The company said the average tooth fairy payment was about 34 cents 25 years ago, but has jumped in the past generation to an average of $2.10, The Scotsman reported Tuesday.
The study found the current average could earn a child who loses 20 teeth between the ages of 6 and 11 -- roughly one in 12 children -- more than $80. The 500 percent inflation rate contrasts with the 150 percent rise in the cost of living over the same time period and resembles the 600 percent rise in house prices.
"The generosity of the tooth fairy has accelerated rapidly and shows no signs of abating," said David White, chief executive of The Children's Mutual. "Teaching the value of money is often difficult, but the tooth fairy is on hand to help. Paying children for lost teeth could help bring playing shop and money games to life."
