The National Hockey League is the only sport with such a group. Only 60% of NHL players wear mouth guards, even though helmets are mandated. Odd, considering sports like field hockey and women's lacrosse have long mandated mouth guards even while fighting efforts to require eye protection or helmets.
Many teams have a dental office attached to their locker room now, completely equipped for any contingency.
When Gordie Howe broke in with the Detroit Red Wings in 1946, he scored a goal and lost four teeth in his first game. He didn't not lose another tooth in a career that ended 34 years later. "I learned to play religious hockey," Howe liked to say. "It's better to give than receive."
NHL players refer to dental damage as "spittin Chiclets."
