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 orthodontist or dentist has prescribed.

You'll visit your orthodontist or 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.
