We put Snow's Teeth Whitening Kit With LED Light to the test after receiving a complimentary sample from the brand. Keep reading for our full product review. 

When I was in high school, I had my first introduction to a teeth whitening kit. This was back when Crest Whitestrips were all the rage. I like the idea of them—simply slap a strip on your teeth for a few weeks, and you’ll have whiter teeth—but I was not too enthused when it came to the side effects, like sore gums and sensitive teeth (to me, there’s nothing worse).  

When I heard about the Snow Teeth Whitening Kit With LED Light, I was excited. Thanks to LED technology and a specific whitening formula, my teeth would get brighter and whiter without any of the side effects—or so I was promised. Here’s how it worked out for me. 

Snow Teeth Whitening Kit With LED Light

Uses: Teeth whitening

Potential allergens: Hydrogen peroxide and carbamide peroxide

Active ingredients: Hydrogen peroxide and carbamide peroxide

Byrdie Clean?: Yes

Cruelty-Free?: Yes 

Price: $150

About the brand: Snow is an oral care company that sells a high-tech, award-winning teeth whitening serum.

About My Teeth: White in the front, yellow-ish in the back, and a little crooked 

Proper dental hygiene is incredibly important to me. Bad breath is my pet peeve, as is getting cavities—which I’m very prone to—so I make sure to brush for two minutes twice a day with an electric toothbrush, floss every night, and visit the dentist for a cleaning twice a year. 

As for my teeth color, I use a gentle whitening toothpaste (Sensodyne) and my teeth tend to be whiter in the front and get yellower on the sides and in the back. They’re also a little crooked—I was that kid who by some miracle of genetics never needed braces, but I’m now considering Invisalign (or a less expensive similar brand) to fix a cute little snaggletooth I’ve developed. 

The Feel: Smooth and didn’t leave a residue 

With traditional white strips, I recall a grainy feeling and an aftertaste that would linger in my mouth for hours afterward, and it didn’t help that—at the time at least—the instructions said I should not rinse out my mouth after use. 

That was not the case at all with the Snow Teeth Whitening Kit. The bundle comes with a whitening gel, which comes in the form of a pen (it reminds me of some lip glosses I used to use as a teenager, the ones where you twist the bottom and gel emerges from the top on a little brush).

You can control how much you use and where you apply it—I chose to put more on the sides, as that’s where my teeth are yellower—and I could avoid getting it on my gums.

The gel is also very smooth and doesn’t leave residue or an aftertaste. Another great thing? I was allowed to lightly rinse out my mouth after use. From a “feel” perspective, though, one thing to note is that while using the LED light, my saliva got a little…hot. So when I swallowed, I was swallowing warm saliva. Yes, it was kind of disgusting.  

Side Effects: None—yes, really

The Snow Teeth Whitening Kit promises a gentler experience than other teeth whitening kits. Read: No painful gums or tooth sensitivity, both of which I have absolutely experienced in the past. 

I know the drill: For a few days, everything feels great. Then day seven hits, and suddenly applying those little strips is excruciating—it calls to mind that awful phrase, “beauty is pain.”

I didn’t use the extra strength serum, which has a higher concentration of peroxide, but with the normal whitening wands, I really didn’t experience any adverse side effects.

But after 21 days of use, I didn’t have a single uncomfortable moment with this LED kit.

Packaging: It comes in a few parts, but it’s easy to get the hang of

When I first opened the Snow Teeth Whitening Kit, I was a little intimidated—what were all these cords and tiny metallic wands? Luckily, the instructions were very easy to follow, which was a relief for someone like me who is incredibly impatient when it comes to reading lengthy instructions.

Basically, the process of using the kit goes something like this: You apply the whitening gel to your teeth, put the LED mouth guard in your mouth, and plug it into one of your devices, at which point a bright blue light will turn on. The USB cord that’s attached to the mouth guard is compatible with basically every device you can imagine—I used it both plugged into my iPhone and my laptop.

The Results: Whiter teeth without the pain

At first, I didn’t see any major results with the Snow Teeth Whitening Kit. And as time went on and I didn’t experience the side effects I’ve had with other teeth whitening kits, I was doubtful that would ever happen. But about two weeks in, I noticed my teeth were a little whiter, and by week three they were a lot whiter. Not blindingly white, but whiter. 

So yes, this kit works. But you have to be patient: Full results take 21 days, according to the instructions, and this is the truth: It won’t happen overnight.

Another thing to note: You absolutely cannot talk while using the Snow Teeth Whitening Kit. The mouth guard will fall out of your mouth, and you’ll drool everywhere. My husband tended to pick the 20 minutes a day when I had my LED mouthguard in to ask me questions, at which point I had to text him the answer. So if you’re planning to whiten while in the company of others, let them know you will not be able to talk.

The Value: On the expensive side

The Snow Teeth Whitening Kit comes at a pretty penny. You can pick up basic Crest Whitestrips for $50 or splurge on this teeth whitening kit for around $150. As someone who takes oral hygiene and health very seriously, a pain-free experience that won’t damage my gums or teeth is worth the extra $100 to me.

Similar Products: There’s no question that this stands out

Crest 3D Whitestrips ($46): My only other experience with whitening my teeth has been with the ultra-popular Crest Whitestrips. I’ve used them a few times in my life, and I’ve never been the biggest fan of the experience, even if it yields whiter teeth in the end.

Although Crest Whitestrips are more affordable, the Snow Teeth Whitening Kit With LED Light stands out to me as a much more high-quality product and a better experience overall. I know that Crest has an LED option now, which may not be as uncomfortable, but I haven't tested it out just yet.

Final Verdict

If you want whiter teeth without the pain, spring for the Snow Teeth Whitening Kit With LED Light. You’ll end up with a brighter smile without the potential painful side effects and a bad aftertaste.
