How to Seat Your Clear Aligners for Best Results
Great results come from patience and consistency. Here’s why the two-week schedule exists and what happens if you rush it.
Clear aligners work by applying precise pressure to specific teeth. If your trays aren’t seated properly, meaning they’re not sitting flush against your teeth, that pressure isn’t being applied where it needs to be.
This is especially important in the early stages of treatment, when your teeth are at their most misaligned and the trays may not snap perfectly into place on their own.
Simply biting down on your aligners usually only seats them in the back (molar area). The front teeth, where most of the visible straightening happens, often need a little help.
Aligner chewies are small, soft cylinders made from a spongy material called Styrene Copolymer. They look like a small roll of gauze.
Their job is simple: help close any air gaps between your aligners and your teeth so your trays fit as tightly as possible.
Some aligner companies include chewies in your patient aligner box. If yours didn’t come with any, ask your provider or order them online.
Chewies are reusable, wash with mild soap and water after each use
Replace them when they lose their bounce and elasticity
Tip: If your chewie is large enough, cut it in half, now you’ve got a spare
Place the chewie between your teeth (either lengthwise or widthwise, both work)
Bite down firmly and then release
Move it across your entire mouth, bite up and down from one side to the other, covering every tooth
Repeat 2–3 times across the full arch
Do this every time you reinsert your aligners, after eating, brushing, or any time you’ve had them out
Pro tip: Make it a habit to chew on your chewie for at least one full minute before bed. This ensures your trays are fully seated while you sleep, your longest continuous wear period.
Small habits make a big difference. Proper seating, consistent wear, and following your provider’s guidance are the keys to a great result.
