Please note: Straight My Teeth has unfortunately closed down and is no longer taking orders. If you're looking for an alternative, we recommend you look at our roundup of the best teeth aligners.

Teeth straightening for £1,199? Is it too good to be true? In this Straight My Teeth review we will look at how these aligners work, whether they are safe, and how to decide if they are the right invisible dental brace for you.

We'll also go over:

  • Who Straight My Teeth are
  • How you begin your treatment
  • What Straight My Teeth costs
  • What Straight My Teeth reviewers are saying

We hope this gives you all of the information you need to make the right choice about your dental care.

What is Straight My Teeth?

Straight My Teeth are pretty new to the market, which is why you may not have heard of them before. However, they source their aligners from a well-established company, which holds its own patents and has approval from the FDA in the US and the MHRA (Medicines and Healthcare Products Regulatory Agency) in the UK.

These aligners are a convenient way to get straighter teeth

Their UK office is in Ashford, London (close to Heathrow Airport). This is also the location of their first – and so far their only – Smile Studio.

The team is made up of orthodontists and dental technicians who assess your teeth and design a treatment plan for you. There is also a licensed dentist who works at the Smile Studio who will take 3D scans of your mouth if you choose that option.

Aside from visiting their Smile Studio, all of your interactions with Straight My Teeth in the UK are done over the internet, with a member of the team assigned to your treatment who can help you with any issues.

Contact is done through video or voice calls and you can email them with any questions or problems, too. This is quite different to in-office invisible braces like the Invisalign system, where all your checkups are done face-to-face with a dental professional.

Day or night aligners?

Straight My Teeth offer two treatment plans with clear aligners. The standard system involves wearing your aligners for 20-22 hours a day, with treatment taking 6-14 months on average. You must remove your aligners to eat and drink anything except water, and you must clean your teeth well before putting your aligners in.

But they have recently introduced a new NightOnly package with the following features:

  • Aligners are worn for 8-10 hours per day, usually at night
  • Average treatment 8-12 months
  • Costs £1,299 rather than £1,199
  • More restrictive eligibility

Nighttime clear aligners could be a good option if you really don't want anyone else to see you wearing aligners, or if you want to avoid the inconvenience of removing them to eat. Read more about Straight My Teeth's nighttime aligners here.

How do Straight My Teeth aligners work?

Removable aligners are a modern version of braces. Rather than having metal brackets and wires attached to your teeth, an aligner is a piece of plastic perfectly moulded to your teeth. The action is the same – both braces and aligners apply pressure to your teeth to get them to move over time.

Normally you’d have braces or aligners to fix problems such as:

Solutions to straighten teeth at home like Straight My Teeth can typically handle mild and moderate cases of crowding and gaps in teeth. For more complicated bite problems, you will probably need in-office treatment with traditional braces or a more advanced aligner treatment like the Invisalign system.

In any case, your individual case will be carefully assessed to see if you are a suitable candidate – more on this below.

Once you’ve got your treatment plan and you agree to go ahead, your aligners are created and posted to you. The video below gives an interesting glimpse into how your aligners are created in the lab:

So, if you're wondering whether Straight My Teeth are legit, the answer is yes. They are a genuine company providing a well-established type of treatment.

How to get Straight My Teeth aligners

Now we’ve given you an overview of how things work, we’ll go through the step-by-step process for getting Straight My Teeth aligners in the UK. It’s quite different to the process for getting in-office braces, but the end result will still be a straighter smile – and a healthier bank account than if you'd gone with traditional braces!

Preparation and assessment

It’s really important your teeth are ready to be straightened. If you’ve been to the dentist for a checkup in the last six months then you can continue to the next stage.

Missed your recent checkup? You should have one before starting treatment, to make sure your teeth and gums are in good condition. Tell your dentist that you're planning to have aligner treatment so they can check for any potential problems.

Why does this matter? Straight My Teeth want to make sure that your teeth and gums are healthy and ready to start aligner treatment. If you’ve got any cavities or extractions that need taking care of, any sign of gum disease, or a broken or chipped tooth, you should get that all sorted before organising your aligners.

Not all mail-order aligner companies complete such stringent checks before you start your treatment. It might seem like a pain, but actually it ensures you'll get the best results possible and not damage your teeth and gums by having aligners.

If you have gum disease, for instance, then trying to straighten your teeth could worsen your gum disease or even cause your teeth to become loose.

Other criteria for Straight My Teeth treatment include:

  • You're aged 14 or over
  • All the teeth being straightened are natural (no veneers, crowns, bridges or implants)

If it turns out you're not a good candidate, don't give up on clear aligners yet! You may still be eligible for Invisalign treatment, which is able to treat a much wider range of bite problems thanks the company's more advanced technology and processes.

You can check your eligibility for Invisalign aligners online or find your nearest Invisalign provider to discuss your options.

Impressions or scans

Once you know you’re eligible for aligners, the next step is for Straight My Teeth to assess your teeth in more detail. There are two ways you can do this.

If you live near Ashford in Southeast London, close to Heathrow Airport, you can visit Straight My Teeth's Smile Studio for 3D scans carried out by their resident dentist. This consultation is free, but of course it may not be very convenient if you live in another part of the country.

Say cheese! Your kit includes cheek retractors to help you take clear ‘before' photos

The alternative is to order a Dream Smile Box impression kit, which costs £89. In it, you get everything you need to take dental impressions at home. You need to make two sets of impressions and they give you all the materials needed. Once done, you return everything in the postage paid box that comes with the kit.

Don’t worry if you make a mistake with the impressions or the company can’t work with them. You can request a second kit for half the price, and this gets refunded if you go ahead with your course of aligners.

Straight My Teeth's 100% money back guarantee means that if their orthodontists decide you're not a good candidate for their treatment, they will refund the full cost of your impression kit and any package you have signed up for. So, there's really nothing to lose by giving it a try if you're interested.

Treatment Plan

To understand the results you can achieve with Straight My Teeth, before and after images are sent to you in a smile simulation. This shows you what your teeth will look like afterwards and how long it should take to achieve the results.

This is the point where you commit and make payment. You’re also asked to sign a Consent to Treat and a Medical History form, and might need to upload your dental records, too.

Time to align

Your aligners should arrive in the post a couple of weeks after you give the go-ahead for your treatment. You need to wear them for 20-22 hours every day and only remove them for eating, drinking anything except water, and cleaning your teeth, unless you go for the NightOnly option.

The plan you get will give you exact details, but generally you change your aligner every two weeks. You might feel a little uncomfortable the first few days after each switch but that’s normal as your teeth move into their new position.

Refinements and retainers

Nine to twelve months is the average treatment time, and some plans last for up to 14 months. The price will be the same regardless, and you’ll come out with lovely straight teeth. To make sure you don’t lose your hard work, you need to wear a teeth retainer to keep your teeth in place following treatment.

Straight My Teeth treatment includes one set of retainers for free, but the usual price is £99. Wear them as prescribed by your assigned dentist or orthodontist, and your teeth should stay right where they are.

If there’s something you’re not happy with or you want some tweaks to your new smile, you can request a refinement plan. This will involve taking new impressions so you can have some more aligners sent out.

How much does Straight My Teeth cost?

Straight My Teeth costs £1,199 for a single course of clear aligner treatment, including a free teeth whitening kit and two sets of retainers. Their NightOnly option costs £1,299; a little more due to the extended treatment time, but still very affordable compared to the alternatives.

You can also go for the SmileAdvantage Plus option for £1,599, giving you nine sets of retainers. This package includes an impression kit, Smile Projection, clear aligners, and shipping throughout the UK.

Straight My Teeth prices are some of the cheapest around, making them very competitive compared to some of the bigger names on the market. They also sometimes have discounts available which can lower the cost even further – check their website to see what promotions they are currently running.

NewSmile is a Canadian company that brought its clear aligners to the UK market in 2022. NewSmile aligners are made from the clearest material and the company offers excellent service at the best price.

They don't have any physical locations, so you'll need to purchase an aligner kit to get started. One of their Impression Specialists will guide you through the process on a video call when you're ready.

NewSmile aligners are very affordable, costing just £1,395 (currently discounted to £1,295). But even better, this price includes whitening foam to use in your aligners, plus your first set of retainers!

Choose their daytime package for treatment in 4-6 months, or nighttime aligners for a more discreet treatment that takes 8-10 months. Both options come with 0% interest payment plans available.

Straight My Teeth reviews

To really understand if you should use Straight My Teeth, reviews are a great tool to give you loads of information. There are plenty of reviews on Trustpilot, such as these:

“Very good experience! Excellent customer service. Great product for the cost compared to other companies out there. Aligners came in the time expected. I started my treatment over 6 months ago and now on my last step. I am very pleased with the results. I would highly recommend Straight My Teeth.”

“I was recommended this company by a friend and I couldn’t be happier with the service. I am in week 4 of my treatment and, so far, am delighted with my treatment. I can already feel the difference. Would have been happier if I knew about this wonderful place earlier.”

Overall, Straight My Teeth's reviews on Trustpilot are 97% positive and they have a 4.5-star rating, at the time of writing. A lot of these are from people who have just started their treatment or are part way through it, but then again the company is so new that not that many people will have completely finished their treatment yet.

“The company is legit… I don't know why their price is so cheap”

In the Straight My Teeth review video below, Jo takes us through her Straight My Teeth experience as she wears her 7th and 8th sets of aligners. She has had a fair amount of aching and pain during the process so far, especially in the few days after fitting a new set. However, these two most recent ones were not as bad as some others.

As Jo points out in her video, everyone's experience will be different. Other patients may only experience mild aching or sensitivity in their teeth for 1-2 days.

After giving an update on her progress, Jo shows her Straight My Teeth ‘before and after images' documenting how far her teeth have moved so far. Then she goes on to answer some questions she's received from other people interested in Straight My Teeth aligner treatment.

Other mail-order aligners such as the following are a little more expensive:

Prices correct at time of writing but may change at any time.

If you're considering at-home aligners because you don't have the funds for in-office treatment, it makes sense to find the most affordable option you can.

As far as we're concerned, the lower price of Straight My Teeth doesn't mean you're compromising on service or quality. In fact, they one of only a handful of brands that work with orthodontists – not just general dentists – to plan your care.

The only downside is that they only have one physical location so far, although they provide online support if you need help with your impressions.

The Straight My Teeth referral scheme is also a nice bonus if you have some friends that want to join you in getting straighter teeth. And don't forget to check their website for discount codes before you order.

Straight My Teeth vs NewSmile

If you're looking for an alternative at a lower cost, NewSmile is priced at just £1,295 which makes it an affordable and popular at-home clear aligner treatment option. You also have the option of making interest-free monthly payments of £107.92, making it much more affordable than traditional braces or Invisalign.

NewSmile retainers are made from Raintree Essix plastic – the clearest plastic available on the market. The retainers also work on multiple teeth at once, which is why they can allow a shorter treatment period, and an orthodontist oversees each patient's treatment.

Treatment with NewSmile requires 22 hours of wear per day and treatment typically lasts for around six months. You can also opt for the nighttime treatment option at £1,395 which includes the impression kit, treatment preview, aligners, retainers, and whitening.

Straight My Teeth vs Smile Direct Club

Smile Direct Club is one of the biggest names in home aligners. Their package costs £1,539, which is significantly more than the £1,199 you'll pay for Straight My Teeth. However, Smile Direct Club has seven permanent SmileShop locations around the UK, which is a plus if you'd like a 3D teeth scan but don't live near London.


When it comes to price, Straight My Teeth are way out ahead. Their prices are considerably cheaper than competitors and there’s no sign of compromise on customer service or the results you get. Plus, their NightOnly option gives you more flexibility when choosing what will suit you best.

Although they only have one Smile Studio at the moment, they are pretty new so have some time to expand. The team is happy to support you through the process of making your impressions at home, too, so it’s not as daunting as it first seems.

Straight My Teeth may be a new name in this market, but they are doing a positive job in keeping their customers happy. It's easy to get started on your journey to a straighter smile, just click here to visit Straight My Teeth's website and complete a short assessment or order your aligner package!

We recommend visiting a dentist for a general checkup before starting any at-home treatment. It’s important to deal with any untreated cavities or gum disease before wearing aligners. Plus, you could ask your dentist to assess your overall suitability for the treatment.


What were Straight My Teeth aligners, and why did they stop selling them?

Straight My Teeth aligners were a brand of clear aligners used for teeth straightening. Although their website is still active, they stopped selling aligner treatments for reasons specific to their company.

Are there any alternative brands or options available now that Straight My Teeth is no longer selling aligners?

Yes, there are other reputable brands and options available for clear aligner treatments. Our top pick is NewSmile aligners, they have both daytime options and nighttime aligner options.

Can I continue using my Straight My Teeth aligners even though they have stopped selling them?

While you may be able to continue using your existing Straight My Teeth aligners, it's important to understand that orthodontic treatment requires ongoing professional supervision and support.

Can I use other clear aligner brands to continue my treatment?

Yes, if you have been using Straight My Teeth aligners and they are no longer available, you have the option to explore other clear aligner brands. However, make sure you consult with your dentist first.
