No, you definite cannot chew gum with invisalign.It is better not to chew gum at all.
Why? Because the pressure of chewing gum can dislodge the existing fillings or fixed prosthetics that you have in the mouth.It can reduce the salivary flow which is detrimental for the good oral function.
No snacking between meals with Invisalign
Another weight loss strategy today, besides South Beach or the Zone, is Invisalign treatment. Many people snack between meals so starting Invisalign care can be a challenge. The only thing that can be done while while wearing aligners is drink water, so this excludes coffee, soda and even chewing gum.
Do not chew gum with invisalign
I would advise against chewing gum with invisalign in your mouth. If you want to seat the aligners better, then use the aligner chewies a few times a day.
Chewing gum with Invisalign: not advisable
The cause of most less-than-ideal Invisalign results is not wearing the aligners full time. So taking them out to chew gum is not a good idea because it gets you in the habit of taking them off. Chewing gum with the aligners in place is not advised because the gum may stick to the aligners.
Chewing gum while using aligners
I would not recommend chewing gum while wearing aligners. The gum could potentially stick to the aligners. Ideally you should not eat with aligners in your mouth and drinking should be limited to water when you are wearing them.
Chewing Gum with Invisalign
Invisalign aligners are not meant to be used with chewing gum. It will stick to them and make a bit of a mess.
