Dr Vainer did several fillings for me after I spent several years drinking too many free sodas at work and not going to the dentist. He is knowledgable and competent, however there was at least one occasion when he seemed to be pushing his assistant to do things she didn't feel ready to do (while helping with a filling). I've had mixed results; one tooth-colored filling has a new cavity growing at the edge, and one filling between molars is shaped so that it is impossible to floss without cutting my gums there.
His office staff were friendly but not especially helpful in dealing with the insurance company when we had a billing dispute.
