The 4-year-old child died during a normal tongue tie operation performed by a Fort Worth pediatric dentist. According to the investigations, the young girl had twice the amount of strong opioids prescribed.
The owner of the Cuddle Kids Dental Care Clinic, Dr. Chrishelle Hemphill, aged 48, was taken into custody in July 2026 for causing bodily harm to a child, which is classified as a second-degree felony. The case involves the death of Aithana Rodríguez-Arriaga, aged four, in April 2026.
Aithana, a four-year-old girl, was taken to Cuddle Kids Dental Care, located at 5329 Sycamore School Rd. The reason for the procedure was a frenectomy a common procedure to release the tongue-tie, which may affect the child’s ability to talk or eat. The doctors there have reportedly given the patient meperidine (Demerol) and other sedatives, including chloral hydrate, hydroxyzine, and nitrous oxide.
It appears that the child is no longer breathing. Staff members have started CPR for her and rushed her to the Texas Health Harris Methodist Hospital Southwest Fort Worth where she is now declared dead.
The Tarrant County Medical Examiner later ruled out meperidine poisoning as the cause of death. The toxicology report revealed that the child’s blood contained around 793 ng/mL of the medication, which the investigator said was a high dose even for an adult. The normal therapeutic range for meperidine in an adult is between 200 – 500 ng/ml.
Court documents allege several critical issues during and after the procedure. Hemphill reportedly gave about double the intended dose of meperidine. Investigators say the team failed to continuously monitor the child properly and did not recognize respiratory distress quickly enough.
When the emergency unfolded, staff allegedly administered flumazenil which reverses benzodiazepines instead of naloxone (Narcan), the standard opioid reversal agent. One report noted an AED was used to check for a pulse even though the child still had one.
A police search of the clinic uncovered multiple syringes containing leftover medications in varying amounts, which authorities say raised concerns about unsafe medication practices.
A frenectomy is a quick procedure that releases the lingual frenulum. Although the procedure is generally safe, the administration of sedation to young patients necessitates additional safety measures due to the unique physiology of children and their susceptibility to respiratory depression.
Meperidine was linked to an elevated risk of respiratory depression and neurotoxic metabolite production. Consequently, many medical institutions have replaced it with alternative drugs that are considered safer in pediatric patients.
Texas Administrative Code mandates specific protocols, approvals, monitoring, and medications for use in pediatric patients.
Hemphill’s license was suspended when she was arrested for endangering the public; Hemphill was released on a $10,000 bond. Hemphill would serve up to twenty years in prison if found guilty.
These are allegations, and Hemphill has yet to be tried or convicted for any of them.
This case brings to light many issues regarding the risks to patients, the dangers of sedation, and the importance of proper monitoring and medication. This may lead to stricter guidelines and monitoring in outpatient surgical facilities to ensure the safety of their young patients and the trust of their families. Patients and their families should be able to have confidence in the safety of procedures, especially when they are not there.
