Invisalign straightens your teeth using a custom-made series of plastic aligners created for you and only you. These aligner trays are made of smooth, comfortable, virtually invisible plastic that you wear over your teeth. They gradually and gently shift your teeth into place. There are no metal brackets to attach and no wires to tighten. You pop in a new set of aligners approximately every one to two weeks until your treatment is complete. You’ll achieve a great smile with little interference in your daily life. Invisalign is the invisible way to straighten your teeth.
