Again, not much to tell, hence the sporadic posts. I know my teeth are moving, but I'm not seeing the difference. Then again, I haven't been taking pictures to track progress! So I took one now, at Tray 11, and providing some comparisons...
I will say that it's pretty cool to think I am halfway done with my top trays (11/22!) and more than a third done with my bottom trays (11/30!). Of course, "done" meaning "done with refinement 1." Haha!
