Linguistic orthodontics is a highly successful and visually pleasing treatment method for addressing malocclusions. It possesses a multitude of advantages in addition to potential disadvantages, including speech impairments, mastication restrictions, and oral agitation. Lingual braces can cause gingival hyperplasia and impact the health of the gums and periodontal tissues. This study conducted a systematic review following the PRISMA standards, specifically examining lingual orthodontic treatments that were the subject of randomized controlled trials. The study found that lingual brackets are more advantageous than buccal brackets for flat surfaces. Both types of brackets have been found to be associated with an elevation in plaque retention, gingival irritation, and S. mutans count. Because of an increased demand for adult orthodontic care, there are designed discrete treatment options such as lingual bracket systems. The demand is largely driven by appearance and cosmetics. Apparently, lingual brackets proved to be more efficacious for the prevention of caries on flat surfaces. Additional research is necessary to gain a comprehensive understanding of lingual orthodontic efficacy and safety compared to its counterpart
