Invisalign is a series of clear, removable teeth aligners that both orthodontists and dentists use as an alternative to traditional metal dental braces.

You wear each set of aligners for about 2 weeks, removing them only to eat, drink, brush, and floss. Each set of aligners, move the teeth about 0.25 millimeters per aligner.

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. You'll visit your 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.
