Born from co-founder Bobbie Quinn’s son suffering a hockey concussion, Gladiator Guards makes custom-fit mouthguards that athletes can order without a dental visit. Founded in 2001, the Philadelphia-based company builds each high-heat, multilaminated Gladiator from an impression of the athlete’s teeth, using 3D scanning and lifetime digital impression storage to support future reorders. Its custom guards are personalized with team logos, colors and player identification.
