Wisconsin dentist Scott Charmoli performed more than $2 million worth of crown procedures between January 2018 and August 2019.
But according to Newser, the 60-year-old used his drill to break off parts of his patients' teeth so he could justify the dental work.
Charmoli was charged Tuesday in federal court with eight counts of health care fraud and two counts of false statements.
The indictment says Charmoli submitted images of the chipped teeth to insurance companies to obtain coverage for the crowns.
He faces a maximum sentence of 20 years in prison and a $250,000 fine if convicted.
