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 your doctor has prescribed.
You'll visit the dental practice about once every 6 weeks to ensure that your Invisalign orthodontic 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.
