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

The most optimal tooth movement for Invisalign is 0.1mm per aligner. Therefore, find the most crowded teeth in your mouth. Measure how far off the alignment is. Multiply by ten (the amount of aligners needed). Then divide by 2 (2 aligners per month). That will tell you how many months of treatment is needed. Your case could go over 12 months.

If you finish faster, all the better. There could be unforeseen problems that might prolong the treatment.

Good luck!

Invisalign works great for lower crowding and the length of time required is different for every case. Most cases run about 8-12 months.
