NEW YORK ( TheStreet) -- Bad news for America's kids.
Visa's (V) sixth annual Tooth Fairy survey found that families are paying less per lost tooth for the third consecutive year.
Payouts per tooth dropped to $3.19, slumping 24% from 2014.
The average American child can now expect royalties of only $64 for their entire under-the-pillow collection, down from $74 two years ago.
The Visa survey highlighted other trends.
Dads are the more generous tooth fairies on average for the second year running, paying $3.63 per tooth, while moms averaged $2.87 per tooth.
Tooth prices also varied by location.
Kids in the Northeast of the country racked up $3.56 on average, while Southern kids were paid the least, cashing in only $3.07 per tooth.
A dollar bill was still the most popular amount left by the tooth fairy, favored by 32% of the parents surveyed, while only 5% of respondents gave $20 or over.
Back in 2010, Forbes calculated the Tooth Fairy's net worth to be around $3.9 billion, ranking 8th on the list of richest fictional characters.
"The Tooth Fairy is finally fluttering back to earth," said Nat Sillin, Visa's director of global financial education, adding, "No matter how much is left under the pillow, a visit from the Tooth Fairy is an ideal opportunity to talk with children about the importance of saving and budgeting."
The credit card giant surveyed parents from more than 4 thousand families across the U.S. from different locations, ages and income brackets.
In the survey's six-year history, 2013 seems to have been the most lucrative year for wobbly teeth
The financial benefits of the tooth fairy still seem to be available for the majority of kids, according to Visa, with only 1 in 10 receiving nothing for a lost tooth.
