How to Straighten Teeth: Teeth Straightening Costs & Options in the UK

Teeth straightening is a common dental procedure for people who are unhappy with the appearance of their teeth. It may be recommended by a dentist for medical reasons, or it may be a personal choice for cosmetic reasons. Either way, modern dentistry makes it possible to correct even severely misaligned bites.

The benefits of straighter teeth

You might think that teeth straightening is all about aesthetics, but there are actually some valid medical reasons for correcting misaligned teeth. 

Crooked teeth can cause various problems, depending on the severity of the misalignment:

  • Speech problems
  • Difficulty eating
  • Muscle strains
  • Risk of damage to other teeth
  • Problems maintaining good oral health

That last point can affect anyone with even slightly crooked teeth; if the teeth aren't correctly aligned, it's harder to clean them properly. This, in turn, means a greater likelihood of plaque buildup leading to tooth decay. A thorough oral health regime can help manage this risk.

Ask a dentist: Does teeth straightening only correct cosmetic flaws?

While straightening your teeth can correct cosmetic problems and improve your smile’s appearance, it has even more benefits for your oral health. When a patient has crooked teeth, they often experience problems that interfere with their daily lives.

For example, crooked teeth can cause difficulty chewing or talking, but this issue can even contribute to jaw problems and damage to nearby teeth. Additionally, crooked teeth are more difficult to clean and care for, which means you could be more susceptible to problems like cavities and gum disease.

Of course, appearance is also an important factor for many people, as this BBC article shows. Those who aren't blessed with a perfect smile can be self-conscious about their teeth, and may opt to get them straightened even if there isn't a medical need to do so.

We have a separate guide which covers the different types of malocclusion (bite misalignment). Here you can read about which malocclusions pose a medical risk, what causes crooked teeth in the first place, and possible treatments.

Teeth straightening options in the UK

Metal braces might be the first thing that comes to mind when you think about getting a straighter smile, but dentists can use different kinds of braces, including clear braces and removable aligners, to straighten teeth. There are also ways to straighten teeth without braces.

Ways to straighten teeth include:

We'll cover each of these in more detail in just a moment, but the video below contains a brief overview of some of these teeth straightening options:

If you want the perfect smile, there are a number of ways to straighten your teeth. Top cosmetic dentist Dr Adam Thorne guides us through different types of braces and aligners and their pros and cons. To book an appointment with Dr Thorne, visit his profile here:

Teeth straightening surgery may be required to treat certain malocclusions such as a severe open bite, underbite, overbite or crossbite. This is usually done in conjunction with orthodontic work.

Can teeth be straightened at any age?

The best time to straighten teeth is in the teenage years, before the jaw bone and teeth roots are fully developed. This is why it's important to take your child for regular dental checkups. If your dentist identifies a need for orthodontic treatment, he or she will plan this for the optimal time according to your child's development.

That said, teeth straightening for adults is still very effective. Our teeth can change position as we get older, usually becoming more crooked, so teeth that used to be quite straight may start to bother you later in life. Or, perhaps you have always had wonky teeth but just never got braces as a child.

Whatever your age, if you're unhappy with the way your teeth look then there are various ways to fix your smile. Did you know there's a way to see what you'd look like with straighter teeth, and it only takes two minutes to find out?

Different types of braces for straightening teeth

First, let's look at the different kinds of braces that are used for teeth straightening for adults, teens and children. You can read more about each of these by following the links in each section.

Metal braces

A common option for teeth straightening in the UK

This is usually the cheapest way to straighten teeth with braces, and metal braces are the only way to get teeth straightening on the NHS.

Metal brackets are attached to the teeth and a wire is threaded through them to pull the teeth into position. Small elastic bands hold the wire in place – you can usually choose the colour of your elastics to add a touch of style to your braces. Adjustments take place every month or so.

Another option is self-ligating braces, which don't need elastics; these ‘auto-adjust' so don't require such frequent adjustments. If your teeth are particularly crowded, you might need to have orthodontic spacers placed to create more room ahead of your braces being fitted.

If you are just looking for cheap braces, you may want to see what your options are before deciding on metal braces.

Clear braces

People who want a less noticeable option may consider clear braces to straighten their teeth. These work in the same way as metal braces but use ceramic materials which are clear or tooth-coloured, making them much less obvious.

Invisible braces

Invisalign clear aligners are a popular option when it comes to teeth straightening for adults who don't want people to know they're wearing braces. Similarly, children who are worried about bullying in school might prefer this style.

Invisible aligners are very popular for teeth straightening

These removable, clear aligners straighten teeth by applying pressure in just the right places. You'll get a new set every two weeks or so, with appointments every four to six weeks to check your progress.

Invisible braces work well for mild to moderate correction and can be a good, quick option – particularly if you just want to straighten your front teeth. To see whether you're a suitable candidate for teeth straightening with clear aligner braces (90% of people are), take Invisalign's free online Smile Assessment. It only takes two minutes to get your answer!

The Invisalign system is available from large network of UK dentists and orthodontists so your nearest one shouldn't be too far away. You can search online to find Invisalign providers near you and book an appointment online.

Although Invisalign aligners are the biggest name in the clear aligner market, and arguably the best, there are plenty of other options out there. These include at-home aligner treatments, which we cover in more detail below. You can read about more Invisalign alternatives in our separate guide.

Lingual braces

Also known as ‘hidden braces', lingual braces are perhaps the least noticeable type of brace because they are fixed to the back of the teeth, next to the tongue. This means they are only visible when you open your mouth very wide.

However, they come at a price; they are the most expensive type of braces available, especially if you get a custom-made brand like Incognito braces. You can see more detailed costs in the table further down.

If you're concerned about aesthetics but still want a cheaper teeth straightening option, invisible braces might be the best solution.

How to straighten teeth without braces

Braces are the most effective way to straighten crooked teeth, and clear aligners are a popular option for people who want to avoid the look of traditional metal braces. Still, there are some alternative ways to straighten teeth that may work for you, depending on your circumstances.

Using a retainer for teeth straightening

Clear or metal retainers can achieve some straightening without braces

Retainers are primarily used to retain the position of teeth following orthodontic work, hence the name. However, it is possible to achieve minor teeth straightening using a retainer or a device like the Inman Aligner.

Both clear retainers and metal retainers can straighten teeth to some degree, but the results are far more limited than with braces. Clear retainers might look the same as clear aligner braces, but they work differently.

If you're looking for an affordable teeth straightening option for minor correction, especially after wearing braces in the past, then your dentist may offer a retainer. This can be adjusted slightly as treatment proceeds, but scope is far more limited than with braces.

Where greater movement is required, you'll need to consider the other options. You can read more about the different types of retainers and costs in this guide.

Can veneers straighten crooked teeth?

Although veneers can't change the position of teeth, they can make them look straighter. To achieve this, dentists drill down part of the crooked teeth and then fit a porcelain veneer over the top. The result is that the teeth look better aligned, even if underneath the original teeth are still crooked. This technique only works on mild cases.

Veneers can also be used to close small gaps between teeth. Read more about the process in our complete guide to teeth veneers.

Veneers can offer cheap teeth straightening prices compared to braces, depending on how many teeth need to be treated. This is also a much quicker treatment option, usually requiring just two appointments.

However, keep in mind that veneers are not a permanent fix. After 5-10 years they will need to be replaced, either with new veneers or with crowns. They often cause irreparable damage to the teeth underneath because of the enamel removal, so consider the long-term implications before going ahead.

Contouring and bonding

In certain cases it's possible to do less drastic cosmetic work by filing down parts of the teeth (e.g. rough edges and parts that protrude) and building other areas up with composite material. As with veneers, this can make the teeth appear straighter without having to move their position using braces.

Teeth straightening at home

It is possible to straighten your teeth without visiting a dentist at all! People looking for cheap teeth straightening options or who have a dental phobia may benefit from an at-home solution. And, no we don't mean homemade fake braces, there are safe and effective ways to straighten your teeth from home without resorting to potentially harmful options.

Teeth straightening kits

In recent years, at-home solutions from “teledentistry” companies have become quite popular in the UK. Smile Direct Club is one such company which launched in the UK in July 2019 having had huge success in the USA. Other brands like Your Smile Direct and Straight Teeth Direct offer a similar clear aligner service.

These clear aligners are generally cheaper than getting braces at the dentist because everything is done by post. You're therefore not paying for the business overheads of a dental clinic.

You'll use a kit to create your own teeth impressions at home, or you may have the option to visit a local clinic (not all brands offer this option). The company then creates a treatment plan and sends your clear aligners in the post.

These kits can be effective for mild cases, but they carry some risks. The main problem is that you're not meeting face-to-face with a dental professional who is a specialist in straightening teeth. Sending photos and impressions – even having a video call – isn't the same as a proper consultation to discuss your treatment.

Home straightening kits also often rely on you accurately capturing your own dental impressions. If anything goes wrong with this process, your aligners may not fit properly and the whole treatment may be ineffective.

Despite all of this, teeth straightening kits can deliver good cosmetic results – you don't have to search far online to find plenty of happy customers.

If this is something you're interested in, we recommend a brand of clear aligners called Straight My Teeth. Their aligners use patented technology and they score very well in terms of customer satisfaction. Plus, they only cost £799 which is cheaper than all the other big brands available in the UK.

You can read more in our full review of Straight My Teeth, or visit their website to take a quick eligibility test which will tell you if this is a suitable treatment for you.

Using mewing to straighten teeth naturally

Another teeth straightening technique you might have heard of is ‘mewing'. This basically involves consciously pushing the tongue against the roof of the mouth until it becomes the natural resting position.

We don't recommend trying mewing to straighten teeth naturally, since this isn't a proven benefit. It may help expand the palate when done correctly, and this can reduce problems with overcrowding. But if your teeth are already misaligned, chances are you need a dental appliance to straighten them.

It's better to discuss your concerns with an experienced dentist who can advise you on the best treatment options.

How much does teeth straightening cost in the UK?

Teeth straightening in the UK costs from £1,000 to £10,000 with braces and from £50 to £1,000 per tooth without braces. See the table below for a better idea of cost using each method we've mentioned.




Metal braces

You can see that teeth straightening costs vary greatly depending on the method used. The cheapest is not necessarily the best, so consider your options carefully – and decide whether you need treatment at all – before parting with any money.

If you're considering teeth straightening with Invisalign treatment, search for your nearest provider online and book a consultation. Then, you can receive a precise treatment plan and price for your teeth straightening.

What's the cheapest way to straighten teeth?

As you've seen above, at-home aligner kits are often the cheapest way to straighten teeth. They are only suitable for mild to moderate cases, but it's easy to check whether you're a good candidate. Simply take this free online assessment from Straight My Teeth, whose aligners cost just £799 for a complete course of treatment.

Retainers can offer cheaper teeth straightening prices, but they only work in very mild cases. For more significant teeth straightening, most people will need braces, in which case traditional metal braces or at-home clear aligners are usually most affordable.

Lingual braces have good aesthetics but are not the cheapest way to straighten teeth

Invisalign treatment can be comparable in price to metal braces, especially if you don't need a long treatment course. For instance, Invisalign Express costs from £1,500 in the UK and comes with the big benefit of in-person monitoring with your dentist or orthodontist.

When looking for teeth straightening near you, it's a good idea to check prices from two or three dentists. Teeth straightening prices can vary quite considerably from one to another, so you may be able to save money that way.

You might also want to check out your dental finance options. There are ways to make teeth straightening prices more affordable, for example by spreading payments with a dental loan or payment plan.

Can you get teeth straightening on the NHS?

Children whose treatment has been deemed medically necessary can get free teeth straightening in the UK on the NHS. This covers metal braces and retainers, plus any surgery (if required). Our guide to braces for kids has more information about the eligibility criteria for children's teeth straightening on the NHS.

Teeth straightening for adults is not provided by the NHS, except in extreme cases. It's most likely you'll have to pay for your treatment privately, but there are ways to make teeth straightening costs in the UK more affordable.


When deciding how to straighten your teeth – whether it's a significant correction or just mild adjustment you need – there are several different options to consider.

Braces are the most common treatment for teeth straightening, whether metal or ceramic brackets fixed to the teeth, or clear aligners that straighten teeth without it being so obvious. If you're considering invisible aligner braces, don't forget to check whether you're a suitable candidate with an Invisalign Smile Assessment.

You can also search for your nearest Invisalign provider and book an appointment to discuss your treatment further. They'll be able to give you a detailed treatment plan as well as a fixed cost for your treatment.

There are several brands of at-home clear aligners in the UK. These are becoming increasingly popular because they cost less than in-office braces, and you can complete your treatment entirely from home. They aren't suitable for everyone, but you can take a free online assessment from Straight My Teeth – our recommended brand which costs just £799 for an entire treatment course.

Veneers may be appealing because they are so quick and convenient. Remember they are not truly straightening the teeth – just masking the problem. You need to consider the longer-term cost and inconvenience of replacing them when they fail.

Whatever you decide, we hope this article has helped you understand more about your teeth straightening options in the UK.


How long do braces take to straighten teeth?

We can say that teeth straightening with braces takes 12-18 months on average, but it can be as little as 3-6 months in mild cases. More severe cases can take two years or more.

The type of braces you choose for your treatment will also affect your treatment time to some degree. It's natural to want to know how long braces will take to straighten your teeth before you begin treatment, and your dentist should be able to give you a pretty good idea when you have your consultation.

Can you straighten teeth without braces?

Yes, there are some options for teeth straightening without braces. Clear aligners are very popular – these removable trays fit over the teeth to align them. Veneers can make teeth appear straighter.

If you want to avoid fixed braces, your dentist can explain the best solution according to your age and the condition of your teeth.

Can you use an old retainer to straighten teeth?

We don't recommend it! It's understandable that you want to save money, but using an old retainer may damage your teeth if they have moved out of position since you last wore it. 

Retainers are designed to keep your teeth in place after braces. Follow your dentist's instructions to keep your teeth straight following orthodontic work.

Can I use a night retainer to straighten teeth?

You may only need to wear a retainer at night to keep your teeth straight after braces, but aligners usually need to be worn for 20-22 hours a day for effective straightening. If your teeth aren't under constant pressure to move, they'll start slipping back to their old position during the downtime. 

That said, some at-home aligner brands do offer a nighttime only treatment option. Since you're only wearing your aligners for 10 hours per day, your treatment time will be quite a bit longer.

Unless you really don't want to wear aligners during the day, the regular treatment option is best as it works most efficiently. Remember, Invisalign aligners and other clear aligner braces are practically invisible, so you needn't feel self-conscious about wearing them. Check here to see whether you're eligible for invisible braces and understand more about your treatment options.

Can teeth straighten themselves?

It is only possible for teeth to straighten themselves while they are still erupting. The first few permanent teeth might come in crooked and then correct themselves as the other teeth erupt. In adults, though, teeth are likely to become more crooked over time, not straighter.

Can you get your teeth surgically straightened?

Jaw surgery may be carried out in addition to treatment with braces. This doesn't surgically straighten individual teeth but it does re-align the jaw so that the teeth can come together properly.

Why is straightening teeth important?

Most people want straighter teeth for aesthetic reasons, but there are also some health benefits. Crooked teeth are harder to clean, and may lead to oral health problems like decay and gum disease. So, by straightening your teeth you are giving yourself a better chance of avoiding tooth decay and other problems in the future.
