My 12 year old son was very scared to go to the dentist and I told this to the staff. We had to wait an 30 mins to see the dentist and when he came in, I was standing next to her, holding her hand and he ripped her hand out of mine and told her that she was being a baby and roughly put her hands in her lap and told her to keep them there.
After that, we had to wait almost another hour for them to figure out why his pain would not go away.
