My dentist said I may be grinding my teeth at night. I'm not sure if that's true, so I was wondering if theirs a way I could test it. I thought about using my web cam, but I would have to go through 8 hours of video and my web cam is hooked up to my monitor, so I would have to leave my monitor on all night.I don't have a tape recording that could record 8 hours, so what should I do?
