Place a small drop of whitening gel on a inner surface of the tray, in each tooth compartment, half way up.
Important: Overloading the trays with gel may cause tooth sensitivity and/or gum irritation.

Place the tray with the gel in your mouth. Seat the tray firmly against the teeth.

Extensive composite (white) & porcelain restorations


This gel will whiten natural teeth only. It doesn’t have effect on existing cosmetic restoration (bonding, crowns, bridges, veneers, inlays, onlays, fillings),their shade (colour) will not change.If darker they may need to be replaced to match the colors to your newly whitened color shade.

Severe gray/blue banded tetracycline staining


These grayish/blue stains can be harder to remove, if not impossible. These stains can take up to six months or longer to whiten. Whitening may only reduce amounts of 'masking'.

(clear, transparent) teeth

Temporomandibular Joint Disorders

Keeping Your mouth open because of the tray during the treatment could cause discomfort or pain if You have TMD.

Peroxide allergy

You will develop allergic reaction because gel contains peroxide

Severe loss of enamel

May cause sensitivity

Large pulps

May cause sensitivity

Exposed root portion due to a gum recession

This portion of a tooth will not whiten.

Children under 18 years of age

Whitening causes pulp damage


If You experience tooth sensitivity
or gum irritation  during the treatment …
…please discontinue the treatment for day or two, shorten the the treatment time, start using Sensodyne paste (or any paste that contains Potasium Nitrate) or start using Desensitizing gel-please ask us about this product). Mild sensitivity to cold is a normal side effect during this treatment.  If you experience continuous tooth pain or any other symptoms which are more than mild and/or persistant, please discontinue the treatment and call our office for further instructions. If you have any other questions or concerns, don't hesitate to call us and ask.

Additional information

Avoid citrus foods and juices because they can cause tooth sensitivity. These items change the acidity of your saliva and may cause irritation or slow down the whitening process. Try to Avoid any tobacco and dark liquids (coffee, tea, dark colas, dark juices and red wines) for at least 2 hrs after removing your trays and as much as possible while whitening because these substances may restain your teeth. Continue good oral hygiene throughout the treatment.
Eat, drink, or smoke while wearing your custom trays.

Storage of materials and trays

Storage at temperature between 2 and 8 Degrees Celsius (35-45 F) in a cool, dry place for later use once the whitening process is complete You may refrigerate remaining gel to lengthen the shelf life ( up to 2 years) but don't freeze.cDo not use after expiration date.

Keep it away from direct light . Keep whitening kit out of reach of children

Maintaining Your smile (Touch ups)

Depending on your teeth and your habits, these whitening procedures can last for up to five years. Deeply pigmented drinks like colas, tea, coffee, and red wine will tend to re-darken teeth more quickly. But, You can always do a “touch up” at a later date, using your trays for a couple of sessions to brighten your teeth again.The area of the tooth closest to the gums may take longer to lighten than the biting edge. It will also remain the darkest part of the tooth.

Whitened teeth will always be lighter than they were prior to the treatment and some clients will never need to repeat the process. If you notice that you are acquiring some stain, you may do a touch-up for a night or two every year.
