When I put in my trays last night, I was worried that one tooth would have root pain like at the beginning of Tray 12. But surprisingly, I woke up this morning with only minor soreness, and that was on other teeth. That tooth must have just moved a lot last tray, and this tray other ones are moving.
Also, I was glad that the bottom trays snapped on without much effort. Usually it takes a little effort to get the bottom tray on, and there were a tray or two previously that went on easily, but it's been a while. That was nice for a change!
I think the teeth are looking great so far. Not perfect, by any means, but straighter than when I started!
