Orthodontics, or braces, is a special discipline of dentistry concerned with aligning the teeth and jaws to improve your smile and oral health. Dentists usually recommend braces to improve the patient’s physical “orofacial” appearance. Through orthodontic treatment, problems like crooked or crowded teeth, uneven spacing due to missing teeth, overbites or underbites, incorrect jaw position, and disorders of the jaw joints are corrected.
