If you have a loose bracket that is causing pain or irritation, you can try a few different solutions at home before going to your orthodontist's office. If you have dental wax, you can try applying some on the top of the bracket so it won't irritate the surrounding tissue. If that's not possible, you can grab a pair of sterile tweezers and move the bracket back into place. Hopefully, it can stay stuck in there because of the metal wires' pressure. Lastly, if nothing else is working, you can try to remove it with a pair of tweezers.
