Dentist was VERY RUDE. I think he must be slightly off his rocker. The dental assistant said to open wide and he says, "You don't have to open like a jerk!" I'm not even sure what that means. He also snapped at me for being nervous when he was scraping at my teeth. He then yelled at me for trying to tell him that the numbness was wearing off. It was horrible, and I felt obligated to put up with it because I had already paid for the permanent crown.
