An Austin dentist will not face any discipline over the death of a 14-month-old girl last year who was put under anesthesia during a cavity filling.

The Austin American-Statesman reports that Michael Yanoff, a Dallas lawyer representing Dr. Michael Melanson, confirmed that the Texas State Board of Dental Examiners dismissed its investigation of his client last month.

The dental board said it its investigations are confidential and that it only comments in instances where dentists receive disciplinary action.

Daisy Lynn Torres died March 29, 2016, several hours after going to Austin Children's Dentistry to have two cavities filled.

Daisy was placed under general anesthesia during the treatment; a short time later, she went into cardiac arrest. She was rushed to a hospital, where she died.

"We are feeling numb and lost and pained," Daisy's mother, Betty Squier said in the days after her daughter's death. "You don't take your child into the dentist thinking it will be the last time you see them alive."

A 911 recording revealed that dental workers attempted CPR on the girl while they waited for emergency crews to arrive.

The Travis County medical examiner determined that Daisy died from complications from anesthesia.

"The dental board looked at this very closely, they had their own independent experts look at it," Yanoff told the Statesman. "They reviewed the evidence submitted by Dr. Melanson, and they came to a reasoned conclusion based on reviewing all of that evidence."

Daisy's family filed a lawsuit seeking $1 million in damages in February.

The lawsuit alleges that Melanson recommended an unnecessary procedure — a number of pulpotomies, or baby root canals — only because Medicaid covered the cost. The lawsuit says Daisy's dental X-rays showed no sign of decay that would necessitate that treatment.

Austin Children's Dentistry has defended the treatment plan and sued a forensic dentist, Robert G. Williams, for defamation after he concluded that the procedure was unnecessary.

Melanson is no longer employed by Austin Children's Dentistry; Yanoff would not say where he now practices.
