So in my country we have the thoot fairy but we don't to anything with it in our family. I have lost very few teeth for the age of 12. So far I have lost 10 maybe. I am collecting them ;)
I have lost 1 tooth because it fall down. Then I put it under my pillow and a tooth fairy came! And at last, she gave me a silver coin.
I have lost 10 teeth. In my country there is not a tooth fairy, but a little mouse who takes the tooth that you have put under your cushion.
