At our house, when you lose your first tooth, the Tooth Fairy brings you something special to keep your teeth in. She/he also leaves you a note about taking care of your teeth. My son got a Fang Dangle (http://www.etsy.com/shop/lilypadworkshop?section_id=6264395) just recently. Each child has their own special fairy also, so that's why sometimes fairies do different things or say different things to each child.
The Tooth Fairy brings you $3 for your very first tooth and $1 for teeth after that. And she doesn't give you as much money for teeth that have fillings, because she uses the old teeth to make new teeth for babies who will need them. (Reduce, reuse, recycle, right?)
