Hey, inpain, have you had a couple of dentists or orthodontists look at your mouth? I had troubles but then found I needed braces when I was 30 years old! The problems (pain and headaches) went away. I was only hitting on 2-3 teeth, had to "corral" my food between them My childhood dentist was an expert but never saw or commented on it and it was only when his replacement, when he was retiring begged me to go see an orthodontist because my bite was off that we discovered the problem.
