Are your teeth starting to show stains or an increasingly yellow hue? White Light Smile promises to help you get the smile you deserve within days—and without painful procedures or the expense of visiting your dentist.

This As Seen On TV product claims to represent “the future of teeth whitening.” However, it’s our experience that ASOTV brands are prone to making big promises while delivering somewhat disappointing results.

To determine if White Light Smile can help your teeth have a brighter future, let’s take a look at how the product works, along with some of their claims.

How Do You Brighten Teeth With White Light Smile?

Using White Light Smile appears to be simple: You squeeze some gel onto a mouth guard-like device before popping it in. You then turn it on and “sit back to relax.”

What are you turning on? The handheld device incorporates blue LED lights that literally light up your smile—at least temporarily.

While we’re not told much about how the White Light Smile works on the product’s official website, their promotional video shows that the LED lights illuminate a user's teeth after the whitening gel is applied.

As we’ll mention several times, the official website for White Light Smile comes up heavy on claims, and light on actual information. One of the facts that’s left out is how long White Light Smile is supposed to be left in your mouth.

To find actionable information about how White Light Smile is used, we had to search through customer reviews. According to Thrillist’s test run, the device is supposed to be held in place for ten minutes.

Thrillist writer Jeremy Glass shares another bit of important information left off of White Light Smile’s official website:

What’s in White Light Smile’s Whitening Formula?

According to their review, “the contents include your typical mishmash of ingredients you'd find in most home bleaching kits: glycerin, carbamide peroxide, hydrogen peroxide, povidone silica, carbomer, and sodium peroxide.

Carbamide peroxide is a common ingredient in teeth-whitening solutions—a fact that doesn’t bode well for White Light Smile’s claims of delivering “the future of teeth whitening.” It’s composed of equal amounts of hydrogen peroxide and urea.

The good news is that carbamide peroxide is commonly used because it’s known to effectively whiten teeth. Once exposed to oxygen, the compound dissolves and can have a bleaching effect on teeth, removing both deep and surface stains.

Be warned that carbamide peroxide can cause tooth sensitivity and soft tissue irritation. Generally, these products instruct you to rinse away a whitening solution before the risk of sensitivity and irritation become too great. However, if you become overzealous with your applications, you might experience discomfort for several days.

White Light Smile doesn’t disclose the concentration of their active ingredients. This leaves potential consumers clueless as to how effective the solution might be—or how safe. (We’ll share the concentration in professional whitening solutions shortly.)

Tip: One trick to lessen the potential risk of sensitivity is to rub Sensodyne toothpaste across teeth and gums before application, letting the paste sit for several minutes before rinsing, and again after.

Who’s Behind White Light Smile?

As we mentioned above, White Light Smile is sold as an As Seen On TV product as well as online. Brands under the ASOTV umbrella are often ambiguous when it comes to sharing who’s behind a product, and White Light Smile is no exception.

Consumers are told is that White Light Smile is the brainchild of “ten professionals”—though they didn’t bother to share what field. The logical assumption would be dentistry, but a little digging on another claim reveals that the brand is possibly not so trustworthy:


The brand claims to have over 15 thousand fans on Facebook. We could only find evidence of White Light Smile’s UK-based page—which shows a paltry seven fans. Maybe everyone else dropped off?

Considering thealmost totall lack of information available about the product or people behind it, our experience leads us to believe there might be something else afoot.

Why Does White Light Smile Leave Consumers in The Dark?

A more likely brand story is that White Light Smile isn’t the brainchild of ten professionals, but possibly a white-label teeth whitening kit, like this one available on

White-label products are essentially just that: they’re unbranded. Manufactured in bulk (and usually somewhere inexpensive, like China), white-label products are generally sold at rock-bottom prices. The catch is that you have to buy hundreds—or thousands.

This system allows companies to start up in a flash. All that’s left is to print branded packaging, put up a website for ordering, and start advertising.

But, in our experience reviewing cosmetics, white labeling also creates the opportunity for fly-by-night businesses to escape the consequences of shady practices or shoddy products. Too many negative reviews? Simply change the product’s brand name and start the process again.

What Are Customers Saying About White Light Smile?

We’ve already mentioned Thrillist’s trial of White Light Smile—what did they have to say about its whitening power?

Below before-and-after images comparing his smile, writer Jeremy Glass bluntly states “White Light doesn't work.”

Another White Light review made in 2005 on the blog Will’s Life is just as straightforward: “It looks cool like it will work, but it doesn't, so beware.”

Hmmm. Doesn’t anyone give White Light Smile a semi-positive review? We thought we might have found one, posted on, which rates the device a “5 out of 5.”

However, a closer inspection raised a few red flags:

  • The article claims that no chemicals are used, and that the light alone whitens your teeth.
  • Several paragraphs later, the article mentions carbamide peroxide as an ingredient, then claims the solution is one of a kind.
  • The writer links to Gym Junkies’ own Facebook page in a mention of White Light Smile’s 15 thousand fans.

While we can’t say for certain, it’s our experience that this kind of review is generally fraudulent. Instead of listing facts and researching ingredients, the review parrots promises made on the product’s official website and appears to be written as a kind of sneaky advertisement to make prospective customers believe that a product really works as claimed.

When searching for reviews of White Light Smile, it’s important to use a discerning eye to spot spam posing as an honest review. Not to say that every positive review of the product should be disregarded as suspicious. However, you should keep a lookout for articles that appear over the top.

What Professionals Say About Teeth Whitening Lights

It’s also worth noting that, while there are several different types of lights used during teeth bleaching, there’s no evidence that they are necessary to the process. The lights are supposed to work by triggering a light-sensitivity catalyst within the whitener that assists in breaking down the peroxide into its reactive components.

However, there’s increasing doubt that the lights used during bleaching speed up the process. According to The Truth about Teeth Whiteners, published by Boston University:

There are some products that use a light that we flash on our teeth to accelerate whitening. Even the whitening lights that we use in the dental office are no more effective than other ways of whitening teeth.

Unfortunately, White Light Smile doesn’t share which brand of light their device uses, so we’re not able to make a direct comparison to those found in a dentist’s office.

However, the BU professor being interviewed goes on to suggest that consumers searching for significant teeth whitening should stick to tried-and-true methods applied by a professional dentist since they have access to solutions with higher concentrations and the know-how to protect your gums during the process.

Bottom Line: Is White Light Smile a Scam?

Should you spend your money on White Light Smile? Before you start shopping, consider the following:

  • Generally, consumers have left overwhelmingly negative feedback for similarly-marketed teeth whitening products.
  • White Light Smile doesn’t share the concentration of their whitening solution, giving you no reason to believe that it will stand apart from the rest.
  • The light aspect of White Light Smile is likely ineffective and only there to make the device look like it’s doing something.

Due to the above factors, it’s our opinion that White Light Smile might fall short of delivering on their promise of noticeably whitening your teeth—especially within the proposed time frame of ten minutes.

And, don’t forget, the White Light Smile kit costs $116/ That’s almost seven times as expensive as whitening products sold by popular brands in your local store!
