Pros, Cons & Costs (2024)
Fixed braces used to be the only way you could straighten teeth. You can try clear aligners if you want practical alternatives in the UK.
Aligners are clear plastic trays that fit over teeth and gradually shift them into alignment. They work similarly to braces but have a few benefits:
- Aligners are removable alternatives to braces
- Some teeth aligners don’t require you to visit a dentist
- They can give you a straighter smile in as little as 6 months
- They’re usually less painful than traditional braces
- Clear aligners are less visible compared to metal braces
- Aligner treatment is cheaper and easier to access
Clear aligners work on mild to severe teeth misalignments. Other names for them include invisible aligners, teeth aligners, and teeth straighteners.
Several clear aligner companies currently offer these treatment options. To help you choose, we compared the best teeth aligners in the UK.

NewSmile
Best At-Home Teeth Aligners
Editor’s Choice
Why Choose NewSmile?
NewSmile is our top pick for at-home aligner treatment in the UK. Its aligners use the same high-quality material as Invisalign but don’t include the expensive price tag.

Smile White
Best for Fast Teeth Straightening
Why Choose Smile White?
Smile White can straighten teeth in as little as 2 to 7 months, faster than most invisible aligners in the UK.
It’s also a great option if you’re after specific results. You can straighten only your upper or lower teeth (single arch) or both (dual arch).
Smile White uses the same high-grade plastic as Invisalign for its aligners. However, its affordable treatments make it a better alternative.

Invisalign
Best In-Office Aligner Treatment
Why Choose Invisalign?
Invisalign can treat 90% of orthodontic cases, including severe teeth misalignment and bite problems. It’s our most recommended in-office clear aligners.
You’ll be working with an Invisalign provider throughout the treatment. These are UK-registered dentists or orthodontists who can:
- Determine if you’re a good candidate for Invisalign
- Perform dental work to help you qualify for the treatment

Many UK dentists and orthodontists offer Invisalign treatment, making it easily accessible. Seeing a dental professional for your initial Invisalign assessment and treatment helps ensure you receive personalised care.

- Additional costs may incur if you switch to a new provider, if your treatment lasts longer than planned or if you need to replace broken retainers.

Virtuoso
Best Hybrid Aligner Treatment
Why Choose Virtuoso? Virtuoso provides comprehensive yet convenient treatments by combining in-office care with remote treatment.
You need to see a Virtuoso provider at the start of the treatment. They’ll assess your dental health to make sure you’re qualified.
After this initial assessment, your assigned dentist will create your treatment plan and schedule both dental visits and online check-ins.

Average Treatment Time | 6 to 9 months |
Treatable Cases | Mild to severe teeth misalignments |

Why Consider Other Brands
- There isn’t enough information on available financing. We don’t recommend it if you prefer paying for your treatment in monthly installments.
- Virtuoso is a relatively new clear aligner brand in the UK. It only launched in 2022 and has limited customer reviews.
- Since it’s a new brand, there are very few Virtuoso providers across the UK. This can limit your access to the hybrid treatment.
Virtuoso is under the same company that offers Straight Teeth Direct. Its locations are currently limited to Berkshire, London, and Preston.
More Invisible Aligner Brands in the UK
Here are more companies that offer clear aligners to UK locals:
ClearCorrect
ClearCorrect is a reliable and effective way to straighten teeth. It treats different types of misaligned teeth, including severe cases.
Much like Invisalign, you’ll be asked to visit the clinic regularly. Your dentist or orthodontist can fit the aligners into your teeth, replace them, and adjust them as needed.
ClearCorrect UK typically costs £1,800 to £3,000. This makes it an affordable Invisalign alternative if you’re looking into in-office treatments.
Diamond Whites
Diamond Whites (DW) offers both daytime and nighttime treatment. Its at-home aligners treat mild to moderately crooked teeth.
There are two ways to begin treatment with DW aligners. You can order impression kits or visit one of its popup locations across the UK.
Treatments with Diamond Whites cost £1,990. Unfortunately, this won’t include retainers which may cost you £200 per set.
Smile Direct Club
SmileDirectClub is a brand of at-home clear aligners.
The company announced its bankruptcy liquidation on September 2023, ceasing aligner treatments and ending its lifetime guarantee.
Its global operations closed on December 2023 after failing to secure the funds needed to buy itself out of bankruptcy.
How this affects you will depend on which stage of the treatment process you’re in. You can read our customer guide for SmileDirectClub UK.
Choosing from In-Office vs. At-Home Aligners
Here are five things to consider when deciding on the best clear aligner for your needs:
1. Level of Teeth Misalignment
You can choose from in-office and at-home clear aligners depending on your condition.
In-office clear aligners like Invisalign work on mild, moderate, and severe cases. At-home clear aligners such as StraightMyTeeth and NewSmile work on mild to moderate teeth misalignments.
You should talk to a registered dentist or orthodontist to determine which orthodontic treatment is for you. They can help you explore alternative options, such as clear braces or invisible braces.
2. Treatment Accessibility
Pick a clear aligner brand that makes it easy for you to begin treatment.
In-office treatment will require you to visit a provider in your area for an initial consultation. You also need to see them regularly throughout the treatment.
Most at-home aligner companies offer free teeth impression kits. Although some brands may give you the option to visit a specialist for an in-person scan.
3. Treatment Options
Consider which treatment options are available before deciding on a brand.
In-office clear aligner systems tend to offer structured treatment plans based on your age and condition. Your provider will help you decide which aligner therapy is best for you.
Most clear aligner companies offer daytime and nighttime aligners. You get to choose your treatment. But keep in mind that night aligners may be unsafe and ineffective.
4. Treatment Costs
At-home clear aligners are less expensive than in-office aligners. You want to compare the costs of different brands and find one that fits your budget.
You can use qualified dental insurance to reimburse some of the treatment costs. Be aware of any price differences if you pay in full or monthly installments. Other costs to consider are:
- Impression kit (if it isn’t included with your aligner kit)
- Retainers after completing treatment
- Lost or stolen clear aligners
- Touch-up aligners or refinement
If you’re not satisfied with the results of your clear aligner therapy, some brands may offer a lifetime smile guarantee to cover the cost of new aligners. Others may charge for refinements.
5. Treatment Duration
Go for a brand that can give you results within an acceptable time frame.
Each brand has a different average treatment time. This will help you gauge how long you must undergo treatment before you see results.
Remember that the time it takes to get straight teeth will depend on your condition and if you follow the prescribed wear schedule for all your aligners.

NewMouth Rating System
We ordered the best kits that met our criteria and had in-house writers test them out throughout their prescribed treatment.
While testing the clear aligners, our team assessed and scored them based on five traits. Each trait was assigned a “weight” so we could calculate their individual rating and weighted average scores on a scale of five.
Here is how we rated the best clear aligners on our list:
Customer Experience
Using artificial intelligence, we gathered and analyzed feedback from hundreds of people who tried our list of clear aligners.
This helped us determine the users’ experiences with a brand, including:
- Its availability for in-person and/or virtual consultations
- The accessibility of its clear aligners and ease of ordering
- Whether it gives clear instructions for taking teeth impressions
- The fit and comfort of its invisible aligners when worn
Treatment
We compared the brands’ average treatment times and effectiveness for correcting mild and moderate teeth misalignment.
Our team also examined them for any products or services they provided that would help customers during and after their treatment, such as:
- Access to dental experts who can answer your questions and guide you throughout your treatment
- A dedicated app that reminds users to switch aligners and allows them to conveniently track their progress and contact support
- Regular virtual and/or in-person check-ins with a dental professional who can ensure that your treatment is going well
- Dental treatments such as complimentary teeth whitening
Pricing and Financing
We explored the total treatment cost of invisible aligners, including their upfront prices, flexibility of payment options, eligibility for insurance, and maintenance costs for additional retainers.
Customer Service and After-Sales Support
Our team performed an in-depth investigation of each brand’s customer support when answering queries and resolving issues. We assessed their:
- Availability
- Responsiveness
- Knowledge
- Reliability
- Friendliness
We also checked companies to see if they offered guarantees for clear aligner adjustments, refinements, replacements, or refunds if you’re not qualified or if the treatment doesn’t work for you.
Brand Reputation
With the help of advanced AI algorithms, we were able to sort through hundreds of customer reviews that would indicate the level of trust they had in a clear aligner brand.
Common Questions about Clear Aligners
How do I start my clear aligner treatment?
If you opt for in-office aligners such as Invisalign, you’ll need to visit a dentist or orthodontist who offers them.
At-home aligner treatment usually begins with you taking an online quiz and buying a teeth impression kit online.
However, some at-home clear aligner companies have physical locations that you can visit for an in-person consultation.
Which conditions can clear aligners treat?
Invisible aligners are used to correct crooked teeth and some bite problems. These include:
Gapped teeth
Crowded teeth
Crossbites
Overbites
Underbites
In-office invisible aligners work on mild to more severe alignment issues. Meanwhile, at-home clear aligners only treat mild to moderate conditions.
What is the cost of clear aligners in the UK?
In-office clear aligners may cost £1,800 to £5,000. At-home aligners typically cost £1,500 to £1,700. Hybrid aligners cost £1,400 to £3,700.
How long does clear aligner treatment take?
In-office aligner treatments have an average treatment time of 12 to 18 months. At-home aligner treatments usually work for 4 to 10 months.
Your treatment may last longer or shorter, depending on your condition.
Do clear aligner companies offer payment plans?
Yes. Most brands of invisible aligners offer financing. This allows you to pay for your treatment with affordable monthly installments.
Does insurance cover invisible aligners?
In most cases, you can use your dental insurance to cover a portion of your treatment costs. Ask your insurer if your plan covers clear aligners.
How often do I need to wear my custom aligners?
Daytime aligners must be worn for 20 to 24 hours daily. Night-only clear aligners should be worn for at least 10 continuous hours in the evening.
Make sure to follow the prescribed wear time for your removable aligners. You can remove them when eating, brushing, or flossing your teeth.
What if my aligner treatment doesn’t go as planned?
Talk to your provider or reach out to customer support. Ask them what they can do to help you achieve the results you want.
A provider or clear aligner company may provide free refinements or charge you for additional aligners, depending on their policies.
What are home teeth aligners made of?
Teeth aligners are made of clear medical-grade plastic. They’re BPA-free and phthalate-free so they’re safe to wear.
Does it hurt to wear invisible aligners?
Invisible aligners shouldn’t be painful the entire treatment.
You may experience discomfort when wearing the aligners, but this should subside after a few weeks.
What happens after my aligner treatment is complete?
You’ll need to wear aftercare retainers to maintain your new smile.
Retainers have to be worn indefinitely for several hours each day so your teeth don’t shift back to their original place.
