Your dentist can give you a night guard to protect your teeth while you are finding a more permanent solution to the problem. And of course, there’s an app or two for that. The Hypnosis App for Teeth Grinding by Open Hearts is a 30-minute session for relaxation and hypnosis at home. Do I Grind, another app that is due out this summer and will record and rate the severity of your grinding while you sleep. It will also help you determine possible triggers.
