The legends go back thousands of years, and the fairy in Western culture has appears in many shapes and sizes, young and old, human to spirte and even animals and birds have inspired the look of the tooth fairy.
The folklore says that when you lose one of your baby teeth, you should place it underneath your pillow and the tooth fairy will visit whilst you are sleeping, take the tooth and leave you some money in return.
It's believed that the tradition of the tooth fairy started around 1900, according to Peter Navarez. There's a tradition from Lancashire that children should brush their teeth and take care of them, or they'd be visited by 'Jenny Greenteeth', who hangs around ponds. She was a sort of fairy-like figure, but perhaps more of a hag, or witch.
The tooth fairy idea did not appear much in literature at that time, and was more of a oral history tradition, although today she is a popular tradition with children and parents, and a great way to get children realising the importance of looking after their teeth.
