Invisalign® aligners are made using 3D computer imaging technology and are used by more than 70% of orthodontists in the United States and Canada. You will wear a set of aligners for approximately two weeks, removing them only to eat, drink, brush, and floss. As you replace each aligner with the next in the series, your teeth will move slowly until they have straightened to their final positions. About once every six weeks, you will come in for a visit to ensure that your smile is on the right track. Your total treatment time will be around 9 to 15 months.
