When were mouthguards used in rugby?

Mouthguards were first used in Rugby during the early 1900s, with their use becoming more widespread in the 1960s and 1970s as awareness of dental injuries increased. Initially, they were made from rubber or other soft materials, but advancements in technology have led to the development of more effective, custom-fitted mouthguards. Today, mouthguards are considered essential protective gear in rugby to prevent dental injuries and concussions.
