Several patients are speaking out against a Wisconsin dentist who they say drilled their teeth when they didn’t need any work done. Scott Charmoli faces decades in prison following his conviction for healthcare fraud. Prosecutors say he did unnecessary drilling to get the insurance money. At the height of his scam, prosecutors say Charmoli billed more than $4 million for crown procedures. About 100 former patients are now suing the dentist for malpractice and battery.
