Adult Braces on the NHS: Cost and Eligibility
Orthodontic treatment is not usually available on the NHS for adults. Where an adult does qualify on clinical grounds, braces are charged at NHS Band 3 (£332.10). Almost all adult braces in the UK are paid for privately, typically £2,000 to £6,000.
QUICK ANSWER
Adults are rarely eligible for NHS braces. The NHS states orthodontic treatment “is not usually available on the NHS for adults” and is mainly for under-18s with clear clinical need. The small number of adults approved (usually severe functional problems, referred to a hospital orthodontic service at IOTN grade 4 or 5) pay the Band 3 charge of £332.10 for the whole course. Everyone else goes private, where braces cost £2,000 to £6,000 depending on the type and complexity.

Going rate for private adult braces and aligners in the UK, varying by appliance type, complexity and location.
Can adults get braces on the NHS?
In almost all cases, no. NHS orthodontic funding is directed at under-18s with a clear clinical need, assessed using the Index of Orthodontic Treatment Need (IOTN). The NHS is explicit that “orthodontic treatment is not usually available on the NHS for adults.”
The narrow exception is adults with significant functional or health problems, not appearance alone. These cases are typically handled in secondary care through a hospital orthodontic service rather than a high street practice, and usually need to score IOTN grade 4 or 5 (the severe-need grades). Examples include orthodontics as part of corrective jaw surgery, or cleft palate care. Waiting lists for these services can be long.
The simple test
If you want straighter teeth mainly for appearance, NHS braces are not available to you as an adult and you will need private treatment. If a dentist or doctor has identified a functional bite problem or you are having jaw surgery, ask for an NHS orthodontic assessment and referral.
What adult NHS braces cost if approved
Where an adult does qualify, orthodontic treatment is an NHS Band 3 course. From 1 April 2026 the Band 3 charge is £332.10. That single charge covers the whole course of treatment, including:
- Assessment, IOTN scoring, treatment planning and impressions or scans.
- Fitting of the appliance (metal fixed braces are standard NHS).
- All routine adjustment appointments through treatment.
- Removal of the braces and fitting of retainers.
You do not pay per appointment. If you are exempt from NHS dental charges (for example on certain benefits, under the Low Income Scheme, or pregnant), the £332.10 is reduced or free. See who gets free NHS dental treatment.
Private adult braces costs (2026)
Because NHS adult orthodontics is so limited, most adults pay privately. The NHS describes private orthodontics as “widely available, but expensive,” typically £2,000 to £6,000. Costs by appliance type:
| Treatment type | Typical duration | Private cost (UK 2026) |
|---|---|---|
| Traditional metal fixed braces | 12-24 months | £1,500-3,000 |
| Ceramic (tooth-coloured) fixed braces | 12-24 months | £2,000-4,000 |
| Clear aligners (Invisalign, ClearCorrect) | 6-18 months | £2,000-5,500 |
| Lingual (behind-teeth) braces | 12-24 months | £4,000-8,000 |
| Six Month Smiles / short-term cosmetic | 6 months | £1,800-3,500 |
| Retainers after treatment | Lifetime use | Often included; £100-300 if separate |
Headline £2,000-6,000 range from nhs.uk orthodontics guidance. Per-type ranges from Which? UK orthodontic cost guides and Bupa Dental Care published price tiers. London is typically 30-50% higher.
Cheaper routes for adults
- Dental schools. Some UK dental schools offer supervised, student-led orthodontic treatment at reduced cost, typically £500-1,500 for a full course of fixed braces where places are available.
- Short-term cosmetic systems. For mild front-tooth correction, systems such as Six Month Smiles or short-course aligners (£1,800-3,500) cost less than full comprehensive treatment.
- Monthly payment plans. Most private practices spread the cost over the treatment period, often interest-free.
- Confirm retainers are included. Retainers are needed long-term; check whether they are in the quoted price or charged separately (£100-300).
