I am trying out for my high school cheerleading squad but...?

I ABSOLUTELY H-A-T-E MY SMILE. Its not just that I don't like it...its hideous. Im average weight and everything but i have a double chin because of heredity and my actual chin is crooked and has nasty dimples all on it... D': I never smile with my teeth in pictures..not since I was in 4th grade..please help..I have training and training trying to make the cheer team, will I make it even if the judges see that I have a hideous smile? :(
