About Invisalign: Invisalign treatment is the process of wearing a series of clear, removable aligners that gradually straighten your teeth. No brackets and wires, and none of the restrictions that come with metal braces. Invisalign clear aligners are made of flexible plastic, are FDA-approved, and contain no BPA, BPS, latex, or gluten. They are thin, clear, and fit snugly over your teeth, making them virtually invisible. Unleash your best smile with Invisalign.
