Your treatment will only work as well as it can if you wear your Invisalign tray for 22 hours a day. That gives you two hours without it, during which you can do all the things you can’t do with your Invisalign in. That includes eating and drinking any liquid that isn’t completely clear. Keep in mind that you have to brush your teeth between eating and putting your Invisalign back in, so it’s best to carry a travel toothbrush and toothpaste with you when you leave the house.
We also recommend that you carry a retainer case with you to hold the tray when it’s out of your mouth. Some people get tempted to take their tray out and wrap it in a napkin or paper towel, but this makes it too easy to accidentally throw it away. If that happens, you could find yourself in need of a new Invisalign tray. You also don’t want to have to deal with digging through the trash for something that’s supposed to go in your mouth.
