How Long Does
Invisalign Take?
Invisalign treatment typically takes 5-18 months, depending on the complexity of your case. Mild crowding can be resolved in as little as 5-6 months.
Treatment Times by Complexity
Mild cases (minor crowding, small gaps): 5-8 months. Moderate cases: 8-14 months. Complex cases: 14-18 months. Your Invisalign consultation includes a 3D digital scan showing the predicted timeline and result.
What Affects Speed
Wearing aligners 20-22 hours daily is critical. Compliance directly affects treatment time. Skipping aligners or wearing them less than recommended extends treatment significantly.
