The Invisalign system is the virtually invisible way to straighten your teeth and achieve the dazzling smile you've always dreamed of. Through a series of clear aligners are custom-made for your teeth – and your teeth only – to move them little by little. Each aligner is worn for about two weeks before being replaced by the next in the series, until the final position of your teeth is achieved. Your Invisalign treatment time will be determined by your doctor, based on your specific needs.
