I had this happen about two weeks ago. I thought for sure I needed to go see the dentist but within three days the pain subsided a little and radiated all over the mouth and I canceled the appointment. My lower right side was hurting and my upper was hurting. By day two, all my teeth were hurting. I do have TMJ and wondered if it was acting up. My sinuses are also bad so could be related. I knew when all the teeth started hurting it was something more than a toothache. I had xrays 6 months ago and all was fine and the dentist agreed and said come in if it starts up again. Hope your better soon.
