Has anyone experienced this? After and during the wearing of my Miami J collar for almost 7 weeks my jaw hurt ans still hurts unbelievably. It feels like my bottom teeth have moved forward and my bite in the back is off. I mentioned it to my surgeon yesterday and he said to see a Dentist it may be TMJ. I know I don't grind my teeth and I am sure it was the collar, has anyone ever had this I see the Dentist tomorrow but I was just wondering.
