Mouthguards provide protection to the athlete in three different ways. Mouthguards protect against concussions by serving as a shock absorber, they protect against neck injuries, and they protect the teeth by distributing the force of a blow over all the teeth and diminishing contact between the mandible (lower jaw) and the maxilla (upper jaw). The most important function of the mouthguard is in the prevention of concussions and brain injuries (Witzig, 1992). A mouthguard with the proper thickness of 3 to 5 mm between the teeth can reduce the rate of concussion by preventing the condyle (lower jaw hinge) from being forced into the base of the brain (temporal bone) at impact. Ninety five percent of all football concussions are transmitted through the mandible to the brain (Witzig, 1992). The use of mouthguards should be encouraged in all contact sports as the most important value of the mouthguard is the concussion saving effect following impact to the mandible (Stenger, 1964).
