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

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.

I believe your case can be treated in under 12 months using invisalign.  Braces would be your only other option which would also take about the same time.  Just make sure when your treatment is completed you wear your retainers so that they stay aligned!!!!!  Ask for a permanent retainer on the lower.  It is my retainer of choice.  A small wire is glued behind the lower teeth 6 teeth.  It is comfortable, easy to clean, and can last forever if taken care of properly.
