I agree, however at one time it was accepted that wearing of mouth guards did reduce concussions. I heard it all the time during the 90's playing higher level rugby.
In fact 2 years ago at a coaches meeting for lacrosse I heard the same thing. A member of Red Deer Lacrosse stipulated that all kids needed to wear mouth guards to avoid concussion. When I questioned her, she could not respond.
I would suggest that the opinion on mouth guards and what they do regarding concussions is misunderstood by many in the populace.
