The Tooth Fairy is a wonderful, and well loved figure from all our childhoods.  Traditionally, most children believe that when they lose one of the baby teeth, they can place it underneath their pillow and the Tooth Fairy will come to collect it whilst they sleep.  The tooth is generally replaced with some kind of small payment from the fairy, be it money, a small charm or some other treasure like a crystal or gift.  The Tooth Fairy almost always leaves a small trail of fairy dust behind, or perhaps even a tiny footprint or two!
