How common is it for Invisalign ons to pop off?

I had around 6-8 glued on my teeth yesterday and of course my dentist used the blue light to cure it. They didn't seem loose, and oddly enough, my dentist office had me scheduled to get a "cleaning" an hour after my appointment for the Invisalign fitting and ons. By the time I was done with that, I went into the next room. I informed them that I had a previous cleaning about 2 and a half to 3 months ago at another dentist that I was going to. So, the dental hygienist said I should wait until at least about 4 1/2 months to have another. I was having problems with a couple of places on my far upper back teeth on either side where it bleeds when I floss in that particular spot, as if the gum has grown down between the teeth. She didn't see anything, but took some Arestin (what does this do technically?) and used a spinning brush...and went around on the side and outside of all of my teeth and gums with it. This spinning brush had a lot of force and I think it may have loosened 1 or two of my ons...it looks like I'm missing two, but I know for sure that I'm missing at least one on my front bottom tooth (they're using the on to pull the tooth up out of the gum more to make it a little longer). I've made an appointment for Tuesday morning, but I start wearing them this morning (9/11 around 1:30am). Will this be okay? The teeth on the other side likewise have ons on them and are being moved out of the gum to make them a little longer. Will this make both sides unproportional or will it eventually catch up and not really make a noticeable difference?
