About Diamond Whites Aligners

Diamond Whites, also known as DW aligners, is an at-home clear aligner brand based in the United Kingdom. It’s co-founded by celebrity dentist Dr. Richard Marques. 

Clear aligners are removable teeth-straightening devices that are a convenient and cost-effective alternative to metal braces.

In recent years, do-it-yourself (DIY) dentistry and orthodontics have increased in popularity. Because they remove in-person dental office visits, companies like Diamond Whites can offer treatment for significantly less money than traditional options.1

Diamond Whites aligners are available as standard or nighttime, and the company also offers teeth whitening kits. Although your treatment is home-based, you can visit the London clinic or a pop-up clinic for initial dental scans if you prefer.

The Diamond Whites Difference

With traditional braces, you’ll visit the orthodontist for regular evaluations and adjustments. However, with Diamond Whites, a team of UK dental professionals will monitor treatment remotely. 

Your treatment includes a special device called the ScanBox. This attaches to your smartphone and allows you to take photos of your teeth to share them through the linked app.

You can opt to take your initial dental impressions with an at-home impressions kit or visit one of the Diamond Whites locations for dental scans.

With Diamond Whites, you’ll receive your entire treatment plan upfront — a series of custom-made, invisible aligners that you’ll change out every 2 weeks. 

These at-home clear aligners work like metal braces by gradually moving teeth into their desired position. As your teeth move, you’ll use the next tray in the sequence until you’ve completed treatment. Treatment length depends on your case, but it lasts 6 months on average.2

The aligners are made with almost invisible material. They’re also removable, so you can take them out for eating, drinking, and brushing your teeth.

For minor cases of teeth misalignment, such as crowded teeth or gaps, Diamond Whites could be a good option. However, an orthodontist may recommend traditional braces or another treatment if you have more complex dental issues.

How Does Diamond Whites Work?

Diamond Whites are clear aligners that use gentle pressure to move teeth into their desired position gradually. They work on the front 6 to 8 teeth.2

You’ll take impressions of your teeth at home using a kit or visit the London clinic or one of the 60 pop-up clinics. With either option, you’ll receive a free at-home teeth whitening kit. A team of dental professionals then reviews your impressions and develops a treatment plan.3

You’ll receive a series of custom-made, clear aligners that you’ll change every two weeks. To track your treatment progress, you’ll submit regular photos of your teeth using the ScanBox and Diamond Whites app.

Treatment Process

The treatment process is as follows: 

  1. Complete the online eligibility questionnaire.
  2. Purchase a home impression kit or visit a partner clinic for dental scans to confirm eligibility.4
  3. If everything looks good, an orthodontist will create an at-home aligner treatment plan for you to approve. If you’re not a suitable candidate, you’ll receive a full refund.
  4. You’ll receive before and after 3D visuals of your teeth and future straightened smile.
  5. If you’re happy, you’ll pay the outstanding balance for your aligners.
  6. The Diamond Whites team will create custom aligners from your dental impressions.
  7. Within 10 days, your aligners will arrive in the mail. You’ll also receive a ScanBox device for weekly digital check-ins.
  8. With standard aligners, you’ll wear them for 22+ hours daily for optimal results. Nighttime aligners are worn overnight for 10+ hours daily.
  9. You’ll switch to the next set of aligners in the sequence every 2 weeks. 
  10. The dental team will monitor progress using the weekly photos you submit with the ScanBox and app.
  11. You can attend a Diamond Whites partner clinic for free care and support if you have any problems during treatment.

How Long Does Treatment Take? 

Treatment time depends on the severity of your dental crowding or spacing. On average, people who use Diamond Whites for simple teeth-straightening needs can expect to wear their aligners for 3 to 6 months.4

Depending on how well you follow the treatment plan, completing treatment could take longer or shorter than average.

Following treatment, you’ll also need to wear retainers day and night for at least a week, then nightly for a set period. The retainers protect the results by preventing teeth from shifting to their original positions.

Diamond Whites Aligner Options

Diamond Whites offer a standard clear aligner and a nighttime aligner option.

Standard Aligners

The standard aligner is made of high-quality, comfortable, BPA-free, clear plastic. The aligners are manufactured in the UK. 

These aligners are barely visible. You’ll wear them for at least 22 hours daily, but you can remove them for eating and oral care. The average treatment time is between 3 and 6 months. 

These aligners cost £1,600.4

Nighttime Aligners

Diamond Whites also offers Nighttime Aligners that you wear for 10 hours overnight. The average treatment time is 5 to 6 months.

These aligners cost £1,700.4

Note: NewMouth warns against using nighttime aligners because dental experts are unsure about their safety and efficacy.

Diamond Whites Cost and Financing Options

The cost of Diamond Whites aligners depends on if you opt for standard or nighttime aligners:

  • Standard aligners cost £1,600.
  • Nighttime aligners cost £1,700. 

You’ll also need to pay £99.99 for impressions or scans. If you pay upfront, these services are free. 

Following treatment, Diamond Whites recommend wearing retainers to maintain results. A set of retainers costs £200.2

Payment Plans

Diamond Whites offer payment plans. Here’s what you’ll pay every month for Diamond Whites treatment with standard aligners:5

  • £133.33 monthly for 12 months. 0% interest.
  • £50.83 monthly for 36 months. 9.9% interest.
  • £33.32 monthly for 60 months. 9.9% interest. 

If you opt for nighttime aligners, you can expect to pay the following in monthly payments:6

  • £141.66 monthly for 12 months. 0% interest.
  • £54.01 monthly for 36 months. 9.9% interest.
  • £35.40 monthly for 60 months. 9.9% interest.


Most dental insurance policies don’t cover orthodontic treatment. If you have insurance, you’ll need to check with your provider to see if they cover the cost of Diamond Whites aligners.

Diamond Whites does not disclose if they accept insurance or not. But, if your policy covers orthodontic treatment, you can submit reimbursement receipts directly to your insurance provider.

Is Diamond Whites Right for You?

Diamond Whites is a good choice for adults looking for economical aligner treatment for mild to moderate crowding or spacing issues.

Treatment is also an option if you’ve had a relapse after wearing braces in the past. But, these aligners don’t move molars and can’t address severe dental problems like overbites, underbites, or crossbites.

An orthodontist can recommend a comprehensive orthodontic treatment plan if you have more complex dental needs. This may include alternative clear aligners like Invisalign. Although Invisalign uses similar technology, it’s a U.S. Food and Drug Administration (FDA)-approved treatment. Orthodontists oversee the treatment during in-office visits. 

Traditional metal braces may also be an option for people with complex dental problems.

Diamond Whites may be right for you if your teeth have small gaps, uneven spacing, or crowding. It’s also a good option for people who can complete treatment without in-person support.
