In This Review

Different factors cause teeth discoloration. It can happen due to a progression in age or what you consume and, at times, because of medical conditions or illnesses like liver or celiac disease. This discoloration is something reversible through different available options.

You can take care of any temporary discoloration caused by particular food and drinks by brushing and flossing. When it comes to intrinsic or severe discoloration, dental veneer placement is taken care of.

As for surface discoloration that has not gone too deep into the teeth, whitening strips can help remove the stains through bleaching. The bleaching agent (active hydrogen or carbamide peroxide) formulated into the product works by breaking down the stains on the teeth and restoring them to their white color.

Dr. Bill Dorfman, an aesthetic dentist, says, “Stains on teeth are not similar and therefore the type treatment and its effectiveness is dependent on type of stain.”

Overview of Crest 3D Whitestrips Smile

Crest 3D Whitestrips have been lauded as one of the best whitening products manufactured to eliminate stains and discoloration on teeth. The portable whitening kit has easy-to-use plastic strips that don’t require a professional to help you use them.

The plastic tubes are filled with the whitening gel that should be applied on teeth daily to whiten your teeth effectively. If used correctly and as recommended, the Crest 3D Whitestrips will give you results like a professionally done procedure.

How Does It Work?

Crest 3D Whitestrips, renowned as a top teeth whitening strip, feature a whitening gel that includes hydrogen peroxide or its diluted form, carbamide peroxide. When applied to the teeth via the strips, the gel initiates a breakdown process, effectively bleaching the stains and enhancing the teeth’s whiteness.

It would be best if you did not leave the whitening strips on for too long on your teeth; the recommended time is 20-30 minutes. Leaving the strips on for too long is most likely to cause more harm than good, as prolonged exposure to the contents in the strip will burn or cause gum irritation.

The 3D in the Crest Whitening Strips is meant to help get into crevices of your teeth, ensuring an even bleaching process that does not leave some spots not whitened. This technology is also meant to prevent and protect your smile from future staining.

To get optimum results from Crest Whitening Strips, you must use them properly per the recommended instructions. Following the proper steps ensures the Whitening Strips’ effectiveness and safety.

Breakdown of the Ingredients – Are They Safe And Effective?

Hydrogen Peroxide

Hydrogen Peroxide is an ingredient that is common and found in most whitening products. The concentration in the formula is 6.5% which is the correct quantity needed for breaking up the stains, as referenced in our Nubeam Teeth Whitening article.

According to Neil Hadaegh a dentist in Beverly Hills, “Hydrogen peroxide is the active ingredient in formulated into the whitening strip. He further explains that the percentage level of peroxide in Crest strips is safe and therefore recommends it.”

An article titled Tooth Whiteners – How is hydrogen peroxide used to whiten teeth explains how hydrogen peroxide works.

Polyvinylpyrrolidone (PVP) and Carbomer

PVP is an adhesive meant to help the strips stay in place on the teeth once placed. Carbomer is another chemical that works hand in hand with the PVP as another safe adhesive.

Acrylates Copolymer

This polymer holds the top and lower whitening strips together. It ensures they stay in place and don’t hinder your day-to-day activities when using them.

Sodium Hydroxide

This PH balancing ingredient evens out the acidic solution in the Crest Whitening Strips.

Sodium Saccharin

It is an alternative sweetener meant for dental health care products as opposed to regular sugar, which has more calories and might end up causing more damage. The primary purpose of saccharin is to improve the taste of the product.

EWG Skin Deep article evaluates sodium saccharin and alleviates any doubts on its safety and use in Crest Whitening Strips.

On the Crest website, additional information assures users of the Crest 3D Whitestrips safety, even with sodium saccharin as an ingredient.

Dr. Jessica Barron, a dentist at Barron Dental Family, states, “Despite sodium saccharin being sweeter than regular sugar, is not considered cariogenic, and therefore it is not classified as a “sugar.”

Happy Customer

One customer was happy with her results from using the 3D Whitestrips over two weeks.

Guilty Pleasure

Another loved the whitening strips so much that they have become their guilty pleasure due to the bright smile they gave her.

Great product, instant difference!

Strips are easy to use, and I could see a significant difference after using them a few times. I recommend it to friends and family.

Great Results!

I’ve been using the whitening strips consistently for a short period, and I can already see results! My confidence has been boosted, and I am happy to show off my fantastic smile. The fact that they stay on once placed is a plus since they don’t stop me from going about my day, which I love. I am happy with the purchase.

A few years ago, I stopped bleaching my teeth because the process would hurt my gums. Once I discovered these whitening strips, I felt no pain after using them, and the results were instant. – Vanessa

These strips always work wonders for me! About a year ago, our family dentist suggested I start using them, and I can’t see myself using any other product. ~ Ross

It Works!

Even though I brush regularly, my teeth were noticeably yellow. I don’t smoke cigarettes or drink coffee/tea, but I have sensitive gums. I used the product per the instructions on the box and noticed my teeth got two shades lighter. What surprised me was that I could use it on my sensitive teeth.~Caoilainn

I have thin and sensitive teeth and was worried these whitening strips would be painful by hurting teeth. Thankfully! They did not! I have off-white teeth and drink coffee daily. I love that the strips are easy to use, and the taste is mild.~ Patricia


Crest 3D Whitestrips with Light provides an at-home solution for whitening your teeth at a fraction of the cost you would spend at a dentist’s office and with less hassle. The ADA approves and accepts the whitening kit, and the positive review confirms its effectiveness.

The Whitestrips can damage your teeth and cause gum irritation and discomfort if not used as recommended. A change in the shades will vary from one individual to the other depending on the intensity of the stains.
