Orthodontics is a special branch of dental medicine that focuses on achieving optimal alignment for the teeth, bite and jaw. Traditional treatment has focused on the use of braces to achieve this goal. Today, in addition to metal braces, there are a number of other treatments. Invisalign and Damon Clear braces are also available for patients who prefer other options. But one thing has not changed in the field or orthodontics, and that is the need to take x-rays before beginning a course of orthodontic treatment.
