You are definitely not alone! I have horrible dental anxiety too! In fact, I just got home from the dentist this afternoon getting a permanent crown placed, a cavity filled, and a crown buildup and temporary crown on the other side of my mouth. At least nitrous helps...though of course they charge an additional fee for it, and I'm thinking no F*ing way I'm ever getting a crown without nitrous again. Did that once and never. ever.again. If you need a crown to fix the filling, definitely get nitrous if you can. And it doesn't help that everything the dentist does costs a fortune even with dental insurance!
