Guard Your Mouth

I got my new mouthguard from the dentist just a moment ago. It seems I grind my teeth hardcore when I sleep (actually, I know I do, I sometimes wake myself up with how hard I grind), and that could account for the neck pain, upper back pain and headaches I get so often. I’m not sure how sleeping with this rubber mold in my mouth will be, but if it helps, so be it.
