Orthodontics is a branch of dentistry that works on preventing, diagnosing and straightening of badly set teeth and surrounding structures.Although it is commonly believed that orthodontic therapy is only used for aesthetic reasons, it is initially used for establishing a good function by correcting the functional irregularities of teeth and the relationship between the upper and lower jaw, thus leading to improved aesthetics.< But of course, good function brings good aesthetics. Irregularities in the positioning of teeth could cause numerous problems such as difficulty in maintaining oral hygiene which leads to appearance of cavities and plaque or worse, serious problems in the jaw joint accompanied by headaches. <
