Exposed metal tie – Brushing your teeth or eating may cause the end of the metal ties that have been placed around your brackets to become proud. Try to use orthodontic wax to prevent ulceration. If this does not help then please call Perla Orthodontics on 01382 549675.
If you have an exposed metal tie which is sharp or digging in to your soft tissues please watch this video from the British Orthodontic Society.
