There's a pediatric dentist in Draper called "Out Of This World". Once or twice a week, one of their dentists switches hats to be an adult dentist. I don't recall his name, I just say "Yeah, I need to make an appointment with the adult dentist."
My wife and I use him, because it keeps it simple doing everything in one office.
The guy is good, and isn't out to rob you blind - he only does things that you truly need. It might seem odd going to a kid's dental office, but I've been nothing but impressed with the guy.
