What happens if a bracket breaks or a wire rubs?

Yes. Teeth can move after treatment, so retainers are normally needed long term. Your clinician should explain whether fixed, removable or combined retainers are appropriate. Fixed retainers are thin wires bonded behind the front teeth and stay in place, while removable retainers are clear plastic trays or wire-and-acrylic plates worn mostly at night. Both need cleaning, and a fixed retainer that comes loose or a removable one that no longer fits should be looked at promptly.

Contact your provider quickly because teeth can move when retainers are not worn. A replacement may need a scan, impression or repair, depending on the retainer type. Do not try to bond a broken fixed retainer back on yourself, and avoid wearing a damaged removable one if it has sharp edges. If it will be a few days before you can be seen, ask whether the practice can offer interim advice or a quick-turnaround replacement.
