The invisible way to straighten your teeth without braces. For more information on Invisalign, please visit www.invisalign.com. 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 Dr. Lewis’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 Dr. Lewis has prescribed. You’ll visit Dr. Lewis 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.
