The Tooth Fairy is a mythical figure in many cultures, particularly in the United States, who is said to visit children when they lose their baby teeth. Traditionally, children place their lost teeth under their pillows at night, and in exchange, the Tooth Fairy leaves a small gift or money. This practice helps make the experience of losing teeth more enjoyable for children. The origins of the Tooth Fairy can be traced back to various traditions surrounding the loss of baby teeth. In some cultures, teeth were buried or burned to protect children from misfortune. The Tooth Fairy has become a popular symbol of childhood and the transition to adulthood.
