Thanks! The way it has been explained to me is during hard collisions, the jaws come together with a great deal of force. This in turn causes the concussion. The mouthpiece acts as a cushion of sorts in softening this collisions between the upper and lower jaw. I'm sure Tari will be able to better explain the medical reasons on how this causes the concussion. Rick [log in to unmask]
