About Dr Cohan Rajan

In 1998, Dr Cohan Rajan graduated from the London Hospital Medical College, University of London with a Bachelor’s degree in Dentistry and a Masters in Science (Gerodontology). Following his graduation, he went on to undergo training in cosmetic and surgical dentistry. 

To increase his expertise, Dr Rajan has undertaken studies in the United States where he gained an Associate Fellowship from the World Clinical Laser Institute. In addition to this, he is an accredited Enlighten Whitening provider, a certified Platinum Invisalign provider, and is also certified to deliver Botox and Dermal Filler treatments.

Dr Rajan has a special interest in smile design and has performed numerous Same-Day Smile makeovers. His experience in this area has led him to teach other dentists about the use of this treatment, and to contribute to the Cosmetic Surgery and Aesthetics Guide.

In addition to being registered with the General Dental Council, he is a member of the British Academy of Cosmetic Dentistry and the British Dental Association. Following a year-long Dental Implantology training course, Dr Rajan is also a Fellow of the International Congress of Oral Implantologists.

In 2015, Dr Rajan obtained a Fellowship in Laser Dentistry from the University of Genoa and was also awarded Fellowship to the Academy of Dento-Facial Esthetics (NYC).

As a Dental Phobia-certified dentist, Dr Rajan is enthusiastic about helping patients with dental anxiety. To ensure all patients can access vital dental procedures, he uses sedation and was one of the first dentists in the UK to use Waterlase treatment.

I went to see Dr Cohan after being too scared to see a dentist for just over 20 years... I avoided going for so long as my entire younger life, dentists were unpleasant and despite having a good oral care routine, any fillings were made out to be my own fault, and any pain as a result of treatment was "deserved". I contacted Dental Spa and was invited to come to a consultation, was told we can go at my own pace and we'll take it from there. The whole way through I have been treated with kindness and sensitivity from the entire team. From the lovely Prem who first emailed me and helped me get booked in, to Fredi and Dr Cohan. I was offered a plan and options to deal with my fear. At no point was I made to feel silly or small and (as I was promised) all treatment was carried out in a way that I could cope with and the whole way through I've been informed on what's being done and why. I definitely feel more confident to maintain my dental health and would strongly urge anyone with the same fears to just go for a chat. It's a no-pressure consultation and everything will go at a pace that is comfortable. Thank you to Dr Cohan and his brilliant team.

I have just completed two years of dental treatment at Dental Spa, an achievement that has only been possible because of the kindness, patience and sensitivity of Dr Cohan, Pauline and Premek. They are a fantastic team. The results Dr Cohan achieved have been beyond my wildest expectations and my only regret is that I did not find them sooner. Having been unable to step inside a dentist’s surgery for years, the fact that I returned 20-plus times (often laughing!) is due entirely to them. I can't thank them enough for what has been a genuinely life-changing experience.

I am half way through treatment with Invisalign braces and the service and treatment is excellent. Although the cost of the entire treatment is high, I am able to pay with instalments on each visit. Cohan is excellent, Pauline is brilliant and the cute guy at reception will bring a smile to anyones face! Keep up the good work as I would would recommend you to anyone.

I highly recommend Dr Cohan Rajan and his team. I am always made welcome and put at ease throughout my appointment. Before I found Dental-Spa, I used to feel very anxious visiting the dentist. Dental-Spa has changed this completely. Dr Cohan Rajan is extremely friendly and professional and explains everything with great thoughtfulness. Dental Nurse, Pauline Lynch is very friendly and professional. Receptionist Johan is very welcoming and helpful. I truly enjoy visiting the dentist now. No more dentist phobia. Thank you Dental-Spa.

I would recommend Dr Cohan Rajan to everyone. Not just because he is exceptional at the job he does, but because he and his team provide support and help to those who may not always have welcomed a trip tot he dentist. When I first visited him my teeth were in a terrible way as I hadnt been to a dentist for about 10 years - due to a phobia following a bad experience. He coached me through some extensive work, and I have gone from abject terror, to looking forward to my visits!

I recommend Dr Cohan Rajan at almost every opportunity! I was surprised when my legs turned to jelly at the thought of seeing the dentist. I hoped to calm myself but was overwhelmed with anxiety. Cohan was incrediby kind and patient with me throughout the session. I truly felt that such a positive experience and outcome outweighed the negative thoughts and feelings I had prior to the appointment - in a way it resolved my fear. I now recommend all my friends and family to book in with Cohan for his excellent care and results and I will feel comfortable booking myself in for future appointments. I'm so relieved to have found a dentist that I feel comfortable with and feel phobia free now!

I highly recommend Dr Cohan Rajan for continued membership in this programme. Not only has he done an excellent job with necessary dental work to replace a number of crowns, he has always responded favourably and with concern to my long-established dental phobia. From explaining what to expect, to providing a calm, relaxed environment, to letting me stop the procedure (if practical) due to occasional freak-out moments, Cohan is a true professional, and I am happy for him to be my dentist.

I came across Dr. Rajan about three years ago when I was given a voucher from my son for a beauty day, I searched the book and found a Dentist which not only looked after your teeth but you could have a massage and other treatments. I booked a massage and while I was there I spoke with Cohan and mentioned to him that I was peterified of the Dentist, he told me about Dr.Rajan and nervously I agreed that it would be a good idea if I saw him. I have never looked back and now I even persuade my other "Dental Phobic" friends to see him. Everything in the surgery is first class, from attitude of staff and mostly the care and attention he gives to me on my now regular 6 monthly visits. I am now the proud owner of clean sparkling teeth and I can smile again. Thank you to Dr. Rajan and his team. Dorothy
