Traditional braces treat an abnormal bite & mal-positioning of teeth. These are available in metal or ceramic.
Lingual braces are similar to normal braces but they are placed behind the teeth; they are also available in metal & ceramic.The major advantage of lingual braces is that these are not visible because they are on the inner side of the teeth.
Invisalign is an alternative to traditional braces. Invisalign treatment consists of series of clear, removable aligners that are changed every few weeks. These custom made aligners are nearly invisible. The aligner corrects the malposition of the teeth.
