Yea, there are good ones out there. I had a horrible experience with unnecessary work done because I didn't know any better, drilled too deep, root canal, then installed a crown that cracked. Told me everything had to be filled.

Next dentist basically just said I need regular cleanings, or to learn to floss better. I've been going to him for 10 years now. Recommended lots of people to him.

Another signal is, how nice is their office? Is it a little converted bungalow with drop ceilings? Or a big modern monstrosity with floor ceiling windows.

I've also had experience bringing a friend to Mexico to get work done, which worked out well. Ended up saving a bunch of money, got the work done that day.
