March 17, 2023 – Westchester County District Attorney Miriam E. Rocah and White Plains Public Safety Commissioner David E. Chong announced today that a Queens man was arraigned on multiple felony charges for allegedly practicing dentistry without a license out of a White Plains storefront set up as East Post Dental. Law enforcement officials seized several dentistry tools and equipment, local anesthetics, antibiotics, and patient files, which are being analyzed to identify other possible victims or witnesses. The DA’s Office and White Plains police urge the public to assist law enforcement with any information about the defendant or other possible victims.

DA Rocah said: “The alleged crime of illegally practicing dentistry and providing pain medication without a license is very serious. As our investigation continues, we ask anyone who may have been a patient of the defendant to contact us or the White Plains police.”

Commissioner Chong said: “Practicing any kind of medical procedure without a license is a dangerous crime. We’re happy to work with the DA’s Office in taking this alleged fraud off the streets. We ask members of the community who may have information about this defendant to please contact our White Plains detectives or the DA’s Office.”

The defendant, identified as Cesar Masso, 78, was arrested by White Plains police on March 9, 2023, and arraigned on March 16, 2023 in White Plains City Court where he was charged via felony complaint with three counts of Unauthorized Practice of a Profession for allegedly providing, without a license, dental services, including examinations, tooth extractions, anesthetics, pain management, X-rays, and cleanings to patients at a business he set up as East Post Dental located at 169 Grand Street in White Plains. The defendant accepted payments in cash or check.

White Plains police initiated an investigation with the Westchester County District Attorney’s Office after a victim reported to police that the defendant allegedly performed tooth extractions and placed a dental bridge that fell out, causing the victim discomfort and pain. The victim also received an injected numbing agent and pills for pain management. The victim paid the defendant thousands of dollars in cash for dental examinations, evaluations and the treatment between October 2019 and April 2020.

Anyone who may have been a patient of East Post Dental or may have information about the defendant can contact the DA’s Office at (914) 995-TIPS (8477) or White Plains Public Safety at (914) 422-6256. Language assistance is available.

The case is being prosecuted by Public Integrity and Law Enforcement Deputy Bureau Chief Brian P. Weinberg of the Trials and Investigations Division.

The charges against the defendant are merely an accusation, and the defendant is presumed innocent unless and until proven guilty.
