I have been reading alot about teeth sensitivity, gum and jaw pain after RAI. I was dx with Graves about 2 months ago. After taking methimazole for two wks, I started having REALLY sensitive teeth and the pain gets worse until I take tylenol or ibuprofen. I am up to every three hours taking something for pain. My dentist, GP and Endo do not know anything about this pain-what is causing it. I have not had RAI, just methimazole. Bad thing is ..I was having no symptoms-the TSH and T4 showed up in routine blood work. I had breast cancer 7 years ago with chemo and radiation. then was dx with RA. I began walking, eating healthy, and felt better than ever - until Graves treatment. Any suggestions for the teeth/jaw/gum pain?
