Fort Worth Dentist Arrested After 4-Year-Old Dies Following Dental Sedation

What Happened at the Fort Worth Dental Office?

Fort Worth police have arrested a pediatric dentist more than three months after a 4-year-old girl died following a dental procedure, according to reporting by NBC 5 Dallas-Fort Worth and CBS News Texas.

According to police, 4-year-old Aithana Rodriguez Arriaga was brought to Cuddle Kids Dental Care on Sycamore School Road in Fort Worth on the morning of April 1, 2026 for a frenectomy — a routine procedure to treat a tongue-tie. The girl became unresponsive after the procedure and was taken to a local hospital, where she was pronounced dead. The Tarrant County Medical Examiner ruled that she died of meperidine toxicity — an overdose of the opioid pain medication also known as Demerol.

In mid-July, police arrested Dr. Chrishelle Hemphill, 48, on a warrant charging her with injury to a child causing serious bodily injury, a second-degree felony, according to the Fort Worth Police Department. The charge is an accusation: Dr. Hemphill has not been convicted, and the criminal case will be decided by the courts.

What the Arrest Warrant Alleges

News outlets reviewing the arrest warrant affidavit, including WFAA and FOX 4, report that it alleges:

• The 44-pound child was given meperidine before the procedure, along with additional sedating medications and nitrous oxide — a combination that can suppress breathing.
• The medical examiner determined the meperidine level in her system — 793 nanograms per milliliter — was above what doctors described as a normal adult range of 200 to 500, and told investigators the medication had been given twice.
• Neither the dentist nor her staff could immediately say how much medication had been given, according to investigators.
• Medical experts identified failures in how the child was monitored and in the emergency response after she stopped breathing, including the administration of the wrong reversal medication.
• Staff statements that the child had undisclosed breathing problems were disputed by the girl’s own doctors, who told detectives she was healthy — and one of her doctors questioned whether she had a tongue-tie condition at all.

The Dental Board Suspended Her License

According to CBS News Texas, the Texas State Board of Dental Examiners held an emergency meeting the same week as the arrest and suspended Dr. Hemphill’s license after determining she “would constitute a clear, imminent, or continuing threat to a person’s physical health or well-being.” She had been licensed as a dentist in Texas since 2017. The board is the state agency that licenses dentists and issues the separate sedation and anesthesia permits required to sedate patients in Texas dental offices.

Who Can Be Affected?

A case like this raises questions for more families than one:

• The parents and family of a child who dies after a procedure — the family members Texas law recognizes in a wrongful death case
• Parents of any Texas child who was injured, oversedated, or deprived of oxygen during a dental or medical procedure — even where the harm was less visible than in this case
• Families now wondering whether a procedure their child is scheduled for requires sedation at all, and what questions they may ask the provider
• Anyone facing medical bills, funeral costs, or long-term care needs because of an injury during treatment

What Kind of Claim Might Apply?

Attorneys who handle Texas medical injury cases generally describe several paths that can apply once the facts are established:

• A medical malpractice claim — in Texas, claims against dentists and other health care providers for treatment that departs from accepted standards of care are governed by Chapter 74 of the Texas Civil Practice & Remedies Code, which sets special procedures, including a required expert report early in the case.
• A wrongful death and survival claim — under Chapter 71 of the Texas Civil Practice & Remedies Code, the surviving parents of a child killed by another’s wrongful act can generally seek compensation for their losses, and the child’s estate can bring a survival claim.
• The civil case is separate from the criminal case — a criminal prosecution is brought by the State and decides guilt; a civil claim is brought by the family and decides compensation. They proceed in different courts under different standards of proof, and a family’s civil rights do not depend on waiting for the criminal case to end.
• Deadlines — for most Texas health care liability claims, Section 74.251 sets a two-year statute of limitations, with limited exceptions.

A lawyer can obtain the dental chart, anesthesia and medication records, and the medical examiner’s findings, have them reviewed by qualified medical experts, and identify every claim and insurance source that may apply.

Why Acting Quickly Can Matter

Texas medical malpractice cases move on an unusual clock: before most suits can proceed, an expert report must be prepared and served under Chapter 74’s deadlines, and building that report takes records, expert review, and time. Meanwhile the criminal case and the dental board proceedings run on their own tracks — and the civil limitations period runs regardless of either one. Many families choose to have a lawyer preserving records and monitoring those proceedings on their behalf from the start, so no deadline arrives before they are ready.
