A 70-year-old woman from Long Island is at the center of a troubling case that has raised serious concerns about public health and safety.
Gladys Serrano, a Hempstead resident, allegedly transformed her one-bedroom apartment on Greenwich Street into an unauthorized dental office.
According to the Nassau County District Attorney’s Office, Serrano performed dental procedures without a license, endangering the health of at least one identified victim—and potentially more.
The alleged operation first came to light following a harrowing incident involving a trusting patient.
The victim, whose identity has not been disclosed, reached out to Serrano through a referral to arrange the extraction of a single tooth.

What began as a seemingly straightforward procedure quickly spiraled into a nightmare.
On July 26, the victim arrived at Serrano’s makeshift dental office, where a hanging curtain divided the kitchen from the rest of the apartment. Serrano informed her that she actually needed five teeth removed, citing severe decay.
The victim, relying on Serrano’s guidance, consented to the procedure. Prosecutors allege that Serrano extracted the teeth, provided the victim with paper towels to manage heavy bleeding, and instructed her to rinse with salt water as a follow-up treatment.

The victim’s ordeal did not end there. Serrano recommended a dental bridge to replace the extracted teeth, prompting the victim to make multiple return visits between August 16 and December 4.
Over these months, Serrano charged the victim a total of $1,950, according to the DA’s office.
Despite paying nearly $2,000, the victim never received a bridge that fit properly. Serrano reportedly took additional molds of the victim’s mouth and filed down impressions, but her efforts failed to produce a satisfactory result.
The alleged operation came to the attention of law enforcement, leading investigators to search Serrano’s apartment. What they discovered painted a chilling picture.

The kitchen-turned-dental-office featured a patient chair positioned near a sink and drawers filled with apparently used dental instruments.
Investigators also found impression molds, extraction tools, tartar scrapers, and a large container brimming with empty medication vials and used dental needles.
Boxes labeled as single-use dental needles, capsules of antibiotics like Amoxicillin, the anti-inflammatory drug Relaflex, and the local anesthetic Lidocaine were also recovered.
A search of New York State records revealed no evidence that anyone named Gladys Serrano is licensed to practice dentistry. This crucial finding underscores the gravity of the allegations.

“Practicing dentistry without proper authorization poses an incredibly serious risk to public health and safety,” stated Nassau County District Attorney Anne T. Donnelly. “This defendant’s alleged home operation endangered the well-being of at least one person in need of dental care.”
Serrano was arrested and arraigned on Tuesday, facing one count of unauthorized practice of a profession, a Class E felony under New York law. She pleaded not guilty and was released to pre-trial services with electronic monitoring.
Judge Charles G. McQuair ordered her to surrender her passport and restricted her from traveling outside of New York State.
While only one victim has been identified so far, authorities suspect there may be more individuals who sought treatment from Serrano.
The Nassau County District Attorney’s Office has urged anyone who believes they may have been victimized to contact their Office of Immigrant Affairs at 516-571-7756.
The potential consequences for Serrano are severe. If convicted, she could face up to four years in prison. She is scheduled to return to court on January 8, 2025.

This case has sparked broader discussions about the dangers of unlicensed medical practices.
Patients often turn to informal practitioners for various reasons, including affordability, accessibility, and referrals from trusted sources.
However, these unregulated operations can pose serious health risks, from improper sterilization techniques to incorrect diagnoses and treatments.
The victim in this case experienced firsthand the physical and emotional toll of trusting an unlicensed practitioner. Beyond the pain and financial loss, the lack of proper medical care could have led to severe complications.
The DA’s office has emphasized the importance of seeking licensed professionals for medical and dental care, urging the public to verify credentials through official state licensing boards.
The investigation into Serrano’s activities continues, with prosecutors determined to uncover the full extent of her alleged operation.
This case serves as a stark reminder of the critical role that licensing and oversight play in protecting public health and ensuring the safety of those seeking medical treatment.
As the legal process unfolds, the focus remains on justice for the victim and the prevention of similar incidents in the future.
For now, Serrano’s case stands as a cautionary tale about the perils of unlicensed medical practices and the need for vigilance in safeguarding public health.
