I am on Invisilgn express and am just not on the first set of ten. The orthodontist said it was just a lot of very little movements that have been made. My teeth are not completely horrible but I I really want them to be as perfect as possible.The pain i experienced the first few days was horrible. But now amazingly enough theu practically pop in and out. I am dreading the next set cuz I'm sure they will hurt juast as bad at first. So I am goin to try to post pictures on here and i am really just wanting the opinions of anyone who has already finished or is almost finished with express invisilign. Do you think i my teeth will be much straighter with only ten sets?? I find it kind of hard to believe but you tell me!
