It takes lots of factors coming together to make a nice smile, not just getting the teeth in line or "straight. I am just going to list some things you could look into, sorry there are so many, some people are just lucky that way. -Gums, yours are to thick and are actually covering up part of the tooth that should show. Google "altered passive eruption" and how to correct it. -Shape of teeth, yours are less than ideal. bonding or veneers would help -proportion: Length to width ratio of each individual tooth, as well as the size relationship to each other. Fixing the shape would also fix this. -Lateral incisor roots still to far back, so emergence profile is off. (this is impossible to correct with invisalign and is often undertreated in braces) -Incisors are to upright in the facial-lingual plane, also hard to fix with invisalign. -upper left lateral tipped, not enough space created to get it in place. Good news is all of this is fixable, it just takes a good orthodontist willing to do the work and address each of these issues. And it will take braces, but probably a year or less. Hope this helps, good luck.
