I too have RSD and understand your fears.
I recently had to have a root canal. I was/am fortunate that my dentist was already aware and well educated about RSD.
I did not have to have a block.
RSD does affect my mouth but it doesn't feel any different today than before the dental work.
I would suggest talking with your daughters dentist... He/she may know about RSD if not... you may need to "educate" him/her.
I wish you and your daughter the best.

Abbie
