After extensive research and product testing, this article also underwent an intensive review process:
With over 1 million of their bestselling All-In-One Teeth Whitening Kit sold, Snow might be the internet’s favorite whitening kit. It also has endorsements from publications like Vogue, Allure, and GQ.
Snow was founded in 2017 by Josh Snow. His vision for whitening oral care with a 100% satisfaction guaranteed policy came to life with the help of the company’s lead medical advisor, Dr. Brian Harris.
The brand’s offerings range from toothpaste to electric blue light toothbrushes and lip care. Snow is committed to aiding the 18 million American children without access to dental care.
Snow relies on straightforward ingredients whose effects are compounded through blue light technology. Hydrogen peroxide, a classic whitening ingredient, delivers variable results depending on several factors.1
In addition, sodium bicarbonate is present in the kit’s serum, dispensed in controlled amounts, and painted onto the teeth. Also known as baking soda, this ingredient is naturally abrasive and great for removing surface stains from coffee, soda, and wine.
Sodium bicarbonate can be too abrasive for some teeth, wearing away precious enamel. This ingredient is best used in moderation, despite its zero waste efforts to replace toothpaste in collaboration with other ingredients.
Peppermint oil is another ingredient included to naturally improve the taste and smell of the whitening kit. This additive avoids pesky chemicals that might otherwise interact with the hero ingredients that make this kit so popular.
According to a study that evaluated the impact LED light has on whitening, effects are most noticeable upon first use versus over a sustained period.2 With this in mind, whitening the day before an event is best for vibrant results.
Another study points to how hydrogen peroxide interacts with sodium bicarbonate to promote teeth whitening. The combination is especially effective at removing surface stains on the exterior of teeth.3
Every Snow All-In-One Teeth Whitening Kit includes three wands of whitening serum, one wand of extra-strength whitening serum, and an original LED whitening accelerating technology mouthpiece with an adaptor that suits several devices for power.
Start your whitening process by brushing thoroughly for two minutes:
It’s important to note that Snow’s products are safe for dental restorations, including fillings, veneers, crowns, bridges, and implants. But keep in mind that restorations will not whiten.
I used the Snow All-In-One Teeth Whitening Kit three times, though the results were visible after my first 10-minute session. The images below are the before and after of my smile.
As with most whitening kits, Snow advises brushing teeth before applying whitening serum. I brushed for two minutes before removing the whitening pen and mouthpiece from the kit. Snow advises usage from 10 to 30 minutes and as frequently as once a day for expedited results.
The blue light mouthpiece comes with multiple adaptors that plug into various devices. I plugged the mouthpiece into my phone and set a time for 15 minutes. Unlike other devices, this at-home whitening kit does not shut off automatically. It must be unplugged from the power source.
The mouthpiece doesn’t have a ridge for teeth to rest comfortably on and is quite round. Despite the slight discomfort, I committed to the allotted time. Then, I rinsed my mouth, rinsed off the mouthpiece, and dried it before placing it back in the box.
Though Snow formulates its products with sensitivity in mind, I noticed an increase in tooth sensitivity when I used the product too close in succession. Taking a break for a few days and keeping sessions to 10 minutes helped prevent sensitivity.
This whitening kit has a helpful shade guide for actual data to back up the gradual whitening effects. Matching your teeth’s natural shade is an essential start. From there, track your progress gradually to find a cadence that makes using Snow’s All-In-One Teeth Whitening Kit work for you.
After using it three times, I saw my teeth lightened by two shades. Using the whitening solution too often created the slightest bit of sensitivity in my teeth, so I’ve since adjusted to whitening once a week. This ensures the color of my teeth stays relatively the same.
Results were visible after my first 15-minute session with the whitening kit. The brand encourages users to test different durations between whitening to find what feels best for their teeth.
Before trying Snow’s Teeth Whitening Kit, the edges of my bottom teeth appeared a little yellow from coffee and tea consumption. I was very satisfied with the brightness I saw after only three uses.
As far as cost per use, Snow’s All-In-One Teeth Whitening Kit comes out to less than $2 per whitening session, a steal compared to other at-home kits. Being able to start whitening without locating batteries was also a plus.
While shopping on a budget, those looking for a sustainable solution to their whitening needs should consider Snow. It’s especially great for those looking to incorporate a daily routine before an event.
