See an Invisalign doctor and have them take impressions and X-rays and Photos, and they can submit it to Invisalign for a ClinChek, and that will give you a definitive answer if it can be done or not.

Teeth Too Crowded for Invisalign?
It is hard to tell if you are a candidate for Invisalign without evaluating your entire bite and the positioning of your teeth. The proper evaluation would require your dentist or orthodontist to take impressions, pictures and X-rays. Then they would send all this data to Invisalign and, based on the final bite and look you would like to achieve, Invisalign would send back a "Clincheck" to your dentist. You and your dentist will sit down and evaluate this together and see if Invisalign is able to accomplish what you want. Good luck!
