This depends on the patient’s orthodontic requirements and the severity of the issue being corrected. On average, treatment typically lasts between 6 to 18 months. However, a more complex case could necessitate longer treatment times. The length of treatment also depends on factors including regular wear of aligners, which is typically recommended to be 20 to 22 hours per day. Wearing your aligners as advised by your New York, New York dentist contributes to the effectiveness and timely completion of the Invisalign treatment.
