I'm on my second set of invisalign trays and I have about another week until i'm supposed to switch to my third set. I lost my top retainer and was wondering if it'd be alright to hold out until I go to the dentist in a week to get my new set. I'm away at school so I have to wait until I can go home in a week to get my attachments glued on and my third retainers. Would it be better to not wear anything until next week? or should I put in my last tray?
