I have been considering getting an NTI for clenching my teeth. It is a small clear plastic device the dentist fits to keep your front teeth from touching, then the rest can't touch either. I did some research and wanted to share with you who have migraines. About 80% of these devices are being used with success in curing migraines you wake up with. They are called NTI: NOCICPTIVE TRIGEMINAL INHIBITION DEVICE.
