How Does Crest Whitening Work?

The Original Whitening kit from Crest contains 14-treatments. You get the option of using the 3D whitening strips alongside the Crest whitening light to speed up your progress. The whitening compound on the strips contains a specialized formula, featuring peroxide as the primary bleaching agent for your teeth.

You attach the strips to your teeth and then bite down on the blue light device. Activate the whitening light, and wait for ten to 15-minutes for the treatment to work. Complete this treatment once a day for two weeks, and you'll be on your way to a brighter, whiter smile.

We recommend brushing your teeth before using the Crest Whitening Strips. The built-in timer to the light device lets you know when the treatment is over. After finishing your whitening session, remove the strips and rinse out your mouth with water – don't brush your teeth again.

The Crest whitening strips and light come as a complete kit. The batteries in the light device have enough power to get you through the 14-day treatment. After finishing your treatment, you'll need to throw away the light device (please remember to recycle!)

How Do I Start with Crest Whitening?

You can get a Crest whitening boost by ordering your whitening strips on the website. The shop section of the site offers the Original Whitening Kit for $70, which we feel is somewhat expensive than other similar whitening products.

The Express Whitening Kit sells for $75 and promises faster results. The Crest strips are available for use without the blue light device. You get a set of 3D whitening strips and eight fee Express Whitening Strips included in your package.

The Gentle Whitening Kit is the better choice for users with sensitive teeth. It sells for $70, which is above the average selling price for most whitening systems, and you get a light device included with the kit.

The 3D Whitening Strips come in an original flavor and Arctic Mint and Charcoal Mint flavors. Overall, the Crest Whitening Kit is about $10 more than other offerings like the Novashine kit.

What Do Reviews Say About the Crest Whitening Kit?

According to Crest whitening light reviews, the system does work, producing noticeable results after a few days of use. However, there are reports of teeth and gum sensitivity. Crest does manufacture a "Gentle" whitening kit for people with sensitive teeth, but we feel it might be the overuse of peroxide causing these issues.

Still, the company has plenty of positive reviews online, with Reddit users stating the whitening system works. Choose the kit that suits your lifestyle, and start your journey to a brighter, whiter smile.

Crest Whitening Light Reviews – Is It Worth It?

Overall, the Crest whitening system provides some good results. We think it's not as effective as the Other offerings from leading brands like Novashine.

We don't like the disposable light device and feel this is a waste of money and materials. There are some reports of sensitivity in the teeth and gums after using Crest 3D Strips.

We also find it annoying that the strips don't cover all your teeth. Crest claims it only wants to whiten the teeth visible to other people. However, it does work, and the Crest whitening strips helps to remove stubborn stains.

Can I use blue light with regular Crest white strips?

Yes, you can use the blue light with the regular Crest whitening strips.
