Straight My Teeth is one of the best clear aligners in the UK. The company initially launched in Ireland back in 2018. It has since expanded to the United Kingdom and the United States.

Based on Trustpilot reviews, most people seemed happy with the brand up until August 2022. They were satisfied with its customer service and cheap yet effective teeth straightening.

Straight My Teeth started receiving mostly negative reviews in September 2022. At the time, users say the company became unresponsive, and orders weren’t being shipped out.

Our review covers both positive and negative feedback from its customers. We also included our own experience with Straight My Teeth before it went off the radar.

Straight My Teeth Pros

“It was a great and fulfilling journey with Straight My Teeth. The staff (Sarah) was very supportive and quick with the response. Moreover, I was satisfied with the result after 12 months of using their NightAdvantage scheme.”

“I am happy that I achieved [these] straighter teeth and confident smile after a year compared to a 4-year dental [bracket] I went through before. Aside from the fact that it is the [least] expensive aligners on the market, it is the most effective. I will always recommend this to anyone.”

Straight My Teeth Review on Trustpilot

  • It effectively straightens teeth. Several users are happy with the results of their treatment. Unlike most at-home aligners, it can correct overbites and overjets.
  • Straight My Teeth is the most affordable teeth straightening treatment in the UK. You can purchase its clear aligners for £400 to £500 less than what competitors offer.
  • It has a faster treatment time than most competitors. Other brands usually take up to 10 months. Straight My Teeth can give you a straighter smile in as little as 4 to 8 months.
  • You’ll get value for your money. Treatment costs include up to 9 free retainers and a teeth whitening kit if you opt for an in-person consultation.
  • The customer service is helpful. When the company was still actively taking orders, they responded quickly and provided assistance throughout the treatment.
  • Starting treatment is easy. The treatment process is straightforward and convenient whether you decide to get a consultation or an impression kit. 
  • It gives you different ways to pay for your treatment. You can pay upfront, with private insurance, or with low-interest financing options.
  • Straight My Teeth offers a few guarantees. The company can refund impression kits (if you’re not qualified) and replace ill-fitting aligners at no extra cost.

Straight My Teeth Cons

“I have to say I completed my treatment with Straight My Teeth and had a really positive experience with them. My teeth are much straighter than before however, the last set of aligners didn’t quite push together the last bit of gap between two of my teeth, so I feel I would have needed 1 or 2 more aligners to extend the treatment, which hasn’t happened due to them going bust.”

“Overall, though, my teeth are in much better condition than they were prior to starting treatment, and the slight gap left I plan to get some composite bonding (as originally planned) to sort this out and make my teeth look even better. I can’t stress enough that up until the end, I had no problems whatsoever…”

“The treatment can be painful and I had some gaps created in my teeth during the treatment but this was to be expected as my teeth had to move to become straighter. The gaps do close throughout the treatment.”

“I’m fortunate to have got to the end of my treatment and only have some mild adjustments that can be made elsewhere. I wouldn’t be happy if I [were] halfway through treatment so I do feel for people who have been left!”

Straight My Teeth Review on Trustpilot

  • Its products are reported to have poor quality. Based on reviews, you may receive clear aligners or retainers that break easily or don’t fit properly.
  • Straight My Teeth may not get your teeth straightened. Few people say it failed to meet their expectations. You may need more aligners to achieve the desired outcome.
  • Refinement aligners aren’t free. Straight My Teeth charges £300 for additional refinements if you’re not satisfied with the results of your treatment.
  • It only has one Smile Studio. Unless you live near Staines-Upon-Thames, you may not be able to get an in-person consultation.
  • Customer service can be difficult to reach. Some people didn’t get the guidance, refinements, or retainers they needed during and after completing the treatment.
  • The company works solely with professional dentists. While dentists also provide teeth straightening treatments, they lack the specialisation of orthodontists.
  • Expect long wait times. Your orders may arrive late or may not arrive at all, causing delays in the treatment. Requesting refunds may also take longer than they should.
  • It isn’t a reliable treatment option. As of this writing, the company isn’t taking any orders. There is no official announcement on its status and where it’s headed.

Who Can Use Straight My Teeth?

Straight My Teeth is suitable for adults and teenagers aged 14 with their full set of adult teeth. This includes older adults ages 50 to 60 years.1

Like most at-home clear aligners, it can treat people with mild to moderate teeth alignment issues. Some of the conditions it can treat are:2

Straight My Teeth can’t correct highly complex issues. People with gum disease, poor oral health, pegged teeth, and severe overcrowding aren’t eligible for the treatment.2

If you have severe malocclusions or bite problems, clear aligner treatment may not be the ideal choice. You may want to consider wearing traditional braces.

How Long Does Straight My Teeth Straighten Teeth?

Straight My Teeth can get your teeth aligned within 4 to 6 months. However, your clear aligner treatment may last longer. Some conditions take a year or more to correct.

The time it takes to achieve your dream smile will depend on your condition, your choice of clear aligners, and if you wear them as prescribed:3,4 Here are the average treatment times:

  • Daytime aligners ⁠— 4 to 6 months
  • Nighttime aligners ⁠— 6 to 8 months

How Much Does Straight My Teeth Cost?

Does NHS Cover Straight My Teeth Aligners?

No. The National Health Service (NHS) doesn’t typically cover Straight My Teeth treatments. However, some people may get approved on a case-by-case basis.

The NHS only covers dental care treatments that are necessary for maintaining oral health. Unfortunately, clear aligners are often considered cosmetic treatments.

If you do request to be covered, the NHS will use the Index of Orthodontic Treatment Need (IOTN) to grade your case on a scale of 1 to 5. It will help them determine your coverage:

  • Grade 1 to 2 — Treatments won’t be covered
  • Grade 3 — Your treatment may or may not be covered
  • Grade 4 to 5 — Treatments are usually covered

Does Insurance Cover Straight My Teeth?

It depends on your insurance coverage. If you have a dental plan that provides orthodontic benefits for clear aligners, your insurer may reimburse a part of the costs.

How Does Straight My Teeth Work?

Here are the steps to Straight My Teeth’s clear aligner treatment so you’ll know what to expect:

Step 1: Choose how you want to start your treatment

If you prefer a fully remote treatment, you can take the free online assessment. They’ll let you order the impression kit once you qualify for the 30-second quiz.

Next, they’ll send you an impression kit with easy-to-follow instructions. You will take your own teeth impressions at home and send them back in the pre-paid return box.

But if you want an in-person consultation, you can schedule an appointment at Straight My Teeth’s Smile Studio in Staines. During your visit, they’ll ask questions and take scans of your teeth.

Your dental impressions or teeth scans will be returned to the company for evaluation.

Step 2: Approve your Straight My Teeth treatment plan

A dental team will review your case to determine if you’re a good candidate. If you are, a local dentist will create a personalised treatment plan and your Smile Projection.

fMG bncSJskoJpH2Rkl3iSSARZhqirCb0TjFkrDCvZa 1n4D14g

The Smile Projection is a 3D image of your future smile. It shows how your teeth will look like at the end of the treatment. At this point, you can decide to cancel or approve the treatment.

If you approve the treatment preview from your assigned dentist, Straight My Teeth will charge you the cost of your treatment. Next, they’ll have your custom aligners made.

Step 3: Complete your teeth straightening at home

When your prescribed aligners are ready, they’ll be delivered to you all at once. Each clear aligner has to be worn for at least 10 days and a certain number of hours:

  • 20 to 22 hours daily if you have daytime aligners
  • 8 to 10 continuous hours if you have nighttime aligners

You can remove them before eating or drinking unless it’s just water. You should also brush, floss, or rinse your teeth between meals before you wear aligners.

Step 4: Maintain your straighter teeth

You have to wear retainers to let your teeth stay in place. Retainers prevent them from shifting back. Straight My Teeth will send your free retainers after completing the treatment.

Once you’ve used up all the free retainers included with your treatment, you have to purchase a new set and replace them every 6 months.

Straight My Teeth vs. Best Clear Aligners in the UK

Straight My Teeth is one of the best clear aligners in the UK, but it isn’t your only choice. You can also pick from in-office aligners, hybrid treatments, and other at-home clear aligners.

Here are the differences between Straight My Teeth and other teeth straightening treatments in the United Kingdom:

Straight My Teeth vs. Invisalign UK

Invisalign can treat 90% of orthodontic cases, including severe teeth misalignment and bite problems. It’s our most recommended in-office clear aligner and requires frequent visits to the dentist’s office.

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
  • Track your progress in person every 4 to 6 weeks

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.

Straight My Teeth vs. 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.

While most brands offer straight-cut aligners, NewSmile aligners are scallop-shaped. They’re more comfortable, barely noticeable, and less likely to irritate your gums.

NewSmile has daytime and night-only clear aligners that cost £1,595 to £1,695. It can treat people with mild to moderate cases in 4 to 10 months.

Straight My Teeth vs. Straight Teeth Direct

Straight Teeth Direct offers affordable orthodontics without sacrificing your convenience, safety, or the quality of your results.

A dental team will track your progress virtually through an app and adjust your treatment based on the movement of your teeth.

Straight Teeth Direct stands out from other at-home options because of its highly personalised approach. This helps ensure customer satisfaction.

For instance, they may ask you to continue wearing your current aligners until they are sure you’re ready for the next batch.

Straight My Teeth vs. Smile White

Smile White is 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.

Smile White can straighten your teeth in as little as 2 to 7 months, faster than most invisible aligners in the UK. It costs £1,695 to £3,695.

Straight My Teeth vs. Dr. Smile

Dr. Smile (formerly PlusDent) offers great value for your money. It corrects most teeth misalignments for a lower price than traditional metal braces and in-office brands like Invisalign.

If your results don’t match your custom treatment plan, the company may cover the cost of any additional aligners you’ll need to get straighter teeth.

Dr. Smile has a treatment time of 6 to 12 months. Treatments may cost you anywhere from £1,390 to £2,090.

Straight My Teeth vs. SmileDirectClub UK

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.
