The bracket is a small metal or ceramic square that is glued to each individual tooth. If foods that are too hard or chewy are eaten then the brackets will become detached from the tooth. They will not fall off as they are still tied to the wire, however they will slide along the wire between the brackets either side. Remember if a bracket becomes detached from a tooth, the brace is not working and the tooth will move back to where it was before. If a bracket is rubbing then use some of the wax provided to cover it, until you are able to be seen.
Ligatures or Ormalasts
Ligatures are the very small elastic bands that hold the arch wire to the bracket. If one of these comes off it will need replacing as the arch wire is no longer attached to the brace.
The arch wire
Under extreme force this wire can snap, and will need replacing. If the wire is digging in, then use some of the wax provided to cover it.
Removable braces and retainers
If your appliance is broken, continue to wear it unless it is causing discomfort or no longer fits, and book a repair appointment as soon as possible. Ensure you bring all the parts of your brace and your models, so it can hopefully be repaired.
