Follow-Up: I myself am also curious. I am twentyone years old and it's so bad I'm terrified to go to sleep at night. I wear a mouth guard but I have still managed to crack four teeth totally in half, and I completely crushed all four of my wisdom teeth, I woke up spitting out little chunks of teeth, lovely eh? I set my alarm so that I can only sleep for 45 minutes at a time, on average I sleep and hour and a half to two hours a night. I know nothing about it I just searched for jaw grind and got this page. If anyone could has some advice I could really use it! Thanks.
