The Friday File: The number of wisdom teeth removed in the US is 10,000,000/year! And with generally two teeth extracted at a time, that means 5,000,000 surgeries. At an average cost of $500/exodontia, that adds up to $5 billion/year. Separately, adults with at least one original tooth currently have a mean of 25.5 original teeth, up from 25 in 2000. A full set of adult teeth excluding wisdoms is 28.
