Life-Like endorses the Vita classic or the Vita 3D for shade assessment. It is important
that the patient takes an active role in this procedure. Example: Call out or announce
the shade number. Use a mirror and let them see the shade comparison.
We recommend this procedure to remove extrinsic stains and facilitate a greater
chance for a good seal when using a light cured paint-on dam.
Soft Tissue Protection:
Liquid dental-dam. Suggestion – use cotton swab to smear thin layer of vitamin E oil
approximately width of swab before applying liquid dam. This creates a nonstick
barrier for the soft tissue upon removal of dam.
Air dry the gingival area and apply the paint-on dam around one (1) or two (2) teeth at
a time and cure for 30-45 seconds with standard dental curing light or 15-20 seconds
with plasma arc light. Testing the dam with a light blast of air can help reassure a good
seal. If the air can get in then the hydrogen peroxide can too.
35% H202 and Enhancer:
When mixed these two chemicals react rather quickly so take steps to avoid mixing
them directly together in a dappen dish. Use assigned brushes for each to avoid cross
Avoid contact with soft tissue – use appropriate protection, gloves for clinician, and
safety glasses for both patient & clinician. H²O² is extremely caustic and will burn soft
You can use retractors or have patient rest teeth on a “bite-block” in molar region and
place cotton rolls into vestibule when using liquid dam.
For the lower arch: use saliva ejector and cotton rolls in the sublingual area to prevent
saliva from flowing on to the facial surface of the teeth.
By the end of the treatment the patient’s teeth will be dehydrated to some degree and
this will affect the ending results by providing a false shade. Option 1 – Informing the
patient that the teeth will rehydrate and the actual brightness will be accurate in a few
days. Option 2 – Recalling the patient in three to six days to assess the end result.
Follow up at-home:
In-office whitening should always be followed up with at-home bleaching trays of
carbamide peroxide in Life-Like’s Twist & Seal syringe for completion or touchup
Patient can be instructed to use at-home whitening for 3-4 days. Remaining bleach
can be used for future touchups.
Applying 35% H202 and Enhancer:
Place 12-14 drops of #9 enhancer* into a dappen dish. Express
approximately 1-2cc of 35% H²O² gel into a separate dappen dish. Use a
separate brush for each to avoid cross contamination. Air-dry area to be
Paint each tooth surface with #9 Enhancer. Air-dry to remove excess
enhancer with dry cotton roll or 2×2.
Paint thin coat of the 35% H²O² gel on the tooth surfaces, avoiding soft
tissue. Bleach should remain on tooth surface for 10 minutes.
Remove any gel with low vacuum & wipe with end of a cotton roll or 2×2.
4 times or until desired shade is achieved.
Topical application vitamin E oil.
Seal teeth with a standard ACP or fluoride.
