After sending precise treatment instructions, Invisalign® uses advanced computer technology to translate these instructions into a sequence of finely calibrated aligners — as few as 12 or as many as 48. Each aligner is worn for about two weeks and only taken out to eat, brush and floss. As you replace each aligner with the next, your teeth will begin to move gradually — week-by-week until the final alignment prescribed is attained. Then you’ll be smiling like you never have before!
