Dude you need to fix the jaw if you ever want to be better.
Your strongest medicine is getting rid of the root canal and silver in mouth. Find a biological dentist and get it done. If you cant find one then google Hal huggins and ask him if he knows one in you area. You want a biolgocial dentist to remove the mercury from mouth-needs to be done correctly-very important. Everything else everybody wrote is good supportive care-do all of that-but most important is dental is you want a possible cure
