number three has come out!! when she leaves her tooth under her pillow, her tooth fairy comes and takes it back to the gnomes. they love childrens' teeth as they help the crystals grow bigger and brighter. in exchange for her tooth, the fairy brings a crystal back from the gnomes' cave and tucks it into her tooth pillow.
she says that each child has their own tooth fairy. your tooth fairy is always with you until you are all grown up and you have stopped losing your teeth. then your fairy finds a new little child to look after but is always nearby if you need them. so sweet!
