I am in Hanover and I take my kids to Artistic Dentistry, they are great! I brought them to a couple of other places that wouldn't allow you to go in with them and it just didn't work for my kids. This place is fabulous! They are quick and they always get a prize! My kids daughter who at the last dentist wouldn't open her mouth, loves going here. I wouldn't get to into detail about what they do, just let her know that they are going to look in her mouth and when she is done she will get a prize! Here is their website, they really are great!! I tried the pediatric route but I found they were really expensive and this place is geared for kids as well as adults!
