Should I Expect a Treatment of Invisalign to Last for over 12 Months?

Thanks for sending your pictures.  They are quite helpful.  Assuming there not other complications, like TMJ Dysfunction, your case is not severe and looks like treatment will be well under a year.   Invisalign can be very effective in treating mild to moderate crowding and these days can treat more complex problems that were not treatable just a few years back.  The bottom line is that you should go ahead with an evaluation from a competent, seasoned Invisalign provider.  I know that visit will allay any concerns you may have.

Great question! Looking at your pictures it looks like Invisalign would be an ideal treatment for your lower anterior crowding. Treatment time for Invisalign averages a year and your case looks to be pretty average.  

Good luck!

Based on what you’re showing us, your Invisalign treatment would indeed be likely to take less than a year to complete although it may be closer to the full year or just over. Of course, pictures don’t tell a full story, so an orthodontist would have the best estimate.
