hey, i enjoy boxing sometimes with other team mates. but i have a under-bite (lower jaw sticks out farther then upper jaw) do i wear the mouth-guard on my bottom or upper jaw? i currently use the boil and bite shock-doctor mouth-guard , i don't know how the quality compares with the other brands. i currently wear it on my upper teeth which leaves the bottom teeth for damage... every time i box i would always stress out about my teeth and check in the mirror if all the teeth are still in proper shape. so should i wear the mouth-guard on my bottom or upper teeth? and does having a under-bite mean i'm more acceptable to getting knocked out easier? thanks for the help i appreciate it.
