My mouth lock was caused by grinding/clenching at night (over a period of time). I also clench in the day. I was fine one day & then that evening out of the blue my mouth locked up. I don't know why it happened at that particular time. I had really sore back molars and a headache for a few days after the lock, but really no pain in the actual jaw joints- I just can't make it open further.
The dentist did some more jaw manipulation since my last post- he did a fair bit of pressure on the jaw this time, but really no improvement with the opening. He gave me a little thing that keeps my teeth from coming together, which I think helps stop me doing further damage. Overall from taking the muscle relaxants & the jaw manipulation my mouth opening has only improved by 1-4mm at best, to a total opening of around 3cm. My jaw is a little bit tender at the moment from the manipulation, but not too painful
. He said that as a dentist there's nothing he can do with the mouth opening, so I've been referred to a jaw surgeon. Not for surgery though, but just some other alternatives & for a second opinion. The jaw discs have apparently been pushed forward & won't go back.
I really don't know what to do...I don't know if it's best to just leave my jaw alone & it will heal itself or see the specialist? The dentist seemed to think these things don't heal by themselves. I'm grateful I can eat still mushy foods & at least can talk, I'm scared things will get worse if I mess with my jaw too much.....
