Fort Worth, Texas — A Texas dentist has been arrested months after a 4-year-old girl died during what authorities say began as a routine dental procedure, with investigators alleging the child received dangerous levels of sedative medication before suffering a medical emergency.
According to arrest records, Dr. Chrishelle Hemphill, 48, was taken into custody Wednesday outside her Cuddle Kids Dental Care office in Fort Worth. She is charged with injury to a child causing serious bodily injury, a felony offense.
The allegations stem from the death of 4-year-old Aithana Arriaga, who underwent a scheduled tongue-tie procedure at the clinic on April 1.
Investigators Say Child Received Multiple Sedatives
According to the arrest warrant, investigators believe Hemphill personally administered several medications to the child before the procedure.
Authorities allege Aithana received an oral solution containing Meperidine (Demerol), along with two additional sedatives and nitrous oxide.
Police say the child later went into medical distress while still at the dental office.
Investigators allege Hemphill was the only person who administered the medications before the emergency unfolded.
Medical Emergency Led to CPR Efforts
According to investigators, the dentist began performing chest compressions after the 4-year-old became unresponsive.
A second dentist, who had reportedly been on a lunch break, joined the emergency response and continued CPR until paramedics arrived at the clinic.
Despite those efforts, Aithana later died. The investigation that followed included toxicology testing and a review of the medications administered during the appointment.
Medical Examiner Cites Meperidine Toxicity
According to the arrest warrant, the Tarrant County Medical Examiner determined that meperidine toxicity caused the child’s death.
Investigators also cited medical experts who stated that the amount of meperidine detected in the child’s system would have been considered high even for an adult.
According to court documents, doctors told investigators that the normal adult therapeutic range for meperidine is 200 to 500 nanograms per milliliter.
Testing reportedly found 793 nanograms per milliliter in Aithana’s system.
The arrest warrant further alleges investigators concluded the medication had been administered twice, resulting in what they describe as a double dose.
Those allegations are contained in court records, and the criminal case remains pending.
Family Remembers Young Girl as Investigation Continues
Unable to speak publicly, Aithana’s parents shared a tribute through a GoFundMe page, describing their daughter as someone who was “filled with life and kindness” and whose presence “always lit up a room and brought so much joy to everyone around her.”
State records show Hemphill has been licensed to practice dentistry in Texas since 2017.
Authorities have requested information from the Texas State Board of Dental Examiners regarding whether the agency has opened its own investigation or whether the dentist has any previous disciplinary history.
The allegations outlined in the arrest warrant represent the prosecution’s claims. Dr. Chrishelle Hemphill is presumed innocent unless and until proven guilty in court. The criminal investigation remains ongoing.
