Our accelerated Invisalign treatment where your trays are usually changed out weekly can typically take anywhere between 3-9 months. This depends on the level of correction needed and varies per patient. More complex cases will take longer to complete, and if you fail to wear your aligners 22 hours per day treatment time will be longer and may jeopardize the outcome. As part of our evaluation, we develop a customized treatment plan for each patient, so you understand what is required and how long the clear aligner trays must be worn each day.
