I had two crown preps on October 1, 2014..About a week later, I noticed i could not open my mouth fully..after a few weeks, i went to see an oral surgeon, and he said my disk was out of joint..he put me to sleep, and put my disk back in place..it felt better..no more ear pain and jaw pain, but i still could not fully open my mouth...it is now Novemeber 19, 2014, and i can still only open my mouth wide enough to fit two fingers..I had an MRI and the nurse said it was fine, but the doctor never called me back...what do i need to do now...take my MRI to another doctor? is my disk back out of joint, or are the muscles too tight?
