Hendriks wore his GuardLab ARC™ Lower Performance mouthguard all season and when he closed out the National League to seal the win of the 2021 MLB All Star game for the American League.   


“I was first introduced to GuardLab’s custom mouthguards back in 2015 and immediately noticed the benefits to my performance. I wear my GuardLab custom fitted lower mouthguard during games and while practicing, not only for its comfort, but also for its tension relief and benefits to my breathing,” said Liam Hendriks. “I am a passionate believer in performance, quality and design and I’ve found that with GuardLab. I’m looking forward to joining the GuardLab team.”


GuardLab’s ARC Technology, an acronym for “Alignment Repositioning Cushion” is a patented neuromuscular mouth guard that uses 3D Technology to accurately measure an individual’s bite to help stabilize the jaw and surrounding muscles, improve oxygenation and reduce TMJ tension.

To see him share his passion for GuardLab with other athletes, especially the younger athletes, we hope he will inspire others to consider the benefits of wearing a mouthguard. Having an elite MLB athlete as Liam, as a wearer and believer in GuardLab technology, speaks to our unparalleled quality and supports our vision to make better fitting and better performing mouthguards for every type of sport and every level of play.”
