Can I get braces on the NHS?
By The Local Dentist Editorial · Updated 13 July 2026
The under-18 rules: clinical need, not cosmetics
NHS orthodontics for children and teenagers is rationed by clinical need, measured with the Index of Orthodontic Treatment Need (IOTN). A dentist or orthodontist grades how much the position of the teeth and bite threatens dental health — things like significant crowding, teeth that stick out and risk injury, deep bites damaging gums, or impacted teeth. Clear clinical need qualifies for free NHS treatment; mild, essentially cosmetic irregularity does not, however much it bothers the patient. Borderline grades get a secondary aesthetic assessment to decide. The threshold exists to point NHS resources at the cases where treatment protects health, and it means some disappointed families — an honest orthodontic assessment will tell you which side of the line a child falls.
How to get assessed — and the waiting list reality
The route starts at your child's dentist: regular NHS check-ups (free for under-18s) are where orthodontic problems get spotted, usually from around age 10–13 as adult teeth come through. The dentist refers qualifying cases to an NHS orthodontist for IOTN assessment and treatment. Be prepared for waiting lists — in many areas the wait for NHS orthodontic treatment runs long, and referral-to-brace times of a year or more are common. Practical advice: do not wait for a problem to become obvious; keep up routine check-ups, ask the dentist directly about orthodontic timing, and get the referral in early. Treatment must generally start before 18 to be NHS-funded, so late referrals risk missing the window.
Adults: why the NHS answer is almost always no
NHS orthodontics for adults is rare and reserved for severe cases with exceptional clinical need — typically complex bite problems requiring joint orthodontic and jaw surgery care, handled through hospital services after referral. A crooked smile that affects confidence, however genuinely, does not meet the bar. That leaves private treatment as the realistic adult route: fixed metal or ceramic braces, or clear aligners such as Invisalign, which typically cost £1,500–5,500 depending on complexity. Prices are set per practice, quotes vary in what they bundle (refinements and retainers matter most), and comparing two or three consultations is worthwhile — see our Invisalign cost answer and the Invisalign vs braces guide for how to weigh the options.
What NHS treatment includes — and doesn't
Qualifying NHS orthodontic treatment for under-18s is free, including the assessment, the braces themselves, adjustments, and retainers at the end of treatment. But it comes with constraints: the NHS provides fixed braces — metal 'train-track' braces — not clear aligners or discreet ceramic options, which are private choices. Missed appointments and broken braces can jeopardise NHS treatment, so commitment matters; treatment typically runs 18 months to two years of regular adjustments. After treatment, wearing retainers as instructed is what stops teeth drifting back — replacement retainers later in life are usually a private cost, and relapse needing re-treatment in adulthood means private prices. Families wanting aligner-style treatment for a qualifying teenager can choose to go private instead; both routes are legitimate, and a consultation will price the difference.
People Also Ask
What is IOTN?
The Index of Orthodontic Treatment Need — the grading system NHS orthodontists use to measure how much a child's tooth and bite position threatens dental health. Meeting the threshold qualifies for free NHS braces; purely cosmetic cases do not.
Can my child get Invisalign on the NHS?
No. NHS orthodontic treatment uses fixed braces. Clear aligners are private treatment, typically £1,500–5,500, whatever the patient's age.
How long are NHS braces waiting lists?
It varies by area, but long waits are common — often a year or more from referral to starting treatment. Ask your dentist for a referral early rather than waiting for problems to worsen.
Can adults ever get NHS braces?
Only in severe cases with exceptional clinical need, typically involving hospital-based care such as combined orthodontic and jaw surgery. For cosmetic straightening, adults use private braces or aligners.
