What are chewies for?
Chewies are small foam cylinders, used to help close any air gaps between your teeth and your Invisible Braces. Biting down on the chewie allows the Invisible Braces to fit tightly on your teeth and for the treatment to progress faster. To use your chewie correctly, position it between your teeth and bite down. Move it from one end of the mouth to the other until you have bitten on it with all your teeth.
