I Tried the Viral At-Home Snow Teeth Whitening Kit: See My Results (2024)

A bright smile can light up a room, but keeping teeth white often takes a little extra effort —especially for coffee and red wine lovers. At-home whitening kits are effective, but many get a bad rap for causing sensitivity and discomfort. That’s where Snow stands out: the popular brand's gentle products are designed to be safe for sensitive teeth and gums and they're a hit on TikTok, where users say that while they may not whiten your teeth multiple shades instantly, they also don't cause pain or stinging.

To see what the buzz is about, Good Housekeeping Institute Beauty Lab Analyst Chiara Butler put one of their newest kits to the test.

What is Snow Teeth Whitening?

Snow offers two kits to choose from, the DiamondSeries Teeth Whitening Kit with Hydroxyapaite & Potassium Nitrate and the DiamondSeries Wireless Teeth Whitening Kit with Hydroxyapatite & Self-Sanitizing Charging Case.

Butler tested Snow’s wireless system, which includes a wireless LED mouthpiece, a whitening serum, a UV self-sanitizing case and a teeth shade guide. The mouthpiece features triple-LED technology, which the brand claims uses blue light to activate the whitening serum, helping to remove stains faster and potentially providing longer-lasting results.

The whitening serum relies on key ingredients hydrogen peroxide and carbamide peroxide, along with peppermint oil for flavor. “Peroxide gels break down into water, oxygen and reactive oxygen molecules,” explains Sophia Nichols, D.M.D., a dentist in Brick Township, New Jersey. “These reactive molecules treat the enamel and dentin, oxidizing stain molecules to lighten the teeth.”

According to Dr. Nichols, teeth whitening depends on how long peroxide stays in contact with teeth, rather than the LED light itself. While the light may help activate the gel and speed up the reaction, it doesn’t guarantee longer-lasting results. “How long the results last depends more on the patient’s diet and lifestyle, which can re-stain teeth over time,” she adds.

How to use Snow Teeth Whitening at home

The kit included clear instructions on best practices, but even without a guide, the process is straightforward. After brushing her teeth with regular toothpaste, Butler applied the whitening serum to her teeth using the brush applicator. "The serum was very easy to apply, and I didn’t feel any stinging on my gums or taste the serum, which was great," she says.

Next, she activated the blue light on the mouthpiece by pressing the power button and placed it in her mouth. She left it in for 10 minutes, though it can be used with the serum for up to 30 minutes. "The mouthpiece felt a bit heavy because of the battery at the front, and I noticed some tension in my bite while holding it in place," Butler shares.

Afterward, she removed the mouthpiece, rinsed it with water, and rinsed her mouth. She noted significant saliva buildup, which is why she kept her whitening session to 10 minutes. "There’s also a Diamond Series kit with a wired version of the mouthpiece, which might be more comfortable," she adds. The instructions recommend avoiding food and drinks for 30 minutes post-treatment.

Does Snow Teeth Whitening work?

The short answer is yes, according to Butler. "My teeth lightened by one shade after using it about three times a week for three weeks, and I’m a daily coffee drinker," she says. The brand recommends daily application for an initial 21-day period for optimal results, but Butler used the kit three times a week instead.

"It definitely works," says Butler. "My after photos show visibly whiter teeth, and I didn’t experience any sensitivity while using the kit." As someone prone to sensitivity after whitening gels, she appreciated the serum's protection and felt it truly made a difference. While it’s a pricier option, Butler found it worth the investment.

For a more budget-friendly alternative — especially for short-term whitening before an event — options like Crest Whitestrips or Snow's whitening strips are also great choices.
