Dental braces (also known as orthodontic braces, or simply braces) are devices used in orthodontics that align and straighten teeth and help to position them with regard to a person's bite, while also working to improve dental health. They are often used to correct underbites, as well as malocclusions, overbites, cross bites, open bites, deep bites, crooked teeth, and various other flaws of the teeth and jaw. Braces can be either cosmetic or structural. Dental braces or orthodontic braces are often used in conjunction with other orthodontic appliances to help widen the palate or jaws and to otherwise assist in shaping the teeth and jaws. This involves correcting irregularly placed teeth with fixed and removable braces/removable trainers. Invisible (ceramic) braces are also available to the beauty conscious.
