I've been going to Dr. Flint for several years now... he's a top notch dentist. His staff is gentle, and he knows what he's doing.
I can't really speak to the price of things... my insurance has free preventative care, and a $75 deductable, so I've never paid attention to the cost.
One note: He moved his office to 91st and Toledo. It's kind of hard to find now. But worth the drive out there... it's nice that everyone there remembers my name, even if I'm only there every 6 months.
