Best Teeth Whitening Kit 2020 – The Ultimate Buying Guide

Let’s do a quick little exercise before we start this article. Close your eyes for a second if you will and imagine yourself meeting a stranger for the first time.

It doesn’t matter who it is, but within the first few seconds, what are the very first things you notice?

Most people will probably say one of two things – their eyes or their teeth. Both of these things have the chance to really change somebody’s first impression about you.

If you don’t like your eye color, unfortunately there’s not a whole lot you can do to permanently change that.

However, if you don’t like the way your teeth look, then there are tons of options out there for you to change that! While straightening your teeth might turn out to be complicated and expensive, you can whiten your teeth for relatively cheap!

Arguably, whitening your teeth might be important than getting them straightened.

If you have a beautiful bright shining smile, people are sure to notice within the first few seconds.

Think about it:

How many times have you noticed someone’s really white teeth and complimented them on it?

Having whiter, brighter teeth will not only change people’s first impressions of you but it also has the ability to give yourself more confidence!

So how do you get whiter teeth?

You need to buy the best teeth whitening kit out there! And lucky for you, we’ve compiled a list of the best ones out there.

Take a look!

Top 14 Teeth Whitening Kits For 2020

Check out our complete list and what each kit’s method is before getting into each of the reviews for the best teeth whitening kit.

Cool! Now take a look at each of the reviews.

Shine Whitening Teeth Whitening Kit – Works Fast!

There are a few different ways you can whiten your teeth, and we’ll get into each of them as we go along. One of the most popular ways is using a combination of gel and an LED light.

First you have to mold the included mouth guard to your mouth, which usually takes under a minute. Once it’s molded, go ahead and take it off.

After that, you need to apply the gel to your teeth using the included syringe and a Q-tip. Once you have a nice even layer, then put the mouth guard back on to make sure it doesn’t get on your inner lips.

Don’t forget!

Try to avoid your gums! The gel is safe for your mouth but if might burn a little bit if you get too much on them so just make sure you’re careful when applying the gel.

One last thing to note

The company recommends putting the gel into the mouth guard first and then putting it on your teeth. We found this to be a bit wasteful.

We definitely recommend putting it on your teeth first so you only use exactly what you need. You’ll get many more uses out of it this way.

This is a decent whitening kit and is good for most teeth. We don’t necessarily recommend it if you have overly-sensitive teeth, however.

What We Loved

  • Works quickly
  • Get a lot of uses

What We Didn’t Like

  • Not great for sensitive teeth

Active Wow Teeth Whitening – Trusted Name Brand

If you’ve done any research whatsoever into teeth whitening, you’ve probably come across the brand name Active Wow. They’re super trusted when it comes to teeth whitening.

Not only do they offer kits like this one (gel/light) but they also offer charcoal whitening and a couple of other methods, which we’ll get into later.

This is a premium grade kit and all ingredients are made in the USA, which is a nice bonus.

We like this kit a little better than the last just because it’s from a trusted name and doesn’t burn quite as much as the last one.

Let’s do a quick recap on what to do:

Apply the clear gel, apply the mouth guard, wait 15 minutes, rinse, apply the blue gel, apply the mouth guard, wait 15 minutes, then rinse.

While you’re waiting the 15 minutes with the mouth guard, make sure you use the LED whitening accelerator!

Why, you ask?

Because it will accelerate the whitening process! If you already have one of the LED lights, you can often times buy just the gel for much cheaper.

One thing to note about this kit is that some people it made their teeth more sensitive for a small period of time. It does go away, but something to be aware of.

What We Loved

  • Trusted name
  • LED light accelerates process

What We Didn’t Like

  • Makes your teeth sensitive for short period of time

AuraGlow Teeth Whitening Kit – Don’t Have To Mold Tray

If tooth sensitivity is something that you’re actually concerned about, then consider going with the AuraGlow kit.

This kit is a bit pricier but it works well on more sensitive teeth in addition to not making them sensitive!

That’s a win-win if you ask us!

One cool part about this kit is that they mouth tray doesn’t require any molding or boiling so it’s good to go straight out of the box.

It will fit any mouth!

You should be able to get around 20 treatments out of this, although you’ll most likely notice results in a much quicker time frame.

While a lot of other gel kits require you to use a clear and blue gel, this only requires you to use the clear gel.

There is one downside to that however:

No break in between! Sometimes it can be uncomfortable sitting with that gel in your mouth and at least you get a break if you have to switch gels and rinse.

The AuraGlow kit also comes with a timer and beeper so you know exactly when it’s time to be done – a nice little added bonus!

We love the AuraGlow kit and definitely think it’s worth the extra money – if you can stand to have the gel on your teeth for 30 minutes straight, that is.

What We Loved

  • Comes with timer built in
  • Don’t have to apply 2 different gels

What We Didn’t Like

  • A bit pricier

Active Wow Teeth Whitening Charcoal Powder – Great Natural Method

We told you before that Active Wow is a popular name in the teeth whitening industry, and we weren’t lying!

This is the first different type of teeth whitening we’re featuring on the list and is something that’s become trendier in recent months.

Activated charcoal whitening.

If you’re looking for more of a natural solution, then charcoal might be the route for you.

This might not be the overnight fix that you were hoping for, but it will definitely work.

You simply brush as you normally would except you use this activated charcoal instead!

The ingredients it features are:

Organic coconut activated charcoal powder (main ingredient), bentonite, and orange seed oil which is also a natural teeth whitener.

We completely understand that some of the dental-grade solutions aren’t for everybody.

To be fair, they can be a little bit scary! You feel that burning sensation and you might panic a little bit.

Although those solutions are perfectly safe, they aren’t for everyone and this activated charcoal powder might just be the solution.

One thing to note – it is a bit difficult to rinse and if you miss any, then you risk walking around with black powder in your teeth all day. So just be careful!

What We Loved

  • All natural ingredients
  • Doesn’t burn whatsoever

What We Didn’t Like

  • Difficult to rinse
  • Takes a few days to see results

Dr. Song Home Professional Teeth Whitening Kit – Extra Strength Product

If there’s one lesson to learn in the beauty industry, it’s that not every name with the word “Dr.” in it means better results.


We think in this case, it does.

This is a really reliable kit that will leave your teeth multiple shades brighter after only four days.

If you have an event coming up or need your teeth to be super white in a very short amount of time, then we highly recommend the Dr. Song Home Professional Teeth Whitening Kit.

They also offer a 100 day 100% no hassle money back guarantee – so you know Dr. Song really stands behind their product.

This is an extra strength product and even comes with an applicator brush! No need to use any extra Q-Tips. Simply use, wash, then re-use the brush that comes with this kit!

This includes a moldable tray but the tray with this one is a bit trickier to get to your liking.

So if you don’t like to fuss around with the whitening trays, then this might not be the kit for you.

Overall though this kit from Dr. Song provides fast, clean, professional-looking results.

We love it and know you will too.

What We Loved

  • Extra strength product
  • Professional clean look

What We Didn’t Like

  • Tricky to mold the tray

Crest 3D White Glamorous White Whitestrips – Tried and True Method

Sometimes you just can’t beat the classics. While we love some of the more advanced techniques, we’ll always be in love with Crest White Strips.

The thing is:

They work brilliantly for some people.

But not so brilliantly for others.

So we say, you should try these first for a couple of different reasons.

First, they’re not as expensive as a lot of the gel and tray methods.

Second, they’re not as harsh on your teeth.

Third, they’re one of the easiest techniques to use!

If  they work for you, why would you bother going through more extreme methods?! We say you should at least give them a shot before moving on to the professional-grade whitening.

All you have to do is place the strips on, leave them on for 30 minutes, then take them off.

Easy as that.

No tray molding.

No brushing on the gel.

No putting on two different types of gel.

Just put the strip on, wait, then take the strip off.

So if you’ve heard bad things about Crest white strips and haven’t bothered, we say you should see for yourself. We love them and they do work pretty well for a majority of people.

What We Loved

  • Don’t have to mold the tray
  • Easy to put on
  • Good brand name

What We Didn’t Like

  • Not as powerful as professional-grade kits

AuraGlow Radiant Effects Teeth Whitening Kit – Good For Sensitive Teeth

Up next is another kit from AuraGlow. This one is the ‘Radiant Effects’ edition so it’s a bit more powerful – but of course a bit more expensive.

This is a great kit, however.

You’ll get professional whitening results with an enamel-safe formula.

It removes plaque and years of stains all while avoiding sensitivity!

And guess what?

It includes four different whitening trays!

Have you already seen results after only three uses?

Perfect! Save the rest of the gel and now you’ll even have trays left over to use for the next time.

We absolutely love that they give you so many whitening trays. Moldable whitening trays.

Another benefit of molding trays over non-molding is that they ensure a more even application as it fits the exact shape of your teeth.


And AuraGlow even includes a case for the tray that you’re currently using.

One downside is that you only get the clear whitening gel with this one – not the blue remineralizing gel.

AuraGlow also doesn’t include the light with this kit, which is kind of a bummer. Although if you’re sold on the kit without the light, you can always purchase it separately.

What We Loved

  • Get a lot of whitening trays
  • Goes on evenly

What We Didn’t Like

  • No LED light

Harmony Life Teeth Whitening Kit – Most Bang For Your Buck

If you’re looking for the most bang for your buck then look no further than the Harmony Life Teeth Whitening Kit.

How much exactly do you get?

And for what price?

Well, we can tell you that at the time of this article, the kit cost under $20…

For 50 applications!

That’s right – you read that correctly.

50 applications! That’s an insane amount for such a low price. They also include a bunch of different trays just in case you mess up molding them, or for other members of  your family.

You also don’t need to use this for as long as some of the other kits. In fact, it’s recommended that you only leave it on for 5 to 15 minutes.

If you want stronger results then you can leave them in for up to 20 minutes.

This is a decent kit overall.

The one downside?

This is not suited for those with sensitive teeth. It’s a pretty intense gel so if you have any tooth sensitivity whatsoever – you should probably go with another brand.

What We Loved

  • Comes with a lot of applications
  • Good price

What We Didn’t Like

  • Not great for sensitive teeth

Stardust LED Teeth Whitening Kit – Great Desensitizing Formula

Coming up next down the pipeline is a kit from Stardust.

This kit stands out above the rest for a few reasons.

First – the formula for the gel was developed by a cosmetic dentist.

Second – their blend of the gel is proprietary and includes a gel that’s desensitizing.

Essentially, it doesn’t allow your teeth to feel pain so you shouldn’t feel any sort of discomfort or at least reduced discomfort while using this gel.

Another thing we love about this kit?

You don’t have to use it for 30 minutes at a time.

We can all admit that teeth whitening isn’t the most enjoyable task in the world so the less time you get to spend doing it, the better.

One thing we don’t love about this Stardust kit?

It only includes two trays. That means you only have two chances to get it right when you’re molding it to your teeth.

This isn’t the end of the world and as long as you’re careful, you should be fine.

We love the fact that this was developed by an actual cosmetic dentist.

We also love that you only have to keep it on for 5-15 minutes. It might just be the best teeth whitening kit with light.

We don’t love that it only comes with two trays but if you love the formula, you can always buy more trays!

What We Loved

  • Has a desensitizing formula
  • Only have to use for 5-15 minutes

What We Didn’t Like

  • Only comes with two whitening trays

Crest 3D White Professional Effects Whitestrips – More Advanced Whitestrips

We had to include another option from Crest Whitestrips.


Crest actually has a wide range of options for white strips that you can choose from depending on exactly what you need.

These ones are the professional effects and they work amazingly!

It includes 40 strips or 20 treatments – one strip for each the top and the bottom every time you apply the strips.

These seriously will remove years and years of stains in just a few uses.

We also love this set because it comes with a bonus!

Who doesn’t love free stuff?

Included with the regular set of 20 treatments, is two extra express whitening treatments.

If you have an unexpected event coming up or just need to do a refresh, you just pop on these for an hour and your teeth will be noticeably whiter.

They include two of the express treatments! This isn’t bad for a kit that costs under $50.

One tricky thing about the strips is that you have to apply them yourself, and is often the main complaint about Crest white strips.

This can leave room for error as you might not apply it perfectly evenly.

However, we say if you’re careful, you’ll fall in love with these Crest 3D White Professional Effects Whitestrips just like we did.

What We Loved

  • Includes two express treatments
  • Decent price

What We Didn’t Like

  • A little tricky to get it even

Smartsmile Professional Teeth Whitening Kit – Don’t Need to Leave On For Long

Up next we have a tooth whitening kit from Smartsmile!

We’ve been loving the gel kits on the second half of this list for one simple reason.

You don’t have to leave them on for as long!

It can really make a big difference as to whether or not you stick with this routine or not. A lot of people give up because they can’t find the time to do it consistently.

However, if you only need to do it for 5, 10, or 15 minutes then it’s easy to always find the time!

A lot of teeth whitening gels have a weird taste – especially a weird after taste.

Not with the SmartSmile Professional Teeth Whitening Kit.

It actually has a fairly pleasant spearmint taste that makes it enjoyable to use!

Well, as enjoyable as a tooth whitening kit could possibly be.

This gel contains 35% carbamide peroxide, which is the active ingredient in most teeth whitening kits and 35% is about industry standard.

Why not go way higher?

Because then your teeth and gums would burn and burn and burn!

All in all, this is a decent kit from Smartsmile. It doesn’t include a LED light, but that saves you some money and those aren’t 100% necessary anyway.

What We Loved

  • Don’t have to leave them on for long
  • Professional results

What We Didn’t Like

  • Doesn’t include LED lights

iWhite Teeth Whitening Strips Teeth Bleaching System – Good Alternative to Crest

You know….

There are other companies out there besides Crest that makes whitening strips.

iWhite is one of those companies – and we have to admit…

They give Crest a run for their money.

They provide you with a 14-day’s supply of strips, which should be more than enough for you to start seeing results.

In fact, depending on how bad your teeth are, you could potentially split this into two separate treatments of one week each!

They’re that powerful.

One thing we like about the iWhite strips over the Crest white strips is that they’re much easier to apply.

They also stay in place much better than the strips from Crest.

iWhite even provides you with a little shade scale so you can see exactly how much whiter your teeth got!

If you love the strip format but have just been looking for an alternative to Crest, then we recommend that you give iWhite a try.

They’re fast.

They’re efficient.

They’re easy to put on.

And they’re great even if you have sensitive teeth.

Give these strips from iWhite a shot!

What We Loved

  • Easy to put on
  • Good if you have sensitive teeth

What We Didn’t Like

  • Doesn’t work as fast without LED light

Zero Glow Teeth Whitening Kit – Premium Whitening Kit

Alright, back to the most popular method of teeth whitening:


This is a premium whitening kit from Zero Glow but fortunately, it’s not at a premium price.

This features our favorite format of the gel/light combo – a whitening gel for 15 minutes, rinse, then a blue remineralizing gel for another 15 minutes.

Aside from the fact that the blue gel strengthens your teeth, we just like the break that you get between gels!

These also work very quickly.

Have a last-minute event coming up you forgot about?

Definitely try this kit from Zero Glow.

One thing we do want to note is that the whitening mold is a bit thick.

Why is this bad?

It makes it that much more difficult to really mold it to the exact shape of your teeth.

While this definitely isn’t a make or break issue, it’s definitely important to point out. If you usually struggle with that part of the process and want the gel that this kit comes with, consider getting the mouth guard independently.

What We Loved

  • Whiten your teeth quickly
  • Get professional results

What We Didn’t Like

  • Difficult to mold

All Natural Teeth Whitening Powder – Another Great Organic Solution

As we near the end of our list, we had to sneak in one more charcoal teeth whitening powder.

We’ve already gone on about all the benefits so we won’t bore you again.

But just as a reminder:

We love the activated charcoal whitening powder!

This is a great little powder from a trusted brand, FineVine.

This powder from FineVine features super high-quality ingredients and doesn’t feel gritty in your mouth whatsoever.

While it is made from high-quality ingredients, there’s still a downside.

It tastes disgusting. Yuck.

It’s actually probably one of the worst tasting charcoal powders we’ve come across.

Oh well, you can’t win them all. This isn’t a cooking competition, after all.

And it does what it says – it whitens your teeth.

What We Loved

  • Features high-quality ingredients
  • No chemicals

What We Didn’t Like

  • Tastes bad

How To Pick The Right Teeth Whitening Kit

It may seem a bit overwhelming purchasing your very first teeth whitening kit. We understand.

There are so many different options!

Each one says it works the fastest and the best but they can’t all work the best!

It just doesn’t make any sense.

If you want to buy the best teeth whitening kit, then you’re going to need the best one that works for you.

Check out our guide to make sure you’re considering all the correct factors before you buy your kit.


This is going to be the first thing you want to decide on. Do you want a gel/light combo? Or perhaps you’re really attached to the idea of using strips? Or maybe you don’t want to use chemicals at all and want something completely natural such as a charcoal powder.

Whatever you decide, each has their pros and cons and will depend on how quickly you need your teeth whitened.


Do you have sensitive teeth? If so – be careful. A lot of the professional grade kits can really hurt your teeth while the gel is in.

If you have extra sensitive teeth, we recommend going the more natural route. Or at least read the reviews to make sure the gel has a desensitizer!


The last important factor you want to consider is how fast does this work. If you’re wondering how to whiten your teeth in one day, you might consider the gel/light method.

Organic methods, such as the charcoal powder tend to take longer to see results. You’ll often get similar results over time, but not within 24 hours.


At the end of the day, exactly which kit you choose will depend on exactly what you need.

In fact, they’ll most likely depend on the factors from our buyer’s guide.

But there’s still one whitening product that we feel will work best for everybody and in most situations.


The Active Wow Activated Charcoal Powder jumped off the page for us.

We love the charcoal powder because there are no chemicals, it doesn’t burn, you can use it daily, and it works just as well as the kits! We really believe it’s the best teeth whitening method.

It just takes time. Active Wow is also an extremely trusted brand when it comes to teeth whitening so we really trust their products.

We really hope this helped with your decision and you’ve found the best teeth whitening kit! We tried to be as comprehensive as possible and include a variety of products that will work for everyone.

Thanks for reading and cheers to a brighter smile!
