A dentist in Virginia was suspended for allegedly having nonconsensual sexual conduct with two patients at his practice while they were under the influence of either alcohol or medication, according to state dental board records.
The Virginia Board of Dentistry issued a summary suspension against Dr. John Alachnowicz of Modern Day Dentistry in Dumfries, concluding that “a substantial danger to public health or safety” warranted this decision, according to a state order dated June 24.
“It is further ordered that a hearing be convened within a reasonable time of the date of entry of this order to receive and act upon evidence in this matter,” according to the state order.
On November 25, 2025, a female patient went to Alachnowicz’s practice for a tooth restoration. During the appointment, Alachnowicz allegedly locked the doors, turned off the lights, and put the office phones on “night mode.”
At the end of the appointment, he allegedly plied the woman, who had been a patient since 2014, with alcohol and then engaged in nonconsensual sexual conduct, including groping and penetration, according to the state.
Alachnowicz’s girlfriend, who also worked at the practice, confronted him about the conduct and threatened to report him. The girlfriend recorded their conversation during which Alachnowicz purportedly acknowledged that her reporting the incident could cost him his license and send him to jail, according to the state records.
In January 2026, his girlfriend told an investigator that Alachnowicz allegedly had unprotected sex in the practice with a man he met on an online dating app. Worried about her health, the girlfriend allegedly told Alachnowicz never to touch her again, according to the state records.
Despite what she said, in October 2023, Alachnowicz allegedly engaged in nonsexual conduct with his girlfriend during a dental procedure while she was under the influence of Ativan and nitrous oxide. The girlfriend reported to the investigator that she discovered a video that Alachnowicz took of the assault. When she confronted him about it, Alachnowicz admitted to it, according to state records.
During their recorded conversation, Alachnowicz admitted to multiple "nitrous episodes" while engaging in sexual conduct, and absent a "legitimate dental purpose." Additionally, it was revealed that he allegedly improperly prescribed her the Ativan, according to the state.
Also, the girlfriend told the investigator that Alachnowicz allegedly admitted to self-administering nitrous oxide at the practice for his own sexual gratification.
A criminal complaint is merely an allegation. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
