History of Mouthguard Day
Undoubtedly, protective sports equipment did not always exist. Helmets, shin pads, backpacks, and gum shields have evolved — as has the nature of the sport. However, nowadays, the mouthguard is vital as an element protecting sports equipment, which helps prevent damage to the mouth and jaw. The mouthguard gained popularity in America in 1950 and 1960.
Throughout the years, the design and production of mouthguards have improved significantly. The first mouthguards were developed in 1890 by a London dentist, Woolf Krause. It was named a ‘Gum Shield’ and made of a material called ‘gutta-percha.’ It was specifically designed to be worn by boxers to prevent cracking of the lips — which was a common injury in sports at the time. Philip Krause — his son who was also a dentist and amateur boxer — perfected his father’s design and began making a mouthguard out of Vella rubber. By 1927, gum shields had become common among American boxers. A few years later, in 1947, Rodney O. Lilliquist — a dentist from Los Angeles — used clear acrylic resin to create the first acrylic splint, and the kappa was shaped to fit the upper and lower teeth, making it much less visible and more comfortable to wear.
Mouthguard Day, founded by OPRO in 2018, is celebrated on the first Monday in September to coincide with the start of the school year and the start of the new season. OPRO was founded by dentist Dr. Anthony Lovat, who became a witness to children losing their teeth while playing sports due to outfitting or a complete lack of protection.
