Now, investigators are trying to determine if there are more victims.
They believe 36-year-old Saul Robles took advantage of a 15-year-old girl during her dental visits over the past six months. When the teen told her parents, they immediately notified authorities.
The abuse is said to have taken place at the Smile Care Dental in Rosemead, where Robles has worked for the past four years. He has also worked at the company's Bellflower office and authorities think there could be more victims.
If you think you might have been a victim or have information for investigators, call the Los Angeles County Sheriff's Department's Special Victim's Bureau at (877) 710-5273.
