NHS Orthodontics in the UK

NHS orthodontic treatment in England is available to children and young people under the age of 18 whose teeth meet a clinical need threshold, measured by the Index of Orthodontic Treatment Need (IOTN). Scores of 4 or 5 on the dental health component typically qualify; scores of 1 and 2 do not; grade 3 is borderline and depends on the local NHS provider's capacity. Adults are not routinely eligible for NHS orthodontic treatment — exceptions exist for hospital-led cases involving orthognathic (jaw) surgery, cleft palate, or other significant clinical needs, but these are rare. Scotland, Wales, and Northern Ireland have slightly different eligibility criteria.

The Index of Orthodontic Treatment Need (IOTN) is a clinical scoring tool used to measure the severity of an orthodontic case. It includes a dental health component (assessing crowding severity, bite problems, missing teeth, and similar factors) and an aesthetic component (how the teeth look). Scores range from 1 (no need for treatment) to 5 (great need). NHS treatment is generally provided for scores of 4 and 5. Score 3 is borderline — some NHS providers will accept grade 3 cases, others will not, depending on local capacity. Your dentist or an orthodontist can assess your IOTN score during a routine check-up.

NHS orthodontic waiting times vary significantly by area. In many parts of England, the wait between referral and starting treatment is four years or more, though around six months in lower-demand areas. Waiting times increased substantially following the pandemic backlog and have not fully recovered in most regions. Your dentist can advise on the estimated wait for local NHS orthodontic providers when making a referral. If your child qualifies for NHS treatment but the wait is very long, private orthodontic treatment is an option — the NHS referral typically remains valid while you wait, so you are not necessarily choosing one or the other permanently.

No. NHS orthodontic treatment uses standard fixed metal braces in the vast majority of cases. Ceramic braces, lingual braces, and clear aligners (such as Invisalign) are not funded under NHS contracts because they are considered cosmetic options beyond clinical need. If you or your child qualifies for NHS treatment but wants a less visible appliance, the options are to wait for NHS metal braces at no cost, or to access private treatment with a wider range of appliance choices at personal cost. Some families choose to wait for NHS treatment for the clinical need and accept the appliance type; others prefer to go private for the additional choice.

NHS orthodontic treatment is provided under a Band 3 dental charge in England. From 1 April 2026 this is £332.10 for the full course of treatment — this covers all brace appointments, adjustments, and related clinical visits during active treatment. Patients under 18 with a qualifying referral receive NHS treatment at this charge; some patients (those on income-related benefits, NHS Low Income Scheme, etc.) may be exempt from the charge entirely. Retainers after NHS treatment may be included initially, but replacements may be charged separately. In contrast, private orthodontic treatment typically costs £1,500–£5,500 depending on the appliance and case complexity.

Yes — and many families do. If your child has been referred for NHS treatment and is on a waiting list, you can begin private treatment in the meantime. The NHS referral does not lapse simply because you started private treatment, though you should check with the local NHS provider about their specific waiting list policy. Starting private treatment while on a list does not guarantee you will be able to resume NHS treatment later — some providers will remove patients from the waiting list if they start private treatment. Private treatment allows you to begin sooner, choose the appliance type, and often have shorter appointment waiting times.

If the IOTN assessment gives a score below the qualifying threshold (typically score 1, 2, or borderline 3), NHS treatment will not be offered. This means the case does not meet the clinical need criteria, not necessarily that treatment is impossible — it may simply mean the need is mild or primarily cosmetic. Private orthodontic treatment is available regardless of IOTN score for patients of any age. A private orthodontist can assess whether treatment would benefit your child and, if so, what options are available and at what cost.

NHS orthodontic treatment meets the same clinical standards as private treatment for the cases it accepts. The main differences are appliance choice, waiting times, and access for adults. NHS treatment is almost exclusively metal fixed braces; private treatment offers ceramic braces, lingual braces, and clear aligners such as Invisalign. NHS waiting lists in many areas now run to four years or more, while private treatment typically starts within weeks. For eligible children, NHS treatment is clinically appropriate and cost-effective; for adults or families wanting faster access or more appliance options, private is often the only practical route.
