Fixed retainer re-glued now teeth have moved and there are spaces! Will I have to redo my treatment?

I finished my invisalign treatment & had fixed retainers placed on my lower teeth, two months ago. Just the other day, the glue on the wire came off one tooth! the following day, I had an appointment at my orthodontics office and a hygienist replaced the glue...now after a couple of days, I am noticing spaces between these teeth that weren't there before! I am so upset about this...is it because the wire was tweaked when it was re-glued? Will I have to do treatment again to fix these spaces?
