Dr. Duffy over treated my kids. I have since had two second opinions and my children no longer have cavities when she was diagnosing one or two at each visit. I am so glad I got a second and third opinion. She didn't start over treating until we had been patients for 5 years and no longer carried insurance. She raked me over the coals. Also, I feel bad that my kids may not have needed the fillings I agreed to at the two check-ups prior to seeking a second opinion. It has been two years and all three of my girls have been cavity free since leaving and seeing two separate dentists. I really wanted to be careful that the first opinion after Duffy wasn't missing anything. I feel awful this happened because I liked her office. Just please, get a second opinion.
