best teeth aligners

Best clear aligners in 2021? Find out in this brutally honest review!


Let’s be honest, who wants to have ugly metal braces in their mouth? Nobody!

The good news is there is a new technology that allows you to straighten your teeth with invisible braces or clear teeth aligners.

In this best clear aligners review, we will review each one of the aligner companies on the market right now.




4 Top Clear Teeth Aligners (2021 Update)


Yes, we know…THERE ARE TOO MANY TREATMENT OPTIONS! This is why we created this review of each one of these aligner companies for you, in order to make your choice much easier.

Even though these invisible braces/ teeth aligners companies are MUCH cheaper than Invisalign (even though they pretty much use the same technology), of course, you want to make sure the end result will be perfect!

This is why we literally tested each one of them to know which one is the best option! What we found out is they pretty much all use the same technology.

There is not much difference in the length of the process and the quality of the process between companies. The main difference comes down to the PRICE & customer service! 

It is normal to ask yourself “Are these the same as going to the dentist or orthodontist every month?” or Smile direct club is the most expensive, there must be a reason?”.

Everybody does it. But in the end, this new technology WORKS because we tested it. Also, there are plenty of reviews from people who used these invisible aligners and they work.

It is similar to when Uber started a few years ago. Everybody thought it was weird. “It must be crap” people thought.

But in the end, more and more people are using Uber because the service is simply more satisfying. Same thing with Air BnB!



As we have said earlier, we tested each one of these companies and in the end, they pretty much ALL use the same technology.

There was absolutely no difference in terms of speed of orthodontic treatment time, etc.

The only difference was when it comes to price and excellent customer service.

AlignerCo has by FAR the best customer service and they also happen to be the cheapest price on the market right now! You can literally chat with them and they are super fast to answer.

Their at-home-teeth-straightening aligners are also about $400 cheaper when you take into consideration that they give you free retainers (other companies usually charge $100)

#1 AlignerCo



AlignerCo is the cheapest clear aligners on the market BY FAR and they have TERRIFIC customer service…Do we really need to say more? Click HERE TO GET THEM

We basically tried ALL the companies out there and AlignerCo has BY FAR the best customer service and the best price so we put them at #1.

They are a newer company that sells for MUCH cheaper and offers a much better customer service experience than the other companies out there.

At this price, you literally have nothing to lose. They also offer a free retainer, which some companies charge up to $200!


#2 Straight My Teeth


In our opinion, Straight My Teeth is the best option if you live in EUROPE!


They have amazing customer service!

With these at-home clear aligners, customer assistance is the most important thing.

There are tons of horror stories out there from other companies with people not receiving the at-home-teeth-straightening aligners, with problems with the refunds, etc.


They are SUPER cheap.

They are basically the equivalent of AlignerCo when it comes to price. When you convert the currency from Euros to USD, it is basically the same.

As we said earlier, with these at-home teeth-straightening aligners, the two most important things are customer co-operation and the price.


Full money-back guarantee.

You literally have no risk with Straight My Teeth. They offer a full money-back guarantee so if you are not 100% satisfied, you will get your money back.


Free retainers.

Some other companies are charging up to $200 dollars for the retainers you have to wear at the end of your treatment plan, but not with straight My Teeth.



#3 NewSmile


newsmile aligner

In our opinion, NewSmile is the best option on the market right now by far. Here are seven reasons why:


They have great customer service!

Other than the much lower price, the other area where NewSmile really differentiated themselves is with their customer co-operation.

First of all, you can chat with them! And they answer right away so this is a huge plus. You never have to wait for days to get an answer.

At some point, we went on their website and the chat was unavailable for some reason. We sent them an e-mail and within 1 hour we got an answer!


They have thin and transparent aligners.

NewSmile and Candid co have the most transparent aligners on the market as of right now…

But to be honest the difference is REALLY small and you would not even notice. THEY ALL HAVE super transparent aligners. Nobody will even notice your retainers unless you tell them.


Full money-back guarantee.

You literally have no risk with NewSmile. With all the other companies, if you send them back the impression kit and they come to the conclusion that you are not a good fit, they will refund all your money…

But NewSmile takes it a step further and will even refund you if you are approved but simply do not like the projected results you will receive. With them, you literally have zero risks.


Free retainers.

Some other companies are charging money for the retainer you need to wear at the end of the treatment plan. They usually charge around $100. NewSmile charges $0.


It comes with a premium teeth whitening kit & an aligner case.


They were the fastest to send us the impression kit and the aligners.


#4 Candid co.



We also had a somewhat good experience with Candid co. We thought the treatment process was a little bit slower than the other ones but overall everything went well.

Our main problem with Candid co is the price. They are selling their clear aligners at pretty much the same price as Smile Direct Club,

However, they don’t have the same brand trust as them. There is nothing really that differentiates them from the other company.

This is why we ranked them #4. Again, we tried all these companies and they are pretty much all using the same technology so the only thing remaining that you should care about is the price and the customer service.

Candid co is not doing a better job than the other one for these things so we ranked them #4. We are NOT saying you won’t be happy with the results if you go with them.

You will definitely be happy, but what we are saying is you might as well go with a cheaper option like NewSmile who offers the exact same thing at a much cheaper price!


And the winner is…?


As we have explained above, all these companies are using the same technology. The only difference comes down to the price and the customer service.

Candid co DO HAVE the clearest aligners when you look at them and compare them OUTSIDE your mouth to the other aligners…But once you are wearing them, the differences it not even noticeable.

The only reason companies like Smile Direct Club are charging more money than for example NewSmile is because they did a lot of marketing to become well known.

They spent millions of dollars in marketing so THEY HAVE to charge more than the other companies in order to still be profitable.

Also, because they have brand awareness they can get away with charging more!


What are clear Teeth Aligners? Also called invisible aligners?


What exactly are invisible aligners? They are a newer technology that entered the market a few years ago that completely revolutionized everything.

A decade ago if you wanted to straighten your white teeth you had to get these ugly metal traditional braces…Who wants that?

These new companies offer almost invisible teeth aligners which means almost nobody will notice you are wearing them.

This is an absolute game-changer and this is why these invisible teeth aligners companies are becoming more popular than ever.

They basically consist of a tightly plastic tray that sits directly over the teeth. Each set will help realign your teeth gradually and you will change your set every two weeks or so, depending on the company you go with.

A lot of people confuse clear aligners & clear BRACES. Clear braces are usually made of ceramic material ATTACHED to your teeth.

This is one of the reasons why people love clear aligners; you can actually remove them.

It has some kind of psychological effect on people to know they can remove them even though they are supposed to wear them 22 hours per day. They are popularly known as invisible braces.


How Do Teeth Aligners Work?


First of all, the whole process usually lasts between 3 to 12 months. In the end, it really depends on your specific situation.

You will get a series of aligners every couple of weeks that will gradually shift your teeth. It WILL be painful, especially every time you put your new set of aligners on.

This is normal, it means your teeth are moving.

You are expected to wear your aligners a minimum of 22 hours per day, which means you can only remove them when you eat and when you brush your teeth!

The thing people usually love the most about invisible aligners (other than they are much cheaper) is that you don’t need to go visit your dentist (or orthodontist) every month or so.

A few members of our team did the treatment with Invisalign and according to them, these office visits were pretty much pointless.

It consisted of the dentist looking at the teeth for 5 minutes, then setting another appointment next month…A total waste of time

Who is a candidate for clear braces?


You might be a good candidate if you have one of these issues:

  • Mild to moderately crooked teeth (in some rare cases your case might be too extreme and they will reject you).
  • Teeth gaps.
  • Overbites, open bites, crossbites & underbites.
  • Crowded teeth.
  • Overjets (middle teeth overlapping).

The best way to know for sure is to simply go on their website and order an impression kit.

Once you do the impression of your teeth and return it to them, they will send you EXACTLY what your teeth will look like in the end so you have nothing to lose.

Especially, if you go with NewSmile or AlignerCo because the home impression kit is included for free in their offer!




Unless you have a really severe case, we HIGHLY recommend you to go with these clear aligners companies. Don’t be afraid of new technology…

It works exactly the same as traditional braces and in some cases, it works much faster.

If you don’t mind spending $5000+ and you want to go see the dentist every month to track your progress, then obviously Invisalign is the best option for you!

If you don’t mind not having to go to the dentist every month (in our case we were happy about it) and you want the treatment to be as cheap as possible, then we would highly recommend you to go with NewSmile as they are the cheapest and with the best customer service on the market.

Smile Direct Club is also a really good option if you don’t mind paying a little bit more money but you want to go with the most trusted brand.



1. What are the clear aligner benefits compared to metal braces?

Braces use a pull force to gradually move your teeth into their proper positions, while aligners use a push force for you to rotate your teeth. The clear aligners make a very gentle, smooth teeth rotation. Clear aligners are prefered by adults to metal braces that often cause gum bleeding and pain.

Moreover, clear aligners help you with your confidence when you smile because they’re virtually invisible.

2. I am currently wearing braces. Can I make the switch to a clear aligner treatment?

It’s possible! A significant number of patients are being treated with a combination of clear aligners and braces. Talk to your doctor about the best way to treat your teeth.

3. Can I take my aligners off whenever I need to?

Yes. You can take your clear aligners off for eating, drinking and flossing. But to get the best results, wear them for 20-22 hours per day.

4. Are there any restrictions on what I can eat while in treatment?

None! clear aligners are removable so there are no food restrictions at all.

5. Is clear aligner treatment painful?

Temporary discomfort is reported by clear aligner users. But it’s normal, it’s a sign your clear aligners are working.

6. Will smoking stain my aligners?

Yes. We recommend you NOT to wear clear aligners while smoking.

7. Can I chew gum while wearing aligners?

No. Gum will stick to your clear aligners

8. Are aligners suitable for everyone?

Not really. Brands will have a close look at your teeth impressions to find out if you’re qualified for their treatments. Many of them will refund you for the cost of the impression kit if you’re not a candidate.

9. Can I use aligners while I’m pregnant?

It’s not unsafe. But, we recommend you to wait until you’re not pregnant to try clear aligners

10. Are aligners available as an NHS treatment?

Clear aligners are a luxury treatment and not one that the NHS offers.
