How often do I need to wear my Invisalign trays?

In order to ensure that your Invisalign moves your teeth properly, your trays need to be worn a minimum of 22 hours a day. Invisalign trays should only be removed for eating, brushing and flossing. If you do have a day where you do not wear your trays as long as you should be, it is important to add additional time to the length you are wearing your current tray. For example, if normally you wear each tray for a week but have a day your trays are out more than two hours, make sure to wear that tray for a minimum of 8 days before moving to the next one.
