I did shadowing with several dentists. But I spent most of my time doing shadowing with one of them. She wrote me LOR. Is one LOR from a dentist enough? Do dental schools require LOR from all the dentists being shadowed?
Just one. I'd just ask her first. If she can't, I'd ask one of the others that you shadowed.
Is it applicable to ask for more than one letter? I'm curious because one of the dentists I shadow is well known at my state dental school, whereas another one I shadow is well known at the dental school for the current institution I attend.
Even with committee letters, you're only allow one other letter.
