Authorities are investigating after a 14-month-old girl died Tuesday morning following a procedure at a northwest Austin dentist visit.

According to the Travis County Medical Examiner’s office, Daisy Lynn Torres was pronounced dead at North Austin Medical Center shortly before 12 p.m. Tuesday following a procedure at Austin Children’s Dentistry.

A YouCaring page set up by a family friend said Daisy was at the dentist for a "routine cavity filling."

Austin Children's Dentistry spokeswoman Sarah Marshall says the clinic is heartbroken by what happened

“Our thoughts and prayers are with the family. This is a tragedy, and we're just waiting to learn more information from the medical examiner's office. We want to keep the privacy of the family, legal privacy, and just respectful privacy of the family,” said Sarah Marshall, spokeswoman for Austin Children’s Dentistry.

Marshall said Austin Children's Dentistry has been in business for 40 years and these are the types of procedures that they handle all the time.

An autopsy was performed Wednesday and a cause of death is pending. A spokesperson for the medical examiner’s office told KVUE’s Michael Perchick they expect a fairly lengthy investigation into Torres’ death.

The family declined to go on camera, however Daisy's aunt did release a statement: "Daisy was a happy, healthy, baby. She was playing with the family on Easter. She went to the dentist and didn’t come home.”

The Texas Board of Dental Examiners confirmed to KVUE it has launched an investigation into Torres’ death. Marshall said Daisy was placed under anesthesia during the procedure, and all protocols were followed.
