Another thing I was worried about was the hygenist being careful around my attachments. So the first thing I said, before sitting down, was explaining I had Invisalign and that I had attachments. Then I took my trays out and sat down, and it all seemed to go okay. I was a little paranoid at one point that she was pushing the brush too much towards my teeth, and that my teeth would shift, but when I was in the car before heading to work, I put my trays back in and they went on fine. (Yes, I get unnecessarily paranoid about things sometimes).
Anyway, glad everything went well. Had x-rays done and didn't even need to see the actual dentist. I go back in August! And I'm now halfway done with Tray 6... next week is Tray 7, my last tray until I go back to the orthodontist.
