If you’re in the market for teeth whitening, chances are you’ve heard of Snow®. The brand has skyrocketed since its start in 2017 to an authority on all things teeth whitening.

I was eager to see if the Snow Whitening Kit could brighten my teeth, so I put it to the test. In this review, I’ll share my personal journey, including the changes and side effects I experienced with this product. You’ll get a clear picture of what it’s like to use Snow so you can decide if it’s right for you.

At NewMouth, we’re passionate about helping you achieve a perfect smile. That’s why our team is constantly trying out the latest teeth whitening kits. We find the safest and most effective options that deliver noticeable results without harsh chemicals or a hefty price tag.

Pros & Cons of Snow Teeth Whitening

After testing the Snow Whitening System, here’s what I think of it: 

What I Like About Snow

  • Fast and effective. I got the shade I wanted after just three treatments. You can get better results with a longer treatment and the extra-strength serum.
  • Affordable teeth whitening. Snow costs $1.80 per treatment, saving me $650 to $1,500 on professional teeth whitening.
  • Easy and convenient. It allows me to whiten my teeth at home without the need for dentists. The instructions with my kit were simple enough to follow.
  • Customizable to your needs. Depending on how bright you want your smile to be, you can adjust the frequency and length of each treatment.
  • Travel-friendly. The kit easily fits into any small bag for long trips. Plus, Snow gave me a free travel serum for quick on-the-go teeth whitening.

What I Don’t Like About Snow

  • May cause tooth sensitivity. Using Snow for three days straight made my teeth sensitive. Adjusting your treatment can help prevent this.
  • Needs some dedication. With each treatment lasting up to 30 minutes, you may want to multitask while the LED mouthpiece enhances your results.
  • Requires minimal cleanup. It isn’t completely mess-free. If you use the mouthpiece, you’ll have to clean it after every use.

What’s Inside The Snow Teeth Whitening Kit?

I bought the Original Teeth Whitening Kit for $69. My package arrived in the mail a little over a week after placing my order, just as I had expected.

It’s a small, solid box (about the size of a smartphone packaging) with a lid that slides off the top. It was wrapped in a thin cardboard slipcase.

Inside my teeth whitening kit were:

  • Two (2) silver teeth whitening serums
  • One (1) gold extra-strength teeth whitening serum
  • The SNOWLIGHT™ LED Accelerating Mouthpiece
  • An instruction booklet with a step-by-step guide
  • A transparent teeth shade guide for tracking your progress
  • A charging cord with four (4) adapters for different devices

The box looks simple, professional, and well-made. Snow’s products were secured with minimal waste. I think it’s great they used recyclable and biodegradable materials (cardboard) and didn’t use too much packaging.

Which Ingredients Are In Snow Teeth Whitening?

Snow’s whitening serum contains hydrogen peroxide, carbamide peroxide, and a combination of other ingredients that are safe for your teeth.1

It doesn’t have harsh chemicals or substances that are potentially harmful to your health, such as alcohol, bisphenol A (BPA), fluoride, and sulfate.

Before trying the product, I investigated the effectiveness and possible benefits of its ingredients. Here’s what I learned:

  • Hydrogen and carbamide peroxide ⁠— Dentists use both bleaching agents in professional teeth whitening treatments. They whiten teeth by breaking down the pigments that cause stains and discoloration.2,3,4
  • Glycerol — Allows whitening compounds to reach stains below the surface of your teeth (enamel). When used with carbamide peroxide, it speeds up the teeth whitening process.5
  • Aqua (deionized water) — Dilutes ingredients, making it easier to apply the product over your teeth.
  • Sodium bicarbonate (baking soda) — A mildly abrasive ingredient that removes stains from your tooth enamel.6
  • Carbomer — Thickens the teeth whitening gel and allows it to stick to your teeth, giving active ingredients time to penetrate the enamel.7
  • Potassium nitrate — Calms the nerves in your teeth and desensitizes them, reducing your risk for tooth sensitivity.8
  • Mentha piperita (peppermint oil) — Adds a refreshing and minty flavor.

While it’s common for cosmetic products like teeth whitening kits to be tested on animals, Snow uses a cruelty-free formula which I love.

Before & After: My Experience Using Snow

Before trying Snow’s Original Teeth Whitening Kit, the lower edges of my bottom teeth appeared a little yellow, probably because I regularly enjoyed drinking coffee and tea.

I used the silver pen and LED mouthpiece three times throughout my treatment since I didn’t want a drastic change. After the first application, it made my teeth whiter.

Here are before and after photos of my smile after the first session:

How To Use the Snow® At Home Teeth Whitening Kit

Before you use Snow teeth whitening, start your whitening process by brushing thoroughly for two minutes. Afterward, follow these instructions:

  1. Remove the Original LED whitening mouthpiece with its adaptable input cords. Set to the side after locating the power source.
  2. Remove a single wand of whitening serum, twist the bottom three or four times, and then paint the teeth in a stroke similar to painting nails.
  3. Place the LED mouthpiece in your mouth for the desired time, ranging from 10 to 30 minutes. 
  4. Rinse mouth and mouthpiece with water. Repeat the process as often as daily, if preferred. 

Snow’s products are safe for dental restorations, including fillings, veneers, crowns, bridges, and implants. But keep in mind that restorations will not whiten. 

Is Snow Teeth Whitening Safe to Use?

Snow’s teeth whitening kit is safe to use. However, they don’t recommend leaving the treatment on for over 30 minutes daily.

Teeth whitening is generally considered a cosmetic procedure. Therefore, whitening products may not be subject to FDA approval. However, people can protect themselves by following manufacturers’ directions and talking to their dentists.

If you have damaged or sensitive teeth, you may need to talk to your dentist before trying any teeth whitening product. You can also ask them for recommendations.

Snow® At-Home Teeth Whitening Kit Ingredients

Snow’s whitening serum relies on safe and effective ingredients whose effects are enhanced through blue light technology. Hydrogen and carbamide peroxide are trusted whitening ingredients that deliver variable results depending on several factors.1,2

In addition, the kit’s serum contains sodium bicarbonate, also known as baking soda. This naturally abrasive ingredient removes coffee, soda, and wine surface stains.

However, baking soda can be too abrasive for some teeth, wearing away precious enamel. This ingredient is best used in moderation.

Peppermint oil is included to improve the taste and smell of the whitening kit naturally. This additive avoids pesky chemicals that might otherwise interact with the hero ingredients that make this kit popular.

How Does Snow Teeth Whitening Work?

The Snow teeth whitening kit has a serum that acts as a whitening gel. It helps remove teeth stains so that you can achieve a brighter smile. After applying the serum, you use an LED light to activate the gel, accelerating the whitening process.

According to a study that evaluated the effects of LED light on teeth 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

My Experience

I used the Snow At-Home Teeth Whitening Kit three times, and the results were visible after my first 10-minute session. The images below are the before and after of my smile. 

Mouthpiece and Serum

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 doesn’t 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. 

Side Effects

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 to back up the gradual whitening effects. Matching your teeth’s natural shade is an essential start. From there, track your progress gradually.

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.

Overall Value

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 At-Home 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.

Pros and Cons

After using the Snow whitening kit, here’s what I think about the product:

What I like:

  • Easy to use – Using the whitening kit is pretty straightforward. The directions that come with the kit are very helpful and easy to follow.
  • Customizable based on needs/timing – Depending on how bright you want your smile to be, you can adjust your frequency of use.
  • Simple clean up – There’s no messy equipment to clean up after using the kit.

What I didn’t like:

  • Caused minor sensitivity – Using the kit made my teeth more sensitive, so I probably won’t use it as often anymore.
  • Thirty minutes per day for maximum results felt impractical – I didn’t really have 30 minutes a day to spend on teeth whitening. I’ll only use the product once or twice a week if I were to continue using it.

What Customers Are Saying

We also checked customer feedback as part of our Snow teeth whitening review process. The brand has a 4.65 out of 5 stars rating on the BBB website.

This means many customers recommend Snow teeth whitening because of their stellar customer service. Here are some other reviews for the Snow teeth whitening kit:

  • Customers have good experiences with the product’s effectiveness, noticing excellent results with minimal sensitivity
  • Many commend Snow’s customer service since they can quickly respond to inquiries 
  • Certain customers encountered issues with the blue light tool not functioning properly
  • Other people find the kit to be expensive, which can hinder them from receiving treatment

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.

Below is a more detailed breakdown of my experience with Snow, including:

  • My treatment results
  • Teeth whitening process
  • Side effects
  • Using it while traveling
  • My confidence and social media presence

My Treatment Results

Snow gradually and effectively whitens teeth. Mine became visibly brighter with the first treatment, but it was a subtle change. 

The shade guide helped me determine my current teeth shade (4) and the shade I wanted (2). You can use it to track your progress and match any discolored tooth to your natural teeth shade for an even smile.

It took me three applications to get the results I was after. The brand doesn’t have a fixed guideline on how long your treatment should last. You’ll want to try different things until you find what’s best for you, like:

  • Switching between regular and extra-strength teeth whitening
  • Wearing the LED mouthpiece for longer or shorter periods
  • Testing different treatment durations

For faster and more visible results: Use the extra-strength formula (gold pen) included with your Snow Original Whitening Kit. Try keeping the LED mouthpiece in your mouth for 30 minutes with each treatment.9

Teeth Whitening Process

Snow’s teeth whitening treatment is quick and simple. Each whitening session lasts 30 minutes to an hour, so I could easily fit it into my busy schedule.

It does require a bit of dedication. You’ll have to do it every day until you achieve the results you want. This could take days or weeks depending on how you adjust your treatment. Mine only lasted three days.

I did my treatments at night before sleeping, which Snow recommends. But you can do it anytime as long as you don’t eat for an hour after.9

My routine: For each treatment, I would brush for two minutes, rinse my mouth, and apply the whitening gel on my upper and lower teeth. I did this in front of a mirror to make sure that each tooth was adequately covered.

Next, I would plug the LED mouthpiece into my device and place it in my mouth. It doesn’t have a ridge for teeth to comfortably rest on. Instead, the device wraps around your teeth.

I wasn’t excited about this part of the treatment. While it wasn’t painful, the mouthpiece was bulky and felt awkward, especially with the wire. 

It does stay in your mouth and you’ll eventually get used to it. With a little creativity, you can also multitask while the LED lights are switched on.

I usually kept the SNOWLIGHT™ mouthpiece on for 15 minutes before unplugging and rinsing my mouth. Afterward, I would wash it with water, leave it out to dry, and return it to the box when I wake up in the morning.

Side Effects

Snow triggered my naturally sensitive teeth after three days of 15-minute treatments. However, it was a temporary side effect that went away after a few days.

Snow recommends re-applying twice a week once you achieve your ideal smile.9 But this made my teeth sensitive so I tried reducing it to once weekly, which worked perfectly for me.

Using It While Traveling

Snow doesn’t provide a travel pouch or a protective case with your kit. But its contents are small enough to fit into most bags and easy to carry around.

You can also spare yourself the trouble by using the free travel serum that Snow throws in with orders worth $30. (You should see it at check-out).

For on-the-go teeth whitening: The free travel serum works fine if you need quick touch-ups any time of the day. It has a maximum-strength formula, so you don’t need to use the LED mouthpiece after application.

I was able to use mine in my car and public bathrooms before important meetings and presentations. Just make sure you don’t eat for an hour.

For longer trips: I reused an old makeup kit with compartments to safely store my teeth whitening pens, mouthpiece, adapter, and compact mirror.

The adapters for the LED mouthpiece were a huge plus as I didn’t need to worry about batteries before the trip. I was able to plug into my iPhone and use it while I was in my hotel room or Airbnb. It should work on most smartphones, tablets, laptops, and powerbanks.

My Confidence & Social Media Presence

Seeing how effective Snow’s treatment was, I found myself smiling more naturally and worrying less about how my teeth looked.

It also gave me the confidence to post more on social media, a change that my family and close friends seemed to notice. I started getting more interactions in photos and videos where I smiled with my teeth.

Does Snow’s LED Mouthpiece Work?

Snow says the LED mouthpiece activates the ingredients in their teeth whitening serum “to give you a brighter smile within minutes”.9,10

Snow Teeth Whitening Kit Product Shot

While my treatment worked, I couldn’t tell if the LED light helped or if the serum’s ingredients worked on their own.

According to some studies, using light-accelerating devices with whitening treatment can produce better and longer-lasting results. Others say they can’t speed up or improve the effects of your treatment.”11,12,13

Is Snow Teeth Whitening Safe to Use?

Yes. Snow teeth whitening kits are safe for your teeth when used correctly.

At-home teeth whitening kits typically contain 3% hydrogen peroxide and 10% carbamide peroxide. These levels are considered safe by the American Dental Association (ADA) and are less likely to cause tooth sensitivity.14,15,16

Snow’s active ingredients (hydrogen and carbamide peroxide) won’t change the structure of your teeth. However, they can irritate your teeth’s nerves and increase your risk for sensitivity if you have naturally sensitive teeth.17

Snow Lifestyle 2

Keep in mind that everyone is unique. While Snow develops products for sensitive teeth, you may react differently to its formula.

To prevent tooth sensitivity:  Whiten your teeth once a day and don’t go over 30 minutes for each treatment. If your teeth become sensitive, space every treatment every 1 to 3 days and limit each session to 10 minutes.9

What Customers Say About Snow Teeth Whitening

The Snow Teeth Whitening System is highly rated on Trustpilot, where it received 4.5⭐ from over 3,800+ customers who have tried it.

Positive Customer Reviews

I am at the end of week two. Now I can say that I do see a difference in my teeth. I have been using the little tooth whitener chart number, and I started here around five or six. I would say that I’ve gone down a number. So now I would say I’m hovering around a four or five.

YouTube Review

The first couple of weeks I was thinking, nothing’s going to happen. I’ve tried these things before. It’s going to be like every other product. I will say the last couple of weeks, I have noticed a difference in my teeth.

YouTube Review

Most customers are satisfied with Snow as it gives them a noticeably brighter smile in a short time. Based on reports, they’re gentle on the teeth and rarely cause sensitivity. Many people also find it easy to use.

If you need help with your orders or want to claim your warranty, Snow has excellent customer service if you reach out to them via Instagram or live chat.

Negative Customer Reviews

It kind of works but it’s not magic. You will not go from yellow to white if that’s your case.

Comment on YouTube Review

One thing I didn’t like about this product is that it created a lot of saliva for my liking. But as the days went on, it became easier to manage.

YouTube Review

Some users didn’t get their orders or waited longer for them to arrive. Its support team also takes longer to respond if you contact them via email.
