What does the tooth fairy do with all those children’s teeth ?

Sorry to do this but...

Baby rattles

Right now she is building her weekend home with them.

Makes a giant pool like with scrooge mcducks money pit to jump into?

Scrimshaw -- very delicate scrimshaw.

Contains bad language.

Not sure but my father saved some of mine and had them in his jewelry box thing. He died and my stepmother never mailed them to me. 😉

there's a discworld book about that. whatever it could be, it'd have to be disturbing.

Crafts them into small humanoid figures for companionship

They turn it into toothpaste.

Sells them to denture manufacturers

On teen titans go he ate them...

Omg. My daughter has one under her pillow right now. Last one she lost I only had a $5 bill and so I gave her that.

Today she says "I wonder how much dollars I will get this time from the tooth fairy?"

I was thinking: this time the tooth fairy is taking taxes for the last time!

What did artists use to do with ivory when it was legal?
