I need help! 2 weeks ago I had 8 fillings done, and had my mouth open for about 2 and a half hours. About 4 days later I started having severe pain throughout my whole face and jaw area, both sides. When I finally got in to see my dentist, she didnt' see any signs of infections or reason to do a root canal. She did filed down several of my teeth because my bite was pretty off after having all that work done. She said to try to give it a couple days and see if it goes away. She prescribed antibiotic and vicodin for the pain. A few days later I went to my primary physician thinking maybe I had a sinus infection and wanted to rule it out. He said it was muscular like a sprain, due to my jaw being stretched so much. I can't open my jaw all the way either. I does hurt on the right side when I open it too far. He gave me a muscle relaxer. Not helping. Is it common to have such severe facial muscle pain like this after having lengthy dental work? I don't know what else to do. My face just hurts really bad. I'll probably go to another dentist for a second opinion, but this is really disturbing. Thanks in advance for your help.
