If you’ve run out of Invisalign chewies or just want a different option, several alternatives work just as well for pressing your aligners snugly against your teeth. The goal is simple: apply even biting pressure for 5 to 10 minutes a day to eliminate air gaps between the plastic and your teeth. Anything firm but slightly yielding can do the job.
Why Seating Your Aligners Matters
Chewies exist to solve a specific problem. When you pop in a new aligner tray, it rarely sits perfectly flush against every tooth right away. Small air pockets form, especially around the biting edges and near attachments. Those gaps mean the aligner isn’t applying force where it needs to, and your teeth won’t move on schedule.
Biting down on a chewie (or a substitute) pushes the aligner tight against each tooth surface. This also stimulates blood flow in the gums, which helps teeth shift more efficiently and can reduce soreness. Without proper seating, you risk tracking problems, where certain teeth fall behind the treatment plan. Minor tracking gaps under 1mm can usually be corrected with better seating habits, but gaps over 2mm across multiple teeth often require a full rescan and new trays.
Commercial Alternatives
Movemints
Movemints are edible mints shaped specifically for biting down with aligners in place. You chew on them until they dissolve, which takes a few minutes. They contain a therapeutic dose of xylitol, a sugar substitute that fights tooth decay and dry mouth, both common concerns during aligner treatment. Since they’re single-use, you don’t have to sanitize or store them afterward. Many users find them more pleasant than gnawing on a piece of silicone, and the minty flavor is a bonus when you’ve had trays in all day.
Munchies
Munchies are silicone chewing devices similar to chewies but available in different firmness levels. If standard chewies feel too soft or too firm, Munchies let you pick the resistance that’s most comfortable for your teeth. They’re reusable, like chewies, and work the same way: bite down, hold for a few seconds, move to the next section of teeth, repeat.
DIY Household Alternatives
You don’t necessarily need a product marketed for aligners. The key properties are: firm enough to create pressure, soft enough not to crack your trays, and clean enough to put in your mouth.
- Rolled-up washcloth or paper towel: Fold a clean, damp washcloth into a thick strip and bite down on it section by section. A tightly rolled paper towel works too. Neither will damage your trays, and they create enough resistance to push the aligner into place.
- Cotton rolls: The kind you get at the dentist’s office. They’re inexpensive, available at pharmacies, and provide a consistent, soft surface to bite against.
- New pencil eraser: A clean, unused eraser on the end of a pencil gives you a small, firm surface you can press against individual teeth, especially useful for targeting a specific spot where the aligner isn’t sitting flush.
Avoid anything too hard. Biting down on a pen cap, hard candy, or a rigid object can crack the aligner tray or damage attachments. The material should compress slightly under your bite.
How to Use Any Seating Device
The technique is the same regardless of what you’re biting on. Start at one side of your mouth, bite down firmly for 3 to 5 seconds, then move to the next group of teeth. Work your way from one side to the other, covering the front teeth in between. Spend extra time on any spots where you feel the aligner lifting or where you can see a visible gap between the plastic and your tooth.
Aim for 5 to 10 minutes per session. Some orthodontists recommend doing this twice a day, especially during the first day or two of a new tray when the fit is tightest. After that, once a day is usually enough to maintain good seating. The most important time to use a seating device is right after you put your aligners back in following a meal.
Signs Your Aligners Aren’t Seating Properly
Even with consistent chewie use (or substitute use), aligners sometimes don’t track correctly. Watch for these signs:
- Visible gaps between the aligner edges and your teeth, particularly near the biting surface
- Rocking or floating where the tray doesn’t feel snug on certain teeth
- Uneven pressure with sharp discomfort concentrated on a single tooth instead of gentle, distributed tightness
- Attachments losing grip where you can see a gap between the plastic and a tooth that has a bonded attachment
- Individual teeth stalling where some teeth appear to move while others stay put
If your aligners won’t fully seat even after firm biting pressure and consistent use of a seating device, that’s a sign something beyond a chewie substitute can fix. The same goes for sudden sharp pain in one tooth, a cracked or torn tray, or attachments that pop off, especially on canines or molars. These situations call for a check-in with your orthodontist. Sometimes teeth are simply more stubborn than the software predicted, and a midcourse correction with new scans is the fix, not more aggressive chewing.
