Yes. Simply pat the teeth dry with a tissue prior to bleaching.

Remove the syringe cap; place the static mixing tip on and twist until it locks into place. Slowly dispense gel onto a tissue until the gel turns light blue. Dispose of the tissue. Once gel emerging from the syringe tip is light blue, begin to fill the dental trays. After the gel is applied to your trays, remove the static mixing tip and replace the cap until your next treatment.

The gel will not harm you in the quantities swallowed. We do not recommend sleeping with trays in your mouth. Traditional 2 hours per day, Duet & Forté are 30 minute applications.

Do not brush your teeth immediately before whitening, as this may cause discomfort to soft tissue and lessen the effectiveness of the whitening process. If brushing is done with fluoride toothpaste, the mouth should be rinsed well with water to remove as much fluoride as possible.

Kits should be refrigerated or stored in a cool environment. (Gel should be at room temperature before use).

Be careful of heat producing items such as lights that will increase the temperature of the kits. 
The shelf life of kits will be extended if kits are kept cool, below 50º F.

The kits have a self-life of about eighteen months, if kept cool.

Yes! Whitening your teeth by this method is permanent. However, depending on the amount of coffee, tea, wine and other stain causing food you consume re-staining may occur. You may wish to have a touch up every 6 - 12 months.

Fluoride affects the whitening process by inhibiting the release of carbamide peroxide, this in turn dramatically increases whitening time.

Equivalent Whitening Strength

Duet 22 ~ 15% Carbamide peroxide

Duet 30 ~ 18% Carbamide peroxide

Forté ~ 25% Carbamide Peroxide

When the gel is first placed into the mouth tray, the gel will be blue. As the gel is activating the gel will turn clear.

The gel used in the Duet system is stabilized carbamide peroxide that is mixed with an accelerating agent to speed up the whitening process while essentially eliminating tooth sensitivity.

Nu Radiance is traditional carbamide peroxide, which is a 2-4 hour process. We have provided this product to the Dental Industry for over 10 years. Nu Radiance Duet is a 30-minute sensitivity free formula, this dual syringe systems contains carbamide peroxide on one side and a hydrator and accelerator on the other. It is ideal for patients with sensitivity or who want to reduce treatment times.

What causes sensitivity during the whitening process?
 Whiteners are glycerin based which absorbs water from the teeth, thus disrupting the isotonic condition of the tooth causing sensitivity. In other words, the teeth get dehydrated during the whitening process, which causes the sensitivity.
