For most parents, the question isn't whether their child's teeth might need treatment — it's when to start asking, and who to ask. Orthodontic treatment for children is one of the more confusing areas of dentistry: the right timing genuinely matters, NHS and private routes work differently, and the options available at different ages vary more than most people realise. This guide explains what the key considerations typically are, what signs are worth watching for, and what an assessment involves. It is for general information only and does not replace clinical advice specific to your child.
Why Timing Matters
The jaw and teeth develop actively through childhood and into the early teenage years. Some treatment is most effective — or only possible — at specific stages of this development. Acting too early can mean treatment that needs to be repeated later; acting too late means missing the natural growth windows that make certain corrections more straightforward.
The general principle is: the earlier a concern is identified, the more options are typically available. This doesn't mean all children need early treatment — it means that having an orthodontic assessment at the right time gives you the information to make a well-timed decision.
When Should My Child Have an Orthodontic Assessment?
The British Orthodontic Society recommends considering a referral for an orthodontic assessment around age 10–11 — before all the adult teeth have come through, but late enough for a meaningful picture of how the teeth and jaws are developing. Some concerns may warrant an earlier assessment:
- Crossbites (where the top and bottom teeth don't meet correctly on one or both sides) are often easier to address before the jaws have fully formed
- Thumb-sucking or prolonged dummy use affecting the bite can sometimes be addressed earlier
- Missing or extra teeth are often easier to manage with early planning
- Crowding that is affecting the eruption of adult teeth may benefit from earlier assessment
If in doubt, it is always reasonable to ask your child's regular dentist whether a referral is appropriate.
What Can Be Treated, and When
The most common reasons for braces in children include crowding, spacing, protruding front teeth, crossbites, and deep bites. The approach and timing depend on which adult teeth are present and how the jaws are positioned.
Earlier intervention (typically age 7–10) may address issues where jaw development can be influenced before growth is complete. Not all children need this — but for those with certain significant bite problems, earlier assessment can help clarify whether treatment at this stage would be beneficial.
Comprehensive treatment (typically age 11–14) is the most common stage for full orthodontic treatment — once the majority of adult teeth have come through. Fixed braces, removable appliances, or in some cases clear aligners may be options depending on the clinical situation.
NHS vs Private Orthodontic Treatment
NHS orthodontic treatment is available to children under 18 in England who meet the clinical criteria assessed using the Index of Orthodontic Treatment Need (IOTN). This considers both the functional impact (bite, jaw function) and the aesthetic severity of the concern.
Key points about NHS treatment:
- It is free at the point of treatment for eligible patients
- Treatment is with fixed braces in the majority of cases
- Waiting times vary significantly by area — some areas have waits of 18–24 months or more for non-urgent cases
- Not all orthodontic concerns meet the clinical threshold for NHS treatment, even if they are noticeable
Private orthodontic treatment covers a wider range of concerns (including those that don't meet the NHS threshold) and may offer a broader choice of appliances — including clear aligners. It typically begins sooner and may involve different appliance options. The cost varies by practice and treatment type.
Your child's dentist can advise on whether your child is likely to meet the NHS criteria and provide a referral if appropriate.
What Does an Orthodontic Assessment Involve?
An initial assessment typically includes:
- A clinical examination of the teeth, bite, and jaw
- Photographs of the teeth and face from different angles
- X-rays to show the position of teeth not yet visible and the roots of existing teeth
- Impressions or a digital scan of the teeth
- A discussion of treatment options, timing, and — for private treatment — indicative costs
The assessment is an information-gathering exercise. You are not committing to treatment by attending one, and a good orthodontist will tell you honestly if treatment is likely to be needed, when the right time is, or whether the situation warrants monitoring rather than active intervention.
Questions Worth Asking
At an orthodontic assessment, the following questions are often useful:
- Does my child need treatment now, or is it better to wait?
- If we wait, what are we monitoring for and how long?
- What are the realistic options for treatment — appliance types, duration, phasing?
- Is my child likely to meet the criteria for NHS treatment?
- What does retention look like after treatment (retainers are typically worn long-term)?
- What happens if treatment is started and my child doesn't comply well with wearing the appliance?
Important Note
This guide is for general information purposes only and does not constitute clinical advice. Orthodontic needs vary significantly between children — the information here is not a substitute for assessment by a qualified orthodontist or dental professional. NHS eligibility, treatment options, and timing should be discussed with a qualified practitioner who has examined your child.
