Aw, that sucks! I haven't ever had a filling or anything, but I can imagine it would not be fun. I get anxious about stuff like that too. I had all my wisdom teeth out two years ago, and I made them put me completely under for it. In fact, I was so nervous, they even prescribed me a Xanax to take beforehand for anxiety. It was awesome! By the time I got there I was higher than a kite. Last thing I remember was checking in at the front desk. I woke up at home, in bed (thanks Mom!!).
