For three hours, a Florida mom sat in the waiting room while her 6-year-old daughter was in with the dentist. The wait turned to worry. Now it's turned to anger after she and other parents learned what was being done to their kids.

JACKSONVILLE, FL (WJXTCNN) – It's a sound no parent likes to hear: a child screaming out of fear and possibly pain from the dentist's chair.

Going to the dentist is a rite of passage, of sorts, but what's alleged to have happened at the hands of 78-year-old Dr. Howard Schneider was not.

For the past three weeks, there have been daily protests outside his practice. One parent was so angry, she attacked him outside his office.

Schneider said he's done nothing wrong.

The firestorm started after Brandi Motley wrote about the day she took to her 6-year-old daughter, Bri'el, to Schneider to have one tooth pulled.

On the day of surgery in December 2014, Motley said she was not allowed to sit with her daughter.
