The origins of the tooth fairy varies in numerous cultures, but did you know that most stories actually involve mice? Dating back to the 17th century in France, the origins of the tooth fairy
ties into La Petite Souris, or The Little Mouse.
In the legend, a good queen is imprisoned by a evil king, and enlists the help of a mouse. The mouse, later revealed to be a fairy, frees the queen by knocking out the king’s teeth, later hiding them under his pillow.
It was rumored that if a child lost a baby tooth, and it was found by an animal, the adult teeth would grow back to resemble the teeth of that animal. Since rodent teeth are sharp and strong, families would hope that their children’s human teeth would grow back stronger. Hence, La Petite Souris began.
In other cultures, this legend varies to include beavers, dogs, and even squirrels.
Ancient Myths of Losing Teeth
So, why does the tooth fairy leave money under the pillow? The idea of exchanging a tooth for coins originated in Scandinavia. Vikings believed teeth to be a good luck charm in battle, wearing them on necklaces. When a child lost a tooth, adults would actually pay their children for a lost tooth. Thus beginning the tradition of tooth-for-currency transaction.
The American Tooth Fairy
The Tooth Fairy concept didn’t really take off until after WWII. Similar to how Coca-Cola and Cadbury defined the image of Santa Clause and the Easter Bunny, pop culture helped solidify the image of the Tooth Fairy in American media. In the 1950s, comics and cartoons of fairies ran rampant for American childhood.
