toothfairy legend

In early Europe, there was a tradition to bury baby teeth that fell out. Some believe that the Tooth Fairy evolved from the tooth mouse depicted in an 18th century French language fairy tale. In "La Bonne Petite Souris," a mouse changes into a fairy to help a good queen defeat an evil king by hiding under his pillow to torture him and knocking out all his teeth.
This combination of ancient international traditions has evolved into one that is distinct Anglo-Saxon and Latin American cultures among others.
The "Ratoncito Pérez" character was created around 1894 by the priest Luis Coloma (1851–1915), a member of the Real Academia Españolasince 1908. The Crown asked Coloma to write a tale for the eight-year old Alfonso XIII, as one of his teeth had fallen out. In Italy also the Tooth Fairy (Fatina) is often substituted by a small mouse (topino).roof if it came from the lower jaw, or into the space beneath the floor if it came from the upper jaw. While doing this, the child shouts a request for the tooth to be replaced with the tooth of a mouse.
