Good thing the Tooth Fairy's a generous sort of fairy: 44.6 percent more generous in 2013 compared with the year before, according to a nonscientific email poll of parents conducted by Delta Dental.
The going rate for a lost tooth is $3.50 on average, up from $2.42 in 2012.
The poll, conducted every year since 1998, shows a correlation between the Tooth Fairy's generosity and the performance of the S&P 500. Delta Dental calls it a "good barometer" of the market's overall direction.
