Just did this before and after comparison and am happy with the results so far! One of the things I'm happy about is that my upper lip doesn't get as thin when I smile. I think that has to do with the fact that the teeth are no longer angled so inward, which previously caused my gums to push out a bit right where my upper lip would lay. That "ledge" pushing outward would cause the upper lip to be forced above it, causing the upper lip to be thinner when I smiled. I think the profile looks significantly better as well.
I'm also looking forward to see the gumminess reduce even more when the gum swelling goes down after the brace are off.
I think I'll likely be out of braces by the end of March, hopefully! That would put me at a total treatment time of 24 months. It seems like such a long time for these changes, but most of the changes were actually in fixing my overbite. Moving those front teeth back in line has taken so long.
