Dr. Spackman appears in the room as gks. Dr. Spackman has practiced in Oral and Maxillofascial Surgery since 1980. I have trained at the Mayo Clainc and practiced for many years. Try to keep a record of the pain, exact positions and durations. You could have a cracked tooth and if you grind your teeth at night this could set it ofdf.
Cracked teeth are hard to pin point.
I have had FM for over 13 years and recently had oral surgery performed for cemental dysplasia under a bridge 6 weeks ago. Ofcourse the FM flared up big time since then. Correcting the bite may help just because there may be less abnormal stresses on the joint but just look around at the number of people that have abnormal bites. There is no one to one relationship. I do not think a mouth guard will help the problem.
