The Best!I have been introduced to Dawood & Tanner about 3 years ago and had visited the practice since than for many teeth issues, from root canal treatment, extraction, implant and regular hygienist check ups. The whole team is highly professional and so welcoming, including the reception members. They will always give you all options and would support you throughout the treatment and post check ups. Professor Patel, Dr Fiona McKillop and their teams helped me so much and would recommend them highly. Also my hygienist Elisabeth always helps me with great advises how to keep my teeth and gums healthy. Thank you all very much!Salvatore G. ★★★★★ I've been a patient of the Dawood and Tanner practice for a few years now. I have a slightly complicated dental history, and thanks to the kind help of Doctor Fiona and Shannon, I've been able to greatly improve my situation and keep my dental health in check. I should also mention Elena, my hygienist at the practice, who's advice has helped me a lot, with many tips on how to improve my daily routine and the overall health of my teeth and gums.Caroline P. ★★★★★ Clean, friendly professional dentists. Can’t fault Prof Patel and his team.Nick B ★★★★★ Great practice.Shannon Patel is both extremely talented and friendly, and all the staff I've interacted with are very professional.The dental hygiene with Agnieszka is excellent too!P C. ★★★★★ Dawood and Tanner is an amazing Specialist Dental Practice, and I cannot recommend them highly enough!I had extensive surgery on my jaw sixteen years ago and as consequence of this and other factors have severe gum recession and loss of supporting bone around many teeth.I was told prior to seeing Dr Dawood that my case was very complex; that there was not enough bone for implants, and I would have to have a bone graft and ten teeth removed. I did not know what to do until I saw Dr Dawood: he put my mind at rest immediately by his confident and practical approach. He is very understanding and sincere and adopts a conservative approach. He also referred me to their Consultant Endodontist, Professor Shannon Patel, who is very easy to talk to, funny and down to earth: he too has a vast amount of knowledge. He examined my mouth very thoroughly and gave me hope that the some of my teeth could be saved….I had four teeth removed two weeks ago, two implants and a gum graft and very little pain. Hannah Fullerton was there for the whole process and assisted Dr Dawood; there are no words to express my thanks to her too as she is very patient, caring, and empathic: she, along with Dr Dawood made the whole process soooooooooooo easy and explained everything fully.I also want to say a special thanks to their hygienist Elena who gave me so much information and put my mind at rest by her understanding and compassionate approach.So – if you need implants or want to save your teeth then Dawood and Tanner is the place to go: their professional, honest, and practical approach is world class😊.Christelle ★★★★★ I have had the privilege of being treated by two dentists at Dawood and Tanner, Dr. Shanon Patel, and Dr. Francesca Tosson.Dr. Shanon Patel saw me for my re-root canal and was able to save my tooth in what ended up being an intricate and difficult procedure. I felt like I was in skilled hands and I’m immensely grateful to him for having staved off my need for an implant for a few more years. While I was in his chair, he noticed fissures in my teeth which he attributed to clenching. He recommended treatment to fix and prevent further damage.This is when I started treatment with Dr. Francesca Tosson. Immediately she recognised that I would be put most at ease by being talked through a given procedure. She took the time to assuage any concerns about a process, and talk through the decisions she makes on my behalf. Her priority was the long term health of my teeth, and I’m thrilled with the outcome of the number onlays, composites, and crowns we’ve had to do. My teeth look and feel natural. I always feel incredibly relaxed and comfortable in her chair knowing that I am in excellent hands.The staff, the nurses, the technicians have also all been lovely. I could not recommend Dawood and Tanner more.js_loader

Failing Root Canal


Root canal re-treatment Before Root canal re-treatment after

We often treat patients referred to us with problematic (failing) existing Root Canal treatment. There are many reasons for this, including, the tooth not being suitably restored resulting in extensive unmanageable dental decay, or an untreatable crack extending into the root and/or due to the complex root canal system not being adequately disinfected and/or sealed.

In the majority of these cases, this can be rectified by re-examining the existing treatment to remove the root filling material, and then thoroughly disinfecting and sealing the complex root canal system. Once treatment is complete a well executed bonded restoration or crown will be required to enhance the longevity of the tooth.

This treatment preserves your OWN natural tooth usually in a single appointment thus avoiding an extraction or a dental implant.

However, in some instances root canal re-treatment may not be viable, but this may only become apparent once the treatment has commenced. For example, the tooth may not have sufficient remaining sound tooth structure remaining to restore it with a crown. In other instances, it may not be possible to completely remove the existing root filling material and thoroughly disinfect the root canal system. In these cases, extraction may be advised and the tooth replaced with an implant retained crown, a bridge, or occasionally a denture.

Dental trauma is relatively common, it has been reported to occur in as many as 20% of the population.

We commonly utilise 3D scans to help diagnose the severity of the dental injury. At Dawood & Tanner we have a particular expertise and holistic approach in managing dental trauma. In our experience these types of injuries often require a multi-disciplinary approach, for example, deciding on orthodontic treatment to realign teeth which have been accidentally knocked out of place, or even the necessity of an implant versus retaining the tooth. When required, root canal treatment is carried out as soon as practically possible. However, in many instances, we can carry out minimally invasive pulp cap treatment to preserve the healthy tooth and its pulp tissues (nerve and blood supply), thus avoiding root canal work.

Traumatised teeth may discolour with time, particularly if they are poorly root-treated; we offer focused whitening treatments to improve the appearance of discoloured individual teeth using an in-surgery or in-tooth technique.

Dental Trauma

It is essential that patients who have sustained dental trauma, no matter how small the nature of the accident, are reviewed on a periodic basis in the first year, and then annually thereafter.
