Not all orthodontic braces are planted on the front of your teeth. There are special braces that do their work behind the teeth called lingual braces. And because they are bonded behind the teeth, you’ll never know if a person uses one or not. The braces are customized to bond at the back of the teeth so they remain invisible when smiling.The lingual brackets are to be held closer together since the inner arch around the backside of the teeth has a smaller dimension than the arch on the outside. This makes both the installation and the subsequent adjustment visits more difficult. The lingual braces can also irritate the tongue initially than with regular braces. In addition, because the process is more involved and tedious, lingual braces cost more.
