Most parents assume orthodontic treatment is something that happens in the teenage years — braces go on around twelve or thirteen, come off a couple of years later, and that is that. For the majority of children this is broadly correct. But for a significant minority, waiting until the teenage years to have a first orthodontic assessment means missing a window during which certain problems can be addressed more simply, more completely, and sometimes without the need for more extensive treatment later. Early orthodontic assessment for children — often recommended from around age seven — is not about putting children in braces young. It is about identifying which children will benefit from intervention during a specific window of jaw development, and which can safely wait. The distinction matters enormously for outcomes, cost, and the total duration of treatment a child will need. Key takeaway The American Association of Orthodontists and the British Orthodontic Society both recommend a first orthodontic screening at around age seven — not because most children need treatment at this age, but because certain conditions are best addressed during active jaw growth. These include crossbites, severely narrow arches, impacted teeth, and severe skeletal discrepancies. Interceptive treatment during the mixed dentition (age seven to ten) can simplify or sometimes eliminate the need for more complex treatment in the teenage years. For most children, however, the recommendation after an early screening will simply be to monitor and wait. Age seven is the recommended age for a first orthodontic screening because it represents a diagnostic sweet spot. By this age, enough permanent teeth have erupted — typically the first molars and the upper and lower front incisors — to allow an orthodontist to assess the bite relationship, identify any eruption problems, and make an informed early judgement about the likely developmental trajectory of the remaining teeth and jaw. Critically, this is also a period when the jaws are still actively growing and, in some cases, can still be influenced by orthopaedic appliances (appliances that guide jaw growth rather than just moving teeth). This window closes progressively as children approach puberty. For skeletal problems in particular, timing matters — the same jaw issue that can be modified with a removable appliance at age eight may require surgery to correct at age twenty-five. Not all orthodontic problems benefit from early treatment. Many are best addressed in the teenage years once the permanent teeth have fully erupted and any jaw growth modification window has been used as intended. But certain conditions are consistently more effectively managed when identified early: A crossbite occurs when one or more upper teeth bite inside the lower teeth when the jaws are closed. A posterior crossbite — where the back teeth on one side are in the wrong relationship — is one of the clearest indications for early treatment. A crossbite creates an asymmetrical loading of the jaw joint that, over years, can cause the lower jaw to shift habitually to one side. This shift can become structural — the jaw bones themselves begin to grow asymmetrically — if the crossbite is left uncorrected long into childhood. Early correction with a simple palatal expander or removable appliance is quick and highly effective; correcting the skeletal asymmetry it causes if left untreated is much more complex. A narrow upper arch — which may present as crowding, a high palate, or crossbite — can often be widened in children using a palatal expander, taking advantage of the midpalatal suture (the growth zone in the middle of the upper jaw) which remains open and expandable until the mid-teens. Expanding the upper arch in a child takes weeks to months; in an adult, the suture has fused and arch expansion requires either significant orthodontic force (with limited effect on bone width) or palatal expansion surgery. Canine teeth — the pointed teeth in the corners of the smile — are the most commonly impacted permanent teeth after wisdom teeth. Upper canines become impacted in approximately 2% of the population and, if not managed early, can cause root damage to adjacent teeth and require complex surgical-orthodontic treatment to bring them into the arch. Early monitoring and sometimes early extraction of the primary canine can encourage an impacted permanent canine to self-correct without surgery. This intervention is far simpler at age eight or nine than at sixteen. Some skeletal problems — where the upper and lower jaws are significantly mismatched in size or position — can be partially modified during the growth years. A significant overbite (where the upper front teeth protrude well in front of the lower) may be partially improved using a functional appliance during the growth spurt. This does not eliminate the need for fixed braces later, but it can reduce the severity of the problem and potentially avoid the need for jaw surgery in adult life. The timing of this intervention — ideally coinciding with the pubertal growth spurt at around eleven to thirteen — requires monitoring that begins with early assessment.

A virtual assessment can help 😀 A free virtual assessment allows a qualified clinician to review photographs of your child's teeth and advise whether an in-person orthodontic consultation is recommended at this stage. Start your free assessment → An early orthodontic assessment at a specialist practice typically involves: The consultation is not a commitment to treatment. Most seven-year-olds assessed by a specialist orthodontist are told to return in twelve to eighteen months for a review, with no treatment recommended at that stage. A small proportion will be identified as candidates for early interceptive treatment. And a small number will have findings that require prompt action. NHS orthodontic treatment in the UK is assessed using the Index of Orthodontic Treatment Need (IOTN), which scores the clinical severity of a malocclusion. Only children who meet the clinical threshold (IOTN grade 3.6 or above) are eligible for NHS-funded treatment. The IOTN assessment is typically done once the permanent teeth have erupted — meaning early interceptive treatment in the mixed dentition is not usually available on the NHS. Private orthodontic practices can offer early assessment and interceptive treatment for any child whose parents request it or where clinical findings support it. The cost of early interceptive treatment varies but is typically lower than comprehensive fixed brace treatment — often in the range of £500 to £2,000 depending on the appliance used. The IOTN checker can give you a preliminary sense of whether your child is likely to meet the NHS eligibility threshold when the time comes for full treatment. Consider booking an early assessment if you notice any of these Important Early orthodontic assessment is a clinical screening, not a sales process. A reputable specialist orthodontist will not recommend early treatment unless there is a clear clinical rationale — most children at age seven will be placed on a monitoring programme rather than started immediately. If an early assessment recommends treatment for a child younger than nine to ten, asking clearly what the specific clinical benefit of acting now versus waiting is a completely reasonable question. The answer should be specific and evidence-based, not vague.
