Best Clear Aligners UK

Braces aren’t the only way to get straighter teeth. Clear aligners are another alternative you can look into. These are plastic dental trays that work like braces—they apply pressure to straighten your teeth while worn. 

However, aligners are cheaper and more convenient, and most brands offer remote progress monitoring or require fewer dental visits. 

They’re also more comfortable and less visible than braces. Although their biggest advantage is that you can remove them anytime.

Several companies currently offer clear aligners in the UK. We’ll help you pick one that best suits your needs and budget.

To help you decide, we asked our in-house dental experts at NewMouth to evaluate clear aligner brands in the UK based on the following criteria:

  • Overall user experience (30%)
  • Treatment process (30%)
  • Pricing and financing (20%)
  • Customer service and aftersales support (15%)
  • Brand reputation (5%)

Why We Recommend It

  • According to some reviews, Invisalign has poor customer service and retainers that break easily and may cause cuts or discomfort.
  • 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.

Invisalign is the most trusted in-office clear aligners in the United Kingdom. Since its launch, the company has treated over 15.7 million people.

Virtuoso Highlights

Available TreatmentsUpper and lower teeth aligners
Monthly PlansDepends on provider
What’s IncludedFree online consultation, dental visits, retainers, dental scope, toothpaste, aligner case, aligner accessories, and the Instant Dentist app (for remote monitoring)

Why We Recommend It

  • Virtuoso offers personalised treatments. Depending on the severity of your condition, your provider may schedule more or fewer dental visits.
  • The treatment cost includes digital teeth scans, in-office visits, a set of retainers, and any refinement aligners you may need for straighter teeth.
  • The dental scope included with your kit makes it easy for your assigned dentist to watch your teeth straightening progress while you’re at home.

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 as Straight Teeth Direct. The only dental practice offering its aligners are located in Berkshire.

More Invisible Aligner Brands in the UK

Here are more companies that offer clear aligners to UK locals:

ClearCorrect

Cost: £1,200 to £4,500

ClearCorrect is a reliable, effective, and affordable alternative to Invisalign. It treats different types of misaligned teeth, including severe cases, and you’ll be asked to visit the clinic regularly. During these visits, your dentist or orthodontist can fit the aligners, replace them, and adjust your treatment.

Diamond Whites (DW Aligner)

Cost: £1,490 to £1,990

Diamond Whites (DW) offers at-home daytime aligners for straightening mild to moderately crooked teeth. You can pay for the treatment upfront or visit one of 60 dental clinics and pop-up locations to begin treatment. 

Spark Clear Aligners

Cost: £1,899 to £8,000

Spark is an in-office aligner available through Spark Providers. The brand is partnered with several local orthodontists in the UK. To get started, you would have to visit one for an in-person scan. Once you receive your Spark Aligners, treatments can be monitored in person or virtually.

Choosing Between In-Office vs. At-Home Aligners in the UK

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 NewSmile work on mild to moderate teeth misalignments.

You should talk to a registered dentist or orthodontist to determine which orthodontic treatment suits 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 to begin treatment.

In-office treatment requires you to visit a provider in your area for an initial consultation and to see them regularly throughout the treatment.

Most at-home aligner companies offer 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 is best for you.

Most clear aligner companies offer daytime and nighttime aligners, or aligner treatments based on the severity of your condition. You get to choose your treatment.

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.

Most brands of invisible aligners offer financing. This allows you to pay for your treatment with affordable monthly installments.

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.
