Our 36% Carbamide peroxide teeth whitening gel refill comes with enough gel for approximately 10 treatments. You simply apply a very thin coat of gel to the fronts of the mouth trays on only on the parts of your teeth that show when you smile. That is generally about 1/2 mL per tray. But feel free to use more gel if you wish. It’s very gentle but effective and safe on your enamel!
