What Are Invisalign Chewies & How to Use Them

Invisalign Chewies

Invisalign chewies are a useful device that you chew on to close any air bubbles between your Invisalign aligners and your teeth. They improve the fit of your aligners and ensure they feel comfortable and work properly. Invisalign chewies are necessary only if the aligners aren’t fitting correctly, usually when you first switch to a new set. Most of the time, your aligners should fit perfectly, due to the superior fit of Invisalign SmartTrack™ material.


Chewies are made of a soft plastic; they’re about the size and shape of a pencil grip or a cotton roll. They’re specifically created and designed for clear aligner treatment, to improve fit and comfort.


When you first put on a new set of Invisalign aligners, they may not fit perfectly at first. Chewies help work the aligners into a better fit. Simply bite down on a Chewie and chew for 5-10 minutes a day, shifting it around to different parts of your mouth, especially anywhere you feel or see air bubbles, which means the aligners aren’t snug against your teeth. You can chew on them as often as you need to, but they are usually used when adjusting to a new set of aligners.


The best time to use Invisalign Chewies is at night, before bedtime, to keep your aligners snug in your mouth while you sleep. Wash them with warm soap and water and reuse until they lose their shape and elasticity. Your dentist can provide you with a replacement package, or you can easily order more Chewies online.
