End bracket came off braces?!?

I just got braces two days ago. I was brushing my teeth a few minutes ago with a little special brush to go between my braces like this: a href="http://www.google.com/imgres?imgurl=http://sale.dentist.net/ets/products/1374/product/butler-gum-go-betweens-cleaners-872p.jpg%3F1273699098&imgrefurl=http://sale.dentist.net/products/butler-gum-go-betweens-cleaners-872p&usg=__k_DRvqtKROGwgcEUMzMFJRa3Jhg=&h=300&w=300&sz=7&hl=en&start=0&zoom=1&tbnid=amg6QRCeSXkIzM:&tbnh=130&tbnw=133&ei=KcSnTZ2SIOyI0QG7-7X5CA&prev=/images%3Fq%3Dgo%2Bbetweens%2Bgum%26um%3D1%26hl%3Den%26sa%3DN%26biw%3D1229%26bih%3D518%26tbm%3Disch&um=1&itbs=1&iact=hc&vpx=292&vpy=178&dur=2566&hovh=225&hovw=225&tx=144&ty=106&oei=KcSnTZ2SIOyI0QG7-7X5CA&page=1&ndsp=16&ved=1t:429,r:2,s:0." rel="nofollow"http://www.google.com/imgres?imgurl=http…/a and anyways, the brush poked my braces or something and it just fell off. The wire is poking my cheek a lot since it was the bracket on the very end in the back, and the wire is sticking out. I put a bunch of wax on it, but the wax usually falls off when I eat or brush my teeth. The problem is, my orthodontist isn't open Friday, Saturday, or Sunday. So I won't even be able to call until Monday, and who knows when the next open appointment is or whatever. I'm really scared because I'm REALLY new to braces because I JUST got them on Tuesday. Will they be mad at me? ahh I'm scared!! I told my mom, she said she'd call monday. How long do you think it'll take for me to be able to get them fixed? what should I do until then? should I just keep putting wax on them? oh and I have another question, do they give you more wax when you go to get your braces tightened?
