TL;DR Lingual braces, fixed behind the teeth so they stay hidden, cost roughly £2,000 to £10,000 or more privately in the UK, with most full-mouth cases between £4,000 and £8,000. They are not funded by the NHS at any age. Prices are set by individual practices, so a consultation quote is the only reliable figure for your own treatment.
Lingual braces are the most discreet fixed-brace option available in the UK, worn entirely behind the teeth where nobody can see them. That invisibility comes at a premium, and because pricing sits entirely in the private market, the figures can feel confusing. This guide sets out realistic UK price ranges for 2026, explains what drives the cost, and shows how lingual braces compare with the other ways to straighten your teeth.
What are lingual braces?
Lingual braces are fixed braces bonded to the back, tongue-facing surface of your teeth rather than the front. Small brackets are attached to each tooth with dental adhesive, and a wire connects them to apply gentle pressure that moves the teeth into position, exactly like conventional braces but hidden from view [9]. The mechanism is identical to any fixed brace: brackets, a connecting wire, and regular adjustments over time [1].
The word "lingual" simply means "towards the tongue". Because the brackets face inwards, most people looking at you cannot tell you are wearing braces at all. That is the single reason patients choose lingual over cheaper, visible alternatives. The British Orthodontic Society describes them as "concealed on the inside of the teeth" and "most often worn by adult private patients who want their teeth straightened but don't want to be seen in braces" [9].
You may also see lingual braces marketed as "hidden braces", "incognito braces" or "behind-the-teeth braces". These all describe the same category of treatment, though "Incognito" is also the name of one specific branded system rather than a generic term for the technique.
How much do lingual braces cost in the UK?
Lingual braces typically cost between £2,000 and £10,000 or more in the UK, with most full-mouth treatments falling between £4,000 and £8,000. No NHS body, regulator or official source publishes a price schedule for lingual braces, because they are an entirely private, cosmetic treatment. Every figure in this guide is a market estimate triangulated from UK private clinic price lists surveyed in July 2026, not an official rate.
The price you are quoted depends mainly on two things: how complex your case is, and which lingual system your orthodontist uses. As a rough guide:
| Case type | Typical UK private price (estimate) |
|---|---|
| Limited treatment (front teeth only, minor crowding) | £2,000 to £4,000 |
| Full treatment, standard or semi-custom system | £4,000 to £6,500 |
| Full treatment, fully customised system | £5,000 to £10,000 or more |
Single-arch treatment, straightening just the top or bottom teeth, costs less than treating both arches. There is no official ratio, but UK providers commonly price a single arch at around 50 to 65 per cent of the full dual-arch fee. Some patients reduce the cost by combining a hidden lingual brace on the more visible upper teeth with a conventional or tooth-coloured brace on the lower teeth [9].
Because these are private prices set practice by practice, treat every range here as a starting point for budgeting, not a quote. The only reliable figure for your own teeth comes from an in-person consultation with a specialist orthodontist. For a wider view of what it costs to straighten teeth by every method, see our guide to the cost of teeth straightening in the UK.
Lingual braces prices by system
Not all lingual braces are the same. The largest single cost driver is whether the brackets are standardised, made in fixed sizes, or fully customised, individually designed and manufactured for your teeth. Fully customised systems cost the most because each bracket, and often the wire, is designed from a 3D scan of your teeth using CAD software, then manufactured to match that specific tooth's anatomy [12].
| System type | What it is | Price indication |
|---|---|---|
| Standardised lingual brackets | Off-the-shelf brackets in fixed sizes, best for milder cases | Lower end, around £2,000 to £3,000 |
| Short-term or limited (front-teeth systems) | Semi-custom brackets for front-teeth-only cosmetic cases | £2,000 to £4,000 |
| Fully customised systems | Brackets individually designed and made per tooth | £5,000 to £10,000 or more |
Fully customised systems have been sold under brand names including WIN, Harmony and Incognito. Because manufacturers periodically update, rename or withdraw specific product lines, do not assume any particular brand is available. Always confirm which system a practice actually uses at your consultation, and ask what makes it suitable for your case, rather than choosing on brand name alone.
There is also a genuine clinical difference between systems that can affect treatment time. In one comparative clinical trial of two fully customised lingual systems, the WIN appliance completed treatment significantly faster than the Incognito appliance for cases of similar complexity [13]. This is a useful reminder that the specific system matters, not just the "lingual" label.
How lingual braces compare with other options
Lingual braces are the most expensive mainstream way to straighten teeth in the UK, mainly because of the custom manufacturing and the smaller pool of trained providers. The table below sets them alongside the other common private options so you can see where they sit. These are all private estimates for dual-arch treatment; the NHS position is covered in the next section.
| Treatment | Typical UK private range (dual arch) | Visibility |
|---|---|---|
| Metal fixed braces | £1,800 to £5,000 | Visible |
| Ceramic (tooth-coloured) fixed braces | £2,500 to £6,500 | Low visibility |
| Clear aligners (in-clinic, e.g. Invisalign) | £1,500 to £5,500 | Nearly invisible, removable |
| Lingual braces | £2,000 to £10,000 or more | Invisible, fixed |
Clear aligners are the closest alternative on discretion and usually cost less, but they work differently. Aligners are removable and best suited to mild-to-moderate cases that depend on the patient wearing them for 20 to 22 hours a day, while lingual braces are fixed and can offer greater three-dimensional control over a wider range of problems [9]. If you are weighing these two up, our guides to Invisalign costs and Invisalign versus braces go into more detail, and our overview of teeth-straightening options compares every route side by side.
Can you get lingual braces on the NHS?
No. Lingual braces are not available on the NHS at any age. NHS orthodontic treatment uses standard fixed metal braces only, and no lingual, ceramic or clear-aligner option is offered [1]. Anyone who wants hidden braces will need to pay privately.
NHS orthodontics is also tightly rationed. Treatment is free for people under the age of 18 who have a clear clinical need, assessed using the Index of Orthodontic Treatment Need (IOTN) [2]. Under this system, treatment is available for the more severe grades (4 and 5), while borderline grade 3 cases are judged individually. For adults, NHS orthodontic treatment "is not usually available", and most adults who want their teeth straightened have private treatment [2]. Even in the rare cases where an adult does qualify on genuine health grounds, only a standard NHS metal brace is provided, never a lingual one.
For the small number of eligible adult NHS cases in England, orthodontic treatment falls under Band 3, which costs £332.10 from 1 April 2026 [3]. NHS dental charges differ in Scotland, Wales and Northern Ireland, but the key point is the same across all four nations: lingual braces are a private treatment everywhere. If your child may qualify for free treatment, our guide to NHS braces for children explains eligibility in full.
How lingual braces work: the treatment process
Lingual treatment follows a clear sequence, with the custom manufacturing step being the main difference from ordinary braces.
- Consultation and assessment. A specialist orthodontist examines your teeth in person, takes X-rays and discusses whether lingual braces suit your case. This in-person assessment is essential and cannot be replaced by a remote or postal service [6].
- Scanning and design. Digital or physical impressions of your teeth are taken. For fully customised systems, these are turned into a 3D digital model, and the bespoke bracket for each tooth is designed in CAD software [12].
- Manufacturing. The custom brackets, and often the wires, are then manufactured to fit the back surface of each individual tooth. This lab stage is why customised systems cost more and why there is usually a wait of several weeks between the scan and the fitting appointment.
- Fitting. The brackets are bonded to the tongue-facing surface of your teeth. For full-mouth cases this is sometimes spread across two visits because of the precision involved.
- Adjustments. You return regularly so the orthodontist can adjust the wire. NHS fixed braces are typically adjusted every 6 to 8 weeks, and lingual appointments follow a similar rhythm, though each visit can take a little longer because the back of the teeth is harder to reach [1].
- Retention. Once the braces come off, you wear retainers to hold your teeth in their new position and prevent relapse, just as with any brace [1]. Budget for these separately, since retainers are an ongoing part of keeping your teeth straight after treatment.
How long does lingual braces treatment take?
There is no single official figure for lingual treatment time, but it is broadly similar to, or slightly longer than, conventional fixed braces for a comparable case. NHS fixed braces usually stay on for one to two years [1], and lingual treatment falls in a similar window, with UK clinics commonly quoting 12 to 18 months for a typical full-mouth case and longer for complex ones.
Duration also varies between lingual systems, not just between patients. As noted above, a comparative trial found one fully customised system completed treatment significantly faster than another for similar cases [13]. Simple, front-teeth-only cosmetic cases can be much quicker, but they only address the visible front teeth, not your full bite.
Pros and cons of lingual braces
Lingual braces have a clear headline benefit and several real trade-offs. Weighing them honestly is the best way to decide whether the premium is worth it for you.
Advantages
- Genuinely invisible. The brackets sit behind your teeth, so the treatment is hidden even in close-up photos. This is the main reason patients choose them [9].
- Marks stay hidden. Any decalcification or white marks that can occur during brace treatment form on the tongue-facing surface rather than the visible front of the tooth. The British Orthodontic Society notes lingual braces "are less likely to mark teeth than standard braces" [9].
- Full fixed-brace control. As a fixed appliance, lingual braces can treat a wider range of problems than removable aligners and do not rely on you remembering to wear them [9].
Disadvantages
- Higher cost. They are the most expensive mainstream option, as the pricing above shows.
- Temporary speech changes. Because the brackets sit near the tongue, peer-reviewed research finds lingual braces cause noticeable, temporary effects on speech in the first weeks, more so than front braces [10]. Most people adapt within a few weeks.
- Tongue soreness. Tongue irritation is significantly higher in the first 24 hours after fitting, then settles over the following weeks as the tongue adjusts [11].
- Harder to clean. The tongue-facing surface is more difficult to see and reach, and good cleaning takes real motivation to avoid gum inflammation and plaque build-up [14].
- Fewer providers. Only about 10 per cent of the UK's registered orthodontic specialists offer the lingual technique, so you may need to travel to find an experienced provider [9].
Are you a suitable candidate for lingual braces?
Lingual braces can treat a wide range of cases, including complex adult cases, but suitability is best confirmed at a specialist consultation. Fixed appliances, including lingual, give the orthodontist greater three-dimensional control than removable aligners and can handle more challenging tooth movements [9].
Contrary to some marketing claims, lingual braces are not automatically unsuitable for a deep bite. In one matched comparative study of adults, lingual appliances achieved favourable lower-incisor movement without unwanted tipping, and the authors concluded lingual treatment "is a better option in adult cases where intrusion of lower incisors without labial tipping is desired" [15]. As with any appliance, the right choice depends on your individual bite and tooth anatomy, which only an in-person assessment can determine. The safest approach is to treat candidacy as something a specialist confirms for you, rather than ruling yourself in or out from a website.
Paying for lingual braces
Because lingual braces are a significant private cost, most patients spread the fee over time rather than paying upfront. Common arrangements in the UK include:
- In-house payment plans. Many practices spread the cost across the treatment period in monthly instalments, often interest-free [7].
- Third-party finance. Practices can arrange finance through a healthcare lender, where you repay the lender directly under a regulated credit agreement.
- 0 per cent and longer-term finance. Interest-free deals are commonly offered over a fixed period, with interest applying on longer terms.
Any dental practice that offers or arranges credit must be authorised or registered with the Financial Conduct Authority (FCA) [8]. This gives you consumer protection, so it is reasonable to ask a practice how their finance is regulated and exactly what you will repay before you commit. Confirm too whether the quoted fee includes retainers and every adjustment appointment, since these are sometimes bundled into an all-in fee and sometimes charged separately.
Choosing a lingual orthodontist safely
Lingual braces must be fitted in person by a registered professional, which makes them structurally different from mail-order aligner products. Choosing a suitably qualified orthodontist is the most important safety step you can take.
Check that your clinician is registered with the General Dental Council. A dentist can use a specialist title such as "specialist orthodontist" only if they are on the GDC's specialist list [4], and members of the public can verify any dentist's registration and specialist status directly on the GDC's online register [5]. Because lingual work is niche even among specialists, it is fair to ask a prospective orthodontist about their specific lingual training and how many lingual cases they treat.
Be wary of any service that offers to straighten teeth without an in-person examination. The GDC is clear that "there is currently no effective substitute for a physical, clinical examination" for orthodontic treatment [6], and warns that "without an in-person checkup, the dentist might not spot" problems that could make treatment unsafe [16]. The CQC similarly requires direct-to-consumer aligner providers to have a GDC-registered dentist assess and oversee treatment, because home impression kits "may not be accurate enough for diagnosis" [17]. Lingual braces, by their nature, always involve the in-person, specialist-led care that regulators say patients should prioritise.

Frequently asked questions
Are lingual braces worth it?
Lingual braces offer genuine invisibility, and any tooth marking during treatment stays on the hidden back surface rather than the visible front [9]. Whether the premium is worth it depends on how much discretion matters to you against the higher cost, the smaller pool of providers, and a short adjustment period. For image-conscious adults, many find the trade-off worthwhile.
Do lingual braces hurt or affect your speech?
Temporarily, yes. Peer-reviewed research confirms lingual brackets cause noticeable, short-term effects on speech in the first weeks because they sit near the tongue, more so than front-mounted braces [10]. Tongue soreness is also higher in the first 24 hours, then eases as the tongue adapts [11]. Most people adjust within a few weeks.
Lingual braces or Invisalign, which is cheaper?
Clear aligners such as Invisalign are usually cheaper, typically £1,500 to £5,500 in-clinic, while lingual braces run £2,000 to £10,000 or more. They also work differently: lingual braces are fixed and suit a wider range of cases, whereas aligners are removable and depend on you wearing them for most of the day [9].
Can you get lingual braces on the NHS?
No. NHS orthodontic treatment uses standard fixed metal braces only, and lingual braces are private at any age [1]. Free NHS treatment is limited to under-18s with a clear clinical need under the IOTN system, and adults very rarely qualify for any NHS orthodontics [2]. Anyone wanting hidden braces pays privately.
How long do lingual braces take?
There is no single official figure, but treatment is broadly similar to conventional fixed braces, which usually stay on for one to two years [1]. UK clinics commonly quote 12 to 18 months for a full-mouth case, longer for complex ones. Treatment time also varies between different lingual systems, not just between patients [13].
How do you clean lingual braces?
Cleaning is harder than with front-facing braces because the brackets sit on the tongue-facing surface, which is difficult to see and reach [14]. Standard fixed-brace hygiene applies: brush with fluoride toothpaste after meals and before bed, use interdental brushes daily, and avoid sugary, hard or sticky foods that raise plaque risk or could damage the brace [1].
Are lingual braces suitable for everyone?
Not automatically, though they treat a wide range of cases in experienced hands, including some complex adult cases and certain deep bites [15]. Only around 10 per cent of UK orthodontic specialists offer the technique [9], so experience with your specific case varies. An in-person specialist assessment, never a remote one, is the only way to confirm you are a suitable candidate.
Conclusion
Lingual braces are the most discreet way to straighten your teeth in the UK, hidden entirely behind the teeth, and for many adults that invisibility is worth the premium. Expect to pay somewhere between £2,000 and £10,000 or more privately in 2026, with the exact figure driven by your case complexity and the system your orthodontist uses. They are not available on the NHS, and the only reliable price is the one you are quoted at a consultation with a GDC-registered specialist.
If you are ready to take the next step, search for a dentist near you on Dentists Closeby to find a GDC-registered practice and arrange a consultation. A short conversation with a specialist orthodontist will tell you whether lingual braces are right for your smile and exactly what your treatment will cost.
