Invisalign aligners are highly desirable compared to other treatments, primarily due to their appearance and comfort. Lingual braces are when brackets and wires are glued to the inside facing of the tooth, allowing patients to undergo orthodontic treatment without covering the front of the teeth with metal appliances. However, they can still be uncomfortable for patients, and any loose wires or brackets can become problematic. Lingual braces can also be incredibly difficult to work around with brushing and flossing, making them less desirable than Invisalign aligner trays, which can be easily removed and replaced.
