I took some pictures on my fourth day of Invisalign, without the trays in. I wish I had taken a picture before it all started, to show my progress, but it's not like they moved that much (and the attachments aren't THAT noticeable, right? :) ) Well I also took a few pictures tonight, with the trays in. I may or may not take pictures with each tray, but I think every so often will be good. It'll be interesting to see the differences once the changes become noticeable!
