NEW: Texas Pediatric Dentist Arrested After 4-Year-Old Dies From Double-Dose of Powerful Opioid During Routine Tongue-Tie Procedure Dr. Chrishelle Hemphill, 48, owner of Cuddle Kids Dental Care in Fort Worth, was arrested in July 2026 and charged with injury to a child causing serious bodily injury, a second-degree felony. The charges stem from the April 1, 2026, death of 4-year-old Aithana Rodriguez Arriaga, who was brought to the clinic for a routine frenectomy. Dr. Hemphill administered an oral liquid solution of Meperidine (Demerol) along with other sedatives and nitrous oxide. The Tarrant County Medical Examiner ruled the death a result of meperidine toxicity. The autopsy found the child had been given double the intended dose, resulting in a blood concentration of 793 nanograms per milliliter — a level considered toxic even for adults. Tragic.
