Sounds like The Tooth Fairy is on a bit of a budget! Kids aren't getting quite as much money for their lost teeth these days. Delta Dental conducted a poll, and found that children get an average of $3.70 per tooth, that's a drop of 43-cents from last year! Boy, and I thought this was a good economy. Lots of parents (um, I mean Tooth Fairies) still fork over $5 per bicuspid, incisor or molar. 46% say how much money the Tooth Fairy leaves depends on how much money she has in her little sparkly purse. How much money does the Tooth Fairy leave under your child's pillow?
