An Alaskan dentist who extracted a patient’s tooth while on a hoverboard was sentenced Monday to 12 years in prison for dozens of charges including Medicaid fraud, the Anchorage Daily News reported.

Anchorage Court Judge Michael Wolverton said Monday that Seth Lookhart nearly killed several patients by frequently sedating them for extended periods of time.

Lookhart was found guilty by a jury in January on 46 charges including Medicaid fraud, embezzlement, reckless endangerment, and unlawful dental acts. He formerly worked at Alaska Dental Arts in 2015 but later bought the business and changed its name to Clear Creek Dental.

Charges against Lookhart were filed in 2017 after a former employee told investigators the dentist was increasing profits by performing more sedation procedures than necessary. In 2016, Lookhart and his former office manager Shauna Cranford billed nearly $2 million in unjustified sedation expenses, the Anchorage Daily News reported.

During the trial that began last November, former employees and patients testified against Lookhart, including a woman whose tooth was pulled while Lookhart rode on a hoverboard.

In the viral hoverboard video, Lookhart balanced on the board while extracting a patient's tooth before zooming away into the corridor. 

Investigators tracked down the patient, Veronica Wilhelm, who was sedated and had no idea about the hoverboard stunt, the New York Post noted. 

She testified in court last year that she was upset when she discovered what had happened. 

"When did Dr. Lookhart get your approval to take out your tooth on a hoverboard?" prosecutor Joan Wilson asked in court.

"He never did. I obviously wouldn't have approved that. That's dangerous," Wilhelm said. 

Another patient testified about having four teeth removed without his permission.

Lookhart’s dental license was suspended in 2017 after the charges were filed, but Wolverton ruled Monday that Lookhart will not be allowed to practice medicine during his 10-year probation period. 

Prosecutors on Monday asked Wolverton to order Lookhart to pay $2.2 million in restitution for the fraud and embezzlement, although the amount will be determined at a hearing later this month.
