You cannot eat or drink anything other than water when you are wearing your aligner trays. However, you can eat anything you please after you take your aligners out. That’s one of the awesome benefits of Invisalign — unlike traditional braces where you can’t eat foods like corn on the cob or a caramel apple, there are no restrictions with Invisalign. You simply remove your aligner trays and eat whatever you want. Then when you’re finished (and have given your mouth a quick rinse with some water, if possible), you pop your aligner trays back on and you’re good to go.
