Yup, they are only making me a splint to stop clenching and grinding, not an anterior repositioning splint BUT they X rayed my jaw and I only have a muscular problem.
They are a very reputable dental hospital, although as I said before they do only believe in conservative treatments - not jaw repositioning BUT as I understand it, your jaw took a very hard knock - I don't know what they would do in that situation, maybe they'd prove hopeless, but it's worth a try. I am going to go with their treatment at the moment, and if it doesn't work out for me I will look elsewhere. I know it's really frustrating in England - private dentists are soooo expensive, especially the ones that offer other treatments for tmjd. Sorry I can't be of more help.
