Aligners can only move teeth effectively if they fit snugly against every tooth. Even small gaps between the aligner and the tooth can slow progress or cause teeth to fall off track. Aligner chewies are a simple, inexpensive tool that helps press trays fully into place. Used correctly, they can make a real difference to your results.
Chewies are small, soft cylinders made of a rubber-like material. You place one between your teeth and bite down gently, moving it around the mouth so it presses each part of the aligner onto the teeth. They do not dissolve or contain sugar. Many patients receive them at the start of treatment, and replacements are inexpensive.
Aligners work by applying gentle, precise pressure to specific areas of each tooth. If the tray does not sit fully down, that pressure is not delivered as planned. This is particularly important around attachments and for teeth that need to rotate or move vertically. Proper seating also helps your mouth adjust faster to each new tray.
After inserting your aligners, bite on a chewie for around five to ten minutes, moving it from the back teeth to the front on both sides. Focus on areas where the aligner feels loose or where you see a gap. Many dentists recommend using chewies a few times a day, especially in the first days of each new tray and after meals when you reinsert aligners.
Look for visible air gaps between the edge of a tooth and the aligner, particularly on the biting edges of front teeth. Other signs include an aligner that clicks or lifts when you speak, attachments that are not filled by the aligner bubble, or a tray that feels loose when it should be tight. Check in a mirror after inserting each new set.
If gaps remain despite chewies, do not move on to the next tray. Contact your dentist, who may advise wearing the current tray for longer, using chewies more often, or adjusting the plan. Moving on with an unseated tray can increase the gap and lead to the need for refinements.
Rinse chewies after each use and let them air dry. Replace them regularly, as they can harbour bacteria and lose their springiness over time. Keep a spare in your aligner case so you can use one after lunch at work or school.
Wear aligners for 20 to 22 hours a day, switch trays as instructed, and keep attachments intact. If an attachment breaks off, contact the clinic, because aligners rely on them for grip. Small daily habits like these add up to more predictable, efficient treatment.
They are not always essential, but many dentists recommend them because they help aligners seat fully and improve tracking.
Usually five to ten minutes, a few times a day, especially when starting a new tray.
No. Chewing gum with aligners in can stick to them and contains sugar or sweeteners. Use proper chewies.
