The SmartGuard is the "Best" TMJ OTC night Guard to reduce TMJ symptoms available. In fact, it is out performing custom night guards made from Dentists.
If you have headaches, statistically this guard should reduce 77% of headaches out of 82% of headache sufferers. This is my highest recommendation out of all OTC night guards available.
