    I am so pleased with my new veneers. From the initial consultation, Dr Karthik made me feel at ease and kept me informed of every step. He is a perfectionist in his work and my confidence in him paid off. I would highly recommend Aviva. Thank you so much.

    I chose carefully when I decided to use a private dental practice and I’m glad I did. Aviva Cosmetic dental practice dentists are extremely professional and very caring, as are all the other members of staff, I wouldn’t hesitate on recommending the practice to anyone.

    I have had 2 fillings done by Brindha and she is probably the nicest dentist I have ever been to. She explains everything, gives choices and is so gentle and caring. If you are worried about visiting the dentist see Brindha and you really won’t be worried any more.
