Dental braces. View of a 16 year- old girl with fixed dental braces. Fixed braces consist of metal brackets cemented to each tooth, with an adjustable wire threaded through each bracket. Braces (or orthodontic devices) are worn to correct poor alignment or overcrowding of teeth. Fixed braces are used when many teeth need repositioning as they give more precise control over teeth movement than removable braces.
