Our ped dentist *expects* parents to come back into the room. They have a bay, rather than individual rooms, so there are lots of people around. They also have video games like centipede, and a nintendo for when kids are gettings meds in prep for dental work. I have to say that he is wonderful. He sings to the kids during exams (winnie the pooh, barney, whatever), his motto is "whatever it takes" to keep them happy and positive about the experience. Ds had to have several cavities filled a couple of weeks ago under GA at the hospital; before hand, when he came to check on us, last minute info, etc he brought ds a stuffed animal. As the meds were taking effect, that kept his attn so that he didn't even notice when he was going down the hall for the gas and IV meds. He was just as happy ad content as could be.
We drive 2 1/2 hours to see this man, he is so good. He also does beautiful work, too. If you are near the Dallas, Ft. Worth area, I can get you his info
edited to add: I have never in any of our visits seen a child act up or be scared, crying or nervous in the office. Despite the fact that he has a lot of special needs clients who have anxiety disorders, previous traumatic dental stuff, oral aversions, autism, etc. One time when ds tripped as he came in and cried a second or two, all the staff popped right up to make sure he was okay and not upset about coming in.
