Invisalign That Changed my Smile - Birmingham, GB

Because he's the best; he is our family doctor. Dr. Kumar is very professional at what he does and i am very pleased with the outcome of the invisalign and I would definately reccommend him. I feel confident to smile with the end result, it's a shame he is leaving and he will be greatly missed. he has been our family doctor for ages. Dr. Kumar always goes above and beyond his call of duty.

Extremely Pleased - London

I can't recommend Dr Kumar highly enough. I felt Dr K's knowledge, experience and professionalism put him way ahead of the rest. The entire procedure and outcome has only validated that. But don't take my word for it, do what I did: Speak to many and visit several providers, I would be very surprised if you didn't agree with me, and go with Dr Kumar for cosmetic dentistry treatment. Thank you Dr K for my happy smile!
