Not many people wear a mouthpiece in ball hockey, but I’ve been hit in the mouth before and I will tell you it’s not fun. When I looked into mouthpieces in 2017, I wanted something low-profile that wouldn’t hinder my communication on the rink. I found the SISU brand and purchased their Aero Guard. It comes completely flat and you mold it to fit your teeth. It’s pretty amazing, to be honest.
