Investigators believe John Szewczyk. 45, owned the business and paid bills while assisting his wife in managing the office. Krista Szewczyk, 47, allegedly pulled teeth, applied fillings, replaced crowns and wrote prescriptions for pain medications in the dental office. But she has no medical license and isn’t even a dental hygienist, records show.

Additionally, the pair is accused of billing insurance companies as though a licensed doctor performed the procedures, the indictment states. Insurance claims were also allegedly submitted for dental work that was never done.

On Aug. 23, Krista Szewczyk was arrested after a Paulding grand jury indicted her on 48 counts, including 40 counts of practicing dentistry without a license, three counts of writing unlawful prescriptions, one count of forgery and three counts of insurance fraud. Two weeks later, Szewczyk was arrested in Cobb, where Marietta police also believe she performed dental work.

As early as 2012, Krista Szewczyk was performing illegal work on the mouths of customers, according to her previous indictment. She was accused of posing as a dentist, but at that time, her husband was a Paulding sheriff’s deputy, and the DA’s office there determined it was a conflict of interest to pursue the charges. Instead, Szewczyk was offered a pre-trial diversion program, the DA’s office previously said.

But investigators allege Krista Szewczyk continued to run her practice. She later closed the Paulding office and re-opened in Marietta.

The Georgia Board of Dentistry, whose prime responsibility is protecting dental patients, knew by at least 2014 that Szewczyk may have been violating the law, according to an investigation by The Atlanta Journal-Constitution. But rather than issue a cease and desist order and impose fines, as the board has done nearly four dozen times in similar cases since 2000, the board referred the case to prosecutors.
