Dr Shirazi is great, he is friendly and you feel in comfort in his care!

Dr Shirazi has been my dentist for many years and I highly recommend him. He is always informative and supportive and I trust him completely. Thanks doctor for all you do

I have been with this dental practice for the past 10 years and have always received excellent care from my dentist Dr. Prasad. I would recommend this dental practice. Friendly service and a dentist who cares for his patients’ dental health .

Undine S.

Had an appointment with Dr Romain Prassad today what a lovely and kind dentist really put me at ease and is doing everything he can to help save my tooth thankyou so much ☺️

Tor M.

I had a wisdom tooth removed and a filling today, I cannot fault my treatment! My dentist was very skilled and calming! I didn’t even feel the injections! Restored my faith in dentists! TOO CLASS!!

I would really recommend this Dental Practice. Dr Kolar is a very attentive dentist who cares about the you as a person as well as about the health of your teeth and gums. He takes time to explain the processes he is leading you through, explains how your dental health has progressed over time and encourages you to take care of your teeth. For the first time in my life I look forward to coming to the dentist!

Toby R.

I have been registered at this dental practice now, for just over 15 years. Throughout that whole period, I have been lucky enough to have been looked after by the wonderful, and patient, Dr Prasad. He has covered many procedures in my mouth, from extraction, and root canal, right up to the most recent procedure, Composite bonding of my broken two front teeth. Do not hesitate to register at this practise, as you will be looked after with care and consideration.

Thank you Dr Prasao

Suzanne L.

Very friendly

During the lockdown period I was able to see Dr Irfan for a dental emergency I had. I’m so grateful that they have been available throughout this. Gillian the practice manager contacted me and offered me an appointment the same day. I am a long standing patient at this practice and cannot thank them enough for great service they have provided to me throughout the years. Great dentist, staff and management. Thank you all so much.

Susan L.

The Dental Care Center has been an excellent dentist surgery that I have been attending as a patient for many years. When I was young I didn’t have a pleasant experience with my local dentist on more than one occasion. I found the dentist at Camden dental care center very reassuring and comforting. The management and reception were also very welcoming.

Stewart S.

Dr Yasha saw me when my teeth were a mess, I was super self conscious about it and it was affecting my life really negatively. I needed 3 bridges, which are still holding up great, and I’m on the practice plan so have the motivation to go in for regular hygienist and checkup appointments. Not only is my oral health better than ever, my overall wellbeing and peace of mind is immeasurably improved. The care and consistency of treatment I’ve received from Dr Yasha and hygienist Ramin has made going to the dentist (almost) a pleasure. 100% would recommend. Really great people doing excellent work.
