Discover 2021’s Best At-Home Whitening Kits Clinically Tested To Safely Brighten Your Smile Faster.

Getting whiter teeth is a goal humans have pursued for thousands of years.

And it’s easy to understand why.

A bright and beautiful smile can grab almost anyone’s attention INSTANTLY.

It can attract that special someone you’ve had your eye on. Or land your dream job.

For ancient Egyptians, white teeth were a sign of beauty and privilege.

They went so far as to apply a whitening paste to their teeth that contained ground pumice stone mixed in wine vinegar.

The ancient Romans actually went a step further…

By gargling their own urine. Yes, you read that right. They believed the ammonia in their pee would help bleach their teeth.

Well, we’ve come a long way since then.

However, despite modern and healthier advancements, it remains a struggle to find teeth whiteners that provide effective and consistent results.

This leads many people to approach the ultimate authority on teeth whitening: their trusted family dentist.

Laser whitening is a procedure offered by many dental practices.

But it can run upwards of $2000 a visit! And the results can fade in as little as 90 days.

Instead, consumers who don’t want to stretch their wallets that wide have turned to over-the-counter teeth whitening products.

Whitening strips have been the preferred method for tens of millions of Americans for the past 20+ years.

One BIG problem with strips is that they often contain hydrogen peroxide.

It’s the same stuff used to kill mold and clear algae from ponds.

Even the smallest amount of hydrogen peroxide can lead to severe discomfort for people who already suffer from sensitive teeth.

And folks who don’t normally feel sensitivity of any kind might experience gum irritation — the second most common side effect of whitening strips.

Whitening strips can also be extremely messy and frustrating to apply.

Other options include whitening toothpastes and gum. While neither are known to cause pain, they won’t get your teeth the desired shade of white you’d hope for.

Which brings us to at-home teeth whitening kits

In recent years, whitening kits have gained significant traction among people who want whiter teeth faster.

Amazon is awash with different brands, which makes it a challenge to find the one that gets you that head-turning smile everyone notices.

The fact is, most fall short in terms of safety, durability and effectiveness.


There are a few high-quality at-home whitening kits designed exclusively to get your teeth noticeably whiter in just a matter of days.

They are also clinically tested to whiten your teeth without ANY pain.

In addition, these dentist-approved products are super convenient to use and will last you for years — including your life’s most important events.

Keep reading to learn more about this year’s best at-home whitening kits.


Why At-Home Whitening Kits?

You’ve probably read about some success stories when it comes to whitening kits

There’s a good chance you’ve also read or heard about other overpriced products that underdeliver what they promise.

So, why choose an at-home whitening kit?

For starters, certain products incorporate blue + red light therapy, an advanced method for preventing tooth stains and whitening teeth.

And they’re clinically tested to brighten your smile faster.

How fast, you ask?

At least 3 shades whiter in only 7 days.

There’s something else to consider…

Especially if you suffer from sensitive teeth and gums.

Some brands have harmful chemicals in their whitening gel, like hydrogen peroxide.

This can lead to great discomfort — even if you don’t suffer from tooth or gum sensitivity!

That’s why it’s important to select a whitening kit with serum containing ingredients that will whiten your teeth with zero pain.

The right whitening kit will use carbamide peroxide, which is FDA (Food & Drug Administration) approved and is very safe if you experience sensitivity of any kind.

Last, but certainly not least, a high-quality whitening kit is going to be super convenient and easy to use right out of the box.

Not only will it be wireless and rechargeable, but the whole whitening process will take about 15 minutes a day.

Think about it…

You can read a book, cook or exercise while you get a smile that will light up any room you walk into.

With so many options online how do you choose the right whitening kit?

How To Find A High-Quality Whitening Kit

There are four key components to consider when shopping for the right whitening kit.

Teeth That Are Shades Whiter In Days – You’d be surprised at how many whitening kits fall short in this department. That’s why buying one that has been clinically tested to consistently help you achieve a smile that is visibly whiter in days should be your priority. Look for a product that features blue + red light therapy. Blue light therapy whitens teeth; red light therapy protects against oral health issues and bad breath. Using both modes at the same time will whiten teeth twice as fast.

Very Safe For Sensitive Teeth And Gums – The slightest trace of harmful chemicals in a whitening kit’s serum can cause severe discomfort for someone suffering from tooth and gum sensitivity. Since hydrogen peroxide is a big no-no, look for a product that has carbamide peroxide, which is very safe to use. You’ll also want a thermoforming moldable mouthpiece that offers superior comfort, especially if you have dental work, like bridges, crowns, implants, fillings and braces.

Convenience – Just because a top brand is “smartly designed” doesn’t mean it’s easy to use. A top whitening kit will be ready to go, with instructions that are easy to follow, right out of the box. In today’s fast-paced world, convenience needs to be as simple as 1-2-3. Consider products that can be recharged quickly, are wireless and get your teeth whiter in about 15 minutes a day.

Durability – It’s no secret that a number of whitening kits break down after a short period of time. Not only do you want one that is tested and approved by dentists for quality and effectiveness, it should also be built to last for years. Keep an eye out for products that are backed by a long-term warranty. It may seem impossible, but there are companies that offer a warranty on their whitening kit for up to a decade!


Top 3 Whitening Kits




#1 The Perfect Smile Whitening Kit From CRI Naturals

Perfect Smile Whitening Kit

The Perfect Smile Whitening Kit

The Perfect Smile Whitening Kit is the most outstanding product of its kind, clinically tested and dentist approved to deliver real results, starting with teeth that are at least 3 shades whiter and brighter in only 7 days. Designed exclusively for people who suffer from sensitive teeth and gums, this advanced whitening process is very safe and will not cause you any pain. Perfect Smile features blue + red light therapy, ensuring that stains are prevented, oral health is protected and teeth are whitened faster — in just 16 minutes a day.

A Product That Stands Apart For Professionally Whitening Teeth Faster And Helping You Achieve A Beautiful Smile That Everyone Will Notice.

The Perfect Smile Whitening Kit is in a class all by itself. Full stop.

A state-of-the-art, but easy-to-use product, this whitening kit has been clinically tested and dentist approved to get your teeth at least 3 shades whiter in only 7 days. These fast and effective results are due to its advanced blue + red light therapy.

And the last thing you’ll have to worry about is suffering sensitivity in any area of your mouth. That’s because carbamide peroxide is among the chemical-free ingredients in Perfect Smile’s whitening gel, which helps prevent some of the toughest stains, like those from red wine and coffee.

The thermoforming mouthpiece is soft, comfortable and easy to bite down and hold in place. For people who experience sensitive teeth and gums, this mouthpiece will not cause any discomfort.

You won’t be needing wall sockets or cell phones for the Perfect Smile Whitening Kit, since it is wireless, allowing you to move around freely during the whitening process. The mouthpiece comes with a sleek charger that plugs into any USB port, and a fully charged unit can be used for up to 4 hours.

In addition, this is a well-designed and durable device that will last you for years. In fact, CRI Naturals stands behind it with an incredible 10-Year Warranty. And, if for any reason, you’re not completely satisfied with the product, you can return it within 90 days for a fast and full refund.

CRI Naturals’ customer service staff are among the best in the business: highly knowledgeable, courteous and helpful.

#2 Snow

Launched in January, Snow’s latest roll-out is the 2nd Generation Wireless Teeth Whitening Kit. The company bills this advanced unit as its “best at-home kit ever.” It is, in fact, easier to use than the previous model, in addition to being more powerful.

The product features their unique whitening serum with an LED mouthpiece to whiten teeth faster. Cold light technology brightens teeth, while supporting gum health during the whitening process.

Snow is self-sanitizing: an automatic UV light cleans the mouthpiece while it’s stored inside the charging case. It’s also water-resistant, travel friendly, manufactured in California and comes with free shipping and a 5-Year Limited Warranty.

While we find Snow’s 2nd Generation Wireless Teeth Whitening Kit a solid product, our main issues are affordability and durability. Selling for nearly $300, the device is one of the most expensive of its kind on the market. In terms of durability, after several months of consistent usage, we found that several kits stopped working after 4-5 daily whitening sessions.

It also took several attempts to finally get a hold of someone in customer support, which we found frustrating. And while their 45-Day Money Back Guarantee and 5-Year Limited Warranty demonstrate that they stand behind their product, they are not anywhere near industry-leading.

  • Easier To Use And More Power Than Previous Snow Models
  • Cold Light Technology Brightens Teeth And Supports Gum Health
  • Made In The USA

  • More Expensive Than Other Proven Wireless Whitening Kits
  • Durability

#3 Glo

Glo is a well-designed whitening kit that features an advanced warming heat acceleration technology. Designed and patented by a top aesthetic dentist, the mouthpiece incorporates a sensitivity-free hydrogen peroxide gel in its treatment.

The product is registered with the FDA, though the company provides only a 1-Year Limited Warranty on the product. Glo comes with a special app that connects to the device through Bluetooth, allowing you to track your results and receive reminder notifications when it’s time to whiten your teeth.

In addition to being one of the more expensive whitening kits on the market, we also found the device a bit cumbersome. The mouthpiece plugs into a power pack, which you wear around your neck, essentially “wiring you up” more than some other quality wireless products currently available.

  • Features an Advanced Warming Heat Acceleration Technology
  • Approved by the FDA

  • Company Only Provides a 1-Year Warranty
  • More Expensive Than Other Proven Whitening Kits


Of the top-three whitening kits we selected, Perfect Smile is our clear-cut winner.

Obviously, what sold us extremely quickly is the fact that this product gets teeth shades whiter in only 7 days. And that its whitening process is very safe and pain free.

Convenient and easy to use, not to mention highly reliable, the user is left not only with a bolder, more beautiful smile, but peace of mind that it will last for years and years, thanks to this remarkable device.

The Perfect Smile Whitening Kit is also more affordable than much of its competition, and a fraction of the cost of multiple laser whitening sessions at a dentist’s office.

The company behind the Perfect Smile Whitening Kit, CRI Naturals, deserves much credit for creating another superior oral care product, following in the footsteps of its predecessors: the Perfect Smile Electric Toothbrush, Perfect Smile Water Flosser and Perfect Smile Whitening Brush.

The whitening kit comes with an incredible 90-Day Money Back Guarantee and a 10-Year Product Warranty. So, if it shows even a hint of wear and tear, you can easily contact the CRI Naturals customer support team and they’ll replace your whitening kit free of charge.

My team and I feel extra good about recommending the Perfect Smile Whitening Kit because it is eco-friendly. We love the fact that we’re not adding more whitening strips, toothpaste tubes and gum packets to our landfills.The fact that it is wireless saves energy and cuts down on more batteries being thrown in the trash. Whenever you can do something that makes life easier, makes you healthier and helps the planet…why wouldn’t you do it?
