You poor thing! I had this last year, and eventually had all teeth pulled out. I found a numbing mouth rinse quite helpful, along with neurofen plus - I can't remember what it was called, but I basically just held some in my mouth where the pain was until it went completely numb, and that helped a lot. Your chemist should be able to help. If you aren't into pharmaceuticals, apparently pure clove essential oil has a numbing effect too. Good luck!
