I think, at this point, you need to look at switching dentists. Whatever they are doing isn't working with your daughter. It may not be their fault, but I think there's something to be said for trying a new place just for her peace of mind. She needs to go into another setting. I don't understand why you are not doing sealants. I've heard some people say that we need to go all-natural, but she shouldn't be having so many cavities. I think nitrous is not always a good idea - some people react badly to it. Perhaps you can meet with a new dentist first and/or have your daughter their for a consult only, no procedures. Ask, without her there, how they handle kids who have felt traumatized in the past. Perhaps he/she could explain to your daughter that they need to "paint" her teeth so she doesn't get any more cavities. Some dentists have a large treatment room with several chairs - perhaps your daughter could observe a number of kids getting worked on with no screams and no trauma - that might reassure her. The large open space might help - some kids feel so enclosed in a big chair in a small room with a hygienist or assistant looming over them. Perhaps their masks frighten her too. I also agree that they must be honest with her - none of this "tickle the teeth" stuff that isn't going to work for her. When my son was younger, we used 2 different dentists -- one had a waiting room full of old video games like PacMan, and the kids often went 30 minutes before their appointment so they could play. Then they were invited to stay afterwards as long as they wanted to play games. It turned it into a great experience. Another dentist had 2 gentle hypoallergenic dogs (I forget what they were now, maybe Maltese) - the kids could choose which dog sat with them in the chair for a while. It was unusual but effective and very calming. The staff took an instant picture of the kid with the dog and gave it as a souvenir. Again, it was more fun than the typical treasure chest prize and a sticker. Ask your pediatrician for a referral to someone new, and then interview that referral. Good luck!
