They’re not fresh. The fairy demands the freshest teeth but long ago ancient humans made a pact with the tooth fairy. In exchange for humanity to cease its hunt of the tooth fairy, the TF will stop hunting children in their sleep to pursue the freshest and most desirable teeth. Centuries later, with the advent of capitalism, the humans rebelled and demanded compensation for the teeth to be given to the children. The TF, seeing the advancement of human warfare capacity quickly agreed to a small stipend per child in order to continue its harvesting.
The fae operate on a different set of rules. The Tooth Fairy can only take teeth that are freely offered. The dead cannot consent.
The tooth fairy only wants children’s teeth. Have you checked any child graves recently for teeth?
How else am I supposed to get some change?
My favorite tale is that the rat king takes the teeth. He trades in secrets which are stored in the teeth and children have an uncanny ability to over hear things that not even rats can learn, so he pays the children based off the quality of the secrets. You also can’t lie because lies damage the teeth and the rat king won’t pay as much.
They eat the teeth. You gonna dig up a decades old deer corpse and eat it?
$20 is $20
