The Shock Doctor Gravity mouthguard is unique in that it is fitted for the lower teeth to allow for unrestricted breathing and more natural speaking. This revolutionary mouthguard was designed specifically to be worn with a helmet and cage providing all the benefits of a traditional upper mouthguard including jaw-joint and concussion protection (provided that it is worn in conjunction with the helmet and cage). The Central Fit Slot of the mouthguard provides a low profile fit while the lateral jaw stabilizers protect the lower jaw from side impacts. Fully customizable (just boil in water and bite) for all adult mouths. Not for use with braces.

Also featuring MORA Performance Enhancement: When fitted and worn correctly, the Shock Doctor Ultra Mouthguard positions the lower jaw down and forward, and the tongue up into the roof of the mouth (MORA position) which may increase strength and athletic performance.
