The bracket on the ring of my back tooth fell off so the wire fell of with it. What should I do? (Photos)

It doesn't cause pain or anything but sometimes the bracket that hangs off bothers me. And I moved to a new country so I won't be going to a new dentist in a month, but I don't know wether I should book an immediate appointment just for this problem or wether I should just wait until I go to my new dentist
