Last updated: March 2026. This guide compares the cost of every teeth straightening option available in the UK, including metal braces, ceramic braces, lingual braces, Invisalign, clear aligners, and at-home options, with NHS eligibility, finance plans, and safety advice.
Straighter teeth are one of the most searched-for dental treatments in the UK, with demand from adults rising sharply in recent years. According to the British Orthodontic Society, 76% of orthodontists report an increase in adult patients seeking treatment over the past three years, driven by video calls, social media, and a growing awareness of the options available.
But with prices ranging from free on the NHS to over £8,000 privately, choosing the right treatment can feel overwhelming. This guide breaks down every option with verified pricing, so you can make an informed decision about what is right for your smile and your budget.
How Much Does Teeth Straightening Cost in the UK?
The cost of teeth straightening in the UK varies significantly depending on the type of treatment, the complexity of your case, where you live, and whether you qualify for NHS treatment.
Here is a quick comparison of all available options:
| Treatment Type | Cost Range | Treatment Duration | Visibility | NHS Available? |
|---|---|---|---|---|
| Metal braces (NHS) | Free (eligible under-18s) | 18-36 months | Visible | Yes |
| Metal braces (private) | £1,800-£3,835 | 18-36 months | Visible | No |
| Ceramic braces | £2,500-£5,000 | 18-36 months | Less visible | No |
| Lingual braces | £3,500-£8,825 | 18-36 months | Hidden | No |
| Invisalign (Express) | £1,200-£2,000 | 3-6 months | Nearly invisible | No |
| Invisalign (Full) | £3,500-£5,500 | 12-24 months | Nearly invisible | No |
| Other clear aligners | £2,500-£4,500 | 6-18 months | Nearly invisible | No |
| At-home aligners | £1,299-£2,000 | 4-8 months | Nearly invisible | No |
Important: All private prices are indicative ranges. Actual costs depend on your case complexity, treatment duration, and location. Always request a written treatment plan and quote from your chosen provider.
Metal Braces Cost UK
Traditional metal braces remain the most widely used and most affordable option for teeth straightening. They use metal brackets bonded to the front of each tooth, connected by a wire that is gradually tightened to move teeth into position.
NHS Metal Braces: Free for Eligible Children
NHS orthodontic treatment is available free of charge for children and young people who meet specific clinical criteria. Eligibility is assessed using the Index of Orthodontic Treatment Need (IOTN), a standardised scoring system that measures how severe the alignment problem is.
| IOTN Grade | Description | NHS Eligibility |
|---|---|---|
| Grade 1 | Near-perfect alignment | Not eligible |
| Grade 2 | Minor irregularities | Not eligible |
| Grade 3 | Moderate irregularities | Borderline (assessed individually) |
| Grade 4 | Severe irregularities | Eligible |
| Grade 5 | Very severe, health-affecting | Eligible (high clinical need) |
To qualify for free NHS treatment, children must be under 18 (or under 19 if in full-time education) and score IOTN Grade 4 or 5. Grade 3 cases may qualify if the aesthetic component score is 6 or above.
"Eligibility for free NHS orthodontic treatment is based on the severity of malocclusion measured using the Index of Orthodontic Treatment Need (IOTN) and the age of the patient." — British Orthodontic Society, NHS Treatment Eligibility
NHS Band 3 costs by nation (for those who need to pay):
| Nation | Band 3 Cost | Notes |
|---|---|---|
| England | £326.70 | From April 2025 |
| Wales | £260.00 | New contract from April 2026 |
| Scotland | 80% of cost, max £384 | Under-26s treated free |
| Northern Ireland | 80% of cost, max £384 | Similar to Scotland |
Be aware of NHS waiting times. Research published in the British Dental Journal in 2025 found that 351,208 children were waiting for NHS orthodontic assessments in England, with the longest documented wait being 6.6 years. Only 1 in 42 NHS Integrated Care Boards met the 18-week referral target. Families with eligible children should get on the waiting list as soon as possible.
Private Metal Braces Pricing
For adults or those who do not qualify for NHS treatment, private metal braces are the most affordable orthodontic option.
| Treatment | Cost Range |
|---|---|
| Single arch | From £1,800 |
| Dual arch (full treatment) | £2,200-£3,835 |
| London practices | £2,500-£3,500 |
What is included: Most private treatment packages include the braces, all adjustment appointments, and a retainer at the end of treatment. Always confirm exactly what is covered before committing.
Pros: Most affordable private option, effective for all case types including complex misalignment, very durable, precise tooth movement.
Cons: Most visible type of braces, dietary restrictions on hard and sticky foods, oral hygiene requires more effort, monthly adjustment appointments needed.
Ceramic Braces Cost UK
Ceramic braces work in the same way as metal braces but use tooth-coloured or clear brackets that blend in with your teeth. They are a popular choice for adults who want the reliability of fixed braces with a more discreet appearance.
| Treatment | Cost Range |
|---|---|
| Single arch | From £2,500 |
| Dual arch (full treatment) | £2,500-£5,000 |
| London practices | £3,000-£6,000 |
Treatment duration: 18-36 months, with no significant difference compared to metal braces for the same case.
How ceramic compares to metal braces:
| Factor | Metal Braces | Ceramic Braces |
|---|---|---|
| Visibility | Highly visible | Tooth-coloured, less visible |
| Cost | £1,800-£3,835 | £2,500-£5,000 |
| Durability | Very durable | Slightly more fragile |
| Staining | No staining | Brackets and ties can stain |
| Effectiveness | Full range of cases | Full range of cases |
Pros: Much less visible than metal braces, same effectiveness and treatment time, more affordable than lingual braces or Invisalign.
Cons: More expensive than metal braces, ceramic brackets can stain with coffee, tea, or red wine, slightly more fragile than metal brackets.
Lingual Braces Cost UK
Lingual braces are fixed to the inside surface of your teeth (the tongue-facing side), making them completely invisible from the outside. They are custom-made for each patient and must be fitted by a specialist orthodontist.
Only around 10% of the UK's registered orthodontic specialists offer lingual braces, which contributes to their higher cost.
| Treatment | Cost Range |
|---|---|
| Standard lingual braces (per arch) | £2,000-£3,000 |
| Full lingual braces (dual arch) | £3,500-£8,825 |
| Incognito (premium, fully customised) | £4,800-£8,825 |
| London practices | £4,800-£10,000 |
Treatment duration: 18-36 months, similar to traditional braces. Mild cases may take as little as 6-12 months.
Why lingual braces cost more:
- Specialist training required (only a minority of orthodontists offer them)
- Custom-made using computer-aided design
- More technically demanding to fit and adjust
- Longer appointment times
Pros: Completely invisible from the outside, equally effective as facial braces, suitable for complex cases, custom-fitted to each tooth.
Cons: Most expensive fixed brace option, initial speech difficulties as your tongue adjusts, tongue discomfort in the first few weeks, harder to clean, fewer orthodontists offer this treatment.
Invisalign and Clear Aligner Cost UK
Invisalign is the world's leading clear aligner system, using a series of custom-made, removable transparent plastic trays that are changed approximately every one to two weeks. Treatment must be supervised by a trained Invisalign provider.
Invisalign Pricing Tiers
Invisalign offers several treatment levels depending on the complexity of your case:
| Invisalign Product | Case Complexity | Duration | Cost Range |
|---|---|---|---|
| i7 (Express) | Very minor corrections | 3-6 months | £1,200-£2,000 |
| Lite | Mild to moderate | 6-8 months | £2,500-£4,000 |
| Moderate | Moderate corrections | 12-18 months | £2,800-£3,500 |
| Full | Complex cases | 12-24 months | £3,500-£5,500 |
| Comprehensive | Most complex, with refinements | 18-36 months | £4,500-£5,500+ |
London pricing: Invisalign in central London typically starts at approximately £4,120, reflecting higher operating costs, though competition between practices can keep prices competitive.
What is typically included: Most practices bundle the initial consultation and 3D digital scan, all aligner trays, regular check-up appointments (every 6-8 weeks), refinement aligners if needed, and final retainers (though this varies, so always confirm).
Other Clear Aligner Brands
Invisalign is not the only option. Other dentist-supervised clear aligner systems available in the UK include:
| Brand | Cost Range | Notes |
|---|---|---|
| ClearCorrect | £2,500-£4,500 | Often more affordable than Invisalign |
| Angel Aligners | £3,015-£4,865 | Available at selected practices |
| AccuAligners | £1,800-£3,500 | UK-based alternative |
All dentist-supervised clear aligners involve regular in-person check-ups and clinical oversight throughout treatment.
Pros of clear aligners: Nearly invisible, removable for eating and brushing, no dietary restrictions, fewer appointments than fixed braces, comfortable to wear.
Cons of clear aligners: Requires discipline (must be worn 20-22 hours per day), not suitable for all case types, may be slower for complex cases, aligners can be lost or damaged.
At-Home Aligners: Cost and Safety Warnings
At-home (or direct-to-consumer) aligners are clear aligner systems where patients take impressions at home or attend a brief scan at a shop, then receive aligners by post without regular in-person clinical supervision.
How Much Do At-Home Aligners Cost?
| Option | Cost Range | Supervision Level |
|---|---|---|
| At-home aligners (e.g. NewSmile, Caspersmile) | £599-£2,000 | Minimal or remote only |
| Hybrid (initial dentist visit, then remote) | £1,500-£2,500 | Limited |
| Dentist-supervised aligners (Invisalign, ClearCorrect) | £2,500-£5,500 | Full clinical supervision |
While at-home aligners are significantly cheaper, there are serious safety concerns that you must be aware of before choosing this route.
Are At-Home Aligners Safe?
The General Dental Council (GDC), the British Dental Association (BDA), and the Care Quality Commission (CQC) have all raised significant safety concerns about direct-to-consumer orthodontic treatment.
"Clinical judgements about the suitability of a proposed course of orthodontic treatment must be based on a full assessment of the patient's oral health. At present, there is no effective substitute for a physical, clinical examination as the foundation for that assessment." — General Dental Council, Statement on Direct-to-Consumer Orthodontic Treatment
Key risks identified by regulators:
- Without an in-person examination, a dentist may miss conditions that make aligners unsafe (such as gum disease, tooth decay, or root problems)
- If forces are applied to teeth with underlying disease, patients risk permanent tooth loss
- Poor-quality impressions taken at home can result in poorly fitting aligners that damage teeth
- The BDA has warned that DTC orthodontics "can lead to fundamental changes to a patient's mouth that may be irreversible"
SmileDirectClub, once the largest at-home aligner company, filed for bankruptcy in December 2023 with approximately $900 million in debt, leaving customers without support or follow-up care.
"Direct-to-consumer orthodontic services fall within the legal definition of dentistry and can only be performed by a GDC-registered dental professional." — General Dental Council, Statement on DTC Orthodontics
Our recommendation: Always choose orthodontic treatment supervised by a GDC-registered dentist or orthodontist who provides a full clinical examination before starting treatment. The savings from at-home aligners are not worth the risk of irreversible damage.
Can Adults Get Braces on the NHS?
In short: very rarely.
"Orthodontic treatment is not usually available on the NHS for adults." — NHS, Orthodontics
NHS orthodontic treatment for adults is only considered when there is a clear medical need, not for cosmetic improvement. This includes:
- Difficulty chewing or biting properly
- Jaw pain related to misalignment
- Speech problems caused by tooth position
- Risk of damage to other teeth
Adults who may qualify are typically referred to the Hospital Orthodontic Service (secondary care) and must score IOTN Grade 4 or 5. In practice, very few adults receive NHS orthodontic treatment, and waiting times can be extremely long.
For the vast majority of adults, private treatment is the only option. The good news is that finance plans (detailed below) make treatment accessible from around £50-£85 per month.
Cheapest Way to Straighten Teeth in the UK
If budget is your primary concern, here are your options ranked from least to most expensive:
| Rank | Option | Cost | Important Notes |
|---|---|---|---|
| 1 | NHS braces | Free (if eligible) | Under-18s only, long waiting times |
| 2 | Invisalign i7/Express | £1,200-£2,000 | Very minor corrections only |
| 3 | Metal braces (private) | £1,800-£3,835 | Best value for complex cases |
| 4 | Ceramic braces | £2,500-£5,000 | Less visible fixed option |
| 5 | Invisalign Full | £3,500-£5,500 | Premium removable option |
| 6 | Lingual braces | £3,500-£8,825 | Completely hidden |
Tips for reducing costs:
- Get multiple quotes. Prices vary significantly between practices, even in the same area. Get at least two or three written quotes before committing.
- Ask about payment plans. Most practices offer 0% finance, making even premium treatments affordable month-to-month.
- Consider treatment outside London. London prices are typically 15-20% higher than the national average.
- Check what is included. Some practices include retainers, X-rays, and all adjustments in the quoted price. Others charge separately, which can add £200-£500 to the total cost.
- Ask about discounts. Some practices offer 5-10% off for paying the full amount upfront.
How to Pay for Teeth Straightening
0% Finance and Payment Plans
The majority of private orthodontic practices across the UK offer 0% interest finance plans, allowing you to spread the cost of treatment into manageable monthly payments.
Typical 0% finance terms:
| Treatment Cost | Monthly Payment (12 months) | Monthly Payment (24 months) | Monthly Payment (36 months) |
|---|---|---|---|
| £1,800 | £150 | £75 | £50 |
| £3,000 | £250 | £125 | £83 |
| £3,500 | £292 | £146 | £97 |
| £5,000 | £417 | £208 | £139 |
Key points about dental finance:
- 0% APR is widely available on terms up to 24-36 months
- Longer terms (48-60 months) typically attract interest at around 7.9-9.9% APR
- Finance providers include Novuna Personal Finance and Chrysalis Finance
- Decisions are usually provided within minutes
- Many practices offer no-deposit options
- Some practices deduct the consultation fee from the total if you proceed with treatment
Does Dental Insurance Cover Orthodontics?
Most standard dental insurance plans do not cover orthodontic treatment, or provide only limited cover. If you are considering dental insurance specifically for orthodontics, be aware:
- Most insurers impose a minimum holding period of 12 months before orthodontic claims are accepted
- Cover is typically limited to £300-£500 per year, which will not cover the full cost
- Some policies only pay out after treatment is complete, not upfront
- Cosmetic orthodontics is usually excluded entirely
Dental insurance is generally better suited for routine check-ups and unexpected dental emergencies than for planned orthodontic treatment. Finance plans offered directly by practices are usually a more practical route.
How to Choose the Right Treatment
Choosing the right teeth straightening treatment depends on several factors:
| Factor | Best Options |
|---|---|
| Budget is the priority | Metal braces (cheapest private option) or NHS if eligible |
| Appearance matters | Invisalign, ceramic braces, or lingual braces |
| Complex case | Metal or ceramic braces, Invisalign Full/Comprehensive |
| Mild correction needed | Invisalign i7/Lite (shortest treatment time) |
| Complete invisibility | Lingual braces (only truly hidden option) |
| Lifestyle flexibility | Clear aligners (removable for eating and brushing) |
Steps to take:
- Book a consultation with a GDC-registered orthodontist or dentist. Many offer free initial consultations.
- Get a full assessment including X-rays and a 3D scan of your teeth.
- Discuss all options and ask about the expected treatment duration, total cost, and what is included.
- Get a written treatment plan with a clear breakdown of all costs before committing.
- Check the provider is registered on the GDC Register and the practice is CQC-registered.
- Compare quotes from at least two or three providers.
Retainers: The Hidden Cost to Budget For
After any teeth straightening treatment, you will need retainers to prevent your teeth from moving back to their original position. Some practices include retainers in the treatment price, but others charge separately.
| Retainer Type | Cost per Arch |
|---|---|
| Fixed bonded retainer (permanent wire) | £100-£400 |
| Removable clear retainer | £150-£450 |
| Replacement removable retainer | £100-£250 |
Always ask whether retainers are included in your quoted treatment cost.
Frequently Asked Questions
How much do braces cost in the UK in 2026?
Private braces in the UK cost between £1,800 and £8,825 depending on the type. Metal braces are the most affordable at £1,800-£3,835, ceramic braces cost £2,500-£5,000, and lingual braces (hidden behind the teeth) cost £3,500-£8,825. NHS braces are free for eligible children under 18 who meet the clinical need criteria.
Can I get braces on the NHS as an adult?
NHS orthodontic treatment for adults is extremely rare. The NHS states that "orthodontic treatment is not usually available on the NHS for adults." It is only considered when there is a clear medical need such as difficulty chewing or jaw pain, not for cosmetic improvement. Most adults need to pay for private treatment.
What is the cheapest way to straighten teeth in the UK?
If you qualify for NHS treatment (under 18 with IOTN Grade 4-5), braces are free. For adults paying privately, metal braces are the cheapest option at £1,800-£3,835. Invisalign Express (for very minor corrections) starts from £1,200. Most practices offer 0% finance plans, making monthly payments as low as £50-£85.
How long does teeth straightening take?
Treatment duration depends on the method and case complexity. Invisalign Express for minor corrections takes 3-6 months. Standard braces and full Invisalign treatment typically take 12-24 months, with more complex cases taking up to 36 months. Your orthodontist will give you an estimated timeline during your consultation.
Are at-home aligners safe?
The GDC, BDA, and CQC have raised serious safety concerns about at-home aligners. The GDC states there is "no effective substitute for a physical, clinical examination" before orthodontic treatment. Without proper clinical supervision, patients risk permanent damage including tooth loss. Always choose treatment supervised by a GDC-registered professional.
Is Invisalign worth the money compared to braces?
Invisalign and traditional braces are both effective for straightening teeth. Invisalign costs more (£2,500-£5,500 vs £1,800-£3,835 for metal braces) but offers advantages: nearly invisible appearance, removable for eating and brushing, and fewer appointments. However, braces may be better for complex cases and are the only option available on the NHS. The right choice depends on your case, budget, and lifestyle.
Do I need retainers after teeth straightening?
Yes, retainers are essential after any orthodontic treatment. Without them, your teeth will gradually shift back toward their original position. Most orthodontists recommend wearing retainers indefinitely (nightly for at least the first year, then several nights a week long-term). Retainers cost £100-£450 per arch and may or may not be included in your treatment price.
Finding the Right Provider
When choosing a provider for teeth straightening, look for:
- GDC registration - Verify your dentist or orthodontist is registered on the GDC Register
- CQC registration - Check the practice is registered with the Care Quality Commission (England)
- Specialist qualifications - Orthodontic specialists are listed on the GDC Specialist Register
- Written treatment plan - A clear breakdown of costs, treatment time, and what is included
- Finance options - 0% interest plans to make treatment affordable
- Reviews and recommendations - Check independent reviews from previous patients
