Wire moves and gets stuck on top behind the bracket

So I was eating bbq chips, then I guess the chip got stuck in between the braces. Then I went to the bathroom because I hear a pop. Half the elastic ligurature had come off, so I pushed back. I thought everything was fine, but there was weird pressure on my teeth. I noticed that the wire was not straight on the tooth. The elastic was around the bracket(like normal) but the wire wasn\'t in the middle.it was on top behind the bracket on the tooth.so basically, the elastic isnt holding anything. The only time I can go to the dentist is in two weeks. I don\'t know what to do and I don\'t know if this will cause major damage to my teeth. I can tell that the tooth is starting to push down and my gum is popping out slowly. When I close my jaws, it hurts. the last time I have gone to the orthodontist is last Saturday, and this is my second appointment I have braces and brackets on and a metal molder on my four teeth second to last.
