I go to a dentist who does specialize in it. He is one of the leading when it comes to treating TMJ, and has traveled all over the world doing seminars. I have taken care of the first few steps in treatment, but I need $4000 for the next. :-/ It will be awhile.
He has done consultations and scans so far. The next part includes work with a tens unit to see how my jaw reacts and having a mold made. He believes your teeth should be built up or filed down in places to correct alignment. When he makes the guard for your mouth, it factors this in. You wear it 24-7 until your jaw is used to the new position. He makes adjustments during that time, and when he removes it, he builds your teeth up to match. I don't even want to know how much that costs.
He is good, and I will have a perfect smile when all is said and done, if I can afford it. I might have to go another route, though I would love to do this. My dental insurance is no help.
