Perform prophylaxis of the teeth, leaving the tooth surface free from biofilm. Select and record the patient’s teeth shade with a shade guide and/or photograph prior to starting whitening.

Proceed to the insertion of the Arcflex (FGM) lip retractor, to facilitate access and handling of the buccal cavity, and then apply Desensibilize KF 2% for 10 minutes on the teeth that will be whitened.

After applying the desensitizing agent, remove the gel and dry the teeth and gums with air jets. Make the relative isolation by applying the light-curing resin Top dam (FGM).

With the auto mixing tip coupled to the double-body syringe that contains the whitening gel, press the plunger until the phases (peroxide and thickener) are slowly mixed. A small quantity of gel should be dispensed into a container prior to applying the product to the patient’s teeth. It will assure that the applied product is properly homogenized.

Directly apply the gels to the teeth to be whitened, generally from the 1st or 2nd premolars to the other. Cover the vestibular face of the teeth with a gel layer as thin as possible, using the auto mixing tip to spread the product. The gel may be extended to the small incisive/occlusal surface area of the teeth. If you wish to use a light source device, start using it shortly after applying the gel. For each equipment, there is a specific protocol of light exposure time. Follow the manufacturer’s instructions for the light application time, however, observe the time protocol to apply the product onto the teeth.

After applied, the gel must be left in contact with the teeth for up to 50 minutes, during which the professional may move the gel with a probe or disposable micro applicator, such as Cavibrush (FGM), in order to remove the air bubbles and renew the contact between gel and teeth. There is no need to change the gel during the session. Note: application times for whiteners are only suggested and must be managed by the professional. Shorter times or treatment interruptions may occur in cases of dental hypersensitivity.

At the end of the session, remove the gel with the thin suction cannula, and wash the teeth thoroughly. Removal of the gum dam may be performed with a probe or similar.

Polish the teeth with the Diamond Excel (FGM) polishing paste, and Diamond (FGM) or Diamond Flex (FGM) felt disks.

The patient should return after 7 days, allowing the effective assessment of the tooth’s shade. If required, further whitening sessions may be performed according to the above steps. In general, we recommend 2 to 3 whitening sessions to achieve good results.
