Bring on the Fairy

Eloise's incisor has been wobbling for months. Ever since she stacked it in the playground and face-butted a wooden platform.

The wobble has increased as time has gone by and for weeks now the tooth has been hanging by a thread. She's been wibbling it with her tongue and twisting it around but it has held on for dear life.

Until this evening, when it finally let go.

What's the going rate for the Tooth Fairy?
