New Sizing System

Research suggests the taller you are, the larger your dental arch. And Thus, a bigger mouthguard is required as height increases. Our new and improved sizing system uses the findings of extensive research and testing to suggest the proper guard for you based on how you measure up.

The Science of SISU

In our labs, we have put each mouthguard through strenuous testing to see how it performs in relation to its competitors. SISU Guards are made from unique medical grade thermo-polymer, which is, remarkably enough, free of harmful chemicals. SISU material is non-compressible, which enables SISU Guards to outperform the competition in tensile strength tests.

The tensile strength of our SISU material is consistently at least 30% higher than the that of conventional EVA material used by most other mouthguards. Due to its built-in Diffusix™ Technology, SISU better protects your teeth from damage. Learn more about the Science of SISU.


Powered by our patented Diffusix™ Technology and engineered to withstand even more impact, SISU Mouthguards deliver unprecedented protection with its scientifically designed perforation pattern. Based on suspension bridge technology, the main function of the perforations is to redirect the forces of impact. On impact, perforations oscillate and send the forces into our scientifically engineered Crumple Zones - the reinforced points of the guard that don’t cave in under pressure. Here, the force of impact is redirected away from teeth and absorbed into the non-compressible surface of the guard. This unique design empowers SISU Mouthguards to protect you from even the toughest hits.


Custom fit, remoldable SISU Mouthguards feature a wide bite pad, rounded edges and a perforation alignment which enables the maximum dissipation of force transmitted from the point of impact. Superior protection is not the only function of the perforations. They also allow for flexibility in the material for a better mold to create an intimate custom fit, so unique to the player’s mouth that the guard can remain inserted during the entire game or practice. Additionally, perforations allow for natural flow of air and saliva to empower athletes to talk normally, breathe naturally and stay hydrated during the game.
