I went to physical therapy when I first was diagnosed with tmj and it did help me quite a bit. My pt involved ultrasound massage with water in my mouth for 5 minutes on each side, then ultrasound without the water, then these little pad type things that pulsated ultrasound waves on each side for 5 minutes. It felt great and I loved it. It did help me for a while. I wish I would have stopped there. Instead I agreed to a very minor surgery that they call artrhocentesis and it made my symptoms twice as bad as they were before. (I agreed to it because I started to lock up mildly a couple of times and it scared me). So I am all for anyone going to pt if their insurance covers it. If not, thats alot of money to come up with for a not so long term releif.
