I had my 6 invisalign attachments (or buttons) removed a few days ago. 5 left behind a rough texture. 1 was not fully removed so I will need to ask about it at my next checkup. How long does it take for the rough texture to go away? I am assuming a couple cleanings and polishings by my dental hygienist will take care of it. Or maybe just several months of brushing. Also, for whitening, can I start now, or should I wait until the texture is smooth again? Thanks!
