If you prefer to whiten at home or want to continue the whitening process, we will create a set of custom-made trays which you fill at home with the GentleWhite® At-Home Formulation. We will take a careful impression of your teeth. Those impressions are turned into plaster molds of your teeth, which are used to create clear thin plastic trays, custom cut to fit your upper and lower teeth comfortably. Then, once a day simply apply a small amount of the gel in your trays, and slip them onto your bite for just 20 minutes a day, for five to ten days, to complete the bleaching process. It is convenient and effective.
