If a child has questions about how the tooth fairy knows when someone loses a tooth, this letter from the tooth fairy can provide some whimsical answers.
Text of the letter:
Dear Susie,
Now that we've done this a few times, you're probably wondering how I always know when you've lost a tooth. The answer is that it's my job to know when a great new tooth is ready to come home with me to my shining tooth castle!
I have a special Tooth Fairy wand that's rainbow-colored. It has a big yellow star on the end of it. When your baby teeth came in, I visited you and tapped each of your teeth with my wand. That helped create the magic spell that keeps my wand connected to your teeth.
Now, whenever your tooth gets loose, my wand flashes blue three times. That's how I know to get ready to visit you soon. When you actually lose a tooth, the star on the end of my wand glows really bright and turns pink. That's how I know that the new tooth is ready and waiting for me to come pick it up!
Your teeth are doing great. I can't wait to visit you again, so make sure you always brush and floss!
Love,
The Tooth Fairy
