The Tooth fairy is not here! HELP!?

Im 18 years old yesterday when i was at baseball practice the ball hit me in the face and my tooth game out! I was so happy, right when i got home i put it under the pillow so the tooth fairy could visit! But, she never came!?!?!!? What happened, does she only give money to people that are under 12? Or did she over douse on drugs or commit suicide? She is one of the most famous fairies in the world, i would be under alot of pressure too.
