Is there any home remedy for teeth grinding besides a mouth guard?

Orthopedic Dentist: The cause of grinding is rarely correctly treated. Most dentist make a bite appliance for you to wear to keep from grinding away the teeth. This is only treating the symptom and not the cause. The usual cause is the roof of your mouth (palate) is too narrow in comparison to the lower jaw. The muscles not finding their home position keep searching = bruxism results.

Relaxation: Often, teeth grinding is a subconscious release of daily tension/stress. If you can reduce your stress and especially before bedtime (like: do not watch tv news before going to sleep). Try to either watch a comedy on tv or read something light ( not work related) and see if this helps. Some are helped by exercise or yoga.
