I have TMJ in an evil way, too and wear one of those mouth guards. I grind, clench, etc. When it's really bad, I have to take time off chewable food and blenderize everything. If you saw the extent I have ground my teeth you'd be frightened! It's obscenely painful and the sound of me doing it gives me headaches, too. I've gone through periods of virtual lockjaw. And the headaches!!! The neckaches!!! The earaches!!! Seriously, when I say, I have irrepairabley ground my teeth, I'm not joking. My teeth cannot grip food anymore because of TMJ. I hardly have any rear teeth left!
So, in a strange way, my TMJ has forced me to be an herbivore. I basically have no desire to eat chewable food and put it in the blender. Eating even a bowl of cereal is frustrating! I couldn't chew a crust of bread if I tried. I dream of an apple I could bite into! Even chewing a cracker hurts.
TMJ really bites. Thank goodness for food processors because if they didn't exist, I'd vanish.
