A double mouth guard is a mouthguard that protect the upper and lower jaw joint.
The characteristics of a person’s upper and lower jaws are quite different. The lower jaw is capable of a wide range of motion, which means that when a blow lands on the jaw or teeth some of the force of the blow will be buffered by the jaw’s reactive motion.
In contrast the upper jaw is fixed in position meaning that a greater portion of the force of the blow will be directly absorbed by the teeth and jaw bone. This difference, is one of the reasons why a person’s center two upper teeth are the most likely teeth to be damaged by an accident.
In some instances a double mouthguard can be relatively more uncomfortable to wear and therefore an athlete may not use it as consistently as a single mouth guard.
Double mouthguards are recommended for those who have braces and therefore require both lip and cheek protection from their brackets and wires.
When choosing a double mouthguard makes sure that all the back teeth are covered. Some studies have suggested that mouthguards that fail to cover over a significant number of the posterior teeth can place the athlete’s lower jaw at greater risk of fracture.
