tooth fairy

The Tooth Fairy is a mythical character depicted as a fairy that gives a child money in exchange for a baby tooth that has fallen out. Children typically place the tooth under their pillow at night while they sleep. The fairy is said to take the tooth from under the pillow and replace it with money. early Europe, there was a tradition to bury baby teeth that fell out.[2] 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.In some Asian countries, such as India, Korea and Vietnam, when a child loses a tooth the usual custom is that he or she should throw it onto the 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. This tradition is based on the fact that the teeth of mice go on growing for their whole life, a characteristic of all rodents.
In parts of India, young children offer their discarded baby tooth to the sun, sometimes wrapped in a tiny rag of cotton turf.
