It started in June with some pain in my lower right jaw that started out as mind and gradually progressed. In July I got into my dentist where they xrayed and determined that I needed three filings in three teeth. After these were done the dentist thought that perhaps if symptoms didn't improve that one tooth might require a root canal. After a couple of weeks the jaw pain became very intense and I returned to the dentist. I took a course of antibiotics as I was having sinus issues as well. Upon inspection it appeared as if the root canal would need to be done on a tooth other than the one the dentist had thought prior. I had the root canal done (extremely painful). (Oh, after the initial fillings, I started having pain in my top right bicuspid as well) The pain subsided for only a day or so and returned. I returned to the dentist where she adjusted the bite on the right side after taking xrays of both upper and lower spots. This was two days ago. This morning I woke with no jaw or tooth pain but as I drove into work I had stabbing pain in both upper and lower jaw/teeth. This has continued throughout the day (eating or drinking only slightly affected this). I have been having a slight cloudy discharge and heaviness in the right face and ear. Help, please!
