Teeth whitening is a bleaching process that lightens discoloration of enamel.

There is a small plastic disk underneath the batteries to prevent the light from turning on during shipment. Remove this disk and the light will work. The clear plastic disk can easily be missed, so look closely under the batteries.

If this is the case, you will have to purchase a new battery. These are called lithium coin cell batteries and can be purchased online or at a variety of supermarkets and convenience stores.

Teeth whitening products should not be used if you are under 18 years of age, are pregnant, wear braces, suffer from periodontal disease, tooth decay, jaw problems, irritable gums or teeth, colitis or any other health condition.

The whitening gel is placed into your custom fitted retainer, once inserted over your teeth the active ingredient in the gel starts to break down. Oxygen enters into the enamel and dentin which in turn breaks down the stain inside the tooth. The structure of the tooth is not changed, only the colour is made lighter.

Yes! Research and clinical studies indicate that whitening teeth with custom retainers using our formula is safe for healthy teeth and gums. However, always follow the directions and do not exceed the recommended treatment duration.

Results can vary, teeth whitening can show dramatic results in just a few days. Most people will see a substantial improvement within 1-2 weeks.

Once you have whitened your teeth, your teeth should always be whiter than they once were. However, as we continue to go about our day-to-day life, our teeth will start to stain again. To keep them white all the time we recommend repeating the treatment every 3-6 months, or regularly using a teeth whitening toothpaste or whitening pen.

All whitening gel should be stored in a dry cool environment. Generally the shelf life of most teeth whitening products is approximately 12-24 months. However, the potency of the whitening gel should still remain effective for a couple of months past this date.

All you need to do is place a continuous line of gel half way up on the inner side of outer wall of the retainer so that it forms a rope-like line of gel. When you place the retainer over the teeth, the teeth will displace the gel to cover the tooth surface.

The white spots are minor hypo-calcification spots. During the teeth whitening process, the chemical reaction of the peroxide breaking down generates some slight heat inside the tooth, and this heat causes the pulp and dentin to expand. This expansion pushes water out of the tooth. This is what we refer to as dehydration of the teeth. Some of the whitening that you see is most likely initial dehydration, not actual whitening. This usually lasts around 72 hours.

All whitening gel causes some degree of tooth sensitivity. This is discomfort due to hot and cold fluids, and sometimes even air. This is normal and an expected side effect. If your teeth do become sensitive, try completing the treatment every second day or reduce duration. Sensitivity should disappear completely within 1-3 days after completing the treatment. The You still achieve the desired results, it will just take a little longer. Gum irritation can also occur, especially if you overfill your retainer.You will notice that your gum will become white, however, this will disappear shortly after you stop your treatment. You can also place vitamin E oil on the affected area to reduce irritation.
