Tooth fairy economics is just a playful name for how differently every family handles a lost tooth.

In kid words

"What the tooth fairy leaves is a surprise, and every family does it a little differently, so there's no exact right answer." What matters most is the gap in your smile and the story of how it happened. That is the part worth telling again and again, long after the tooth itself is forgotten.

The parent version

Tooth fairy economics is not a real economic term, just a lighthearted way people describe how widely families vary in the way they mark a lost tooth. There is no standard practice and no single right way to do it. Some families write a note, some leave a small memento, some simply make a fuss out loud at breakfast, and plenty do all three at different times.

Whatever tradition, if any, your family keeps is entirely your own to decide, and there is no need to compare notes with another family's version. The part that tends to matter most to a child is simpler than any of it: being told plainly that losing a tooth is something worth celebrating.

Where you might hear it at our office

A loose tooth finally letting go is exactly the kind of thing that can come up at a routine cleaning and exam, especially if a parent is not quite sure whether it is really ready or just being wiggled early. Your pediatric dentist can tell you what they see and whether it is worth waiting out a little longer.

Storybook Reef keeps a free story about a wiggly tooth finally coming out, along with a printable certificate for marking the occasion, both waiting at our storybooks page. And if today's visit left another word rattling around, the Kids' Dental Dictionary has the rest of them.
