Lynn's Comments: Every now and then I could work in a "public service announcement" thanks to our in-house dentist. Grinding your teeth at night is something many of us do without being aware of it. You can even crack a filling with the strength of your jaw. A "bite splint" will help to relax your jaws at night and keep you from having that awful head-achy feeling in the morning. Sadly, it can't help to solve the problems that make you grind your teeth in the first place!
