Are you looking at ways to straighten teeth at home? Whether for financial reasons or because you'd rather avoid regular visits to a dentist right now, there is a way to do this in the form of home teeth straightening kits that use clear aligners.

On the surface, buying teeth aligners online seems like a good idea. They let you fix crooked teeth at home, avoid the ‘metal mouth' look, and save money vs. some in-office treatments.

And they have proven very effective for thousands of patients, not just in the UK but across the world. However, there are some important things to consider before you go ahead with any kind of teeth straightening at home.

Here we're going to look at the pros and cons of DIY teeth straightening kit options vs visiting a dentist for orthodontic treatment. We'll also review some of the biggest home aligner brands in the UK so you can decide which (if any) is right for you.

Looking for the best Teeth Straightening Kit? Here's our recommendation…

Smile White treats most alignment problems, thanks to in-person monitoring by a dentist. However, unlike other brands and treatments, you only have 3 in-office visits — the rest of your treatment is done at home. From mild adjustments to complex bite misalignment, these Aligners can help.

How can you get teeth aligners at home?

Home teeth straightening kits let you bypass dental visits

You can order teeth aligners online. Online teeth straightening kits have been available in the UK for several years, but the pandemic has increased demand for them. They offered people a way to straighten teeth at home while dentists were closed for long periods.

Clear aligners, or ‘invisible braces', are removable plastic trays made to fit over your teeth and apply pressure in specific places. You change to a new set of aligners at regular intervals during your treatment, and each one shifts your teeth a little further until they are properly aligned. The best known of these is the Invisalign system, which is administered by a dentist or orthodontist in-office.

Even now that most practices have re-opened, many patients are reluctant to make regular visits to what could be seen as a high-risk environment (but be assured that dentists are taking every precaution to keep their clinics safe).

How to straighten teeth at home

Different brands work in slightly different ways, but here are the basic steps for getting teeth aligners at home:

  1. You order an impression kit online (or visit a physical location to get a 3D scan taken).
  2. Using this kit, you make your own teeth impressions at home and post them to a lab.
  3. A dentist reviews your impressions (or scans) and determines whether you are eligible for treatment.
  4. If yes, you receive a treatment plan and a preview of how your smile will look after teeth straightening.
  5. You receive your full set of aligners in the post, with instructions on how long to wear each set.
  6. During your treatment, you check in online so your dentist can monitor progress against your treatment plan.
  7. Once treatment is complete, you wear retainers to keep your teeth in their new position.

You don't have any face-to-face contact with a dentist, which is one obvious drawback of this kind of treatment (unless, perhaps, you have a dental phobia). But this is also what makes the price so much cheaper than in-office alternatives. Ultimately, you'll have to decide what matters most to you.

Pros and cons of using a home teeth straightening kit in the UK

Teeth aligners offer many benefits over traditional fixed metal or clear braces:

  • They are practically invisible
  • They can be removed for 2-4 hours per day
  • You can clean your teeth as normal
  • There are no restrictions on what you can eat (as long as you remove your aligners first)

On the downside, wearing aligners does require some willpower. It can be inconvenient having to remove them every time you eat or drink anything except water – and brush your teeth afterwards. And the fact that they are removable means they can be lost. No risk of that with metal braces!

All of these things apply whether you straighten your teeth at home or visit a dentist for your treatment.

Are clear aligners as effective as traditional braces?

Well, in-office brands like Invisalign aligners can treat around 90% of orthodontic cases. This makes them a very effective alternative to traditional braces for the majority of people. But when it comes to teeth straightening at home, online aligner kits are only suitable for mild to moderate cases.

There are no visits to a dentist with at-home options

You can get a good idea of whether you're eligible with a quick online assessment. But you won't know for sure until a dentist has assessed your dental impressions or scans.

Other things that differ when you straighten teeth at home include:

  • You won't see a dentist in-person (which you may see as a good or bad thing!)
  • You'll check in regularly using an app rather than visiting a dental practice.
  • You have to take your own teeth impressions at home (unless you choose a brand with physical locations).
  • If you have any problems, your first port of call will be a customer service team.
  • You'll pay much less for an at-home teeth straightening kit.

While researching brands, be sure to check not just their ‘before and after' results, but also reviews of their customer care. If you get stuck taking your teeth impressions or your aligners don't seem to fit properly, it's good to know you can easily get in touch with someone for assistance.

Is it safe to straighten teeth at home?

Overall, yes, it is safe to use a home teeth straightening kit with remote supervision from a dentist or orthodontist. However, there are some caveats to this.

Firstly, we recommend that you have a dental checkup before beginning to straighten teeth at home. This is because if you have any untreated dental caries or gum disease, you probably shouldn't be wearing aligners. Your dentist can help you with these problems before you proceed with aligner therapy.

Secondly, even with the best hands-on supervision, teeth don't always move as expected during orthodontic treatment. And while the technology used for remote monitoring is very sophisticated, it's not quite the same as having a dentist examining your teeth face-to-face.

The main risk here is that you will get to the end of your treatment and find your teeth aren't still quite as you wanted. In this case, it should be possible to make some extra adjustments, but you may be asked to pay extra for these.

If you'd prefer to have the assurance of in-person treatment, consider having Invisalign treatment instead. It may not cost much more than online aligners, especially if you only need mild tooth movement, and they have a large network of dentists and orthodontists around the UK.

NewSmile braces
NewSmile is affordable and effective!

By this point, you have probably heard of NewSmile, and perhaps a few other brands offering teeth aligners online in the UK including the following:

NewSmile offers the clearest aligners available, a short treatment time in as little as 4 months, and they are known for their stellar customer service. You can also opt for nighttime-only aligners, plus you get a teeth whitening treatment with your package. Check out our NewSmile review to find out more.

Smile Direct Club is the biggest and has been operating for some time in the US. However, their frustrating customer service and questionable business practices mean they aren't top of our recommended brands. You can read some Smile Direct Club reviews to learn more.

Several other brands like Franksmile and Your Smile Direct have run into financial difficulties recently, leaving many customers stranded halfway through their treatment.

How to straighten teeth without braces at home

If you simply want to avoid conventional fixed braces then removable braces are a great alternative. They are very hard to spot, and there isn't the same risk of long-term damage to your teeth from decalcification.

You may have seen people trying to close gaps in teeth using elastic bands, or using other DIY teeth straightening methods. We don't advise trying anything without the supervision of a dentist or orthodontist, as you risk doing some serious damage to your teeth.

With the entire treatment course from Straight My Teeth costing just £999 (with monthly finance available), teeth straightening at home can be really affordable. You also don't have to visit a dental practice, which can be helpful if you have a dental phobia or feel unsafe being in that setting right now because of COVID-19.


Now you know how to straighten your teeth at home safely – and the things to consider before embarking on this type of treatment. Here's a quick summary of the options we've mentioned:
