I agree with Russ, it is very difficult to stand up for yourself because of the mercury and because they do get so offended and act like you are crazy, but you won't regret having asked the questions-you might regret not asking. I learned too that if I ask and they respond negatively, then they are not going to be helping me and I didn't waste anymore time with them and tried someone else.

I may be wrong, but I'm pretty sure that your dentist has to give your records to your new dentist and you have a right to all of your records as well.
