Invisible aligners (ex. Invisalign) straighten your teeth with a series of clear, virtually invisible custom-molded aligners. By using a series of clear, removable aligners, Invisalign straightens your teeth with results you'll notice sooner than you think. The course of treatment involves changing aligners approximately every one-to-two weeks, moving your teeth into straighter position step-by-step, until you have a more beautiful, balanced smile. And unlike braces, these clear aligners can be removed while you eat and brush your teeth as usual.
