If Invisalign Chewies Are Not Used Everyday, Will Alignment Be Dramatically Delayed?

The most important time to use the chewies with Invisalign is when you start a new set of trays. The purpose of the chewies is to make certain the aligners are fully seated so that they allow for the optimum movement of your teeth. It is not important and necessary to use them everyday as long as the trays are seated properly but when changing to a new set of trays, the chewies will help the aligners seat best on your teeth to aid in achieving the best possible tooth movement.

Chewies are prescribed only when the aligners
are not tracking well. You should use them as directed to help the aligners fit
properly. If not used daily, you may need a refinement scan in order to finish
your case.

Short Answer: It is not likely that slackin with your chewies will do anything dramatically.

Long Answer: You doctor has chosen those for you to help insure you get the most out of your treatment as possible. I don't carry them in my office. As far as I know Align recommends biting on hard things approximately 30 min a day can be beneficial. Squeezing and holding the squeeze. NOTHING replaced good wear. I don't feel fingers are forceful enough, though better than nothing. Pens or hi lighters are effective also.
