For hundreds of years, mystical legends, stories, and traditions have been shared about the loss of baby teeth. In some cultures, children’s teeth were buried in order to hide them from witches and evil spirits who would use the tooth’s powers for voodoo. The Vikings believed that children’s teeth had a magical power in them that would help them fight in battle. They would even pay their children for their lost baby teeth so that they could be used to string onto battle necklaces and other jewelry.
Over time, people began to share stories about a Tooth Mouse who would scamper around town and steal children’s teeth in the middle of the night. This story of the mouse soon transformed into the story of the Tooth Fairy, who would leave treasures under the children’s pillows in exchange for their lost teeth.
The traditions and legend of the Tooth Fairy are still practiced today all around the world. It is considered a useful practice by many parents because it gives their children something to look forward to when they lose their teeth. And so year after year, baby teeth are placed under children’s pillows at night in hopes of waking up to a wonderful surprise from none other than the Tooth Fairy.( http://www.toothfairy.org/2012/01/04/hello-world/)
