I had 6 fillings (some new, some replacements) 8 months ago. Since then I have had pain in 3 of those teeth. I\'ve had many high spots reduced etc but the pain persists when I'm eating (xray shiws nothing). My dentist has decided it is due to tooth grinding and fitted a mouthguard but this has not decreased the tooth pain and I now have terrible jaw ache in the mornings, so bad I can no longer open my jaw wide without pain. I don\'t know what to do as I feel the dentist is sick of seeing me.
