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.

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:

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:

Traditional metal fixed braces12-24 months£1,500-3,000

Frequently asked questions

Can adults get braces on the NHS?
Orthodontic treatment is not usually available on the NHS for adults. The NHS provides free orthodontics to under-18s with clear clinical need; adults only qualify in rare cases of significant functional or health problems, where they are typically referred to a hospital orthodontic service and must score IOTN grade 4 or 5. Most adults who want their teeth straightened pay for private treatment.
How much do adult braces cost on the NHS?
Where an adult does qualify for NHS orthodontic treatment, it is charged at NHS Band 3, which is £332.10 from 1 April 2026. Band 3 covers the full course of orthodontic appliances and all preparatory work. In practice very few adults are approved, so this charge applies only to the small number of clinically-justified cases.
How much do private adult braces cost in the UK in 2026?
The NHS notes private orthodontics is widely available but expensive, typically £2,000 to £6,000 depending on complexity. By type: traditional metal fixed braces £1,500-3,000, ceramic (tooth-coloured) fixed braces £2,000-4,000, clear aligners such as Invisalign £2,000-5,500, and lingual (behind-teeth) braces £4,000-8,000. London is typically 30-50% higher.
What IOTN grade does an adult need for NHS braces?
Adults referred for possible NHS orthodontic treatment generally need to score IOTN grade 4 or 5 on the Dental Health Component, the same severe-need threshold used for borderline children's cases (grade 3 with an aesthetic score of 6 or above can qualify for under-18s). Cosmetic-only misalignment does not qualify at any age.
Where can adults get cheaper braces if not on the NHS?
Options include treatment at a UK dental school under supervised student-led care (typically £500-1,500 for a full course where available), shorter cosmetic systems such as Six Month Smiles (£1,800-3,500) for mild front-tooth correction, and spreading private treatment over monthly payment plans many practices offer. Always confirm whether retainers are included in the quoted price.
