what patients rave about
I am so impressed with Mastroianni Orthodontics. I've been concerned about my 8 1/2 year-old son's baby teeth falling out and permanent teeth coming in crooked. I called Mastroianni Orthodontics and asked if my son was too young to be screened for braces, as I wanted to catch any problems early. The staff members answering the phone were friendly, knowledgeable, and explained to me that most kids should be screened by 9 or 10. So, I was on target. They also explained to me - to my shock and surprise! - that my initial visit, exam and x-ray for the screening was free of charge.
