How many hours a day do I need to wear my Invisalign?

In order to ensure that your Invisalign moves your teeth properly, your trays need to be worn a minimum of 20-22 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 wear your current tray.
