A Houston family is considering a lawsuit against a dentist after their child suffered brain damage from multiple seizures during the visit.

Attorneys say the seizures were brought on by the use of several sedatives and a sometimes controversial restraint device.

“In essence what happened is this child was chemically and physically suffocated,” said Jim Moriarty the attorney for the family of 4-year-old Nevaeh Hall. “This child suffered massive brain damage during that time period and that didn’t have to happen.”

It wasn’t Nevaeh’s first time at Diamond Dental in Houston. Her mother, Courissa Clark, said it was her third visit and that she expected some of her daughter’s teeth to be capped or even removed because of decay.
