NHS braces for under-18s: Who qualifies and who doesn't?

In the UK, NHS orthodontic treatment is free for under-18s but only if your child meets strict medical criteria. Eligibility is determined using the Index of Orthodontic Treatment Need (IOTN), which assesses how much the bite and alignment affect oral function, not appearance. Children assessed as IOTN Grade 4 or 5 automatically qualify.
These cases usually involve significant crowding, bite issues, or jaw problems that could affect chewing or speech. Grade 3 cases are borderline and reviewed individually. Grades 1 and 2 with mild crowding or spacing are not eligible.
Even when a child qualifies, waiting times can be long. In many areas, waits of 12 to 24 months are common. NHS treatment typically includes only metal fixed braces, with no cosmetic upgrades.
What the NHS does not cover for under-18s
It's important for parents to understand what NHS orthodontics does not provide. Cosmetic concerns alone are not considered a medical priority. That means slightly crooked teeth, small gaps, or alignment concerns that affect confidence but not function are usually excluded. The NHS also doesn't offer aesthetic brace options such as ceramic brackets, lingual braces, or clear aligners.
Appointments may be less flexible, and treatment planning follows standard protocols rather than personalised preferences. For families hoping for quicker treatment, more discreet braces, or greater choice, this is often where private orthodontics enters the conversation.
Private braces for under-18s: How much do they really cost?
Private orthodontic treatment offers shorter waiting times and more flexibility, but it comes with higher costs. Typical braces cost UK figures for under-18s include:
-
Metal braces cost: £2,000-£3,500
-
Ceramic or white braces: £3,000-£4,500
-
Lingual braces: £5,000-£7,000
The final price depends on treatment complexity, duration, and location. London and the South East often sit at the higher end of the scale. This is where Caspersmile's goal comes into play. Our goal is to make teeth straightening for people across the UK. And for that, we aren't only offering flexible payment plans, but we also cut our operational costs to ensure our upfront plans stay affordable.
Clear aligners for under-18s: Are they an alternative to braces?

Clear aligners are no longer just for adults. Many providers now offer aligner treatment suitable for teens with mild to moderate alignment issues. They're discreet, removable, and easier to clean than fixed braces. For teens, this matters. Aligners make brushing simpler, reduce food restrictions, and eliminate emergency visits caused by broken brackets or wires. They're also nearly invisible, which can significantly boost confidence during school years.
Clear aligners are not usually available through the NHS, but privately they're often more affordable than traditional braces, especially for less complex cases.

Why private orthodontic care appeals to many families
Private care isn't only about aesthetics. For many parents, it's about timing and control. NHS waiting lists can mean treatment starts years later than ideal. Teeth continue to shift during adolescence, sometimes making correction more complex. Private orthodontics allows families to start treatment sooner, choose appointment schedules that fit school life, and explore options beyond traditional metal braces. That flexibility can reduce stress for both parents and teens despite the higher braces price. Plus, if you're looking for more affordable options, check out the clear braces cost. They'll help you decide better.
Additional costs parents should know about
Beyond the headline treatment fee, there are additional costs parents should plan for. Private consultations may carry fees. Replacement aligners or broken brackets can add unexpected expenses. Retainers after treatment are essential and may cost £70-£200 or more, depending on the provider. Some plans include retainers; others charge separately. Understanding these extras helps you calculate the true orthodontic cost, not just the advertised price.
How treatment length affects braces cost
Treatment duration plays a big role in overall pricing. Shorter treatments usually cost less, while complex cases requiring longer monitoring increase costs. Some providers offer fixed pricing, while others adjust fees if treatment extends. Always ask whether refinements, additional aligners, or extended care are included. This clarity protects you from unexpected increases in fixed braces cost or aligner fees later on.
Payment plans and affordability for families
Many private providers offer payment plans to help families manage costs. Monthly instalments spread the braces cost over time, making private treatment more accessible. Some aligner providers also offer flexible plans without interest. For families balancing school expenses, transport, and daily living costs, this flexibility can make a real difference.
How to choose the right option for your child
Start by assessing severity. A dentist or orthodontist can help determine whether an NHS referral is appropriate. If your child doesn't qualify, consider lifestyle factors. Active teens involved in sports may prefer aligners to reduce injury risk. Teens who struggle with brushing often find aligners easier to manage. Comparing how much braces are in the UK for under-18s, and analysing their comfort, appearance, and timeline leads to better long-term outcomes.
When private orthodontics makes the most sense
Private treatment often makes sense when NHS eligibility isn't met, waiting times are too long, or aesthetic concerns are important. It's also common for families who want more control over treatment pace and scheduling. While private care increases braces cost UK, it can reduce emotional stress and uncertainty for teens during a sensitive stage of life.
Straight teeth shouldn't be a struggle
Orthodontic care for under-18s in the UK comes with trade-offs. NHS braces can be free, but not everyone qualifies, and waiting lists can delay care. Private braces offer flexibility but raise costs. Clear aligners provide a modern alternative, often more affordable than traditional private braces, with fewer lifestyle disruptions. Exploring options early ensures your child gets the best possible outcome without unnecessary stress.
