My kids haven't had fillings, but we really like Duke Pediatric Dentistry with Drs Keels and Neal. My dd1 had a bit of a phobia about drs so when I was choosing a dentist for my kids I wanted to everything I could to make it easier on her. Both the dentists are women (which was important for dd1 at the time) and their office has tons of bells and whistles. We were looking for a lot of distractions, so that was very good. They have video games in the waiting room (my girls have never played, but they have looked at them), big fish tank, very cheery bright office, friendly staff, treasure box and stickers, etc, after the visit. The examing areas are set up with multiple chairs so that my girls can both have an exam and cleaning simultaneously and I can be sitting right between them holding whoever's hand needs holding. It's worked well for us.
All that said, they're not alternative or holistic in anyway. They follow mainstream procedures with X-rays, fluoride varnish, etc. I'm okay with that, though. I really just wanted to ease my anxious girl into the chair and it's worked. Now she almost looks forward to going. We where there on Tuesday as a matter of fact and both my girls did really well.
I know other folks in the area who have had work done on their kids' teeth who like them, too, but ymmv. So far we've been able to avoid that. I know that they do have privileges at Duke Hospital if a very young child needs to have general anesthesia to get fillings or crowns.
