Smart mouth guard tells users if they're grinding their teeth
Bruxism – or "tooth-grinding" to most of us – is a very common problem. Often caused by stress, it can cause tooth damage, headaches, insomnia and jaw pain. Unfortunately, because it occurs when we're sleeping, many people don't even realize they're doing it. Often, a night spent under observation at a sleep clinic is the only way of "catching it in action." That could be about to change, however, thanks to the development of a bruxism-detecting mouth guard.
