Take the teeth shade so that the dentist and the patient can have a comparison parameter for the whitening. Recording of teeth shade can be made using a shade guide or a photograph.

Molding: molding can be made with alginate and must properly copy all teeth that will be whitened.

Mold is made of stone-gypsum, in order to prevent bubbles. It is not necessary to relief the model to create gel shells.

Place the 1mm acetate plate Whiteness Plates for Molds (FGM) into the thermal laminator until forming a slight bending due to the heat. Then, pull the plastic state plate over the gypsum model, so the suction can thermal format the mold into the model. The plate’s removal must be made after it has fully cooled down.

After removing the mold from the model, trim it to cover 1 to 2mm of the gums margin.

Mold test: the mold must not compress the soft tissue, nor present excessive gaps.

Show to the patient the quantity of gel that should be applied to the tray. One drop of gel must be put into the areas corresponding to the vestibular faces of the teeth that will be whitened. Wearing time: 2 hours per day for 4% concentration; 1 ½ hour per day for 6% concentration; 1 hour per day for 7.5% concentration; and 30 minutes per day for 10% concentration.

Monitor the patient weekly until completing the treatment. Record the final shade achieved.
