Power chain ripped about a week ago and now my teeth hurt. (Photo)

My teeth hurt because power chain ripped apart. It ripped about a week ago. My appointment will be on Thur, Feb 18th but I can already feel that one of my tooth, the one that there is no power chain on, starts moving back. Will it b ok to wait until Thur? I have been having braces only a year and 4 months. Is it a big deal Or it has to be taken care of asap? Thank you so much.
