Invisalign Chewies: What They Are and Why They Matter

If you've just started your Invisalign journey, you may have found a small, soft cylindrical accessory included with your aligners, called a chewie. You might be thinking: what is this little thing for? Do I really need Invisalign chewies?

Chewies help your aligners fit more snugly against your teeth, ensuring they are properly seated. While they may seem insignificant, they play an important role in keeping your treatment on track. In this blog, you’ll learn what Invisalign chewies are and how they work with your aligners. 

What Are Invisalign Chewies?

Invisalign chewies are soft cylinders that are made of a flexible, medical-grade material called styrene copolymer. They are safe for use in the mouth and are roughly the size of a small cotton roll, or about 1-1.5 inches long. They are meant to help your Invisalign aligners to fit well against your teeth.

Whenever you switch to a new set of Invisalign aligners, they may not sit flush against every tooth straight away. There are often small spaces between the aligner and your teeth. Biting down on a chewie helps reduce these gaps, allowing the aligner to apply the necessary pressure to guide tooth movement according to your treatment plan. 

What Are The Different Types of Invisalign Chewies?

There are various types of chewies to suit different needs and preferences: 

• Cylinder-shaped ones are smooth and uniformly shaped. They help to the aligners seat evenly on your teeth.
• There are scented or flavoured chewies. They come in different colors and flavours like mint, grape and bubblegum.
• For Invisalign users who also wear elastics, there are chewies with hollow channels for a comfortable fit around the accessories.

How Do Invisalign Chewies Work?

Each time you put in a new set of aligners, they are designed to represent a slight advancement from your previous position. This means they will feel a little tighter and may not sit in fully at first. When you bite down on a chewie and work it around different areas of your mouth, the pressure helps close those small gaps between the aligner and your teeth. This ensures the aligner is fully seated and able to do its job effectively. 

Chewies therefore help to reduce those gaps so that your aligner makes proper contact with each tooth. This will help support the treatment for a straighter smile.

How to Use Invisalign Chewies?

This involves some simple steps:

1. Put your aligners in as usual
2. Place the chewie between your upper and lower teeth on one side
3. Bite down gently and hold for a few seconds
4. Move the chewie along to the next section of your mouth and bite down on each part for a few seconds.
5. Work your way around your entire mouth. Do this especially where you see gaps between your teeth and the aligner, so that you don't miss any spot.

Most dentists recommend using your chewie for around 5 to 10 minutes each time you reinsert your aligners, and particularly when you first switch to a new set of trays. Your dentist will advise you on how frequently to use them based on your specific treatment plan. 

What Are The Benefits of Invisalign Chewies?

The major benefits of chewies include:

• Snug aligner fit: An Invisalign chewie helps with aligner seating by reducing the small gaps between the teeth and clear aligner.

• Effective treatment: Properly seated aligners work as designed, helping to keep treatment on schedule.

• Increased comfort: An aligner that fits well is less likely to dig into your gums or feel uneven.

• Affordable: It’s a low-cost dental accessory that supports your Invisalign treatment for the intended outcome.

Who Needs Invisalign Chewies?

If you have just started with your new custom aligners, it is good to use chewies for a comfortable fit. They are particularly helpful if: 

• You have just switched to a new set of aligners and notice small gaps

• You have attachments (small tooth-coloured bumps bonded to certain teeth to help with more complex movements). Chewies help the aligner seat properly around these. Click here to learn about attachments.

• You tend to have areas where the aligner doesn't feel fully secure

How to Care For Your Invisalign Chewies

Chewies are reusable, so proper care will extend their lifespan. You can follow the below steps to maintain them:

• You should rinse your chewie after you use it. Run your chewie under water to get rid of the saliva that is on it.
• Wash with a mild, unscented soap when needed, then rinse thoroughly.
• Air dry in a clean place before storing.
• Avoid hot water, bleach, or harsh chemicals as these can break down the material,
  
• Replace your chewie when it gets worn out, or when it gets flat or have cracks in it. A worn-out chewie won't apply even pressure and should be discarded.
