Is CO. by Colgate Safe and Reliable?

CO. by Colgate says their SuperNova teeth whitening device has been rigorously tested and is 100% safe for consumer use. It won't harm gums or tooth enamel. Likewise, the whitening serum is safe to use.

The formula has a low peroxide concentration to minimize the risk of sensitivity. Contact with gums should be avoided to reduce irritation.

How CO. by Colgate Works

The SuperNova At-Home Teeth Whitening Kit comes with an LED teeth-whitening mouthpiece and a whitening wand containing a 3% hydrogen peroxide serum. Hydrogen peroxide is a whitening agent that can safely eliminate stains in teeth. 

When the LED teeth-whitening device is turned on, LEDs give off a specific wavelength of light, making tooth stains more receptive to the hydrogen peroxide. 

According to a study published in the Journal of Conservative Dentistry, laser, halogen, and LED-light activation produces increased lightening of tooth shade and longer-lasting results than non-light-activated teeth whitening.

How To Use CO. by Colgate's Whitening Kit

The rechargeable at-home teeth whitening kit is straightforward to use.

1. Make sure the device is fully charged before brushing your teeth. 

2. Pat teeth dry and apply the whitening wand to the top row of teeth. Wait ten to 15 seconds to let the serum dry. Repeat on the bottom teeth.

3. Insert the teeth-whitening device into your mouth and turn it on to activate the serum.

4. Wait ten minutes while the device is working.

5. After five minutes, the device will beep once to indicate it’s halfway done.

6. After ten minutes, two beeps indicate the process has finished.

7. Don't eat or drink anything for four hours after the treatment. Once this time has elapsed, brush your teeth.

Use the teeth whitening kit for ten minutes every day for ten consecutive days. The typical time between treatment cycles is three months, so you can use the SuperNova device up to four times a year to maintain a radiant smile. A good time to use the kit is in the morning after breakfast. Results could last up to six months.

Some people may experience gum discomfort or tooth sensitivity when using whitening products. However, CO. by Colgate assures that any discomfort you experience is temporary and not harmful.

Does the CO. by Colgate Actually Work?

Based on reviews we’ve read on websites such as Amazon and Home Tester Club, customers are impressed by how well SuperNova works, even on teeth that have been stained from years of tea and coffee drinking. Others have commented that the wand whitened teeth without causing sensitivity.

Colgate doesn’t offer a guarantee with the SuperNova, however, they state that you can expect the results to last four to six months. This varies depending on how frequently you smoke, drink coffee, or consume other things that might stain your teeth.
