Kids who want to keep the teeth they lose can use this printable letter template to ask the tooth fairy not to visit.
Text of the letter:
Dear Tooth Fairy,
I lost one of my teeth the other day, and I am writing to ask you to please NOT visit my house. I would like to have my tooth as a keepsake instead of sending it off with you.
Thank you for offering to take my tooth and leave me a present, but I don't want to do that this time. I will write you another letter if or when I'd like you to come to my house. Otherwise, I'd like to keep all the teeth I lose from here on out.
Thank you for understanding, and I hope that your fairy castle has a lot of teeth from other kids that are good for building.
