Best Invisalign Alternatives in the UK? Explore Invisalign Competitors

Contributors:  Amanda Napitu

There are numerous Invisalign alternatives on the market these days. And for good reason. Many people who want to straighten their teeth are looking for options that are less noticeable than traditional metal braces.

Straighter teeth can not only boost your self-confidence but also improve your overall oral health. But with all the different brands out there offering clear aligners, how do you choose between Invisalign and their competitors?

Invisalign aligners are not the only alternative to metal braces

Don't worry, we are here to help. Whether you're looking for a cheaper alternative to Invisalign and braces or a way to straighten your teeth without visiting the dentist every month, you've got plenty of options.

We've created this guide which covers Invisalign competitors and alternatives in the UK, both in-office and at-home, including:

  • ClearCorrect
  • Smile Direct Club
  • NewSmile
  • Straight Teeth Direct
  • Smilelign
  • Wondersmile
  • Straight My Teeth
  • Dr Smile

We hope this guide helps you figure out which alternative to braces is the best option for you! Alternatively, if you want to learn more about Invisalign costs, we have a separate page covering them in more detail.

Remote vs. In-office aligners

We'll assume that by this point in your research, you're quite familiar with how Invisalign treatment works. You go to your local provider, they scan your teeth or take impressions, those get sent to a dental lab, and a few weeks later your first sets of aligners are ready. You go back to your dentist or orthodontist to have them fitted, and return every month or so for checkups and to collect your new aligners. Alongside this, you use Invisalign's app to track your progress.

Now, the Invisalign system is one of the best in this market; they've been operating for over 20 years, have treated over 11 million patients, and their aligners use cutting-edge technology backed by great research. This means that they can treat up to 90% of orthodontic cases, including some quite severe malocclusions.

But, there's a new breed of clear aligner brand which has become popular in the UK recently, and that's at-home aligners or ‘remote orthodontics'. The difference with these is that you don't visit a dentist or orthodontist; instead, you can carry out the entire process from home and your aligners are sent directly to you.

Here's a quick summary of how these options compare:

There's no one-on-one dentist contact with at-home options

There are a few names in this market, which we will go into below, but they all operate in basically the same way:

  • You take an online assessment to check that you're a suitable candidate
  • You either order a home impression kit or visit one of their clinics for a 3D scan
  • Your scans or impressions are sent to their lab, which creates your aligners
  • You receive your aligners in the post
  • You check in online by taking photos of your teeth as your treatment progresses
  • A dentist or orthodontist monitors your treatment remotely

By cutting out the in-office visits, these can market themselves as cheaper alternatives to Invisalign and braces. However, they aren't suitable for everyone. Most can only provide mild to moderate straightening on the front six to eight teeth. Plus, the dental community has naturally raised some concerns over the safety and efficacy of this type of treatment.

So, there are pros and cons to home aligner treatment, but they can be very appealing if you are looking for a cheaper Invisalign alternative. Here are our top picks, if you want to check them out straight away:

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.

We do recommend that you visit a dentist before commencing any type of aligner treatment. They should check that your mouth is free from cavities, gum disease, or any other issues that should be resolved before wearing aligners.

At-home Invisalign alternatives in the UK

Let's look first at some of your options for remote orthodontic treatment from home. Not only are these options generally cheaper than Invisalign treatment; they also have the added convenience of not requiring in-office visits.

Some brands even offer nighttime-only treatment, meaning you only have to wear your aligners for 10 hours a day. This treatment takes around twice as long, but if you really don't like the idea of wearing aligners to work or school, this could be a good choice for you.

Here are some other things to keep in mind as you choose your aligner brand:

  • Do they have clinics you can visit for a 3D scan?
  • How do they monitor treatment?
  • How long does treatment take?
  • How much does it cost?
  • Is whitening treatment included?
  • Do they provide retainers to wear after straightening?

So, let's take a look at some of the UK's best Invisalign alternatives.

Smile Direct Club

Smile Direct Club is one of the bigger names in this business. Although they only launched in the UK in 2019, they have been operating in the US for several years.

The main benefit of Smile Direct Club compared to others in the UK is their network of SmileShops – physical locations you can visit for a free 3D scan instead of having to take your impressions at home. There are 17+ SmileShops around the UK, so if you'd prefer a scan rather than taking your own impressions, Smile Direct Club could be your best option.

Their aligners cost £1,639, making them similarly priced to other brands, but not the cheapest. Included in this price is a premium teeth whitening treatment and any refinements you need at the end of treatment. You also have the option to pay £69.43 per month, but this increases the total cost to £1,805.19.

Throughout your treatment, you'll use their remote monitoring app to track your progress and check in with the dentist monitoring your treatment. Their UK-based customer service team is also on hand if you need any assistance.

It's completely free to book a scan, but if you can't make it to one of their SmileShops, you have the option to purchase an impression kit to do at home.

SmileDirectClub aligners are suitable for mild and some moderate cases. See if you're a good candidate with a free online assessment.


NewSmile is another affordable alternative to Invisalign in the UK. Their aligners are made from Raintree Essix plastic, which is the clearest plastic for aligners available on the market today.

Your scans or impressions are used to plan your treatment

NewSmile don't have any clinics in the UK, so you'll need to order an impression kit to do at home. One of their Impression Specialists can jump on a video call to talk you through this process, if needed. Once your impressions are done, NewSmile will send you your aligners plus a free whitening treatment and your first set of retainers.

If you don't want to wear your aligners during the day, NewSmile offers nighttime aligners. The process is the same as for the daytime aligners, with the only difference being that you wear your aligners for 10 hours at night. Your treatment time will likely be longer than with daytime aligners, but some people prefer this option over wearing aligners during the day.

NewSmile offers both upfront payment and payment plans. Their ‘Fast Track' payment requires a one-off payment of £1,295 for daytime treatment or £1,395 for the nighttime treatment. This price includes the impression kit, treatment preview, aligners, retainers, and whitening. If it turns out you're not eligible for treatment, you'll get a full refund.

You can also choose to buy the impression kit separately for £39, or take advantage of an interest-free payment plan.

Straight My Teeth

Straight My Teeth was one of the first brands to offer a cheaper alternative to Invisalign with remote aligners. Their full package costs £1,199. Currently they are not accepting any new patients, though. We recommend you choose one of the two options above if you're looking for affordable aligner treatment.

Straight Teeth Direct

invisalign alternative at home
All these aligner brands look much the same

Straight Teeth Direct is the only one of these companies to guarantee that an orthodontist will be overseeing your treatment. This is a good selling point – after all, orthodontists are specialists in the field of teeth straightening.

Their aligners cost £1,550, making them mid-range in terms of price, and they have one clinic in London which you can visit for scans – although they charge £79 for this appointment.

If you want to be sure an orthodontist is monitoring your treatment and you don't mind paying a bit extra for that benefit, this could be the best choice for you. Our Straight Teeth Direct review has more details.

In-office Invisalign Alternatives

If you need more significant teeth straightening than is offered by these remote orthodontics companies, or you'd just prefer the assurance of regular face-to-face checkups, here are some in-office alternatives to Invisalign treatment for you to consider.


ClearCorrect was founded in 2006 and is the main competitor to Invisalign in the UK. The process and experience for getting these aligners are quite similar to the Invisalign system. Your dentist or orthodontist must register to be a ClearCorrect provider, and then ClearCorrect sends them the materials needed to straighten your teeth.

You have regular in-office visits with your dentist or orthodontist as you would with regular braces. ClearCorrect aligners are made from thinner material than Invisalign aligners, which their website claims make them less noticeable. It could be argued that the thinner aligners are more prone to break, while others say they are more comfortable.

Then there's the price. ClearCorrect market themselves as a cheaper Invisalign alternative, and you might save a few hundred pounds by choosing them. However, they still aren't as cheap as at-home solutions, except perhaps for very mild cases. Read more about ClearCorrect vs Invisalign in our separate guide which explores these two brands in more detail.

Quick Straight Teeth

Quick Straight Teeth, and similar competitors Six Month Smiles, work on just the front six to eight teeth to make treatment as quick and affordable as possible. You still visit a dentist throughout the treatment, so you could see these as an in-between option if you don't need Invisalign Comprehensive but do still want in-office treatment.

Summary of in-office alternatives to Invisalign treatment

Below is a quick summary table comparing some of the in-office Invisalign equivalents. Others like Smilelign aligners, ClearSmile, Inman Aligners and Six Month Smiles are all similar options that your dentist might offer.



Quick Straight Teeth





Suitable for mild problems?




Suitable for mid-level problems?



Maybe (only front 6-8 teeth)

Suitable for complicated problems?

Often yes

Probably not



£2,000 - £3,000 (Express)
£2,500 - £4,000 (Lite), £3,500 - 5,500 (Full)

£1,800 (minor treatment)- £4,500

£1,150 - £1,750 per arch (£2,500 + for 2 arches)

Treatment timeframe

3 - 24 months

3 - 18 months

4 - 6 months

Prices correct at time of writing but may change at any time.

If it turns out you don't like any of these at-home or in-office options, you may want to consider a hybrid option like Impress Aligners.

Are at-home aligners really a good alternative?

Invisalign is arguably one of the most popular in-office brands. However, there are really good alternatives available with at-home solutions like NewSmile or SmileDirectClub. With direct-to-consumer aligners you can order your aligners from home or with a single visit to a clinic for a scan. Then, your aligners are posted out to you and you complete treatment remotely.

We can say that these companies are a good option if you:

  • Want the best price
  • Are happy having your treatment checked remotely
  • Want the convenience of not having to visit a dentist every month
  • Only need mild, or moderate cosmetic straightening
  • Want to whiten your teeth at the same time

On the other hand, Invisalign treatment is a good match if you:

  • Aren't a good candidate for at-home aligners because of the amount of movement your teeth need
  • Prefer face-to-face checkups with a dentist to check your progress
  • Want to use the brand that's been around the longest in the UK
  • Would like to benefit from the expertise and advanced technology gained from treating over 11 million patients worldwide


cheap invisalign alternative
There are many cheaper alternatives to braces and Invisalign aligners

Nowadays, there are a plethora of options for those looking to straighten their teeth. Not only are there countless alternatives to traditional metal braces, but there are also many alternatives to clear aligners like Invisalign. If you want to read more about our top picks, check out our article on the best teeth aligners in the UK.

Some of these alternatives are much more affordable and convenient with remote treatment options. The one that we most recommend for those on a budget is NewSmile, who offer great value for £1,295.

The Invisalign system is a proven alternative to metal braces in around 90% of orthodontic cases, so it's a great option if you need that extra level of treatment.

Regardless of the option you choose, we always recommend scheduling a general checkup with your dentist before starting any at-home treatment. It's important to deal with any untreated cavities or gum disease before wearing aligners and your dentist could assess your overall suitability for the treatment you choose.

We hope our guide has helped you figure out the best option for your smile!


Is Invisalign the best clear aligner brand?

With over two decades of experience and research behind them, the Invisalign system is certainly the most established. But it may not be the best for you if you're on a tight budget. Some Invisalign competitors do come in with a lower price tag.

What are the best Invisalign competitors?

The best Invisalign alternative is going to be different for each individual. That being said, if you are looking for a cheap Invisalign alternative, you can opt for at-home aligners. Some of the best brands in the UK include NewSmile, Smile Direct Club or Straight Teeth Direct. 

Alternatively, if you want to visit a dentist in person, you'll have brands like ClearCorrect, Smilelign and Quick Straight Teeth to choose from as alternatives to Invisalign. You might save a little on your treatment with these brands – or you might not. The Invisalign system has several options to treat different degrees of malocclusion.

Is there a cheaper alternative to Invisalign?

It depends how much movement your teeth need, and what type of braces you would like. If you want to stick with clear aligners, a cheap Invisalign alternative might include online or at-home options. NewSmile, Smile Direct Club or Straight Teeth Direct are just a few of the names that have flooded the remote-care clear aligner industry in the past few years.

With a full treatment package costing just £1,295, NewSmile is the cheapest Invisalign alternative we've featured here. Despite the low price tag, your treatment is planned and monitored by a licensed dentist or orthodontist, so you can be sure you're in good hands.
