Basically, they are metal bracket, with the exception of that they are hidden, instead of placed on the front surface of the teeth, lingual(towards the tongue surface of the teeth) supports have various advantages. They are equally good as those placed on the front surface of the teeth, regardless of whether of metal or ceramic, however, they can’t be seen from outside of the mouth. While they can be seen only when the patient opens their mouth. Lingual supports have various disadvantages. They can be very difficult and hard to keep clean, as the patient can’t see the supports, nor is he used to cleaning the area that he presently needs to clean broadly. They likewise make it hard to talk. Like every orthodontic treatment, there is an expectation to absorb information for discourse, however, lingual supports are frequently more problematic than different sorts of brackets. Lingual braces are likewise not a good alternative for those that have severe orthodontic conditions that need broad treatment. What’s more, since they take longer treatment time and are more costly than traditional bracket, most patients don’t choose this kind of treatment.
