Invisalign provides an alternative to traditional metal braces. This treatment uses plastic aligners to straighten your teeth. The aligners are clear. Once placed in your mouth, they become practically invisible, and no one will be able to tell that you are wearing them. In addition to being clear, Invisalign aligners are removable. They should, however, only be removed to eat and to brush your teeth. This allows you to enjoy all of your favorite foods as well as brush and floss your teeth as normal.
