According to various sources, the Tooth Fairy is a secretive magical creature that collects childrens baby teeth when they fall out and leaves a small payment in exchange. However, what the Tooth Fairy does with the teeth is a mystery. Here are some of the most common beliefs:

• Turn them into fairy dust: The Tooth Fairy grinds down the teeth to make magical fairy dust for all the fairies.
• Use them as building materials: The Tooth Fairy uses the teeth as bricks for their white Tooth Fairy Castle.
• Make jewelry: The Tooth Fairy makes necklaces for all the other fairies.
• Send them to dentists: The Tooth Fairy hands over the baby teeth she collects to dentists who make implants with the teeth to use for people in need.
• Plant them in babies gums: The Tooth Fairy recycles the teeth she collects and places them into babies’ gums so they eventually grow teeth.
• Keep them as ornaments: The Tooth Fairy is fascinated with teeth and keeps them with her in her castle as ornaments that light up her surroundings, especially if they are clean and shiny teeth.

Its important to note that these are all just beliefs and there is no concrete evidence to support any of them. The Tooth Fairys activities remain a mystery, and its possible that the Tooth Fairy herself doesnt even know what she does with the teeth.
