This type of orthodontic bracket is placed in the inner wall of the teeth towards the oral cavity and tongue. The most important advantage of using this type of braces is its beauty. Because the lingual bracket is attached to the back of the tooth and is not visible when talking or laughing.
Lingual orthodontic brackets are more expensive than traditional metal brackets. They are also more difficult to fix on the tooth than other types of braces and require periodic adjustments for a longer period of time.
It should be noted that Lingual braces are not considered very effective in cases of severely irregular teeth.
