I've gone to my current dentist for years and he's always extremely reluctant to even do fillings (last time he gave me a speech about how you can't replace what "God gave you" so you should just monitor it or so.) I think there are some dentists that legitimately care.
EDIT: Mine is actually in a very wealthy neighborhood and the lady who runs the practice (I think that's how it works?) has a reputation for buying state-of-the art tech.
