No  more than 2 g of gel per tray or approximately  40%  of tray capacity should  be  dispensed. The use of a saliva ejector  during  the  procedure  is recommended. Following  the procedure, the  patient  should  be instructed not to expectorate. When utilizing custom individually fitted trays, utilize only 5-10 drops of products per tray.
