Jaw anteriorly dislocated And distorted disc on left

My wife has a dislocated jaw!!
She believes it was caused by a small bite splint her dentist gave her because he said she was grinding her teeth. She has since found this not to be true. she does not grind her teeth. She was told by her dentist to wear the splint 24-7 to which she complied. At first she had severe head aches caused by the splint and when she complained the dentist prescribed a pain killer for her. He said the headaches would go away.
They did go away in about two weeks so she continued to wear the splint.
In about four months she noticed that she no longer had and overbite which she has always had. Within hours after observing the overbite was gone her jaw dislocated when she yawned. She has been living a nightmare ever since. It has been just over a year and a month now and she still has severe headaches, ear and jaw pain, and neck and shoulder pain.
We have been to two oral surgeons, several dentists, one dentist has made her another full bite splint that has helped with the pain part of the time. He has readjusted this splint at least 50 times in the past year.
The original dentist never called her in at any time from the time he put the small bite splint in until now. It was like he hoped she would go away and never come back. He will get his wish unless I can find someone with the same problem so I can go after him so he can live the same nightmare hopefully for the rest of his life.
Real nice guy. It was all just for the money.
Please if anyone has had the same or similar problem please respond.
