Invisalign™ uses a series of clear removable aligners to straighten your teeth without metal wires or brackets. The aligners are made through a combination of the dentist’s expertise and 3-D computer imaging technology. You wear each set of aligners for about 2 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 - little by little, week by week - until they have straightened to the final position the dentist has prescribed. You'll visit the dentist about once every 6 weeks to ensure that your treatment is progressing as planned. Total treatment time averages 9 - 15 months and the average number of aligners worn during treatment is between 18 and 30, but both will vary from case to case.
