If you've ever wondered whether you or your child might qualify for orthodontic treatment on the NHS, you're not alone. Eligibility isn't always obvious — and many people wait years before asking, only to find out later that they either qualified earlier or could have explored private options sooner. That's exactly why we built our NHS orthodontic eligibility checker — a quick online tool that gives you a clear early indication of where you stand, based on the same clinical principles orthodontists use every day. Key takeaway NHS orthodontic treatment is only available for children and young people under 18 who score 3 or above on the IOTN scale. Use our NHS eligibility checker or IOTN score checker to get an indication in minutes — no appointment needed. The checker is a quick online tool designed to give you an early indication of whether orthodontic treatment may be available on the NHS. It's based on the same clinical principles orthodontists use every day, including the Index of Orthodontic Treatment Need (IOTN) — the system used across the UK to assess how necessary treatment is from a health perspective. It's not a diagnosis, and it doesn't replace a clinician — but it does give you clarity fast. Whether you're a parent researching options for your child, a teenager approaching 18, or an adult trying to understand whether any NHS route exists for you, the checker gives you an honest starting point. This is one of the most common points of confusion for patients searching for orthodontic help online. NHS orthodontic treatment is not available to adults in the UK. Eligibility is based on two criteria: You may qualify if You will not qualify if If you're approaching 17 and haven't yet started treatment, it's worth acting quickly. NHS orthodontic treatment must begin before the patient's 18th birthday — and NHS waiting lists can be long. Use our IOTN score checker to get an early indication of your score. The Index of Orthodontic Treatment Need (IOTN) is the clinical scoring system used across the UK to determine whether a patient qualifies for NHS orthodontic treatment. It has two components: Patients who score DHC grade 3, 4, or 5 are generally eligible for NHS treatment. Those scoring grade 1 or 2 are not considered to have sufficient clinical need. Our IOTN score checker walks you through the key criteria so you can get an early indication before speaking to a clinician. Most patients start with uncertainty — questions like: An online checker helps you understand whether NHS treatment is likely, possible, or unlikely before you commit any time to appointments. It also helps you avoid the frustration of waiting months for a consultation only to be told you don't meet the criteria. Find out if you or your child could qualify for NHS treatment. Our NHS eligibility checker gives you a clear early indication in minutes — no appointment, no obligation. Check eligibility now → The process is simple and patient-friendly: There's no commitment, no pressure, and no obligation to proceed. If NHS treatment isn't an option, you'll still know where you stand — and what private alternatives might look like. See our costs and pricing page for a full breakdown of private orthodontic treatment in the UK. Orthodontic issues don't just affect appearance — they can impact bite function, tooth wear, gum health, and long-term oral hygiene. Addressing them early, particularly in children and teenagers, tends to produce faster and more straightforward outcomes. Don't wait too long NHS orthodontic treatment is only available if treatment begins before the patient's 18th birthday. If your child is approaching 16 or 17 and you haven't yet explored eligibility, now is the time to act. NHS waiting lists can be significant — the earlier you start the process, the better. An early assessment also prevents missed eligibility windows. Even if treatment isn't needed right now, knowing that is valuable — it means you can monitor the situation with confidence rather than uncertainty.

If the checker indicates that NHS treatment is unlikely — either because of age, IOTN score, or clinical need — that doesn't mean orthodontic treatment isn't an option. Private treatment is available to patients of all ages, and many UK practices offer 0% finance over 12–24 months to help spread the cost.
