Invisible Orthodontics The goal of dentists is to have orthodontic treatment done quietly without anyone noticing, and it is also a requirement for some aestheticians. An invisible orthodontic method, “lingual orthodontics”, has become increasingly sophisticated. The benefits of lingual orthodontics include aesthetics, invisible brackets, and less worry about decalcification of the tooth surface, which is less likely to occur and the incidence of tooth decay is much lower.
