If I don't like my dental hygenist (sp?), it's all over for me because that is who I spend the most time with. I have to like the dentist (ie: trust him) but you also have to like and trust the person cleaning your teeth.

Would I get a 2nd opinion? It depends. How long since you last saw "your" dentist before this new one? Did he/she say anything about those crowns being needed or keeping an eye on your old fillings? If not, I would wait a bit unless those teeth are causing you pain. I once had a dentist tell me I needed to have a root canal on a tooth and I didn't trust him so I went to me old dentist (who wasn't covered by my insurance) and he said it wasn't a root canal thing but rather an exposed section of my gums causing the root be sensitive. Told me what to do and viola...lots less pain (I have gum recession so pain isn't entirely gone).

Trust your gut
