Will my teeth move after seven months of wearing an overnight retainer?

Unfortunately my dog chewed up my bottom set of retainers so I can no longer wear them but I am worried about going to the orthodontist to get a new pair which would be the second time. So I am therefor wondering whether my teeth will still love if I don't wear my bottom set because I've been wearing them for 7 months and have started to ween myself off.
