Orthodontics and Dental Specialists





We had the Invisalign braces fitted for our son is 15. Initially, he was against braces totally but after Dr Rachna Dattani went through all the pros and cons, he showed interest in proceeding with the Invisalign braces. We found the care from the first visit to the most recent one to be professional and helpful. Dr Rachna Dattani was able to fit in when we could see her, making the ongoing care easily accessible and manageable. It also meant we got the reviews regularly and checks on progress were made between sessions. We have been pleased with the care for the last 15 months and our son has managed this experience well. Glad it is done now and he is pleased with the outcome!

K.E. Testimonial

Undertaking orthodontic treatment requires commitment so it’s important to trust the doctor and feel at ease with them. With Dr Rachna Dattani, that was the case almost instantly and I didn’t have to consult other Orthodontists as felt I was in the best care at Precision Smiles. Dr Rachna was always smiley and pleasant even with all my early morning appointments and she always explained the technical aspects of the treatment while genuinely caring by always offering to adapt her diary/contact her when required. Having the treatment later in life (I’m 38)  has had the advantage of understanding the process, appreciating the benefits and  therefore resulting in taking better care of the teeth than perhaps otherwise. My initial view of Dr Rachna Dattani was correct as her care and experience was great and I’m very happy with the results as they are better than I had anticipated!

Z.S. Testimonial

My confidence has increased dramatically since having my smile transformed with invisible braces by Dr Rachna Dattani. She was so kind and made me feel at ease whilst having my treatment. I would recommend everyone to have their treatment started as soon as possible!
