What are Clear (Invisible) Aligners?

Invisible aligners are clear plastic trays that fit over your teeth and slowly move them in small increments. They’re a removable, comfortable, and convenient alternative to traditional braces.

Aligners typically straighten teeth in less than a year. Treatments might take less than 6 months if you have mild teeth misalignment.

Two types of aligners are available in the UK: in-office and at-home.

In-Office Aligners

Invisalign is the most established in-office aligner. You must visit an Invisalign-certified doctor to begin the process and set up routine check-ups throughout treatment.

Invisalign can be expensive but offers the best care overall. It's especially recommended if you have moderate to severe teeth misalignment.

At-Home Aligners

At-home aligners are a convenient and more affordable alternative to Invisalign. However, it's best recommended for mild teeth misalignment only.

You begin treatment remotely by taking impressions from home. Then, send the impressions back to have a treatment plan created. The entire process is monitored remotely, which means you never visit a dentist in person.

6 Best Clear Aligners in the UK

Many clear aligner brands are on the market today, making it easy to find one that fits your lifestyle, budget, and needs. Most aligners we recommend are at-home options (best for mildly misaligned teeth).

We also recommend an in-office aligner if you’re looking for comprehensive care, have moderate to severe misalignment, and don’t mind the higher price tag.

Based on our research, here are the top aligners available in the UK:


Best At-Home Aligners

SmileDirectClub (SDC) is the most well-known remote aligner. They’ve treated over 1.5 million patients since 2013 and expanded treatment to the UK in 2019.

SDC works with registered doctors, dentists, and orthodontists who create and oversee each treatment case.

There are two ways to begin treatment: order an online impression kit for £39 or visit a SmileShop for a free consultation (3D images/scan). There are currently more than 20 SmileShop locations in the UK. 

You’ll receive a full refund on the impression kit if you aren't a candidate. The scan is also risk-free. 

Cost: The Regular Aligners and Nighttime Aligners™ both cost £1,639 or £1,805.19 financed at £69.43/mo for 25 months

Treatment Time: 4 to 6 months, depending on your plan


Budget Option

NewSmile works with a network of dentists and orthodontists to ensure you get the best custom clear aligner treatment. They are licensed by Health Canada and are U.S. FDA-approved.

NewSmile has the NewSmile™ Monitoring App to ensure dentists can check your treatment progress. All of this is completed from the comfort of your home.

You can order an impression kit on their website for £39. If their dentists determine you are not a candidate for treatment, you can request a refund.

Once you have your impression kit, book a video call with their team of professionals to guide you during the process. After, you will mail your impressions using your pre-paid label.

When you approve your treatment plan, NewSmile will mail you all your aligners, and you can begin treatment. The process takes an average of 4 to 6 months.


  • Day Time Aligners — £1,295
  • Night Aligners — £1,395

Payment Plan:

  • Day Time Aligners — £108/mo for 12 months with potentially no down payment
  • Night Aligners — £116/mo for 12 months with potentially no down payment


Best Hybrid Treatment

DrSmile offers a hybrid treatment option for people in the UK. Their aligners are made from ClearQuartz® Material in Germany and the US to ensure durability and flexibility.

To begin treatment, locate the nearest DrSmile partner practice in your area. You will book a free initial consultation, so your dentist can take detailed 3D scans of your teeth and plan your treatment.

Orthodontists specializing in aligner treatments will examine and prepare your treatment plan. Once done, they will show you a 3D simulation of the plan. If you approve the plan, all you need to do is pay and wait to receive your aligners in the mail and begin treatment.

If your treatment results are not as shown in the simulation, DrSmile guarantees to cover all further treatment costs until you achieve your dream smile. You can also use the DrSmile app for any questions or concerns throughout your treatment.

Cost: Between £1,390 and £2,090, depending on your dentist's assessment

Treatment Time: 6 to 12 months, depending on your plan


Hybrid Option
Virtuoso Logo

Virtuoso is a newer aligner company that offers UK residents a hybrid treatment option similar to Invisalign. They are most suited for minor teeth misalignments, such as gapped, crowded, and overlapped teeth.

The process starts with an online consultation, followed by an in-person appointment with a Virtuoso provider in your area. During the appointment, you can clarify the details of your treatment.

After your dentist has 3D scans of your teeth, they'll process your aligners. Once they're made, you'll receive your aligners at the clinic.

Your dentist will check that your aligners fit well during this appointment. Once done, they will monitor your progress through the Instant Dentist app and in-person appointments.

Aside from your first aligners, you will also receive:

  • Connected Dental Scope
  • Full-size Regenerate toothpaste
  • Aligner protective case
  • Aligner accessories (chewies, retriever, and file)
  • Patient wear and care manual

Cost: Virtuoso offers a flat price of £1,999 for upper and lower aligners.

Treatment time: The average time people complete their treatments is between 6 and 9 months.

Straight Teeth Direct

Best Remote Aligner
Straight Teeth Direct

Straight Teeth Direct is one of the most popular at-home aligners in the UK. Unlike PlusDent and Invisalign, you don’t have to visit a provider for an initial consultation.

Instead, the treatment process begins with a quick online questionnaire. You’ll be asked:

  1. What you’d like to improve (e.g., teeth alignment, gaps, crowding)
  2. To upload photos of your teeth
  3. Other questions related to your dental health and alignment issues

After completing the form, you’ll have the option to order a SmileBox™ (impression kit). You’ll take these yourself and send them back within a few days. This kit costs £69. A trusted dentist will review your case and create a custom treatment plan if you’re a candidate.

If you live near Central London, you can opt for a professional 3D scan (in person) to get a digital impression of your teeth. These scans are more detailed than at-home impressions and cost £79. 

Once you approve the plan, Straight Teeth Direct will send the aligners to your home in stages. You’ll use an app to check in monthly with your assigned dentist. This specialist will adjust your treatment and aligners to ensure your teeth are moving correctly.

Cost: £1,550

Payment Plan:

  • Three installments — £560 upfront, then £560 2 and 4 months later
  • Monthly — £499 upfront and £169/mo for 8 months
  • Finance — Pay through Humm, an external credit provider (credit check required), starting from £49.14/mo

Treatment Time: 5 to 9 months, depending on your plan

Straight Teeth Direct offers completely remote treatment from start to finish. Every treatment case is assigned a dentist who reviews and monitors progress via an app. They also offer more guarantees than other at-home aligners.


Best In-Office Treatment

Invisalign is our #1 recommendation for in-office aligners because it can treat 90% of orthodontic cases. This includes more severe malocclusions (teeth misalignment) like:

  • Overbites
  • Underbites
  • Crossbites

Invisalign is the most well-known clear aligner brand. It has been around since 1997, treating over 14 million patients (and counting) around the world.

Invisalign aligners use buttons or elastics to treat more severe cases. These are small hooks that attach to the tooth surfaces. They act as anchors for interarch bands that apply additional pressure to gradually reposition the jaw, providing more precise results. Small rubber bands help shift the jaw into the correct position.

You’ll also receive the best care overall with Invisalign. The treatment process and monitoring are very comprehensive because you see a specialist for check-ups throughout treatment. 

The interactive ClinCheck Software helps you track your progress from the beginning. If any changes are needed mid-treatment, the orthodontist or dentist can easily make them.

Regular, in-person visits allow for quick adjustments to ensure your treatment stays on track. This is more difficult, but not impossible, with remote options.


  • Invisalign Full and Invisalign Teen — between £1,500 and £5,500 (best for those with moderate to severe misalignment)
  • Invisalign Lite — between £2,500 and £4,000 (best for minor misalignment)
  • Invisalign i7 between £1,400 to £3,000 (best for those who only need minor corrections)

Payment Plan: Many Invisalign providers offer payment plans or discounts, but it depends entirely on your treatment plan and length.

Treatment Time: 3 to 12 months, depending on your plan.
