Last night I changed trays. As I stated in a forum comment, the bottom was a little more difficult to put on than Tray 6, but not any more difficult than, say, Tray 2 (when I was still a newbie at this whole thing!).
I skipped lunch today just to prolong the amount of time for my teeth to get acquainted with the trays, before eating dinner after I got home. For the first time, it REALLY hurt getting them out, especially the top tray! Usually there's some pain, but it seemed moreso than usual. I was able to eat okay, and putting the trays back on was no problem/no pain. But it seemed strange how much it hurt to get the top tray off. The bottom hurt too, but not as bad. I wonder if it's how the teeth are moving at this stage? I don't know. I just hope it doesn't hurt that much tomorrow when I take them out to eat!
This time, for my photos, I did something a little different (that other people have done). Since this is my last tray before my next appointment, I will be parting with Trays 1, 2, 4, 5, 6, and 7 to give to the orthodontist office for safe-keeping (they already have Tray 3). So no more comparisons with Tray 1 (man, I'd LOVE to go back and see the difference once I get in the double-digits).
Anyway, so before I bid those trays adieu, I decided to get pictures to compare Trays 1 and 7. I took pictures last week of the actual trays, and tonight I took pictures of my bare teeth to compare to pictures from a few days into Tray 1.
Tray 1 is on the top or left, and Tray 7 is on the bottom or right.
