"Aligner Chewies” are small, spongy cushions that help to close any air gaps between aligners and your teeth and helps to seat aligners in its correct position. New aligners may not fit tightly at first, and using chewies to provide extra pressure can help straighten your teeth faster. Aligners work by moving your teeth into new positions using orthodontic force. But they only work if they fit correctly.
