I think I have finally had a bad dentist experience. My new dentist doesn't believe in metal/mercury fillings and wanted to replace mine. Ok, I'm game, they're prettier and I have insurance. I have never been SO ABUSED in my life. Somehow they managed to have 4 hands in my mouth at the same time . After the novacaine wore off, my jaw was throbbing and swollen. Last night I couldn't even open my mouth to eat. It was TERRIBLE. Today, I'm munching ibuprofine and my jaw is begining to work again. I swear, I thought they broke it or something! The fillings are fine though...funny huh.
