I'm also considering invisalign. I've been wanting to do it for awhile, like you it doesn't really show up much in pictures but they still bother me. I've talked to my dentist and with the invisalign they also add the whitening to put in the trays for free. I had braces on when I was younger but after they look them off you could literally watch my teeth move back within 2 hours - an orthodontist later told me they put them on way to early, so sorry to my mom and dad who spent $4,000 on nothing.
