The clear alternative to braces. Invisalign is a virtually invisible solution to getting the smile you have always wanted. Using a series of clear, removable aligners, Invisalign gradually moves your teeth and almost no one will know you are wearing them unless you tell. You visit your doctor every month or two to check your progression and get new aligners. Average treatment time is about a year, and because the aligners are removable, you can eat your favorite foods and brush and floss normally to keep your teeth and gums healthy.
