I, of course, compared the new with the old and found the Top Elevens are SMALLER than #10's. As in, when I over-laid them on top of each other, the top front teeth were brought inward making the aligner smaller. Does that make sense? Other than that, no change. Not a whole lot of pain, some pressure, the usual. Somehow I always end up getting head-butted right in the mouth on the first day of every change. Ouchie! ... but never any other day.
I can't wait until I'm done and I have perfect teethies! Not too much longer now but I'm getting impatient! I'll just keep reminding myself - I would have to wait TWO YEARS if I was in regular metal braces. 2 Years!!
