Lingual orthodontics:
Lingual braces (also known as invisible braces) are attached to the inside surfaces of the teeth that face the tongue. There they are practically invisible from the outside, even up-close.
Advantages:
They are places in the inner surface of the teeth which face the tongue, hence are not visible.
They are more efficient than the clear aligner systems for complex tooth movement.
They are more efficient than traditional labial braces in bringing about certain types of tooth movement as a result of their biomechanics.
They require thinner wireswhen compared to traditional labial braces.
Disadvantages:
They are not comfortable as other bracket systems as they constantly in contact with the tongue. It would take quite some time for you to get used to the braces.
The brackets and wires will feel a little rough initially and they may affect your speech for a while.
Lingual braces are also more difficult to keep clean.
Invisible braces may not be possible for patients with short crowns.
The appointments would be more time consuming as the orthodontist has to work in braces that a place lingually.
