An Aligner Chewie is a small cylinder made of a soft spongy plastic-like material called Styrene Copolymer. It looks like a small roll of gauze or cotton.
You get 20 Chewies per bag (10 individual little factory-sealed bags of 2 chewies each).
Biting on an Aligner Chewie helps to seat your Invisalign aligner onto your teeth so that your treatment can progress faster.
Check with your dentist or orthodontist for specific instructions regarding how often to bite on the Chewie.
