I've been to Dr. Tanveer for 4+ years now and he's clearly one for whom dentistry is more passion than profession. This naturally leads him to undertake continuous development in his field and coupled with his empathetic and affable nature, excellent communications skills and a genuine desire to make every patient feel at ease, is what I'd consider makes him a very, very good dentist.
If anyone can help minimise your fear of a dentist, he can. I don't know if he's the best though...simply because I haven't cared to look any further.
