If you are looking for the best teeth aligners in the UK, you've come to the right place. Not everyone who has crooked or misaligned teeth wants to wear braces, and clear aligners are a popular and much less noticeable option.

We reviewed 6 different products and found Smile White and NewSmile to be the best teeth aligners available in the UK.

In this article, we'll be discussing the following points about each type of aligner to help you decide which one is the best choice for you:

  • Teeth aligner price range
  • In-office or remote supervision
  • Aligner treatment time
  • Who is eligible for clear aligners?

Let's get started and explore some of the best at-home teeth straightening treatments in the UK to find the perfect fit for you.

Invisalign too expensive? Here's what we recommend…

Our top pick is Smile White Aligners. They provide the quality treatment only in-person monitoring can provide, but they're up to 40% cheaper than Invisalign. And unlike totally remote aligners, Smile White can treat even complex cases of bite misalignment!

As a bonus, you'll also get free retainers and whitening. You can book a free e-consultation to see whether they are a good option for you.

Our top recommendation for 100% remote treatment, NewSmile, is a Canadian brand providing home aligner treatment since 2018. They have recently launched in the UK and offer the best value treatment package. For just £1,295, you get:

best teeth aligners UK
What are the best teeth aligners in the UK?
  • Home impression kit
  • Treatment preview
  • Full aligner treatment
  • First set of retainers
  • Free whitening treatment

If you chose their nighttime treatment, it costs a little extra at £1,395. All treatments have flexible payment options with 0% interest.

You'll get a full refund if NewSmile's network of dentists and orthodontists decide you are not a good fit for the treatment. You also have the option to purchase an impression kit for £39 to get started, without committing to the full treatment.

NewSmile aligners are made from Raintree Essix plastic, which is the clearest plastic for aligners available on the market today. These aligners work on multiple teeth at the same time, which is why they can keep treatment time to just 4-6 months on average.


There's also SmileDirectClub, which costs £2,050, with daytime or nighttime treatment available.

One benefit of SmileDirectClub over other home aligner brands is its network of SmileShops in the UK. These are physical locations that you can visit for a free 3D mouth scan – an option if you want to get started quickly or don't like having to do putty impressions.

However, if you prefer to do everything from home, or there isn't a convenient SmileShop nearby, you can also order an impression kit.

These aligners are suitable for mild corrections, so if your case is more complex, then you may still need to go down the traditional braces route.

NewSmile is a Canadian company that brought its clear aligners to the UK market in 2022. NewSmile aligners are made from the clearest material and the company offers excellent service at the best price.

They don't have any physical locations, so you'll need to purchase an aligner kit to get started. One of their Impression Specialists will guide you through the process on a video call when you're ready.

NewSmile aligners are very affordable, costing just £1,395 (currently discounted to £1,295). But even better, this price includes whitening foam to use in your aligners, plus your first set of retainers!

Choose their daytime package for treatment in 4-6 months, or nighttime aligners for a more discreet treatment that takes 8-10 months. Both options come with 0% interest payment plans available.


Invisalign aligners from Align Technology are some of the best-known aligners around the world with over 11 million patients treated so far.

Invisalign aligner treatment has
direct orthodontic supervision

Invisalign braces are probably the most similar to fixed braces when it comes to effectiveness because they can treat the majority of orthodontic cases. The average treatment cost is around £4,000 using Invisalign Comprehensive, making it comparable to fixed braces in terms of cost, too.

Treatment with Invisalign Comprehensive takes 12-24 months on average, largely depending on the complexity of your case.

Even if you have milder orthodontic issues, Invisalign treatment is still a great choice because of the direct orthodontic supervision and overall care and service. However, if you are on a tight budget, there are more affordable options that can be just as effective.

I got Invisalign – the first 24 hours

The following video is a review from YouTube vlogger, Emma Louise. This is a great example of someone who didn't have major orthodontic issues but still opted for Invisalign treatment.

She takes us through her consultation with her Invisalign provider, the process of getting her aligners, and learning how to take them in and out of her mouth.

Emma's review is only of the first couple of weeks of having Invisalign aligners. She says that she will continue to do updates on her YouTube as her treatment progresses, but so far she is happy with it!

Clear Correct

ClearCorrect is another well-known in-office aligner company. They were founded in 2006 in the US, and later launched in the UK.

Both Invisalign and ClearCorrect require
checkups with your dentist

They are similar to Invisalign aligners except they are made from a slightly thinner material (Polyurethane resin). According to some reviews, this thinner material is uncomfortable and may cause sores on your tongue. But, other patients find it more comfortable.

ClearCorrect work with a network of dentists to provide treatment, but unfortunately, it isn't always easy to find a provider. This is because they don't have an easy-to-access list of providers in the UK. Your best bet at finding a ClearCorrect provider near you is to ask your local dentists.

Treatment can take between 3 months to 18 months depending on the complexity of your case, with more complex cases taking longer to treat. The cost of these aligners can range between £1,800 for mild cases that last just 3 months, to £4,500 or more.

ClearCorrect before and after – was it worth it?

In the following video, YouTube vlogger Cassie Nero reviews her ClearCorrect experience and shares her before and after pictures. She says she feels a lot more confident with her teeth after treatment, however, she does think that something is not quite right with her jaw.

Cassie does say this is probably from grinding her teeth or using a dummy as a child, but she has only noticed it after treatment so she will get it fixed in the future.

Straight Teeth Direct

Straight Teeth Direct is another at-home aligner option. The treatment process begins with an online assessment, then you must purchase an impression kit for £69 or visit their dentist in London at a cost of £79. After being approved, the treatment itself costs £1,550, including one set of retainers.

Like most at-home aligners, Straight Teeth Direct can only treat mild to moderate orthodontic issues. No nighttime option is available, and the standard treatment takes 5-9 months.

All of your treatment monitoring is done remotely via an app, with an orthodontist checking your progress, and you change your aligners every couple of weeks following your plan.

Dr Smile

teeth clear aligners
PlusDent is a hybrid system of in-office
and remote monitoring

These aligners are relatively new to the clear aligner market in the UK. Treatment is carried out from home, but you do visit a GDC-registered dentist for a consultation before your treatment is approved.

You also have the option of an in-person visit if needed at any time. The rest of your treatment is monitored remotely via an app.

Once your treatment has begun, you are required to check in on the app and switch aligners every 2 weeks. According to reviews, some people don't always manage to check in on the app when they should. This can lead to problems down the line if something goes wrong with your treatment.

There are no fixed prices for Dr Smile aligners; it depends on how your treatment is classified after the initial assessment. However, most cases cost between £1,390 and £2,090 to treat. Payment plans are available so you can choose to pay monthly.

Buying guide for invisible aligners

What are invisible aligners?

Invisible aligners are custom-made, clear plastic trays that apply pressure to straighten your teeth. Aligner treatment is a removable alternative to fixed braces and they are less visible when worn. These clear aligners can generally only treat mild to moderate orthodontic cases.

Some invisible aligner options, like Invisalign, can treat more complex cases using attachments and elastic bands.

How do teeth aligners work?

Teeth aligners work by closely fitting to your teeth and applying pressure. Over time your teeth will gradually move into the desired positions and your smile will be aligned.

Although this is how most clear aligners work, there are a few key differences between brands. The most important difference is that some aligners are at-home treatments, and some are in-office.

In-office aligners

In-office dentist aligners are generally more thoroughly supervised by a dentist or orthodontist. They require an initial appointment at a dental practice to access your eligibility. Then, you will get a 3D scan of your teeth, or impressions made. You will receive a treatment plan that maps your entire orthodontic treatment.

dentist aligners
Not all aligners require dentist visits

Once you receive your aligners, you will be expected to wear them for about 22 hours per day. This may change between brands but wearing aligners for fewer hours per day might cause your treatment to take longer.

Usually, you are required to attend in-practice check-ups every 2 – 4 weeks. Some brands use a mixture of face-to-face appointments and remote monitoring via an app. You should get new aligners roughly every 2 weeks to continue your treatment, all going well.

These types of aligners cost around the same as traditional braces, and you receive the same level of hands-on care with regular visits to your dentist. In-office aligners like the Invisalign system can treat more complex orthodontic cases than at-home aligners.

At-home teeth aligners

At-home clear aligners, otherwise known as mail-order aligners or direct-to-consumer (DTC) aligners, are supervised remotely, and you may never meet your dentist in person. Although they can treat simple cases effectively, you don't get the same hands-on care that you would from visiting a dentist regularly.

Sometimes your first appointment will be in-person for your 3D scan, or you may just receive an impression kit that you will do at home and send back. You will then receive all the aligners in the post along with a treatment plan. This treatment plan should tell you exactly when to change to a new set of aligners.

Certain brands offer a nighttime-only aligner treatment option, which means that you only need to wear your aligners for around 10 hours per day. Because of this, you can go about your day as normal and just pop your aligners in at bedtime. Since you're only wearing your aligners for half as long each day, it will take around twice as long to complete the treatment.

But are at-home invisible aligners really any good?

We can say that they do work in many cases for people with mild to moderate orthodontic issues. They can be a good choice for patients who can't afford in-office treatment, or who are very afraid of visiting the dentist.

However, we would always recommend speaking to a dentist first to understand whether you are a suitable candidate. Your dentist should also check for any cavities, gum disease, or other conditions that should be treated before wearing aligners.


Depending on your orthodontic needs, there are teeth aligners to suit everyone. Our recommendation for the best clear aligners for teeth is Smile White and NewSmile, for convenience at an affordable price starting from 1,295.

Other options out there vary in terms of the level of service, cost, treatment time and accessibility. The best teeth aligners for you will depend on a combination of these factors, as well as the amount of correction your teeth need.
