Hi girl, it sounds like you have been through alot. First off, I just want to commend you for working through all of that! Strong Girl! Okay, so let me see what I can make of this. The symptoms you are experiencing are those of TMD, although because of your trauma, you may have other issues as well. I dont know the complete medical history of your accident, but I would like to add that an 8 unit bridge is quite impressing. With as much dental work as you have had, your bite may be off, resulting in what is known as malocclusion. That could have something to do with it. But the big picture is the trauma to the jaw joint and condile. You have a few options. As a temporary fix, you could alternate hot and cold compresses on your jaw joints, and take a regulated daily dose of muscle relaxers. And seeing a chiropractor will help with any back and neck symptoms. While all these help, it is not a permanent fix, and will have to be repeated over and over again. You could have jaw surgery like Tmddyan did. This option is one of the most painful procedures out there. Im sure Tmddyan would probably agree with this. We treat TMD in a different way, using TMD splints. I myself am a TMD patient because I have migraines, clicking and popping in my jawjoints, earaches, stiff neck muscles, backaches, and the worst... lock jaw. Id love to be of any service, if youd like more information, just message me!
