When I was going up for a head ball in soccer, jumped up and flung his elbow around, and my tooth went through my lip.... To tell you the truth I really didn't feel it. After my coach put a bandaid... he said I could play again if I wanted... when I say a bandaid I mean like the kind that you use on paper cut....not a hole in your lip... Well, anyway, I finished playing the game, and the hole closed up in about a week. Other than that, I've been able to avoid breaking anything else....besides my toe from kicking a ball the wrong way...
