Older Customs Behind a New Figure

Medieval Norse custom documents an actual historical payment called tand-fe, tooth fee, a small gift given to a child at the emergence of their first tooth, recorded in Old Norse sources as an established practice, which folklorists treat as one of the clearest documented antecedents feeding into the much later idea of a reward specifically tied to teeth.

Other European cultures developed their own distinct custodian figures for lost teeth rather than a fairy: French and Spanish speaking children traditionally leave a tooth for a mouse rather than a fairy, La Petite Souris in France and El Raton Perez, or Ratoncito Perez, in Spain and much of Latin America, a mouse who takes the tooth and leaves a small gift in its place, a parallel tradition with its own separate literary history rather than a variant of the same fairy figure. The tooth fairy proper is best understood as the American form of a much wider and older cross-cultural pattern of ritualized attention to a child's lost teeth, a pattern responding to a genuine and recurring feature of childhood that different cultures addressed with different imagined agents and different underlying concerns, protective anxiety in the older European customs, festive reward in the modern American one.
