Following your orthodontic care will always save you from any oral health injury. In case of an orthodontic emergency for braces having a broken wire, on urgent basis, you must use a clipper to cut the wire or use an orthodontic wax provided by the orthodontist. However, you should seek an appointment in future for a professional care. If the elastic bands are broken you must carry extra elastic bands with you every time in your orthodontic care kit.
