How long does Invisalign take to work?

Invisalign treatment involves wearing a series of tightly fitted aligners to continuously move and adjust the positioning of one’s teeth. The user must wear their current aligner for 20 to 22 hours per day removing them only for brushing, flossing, eating, and drinking, and they will replace it with a new one approximately every two weeks. This will continue until the desired results are achieved, which normally takes one to two years. Time frames differ depending on degree of correction need and adherence to the schedule.
