SISU Mouth Guards (formerly known as "ProTech Dent") The SISU Mouth Guard is made from a non-compressible, perforated material. It has unique impact-energy absorbing perforations and special "crumple zones" directing impact forces away from teeth. Plus, it dissipates the impact energy over larger areas. The SISU Mouth Guards feature: Adult-sized mouth guards are made to fit ages 11+ The guards provide 30% better protection than conventional mouth guards, despite being only a sleek 1.6mm thick The mouth guard is preforated, so you"ll drool less Snug fit lets you easily breathe, talk, and drink Helps limit the spread of nasty germs because you"ll actually keep it in your mouth throughout practice rather than removing it to speak, drink, or breathe! Got braces? You can absolutely fit the SISU Mouth Guard with braces. However, we strongly advice you to take the mouth guard to your orthodontist or your dentist to get professional help in getting the best fit. He or she will use some kind of barrier against the brackets so that the material, while pliable, doesn?t bond to your braces.
