I have been experiencing sensitivity in my upper right hand molars along with dull headache pain almost weekly. I have tried a mouthguard, as I suspected the headaches were caused by grinding, but they are still occuring. Does anyone have an idea of what this may be caused from and suggestions for treatment?
Have you been to a dentist? You might have TMJ. You need to go to a dentist and have an examination and x rays. If a dentist is unable to determine the cause then you might want to get a physical from you MD.
