Yahooo....after nearly 3 years including a lot of follow ups I'm finally done with my Invisalign treatment and my teeth have never looked better!!! I had braces as a teen and, ahem, a few years later they had drifted quite a bit, especially on the bottom. Not severely but enough to where it bothered me. But at my age there was no way I was going to do metal braces again. I'm finally done!! No more follow ups unless I have a problem with the wire along my inner bottom teeth (to prevent future drifting) or the retainers I wear at night. If anyone would like more info about it please feel free to PM me!!!
