National Tooth Fairy Day is February 28. The small fairy responsible for collecting baby teeth is traditionally depicted as female. In Medieval Europe baby teeth were buried in hopes of growing permanent teeth, according to the University of Florida's Center for Children's Literature and Culture. In the U.S. when a child looses baby teeth, they are instructed to place them under a pillow. In the morning the tooth has been magically replaced with money.
On this day, you can encourage kids to brush and floss, read the child a book about the tooth fairy and replace worn toothbrushes with a new ones.
