According to folklore, when children lose a baby tooth, they should place it underneath their pillow and the Tooth Fairy will visit while they are asleep, to take that lost tooth and leave a small payment, especially if those teeth have been kept very clean and shiny. However, what the Tooth Fairy does with the teeth is a mystery. Some say that the Tooth Fairy sends them up into the night sky to become stars, uses them as bricks for their white Tooth Fairy Castle, grinds them to make magical fairy dust for all the fairies, or makes necklaces for all the other fairies. Others believe that the Tooth Fairy keeps the teeth as ornaments that light up her surroundings, especially if they are clean and shiny teeth. Some people believe that the Tooth Fairy recycles the teeth she collects and places them into babies’ gums so they eventually grow teeth, or hands over the baby teeth she collects to dentists who make implants with the teeth to use for people in need. Another theory is that the Tooth Fairy holds great big parties with lots of her fairy friends and hands out the teeth she collects as gifts to her friends. However, it is important to note that these are all just theories and the Tooth Fairys true intentions with the teeth remain a mystery.
