I am having crown work done. Full mouth. Bottoms finished and was fine. The day the top was prepped I completely lost my appetite. Wont eat a thing. If I pop my temps off I can eat, im very hungry. I asked Dentist if I can get my old bite, he said he's the expert. I havent been back, im afraid if he cements the permanent crowns I'll be screwed. At least now I can eat with the temps off. Anything similar happen to anyone.
