A loose bracket is one that is no longer bonded to your tooth. It is usually still attached to the wire and can spin or move around. It this occurs, place some wax over the top of it to smooth it over. Use our contact email form to let us know of the situation, and we can assess if it is an appropriate repair under the current government guidelines.
In the meantime, do your best to keep yourself comfortable. Remember to remove the wax for brushing so you can continue to keep the area very clean ready for the time when we can see you for a rebond.
