Invisalign: How to Eat when Can't Brush Right Away?

Ideally, you want to brush and floss each time after you eat before you insert your aligners.  Realistically, that can't always happen.  Either rinsing your mouth with warm water or chewing sugarless gum for 20 minutes after a meal will help remove food particles and move them and the bacteria off your teeth.  If you need to reinsert your aligners after that, just brush and floss as soon as you can and make sure to clean your aligners as they probably picked up some of the particles from your last meal.

You should remove the aligners to eat and to
brush your teeth. If the aligners are not removed while eating it is suggested
that you brush your teeth and rinse the aligners immediately after eating.

I understand that it is not always convenient - or even possible- to brush right after eating. I recommend that patients rinse thoroughly with warm water to remove any large food particles, put their aligners back in, and then brush as soon as possible. If even rinsing cannot be done, it is OK to leave the aligners out for an hour or two, on occasion, until brushing and flossing can be done conveniently.I hope this is helpful!
