Ever since having my wisdom teeth pulled last summer I've had reoccurring pain in my upper jaw (towards the back) and pain in my sinuses after eating tough/stringy food like steak. It only happens after eating those types of food and flossing/mouthwash/brushing does not help. I went back to my dentist and told him of the issue, but he just figured my back molars had spread apart too much and filled in the gap a little (he pretty much ignored me telling him about the sinus pain). Needless to say, that didn't work. I should mention that this dentist is in WI (where I moved from). The only thing that takes away the pain has been ibuprofen. Also, the pain is a dull ache. I also brush 2x daily and don't drink soda, if that helps.
