Am I Ineligible for Invisalign?

There is NO DOUBT you can use Invisalign. The only matter in question is whether or not all of your dental concerns can be resolved with Invisalign. I would suggest you consult a dentist or orthodontist who works with Invisalign (or another clear aligner system) AND conventional braces. Good luck, you will be VERY happy when the teeth are straight! 

Invisalign treatment procedures have improved significantly over the last decade and continue to advance. So the earlier dismissal of your 'eligibility" for Invisalign more than likely no longer applies. Also, you might take in to account that dentists, and some orthodontists, that are not experienced in managing Invisalign treatment  are less likely to recognize its potentials than a doctor who has extensive experience. I suggest you consult with an orthodonitist in your area whose practice includes a significant number of Invisalign patients. That way you are most likely to get the information you need to make an informed decision as to whether Invisalign is right for you.

The photo showing the crowding of your teeth makes it look like Invisalign would be able to align these teeth. The question then hinges on your bite.  It's always hard to tell from one photo what someone's bite is really like.  In some cases braces give a better result, but only a visit to your local orthodontist who does BOTH Invisalign and braces will provide the right answer for you.
