Braces, also called fixed orthodontic appliances, generally come in three types:
Brackets, metal or plastic, clear or tooth-colored, that are bonded to teeth
Lingual-type brackets that attach to the back of teeth, hidden from view
Metal bands that wrap around and cover most of the teeth
All three types use wires to move the teeth to the desired position
Another type of orthodontic device that can be used is aligner therapy. Aligners are removable, custom-formed plastic guides that fit over the teeth. They are used in a series to move teeth to their desired positions.
