Crooked or misaligned teeth can be painful and cause digestive issues. After exams and x-rays, an orthodontist may recommend braces to correct the issue. Braces use various removable and fixed dental appliances like brackets, bands, arch wires, ties, and elastic bands to apply pressure over time and slowly guide teeth into their proper positions to restore a beautiful smile. Different components of braces perform different functions to move teeth and change bone shape as needed.
