"This dentist never should have been paid in the first place," State Comptroller Thomas DiNapoli told the New York Post. "Human beings typically have 32 teeth. When a dentist tries to get paid for filling 52 teeth in one mouth in one day, it should raise some red flags."

The dentist, who practices in Brooklyn and lives on Long Island, is under investigation by the state Education Department, which is in charge of licensing for dentists and says it first learned of the dubious fillings from The Post, and the Health Department, which supervises Medicaid.

"We're looking at every dollar he's ever submitted through Medicaid," a Health Department spokeswoman said.

The dentist reportedly billed Medicaid for work on two other patients the same day that he billed for the 52 fillings.

The dentist's wife told the Post that her husband has been practicing in the United States for 30 years with no legal problems.
