Today, there are metal braces that can be placed on the “tongue side” or lingual of every tooth. Known as lingual braces, these appliances are completely hidden from the outside world. While these braces work in the same way as the metal or ceramic braces affixed to the front of your teeth, they can only be spotted on close inspection during such times as when your mouth is wide open. Far less obvious than most other types of braces, lingual braces, due to where they are located, can be a bit more uncomfortable and more difficult to keep clean. It is also more of a challenge to get used to speaking with this type of orthodontic appliance.
