex treatments like implants or bridges
In short, root canal treatment relieves pain, prevents further infection, and helps preserve your natural teeth for years to come.
Root Canal Procedure in Surbiton
Step-by-Step
Reasons For Root Canal Re-Treatment
Even though endodontic treatment is one of the most successful and predictable procedures in modern dentistry, failures can occur. Some indications of failure include swelling, soreness or the persistence of abscess at the root tip as identified in an X-ray. When this happens, a root canal revision procedure, also referred to as “re-treatment,” may be warranted.
- Retained microorganisms (bacteria) in the root canal
- Breakdown or corrosion of root canal filling materials
- Contamination from decay or leakage from a failing restoration
- Inoperable canals because of calcification or unusual anatomy
- Sometimes tissues fail to heal for unknown reasons
Although re-treatment is technically more difficult than the original root canal, it can usually rescue a failing condition without having to consider surgery. We at Surbiton Smile Centre are especially well equipped to handle these difficult conditions because of our additional training and experience.
Endodontic Surgery
Conventional root canal treatment is not always sufficient to correct every patient’s condition. Occasionally, endodontic surgery is required. This is because a previous treatment has deteriorated or because anatomic considerations such as the shape of the tooth or canal space make the traditional root canal treatment especially difficult to complete.
Root Canal Treatment After Care
If you experience sensitivity following a root canal session, we recommend you take an anti-inflammatory drug such as ibuprofen to reduce inflammation, which will in turn reduce pain. You may also want to apply ice to the outside of your face next to the tooth, keeping the head elevated.
Under no circumstances should you apply heat to the outside of your face. Consistent medication is the key to comfort. It is essential to follow your dentist orders by taking prescribed medications to alleviate pain and to help prevent or fight infection.
Avoid hard or sticky foods until the final crown or filling is placed.
If discomfort lasts more than a few days or if you have severe pain or swelling, call our office. We will suggest medication or other steps to make you more comfortable

Dr. Simin Soltani
DDS . MSC . SWEDEN
Principal Dentist and founder of Surbiton Smile Centre since 2002, brings over 31 years of global experience, trained at the Karolinska Institute (Stockholm), Eastman (London), and Münster, Germany.

A compassionate advocate of preventive and minimally invasive care, she’s known for delivering aesthetically mindful treatments that stand the test of time.
“I’ve been visiting the team at SSC for 9 months or so. My treatment included a front tooth implant plus upper and lower alignment. From start to finish the team were fantastic – especially good with appointment times, availability and patient communication. I’ve recently concluded my treatment and I couldn’t be happier with the results. I’d highly recommend to someone looking for first class cosmetic dental treatment. Thank you Simin, Theo, Claudia, Fernanda and Wendy.”
“Really happy with this practice – Dr Soltani is lovely and a very good dentist. Waiting times are close to none and the staff are professional and friendly. I did a teeth whitening treatment with the Enlighten method and worked amazingly.”
“She was brilliant. She explained exactly what she was doing. Reassured me thoroughly and I felt at ease. Considering it was Good Friday and in the evening, the price was very fair. If you are in need of a Dentist, then definitely call them.”
I had my Invisalign treatment here and am very pleased with the results. This was with the recommendation of Sure Smile aligners which have worked well. Special thanks to resident orthodontist Theo, Simin and the rest of the team as they are all very professional and friendly.
Dr Soltani and her team at Surbiton Smile Centre has given me exceptional service over the last 5 years. The whole team are highly experienced as well as very friendly. I have done an implant, a crown and braces – all treatments were of first-class. I will certainly continue to let them look after my dental health and strongly recommend Surbiton Smile Centre!
I have been going to Surbiton Smile Centre for nearly 20 years, that is surely testament to their service, friendliness, advice and overall experience. Fine fine work Simin and Wendy!
Dr Simin Soltani and the Surbiton Smile Centre team have been world class. The professionalism, quality of treatment, and customer experience have been exemplary.
I needed quite a bit of dental work so went to a few different surgeries to get their opinions. I chose Surbiton Smile Centre because Dr Soltani actually gave me options – all of which would work to varying degrees and, significantly, to varying costs. She took the time to try the most cost-effective option, but always with the possibility of shifting course if needed. Eventually, to get my teeth decently functional, I needed quite a few crowns – including on front teeth. She allowed me time to get used to the adjustments as the process went on, and always made sure each stage was both comfortable and looked good. I am very pleased with the result, again both aesthetically and functionally. Would most heartily recommend!
I recommend my dentist, Simin with the highest regard. Over the years, she has transformed my problematic mouth to a smile of stable, healthy teeth.
Simin has restored an old implant for me and also inserted a new one. She has helped me with crowns and also replaced old black fillings with natural looking white ones. Simin has always been very professional, kind and helpful.
Thank you Simin!
