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.

best teeth straightening 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

Some clear aligner companies use 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 two 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 assess 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.

reviews on best teeth aligners uk
At home teeth aligners don't always 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 two – four weeks. Some brands use a mixture of face-to-face appointments and remote monitoring via an app. You should get new aligners roughly every two 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, also referred to as mail-order aligners or direct-to-consumer (DTC) aligners, are monitored remotely, and it's possible that you won't ever have an in-person meeting with your dentist. While they can effectively realign straightforward cases, they lack the personalised attention of regular dental visits.

Your initial appointment may involve an in-person 3D scan, or you might just be provided with an impression kit to use at home and return by mail. Afterwards, you'll receive all the aligners by mail along with a treatment plan outlining when to switch to the next set.

Some brands offer a night time-only aligner option, requiring about 10 hours of daily wear. This allows for normal daytime activities, with the aligners worn mainly during sleep. However, due to the reduced daily wear time, treatment time is usually doubled.

Many people ask, do at-home invisible aligners really work?

They can be successful for individuals with mild to moderate orthodontic issues and may be a viable option for those unable to afford traditional in-office treatment or who have dental anxiety.

Nonetheless, we always recommend having a chat with a dentist beforehand is strongly advised to determine suitability. Your dentist should also assess and address any existing dental conditions such as cavities or gum disease before starting aligner treatment.


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.
