Orthodontics, division of dentistry dealing with the prevention and correction of irregularities of the teeth—generally entailing the straightening of crooked teeth or the correcting of a poor bite, gaps between teeth or malocclusion which may be caused by imperfect development, loss of teeth, or abnormal growth of jaws. Orthodontists use either the Dental braces which are metallic devices used to align and straighten teeth and help position them with regard to a person's bite, while also aiming to improve dental health. Or the Clear aligners treatment, an orthodontic device that is transparent, made of transparent plastic used to adjust teeth.
