Lingual braces are placed behind the upper and/or lower teeth, creating a more aesthetically pleasing effect. Because the brackets and archwire are actually placed at the back of your teeth, they are virtually undetectable, allowing you to retain your normal appearance for the duration of your treatment.
You doctor took courses specializing in the placement of these braces. They are custom made for your maxillofacial structure. While some patients note problems with speech initially, such problems generally disappear within a few weeks and with practice.
