It is imperative to wear your Invisalign trays at least 22 hours a day. Remove the trays only when eating, brushing, and drinking (anything other than water). Wear each tray for a minimum of two weeks. If the trays feel loose, still wear until the end of the two week period. If you miss a day, pick up where you left off and make sure you’ve worn for at least 14 days. When removing your trays, be sure to always put in a case. Brush your teeth and trays before placing your trays back in your mouth.
