Invisalign isn't strong enough to correct all problems, so that might be a big deciding factor! I was so against the idea of traditional braces that I shopped around until I found someone willing to try Invisalign on me, and it ended up being a huge waste of time and money

Also agree with one of the previous comments that you need to be really disciplined about using it for the minimum number of hours each day. You'll end up brushing your teeth 3 or 4 times a day (after every meal) and you can't drink much other than water while the aligners are on.
