Kids Orthodontist: When Should Your Child Have an Assessment?

As a parent, it is entirely natural to notice changes in how your child's teeth are growing and to wonder whether everything is developing as it should. Perhaps their adult teeth have come through slightly crooked, or their top and bottom teeth do not seem to meet in quite the right way. You might be wondering whether these things matter, or whether it is simply part of how teeth develop.

Seeing a kids orthodontist — or more accurately, a children's orthodontist — is not necessarily about starting treatment immediately. For many families, the first step is simply an assessment to understand how dental development is progressing and whether anything warrants closer attention.

This guide explains when an orthodontic assessment may be worth considering, what signs parents might notice, and what the process typically involves.

When Is an Early Orthodontic Assessment Useful?

The British Orthodontic Society suggests that some children may benefit from an orthodontic assessment from around the age of seven, particularly where specific concerns about jaw development or bite relationships are present. However, an early assessment does not mean early treatment is needed. Many children are simply monitored as their teeth continue to develop, and appropriate treatment — where required — often begins once more permanent teeth have come through.

---

What Does a Children's Orthodontist Do?

An orthodontist is a dental specialist who has completed additional postgraduate training, registered with the General Dental Council (GDC), specifically in the assessment and management of tooth alignment, bite relationships and jaw development. Their role goes beyond straightening teeth — they evaluate how the teeth, jaws and facial structures are developing together. For families with persistent bite concerns, a focused orthodontic bite assessment can help clarify whether monitoring or treatment timing is appropriate.

A paediatric orthodontist (or orthodontist seeing children and teenagers) will assess whether a child's dental development is following an expected pattern, identify any concerns that may benefit from monitoring or treatment, and advise families about suitable options at an appropriate time.

It is important to understand that orthodontists and paediatric dentists have distinct but complementary roles. A paediatric dentist focuses on children's general oral health — preventive care, managing dental decay, and supporting healthy development from early childhood. An orthodontist has specialist training specifically in bite and alignment. If your child's dentist notices developing concerns during routine check-ups, they may suggest a referral to an orthodontist for a more detailed assessment.

When Should a Child First See an Orthodontist?

There is no single answer that applies to every child. Dental development varies, and the right time for an orthodontic assessment depends on what, if anything, parents or the dentist have noticed.

The British Orthodontic Society (BOS) recommends that children with specific concerns — such as a developing crossbite, significant crowding, jaw discrepancies or unusual eruption patterns — may be worth assessing from around age seven. This is because, by this stage, the first permanent molars and incisors have typically begun to emerge, allowing an orthodontist to begin evaluating bite and jaw relationships more meaningfully.

However, this does not mean every child needs to visit an orthodontist at seven. For many children, dental development progresses without issue, and their regular dentist is well-placed to monitor things during routine appointments. An orthodontic assessment becomes more relevant when specific concerns arise, either identified by a dental professional or noticed by parents at home.

The key distinction is this: an assessment helps clarify what is happening and what, if anything, may need to happen next. It does not automatically lead to treatment.

Signs Your Child May Benefit from an Orthodontic Assessment

Certain observations may make an orthodontic assessment worth arranging. These are signs that could suggest developing alignment or bite concerns — not diagnoses. Some of these variations are part of normal dental development, and only a qualified professional can determine whether intervention is appropriate. Parents who notice persistent chewing or bite changes may also relate these patterns to subtle bite pattern changes discussed in broader orthodontic symptom education.

Signs that may warrant a conversation with your child's dentist or an orthodontist include:

• Crowded or overlapping teeth that do not appear to have enough space to emerge straight
• Noticeable gaps between teeth that seem wider than expected
• Upper front teeth that protrude significantly beyond the lower teeth
• Lower teeth that sit in front of upper teeth when biting (underbite)
• Upper and lower teeth not meeting evenly when the mouth closes (crossbite)
• A gap between front teeth when the back teeth are together (open bite)
• Difficulty biting or chewing food comfortably
• Adult teeth erupting in unusual positions or appearing blocked
• Baby teeth lost unusually early or late
• Jaw clicking, discomfort or asymmetry that the child mentions
• Persistent oral habits, such as thumb sucking, beyond the age of four or five

It is worth repeating: noticing one of these signs does not mean your child needs braces. It means that a professional assessment may help you understand whether the development is within normal range or whether closer monitoring would be sensible.

Common Orthodontic Problems in Young Children

Children's teeth change considerably between the ages of roughly five and thirteen as baby teeth are gradually replaced by permanent ones. During this mixed dentition phase — when both baby and adult teeth are present — it is common to see teeth that look uneven or spaced.

Some of the more common orthodontic concerns that may become apparent during childhood include:

• Crowding — insufficient space for adult teeth to emerge in alignment
• Spacing — gaps between teeth that persist beyond expected developmental stages
• Overbite — upper front teeth covering a large portion of the lower front teeth vertically
• Overjet — upper front teeth protruding horizontally beyond the lower teeth
• Underbite — lower teeth sitting in front of upper teeth
• Crossbite — one or more upper teeth sitting inside the lower teeth
• Open bite — a gap between the biting edges of the front teeth when the back teeth are together

Not all of these concerns require immediate treatment. Some may naturally improve as the dentition develops. An orthodontist is best placed to advise whether monitoring or early intervention is appropriate for a specific child.

---

What Is Early Interceptive Orthodontics?

Early interceptive orthodontics refers to treatment that is considered while a child still has some baby teeth, or during the early stages of the permanent dentition, with the aim of addressing specific developing concerns at a stage when the jaw and teeth are still growing.

The goal is not to complete all orthodontic treatment early. Rather, it is to address particular problems — such as a developing crossbite or a significant jaw discrepancy — at a time when intervention may work with the natural growth process.

Potential situations where early treatment may be considered include:

• Certain crossbites that may become more difficult to manage if left until all permanent teeth have emerged
• Significant jaw discrepancies that may benefit from guidance during growth
• Specific space management concerns following early loss of baby teeth
• Habits or structural factors affecting developing tooth positions

It is important to note that early interceptive treatment does not eliminate the possibility of further orthodontic treatment later. Many children who have early treatment still benefit from a second phase of comprehensive orthodontic care in their teenage years. Whether early treatment is appropriate depends entirely on the specific clinical findings and the individual child's development.

Types of Braces and Appliances for Children and Teenagers

Where orthodontic treatment is recommended, there are several types of appliances that may be suitable, depending on the nature of the orthodontic problem, the child's age and dental maturity, and their ability to cooperate with treatment.

No single appliance is suitable for all children. An orthodontist will assess what is clinically appropriate based on individual circumstances. Families often find it useful to plan school meals and routines around eating with fixed braces when a fixed appliance is recommended.

---

Can Children Use Clear Aligners Instead of Braces?

Clear aligners — removable, transparent trays that gradually guide teeth into better alignment — are available for some younger patients, though their suitability depends on several factors.

For clear aligners to be effective, the child generally needs to have sufficient permanent teeth in place, the motivation and maturity to wear the aligners for the recommended period each day (typically around twenty-two hours), and the ability to maintain good oral hygiene around the appliances. Aligners that are not worn consistently are unlikely to achieve the intended result.

For younger children or those with complex orthodontic needs, fixed braces may be a more clinically appropriate choice. Clear aligners are not automatically superior to fixed braces — the most suitable option depends on the individual's orthodontic needs, dental development and ability to follow the treatment instructions. Your orthodontist will discuss which options may be suitable for your child after a thorough assessment.

---

When Might a Palate Expander Be Considered?

A palate expander is an orthodontic appliance designed to widen the upper jaw (maxilla) by gradually applying gentle pressure. It is not a routine part of every child's orthodontic treatment — it is considered in specific situations where the upper jaw is narrower than the lower jaw, contributing to a crossbite or other structural concern.

Palate expansion is generally considered during the growing years, while the mid-palatal suture — the growth plate at the centre of the upper jaw — remains sufficiently responsive. An orthodontist will assess whether expansion is appropriate and, if so, which type of expansion appliance is suitable.

It is important to understand that not every child with crowded or slightly narrow-looking upper teeth needs a palate expander. Only a clinical examination can determine whether expansion is indicated.

---

Can Thumb Sucking Affect Tooth Alignment?

Thumb sucking is a very common and entirely normal habit in infancy and early childhood. Most children naturally stop the habit between the ages of two and four. For children who continue thumb sucking beyond this age — particularly with significant frequency or intensity — there is a possibility that the habit may influence the developing position of the teeth and the bite relationship.

Potential effects of prolonged thumb sucking on dental development may include changes to the position of the upper front teeth, an open bite (a gap between front teeth when the back teeth meet), or effects on the upper jaw shape. The significance of the habit depends on factors including how long it continues, how frequently it occurs and how intensely the child sucks.

Parents should not feel that their child's dental future is determined by an early childhood habit. If thumb sucking persists beyond primary school age and you have concerns, raising it with your child's dentist is a sensible step. Sensitive, age-appropriate support tends to be more effective than pressure.

What Happens During a Child's First Orthodontic Consultation?

For many families, the idea of a first orthodontic appointment can feel uncertain. In practice, an initial consultation is typically a discussion and assessment, rather than the start of treatment.

The appointment usually involves:

• A conversation about your child's dental history and any concerns you or your child's dentist have noticed
• A clinical examination of tooth alignment, bite relationship and jaw development
• Discussion of any oral habits that may be relevant
• Consideration of whether further records — such as dental photographs, digital scans or X-rays — are clinically appropriate

Following the assessment, the orthodontist will explain their findings. The outcome may be one of several things: reassurance that development is progressing normally, a recommendation to monitor at future appointments, a discussion of early treatment options, or advice to return at a later stage when more permanent teeth have emerged. If parents want clarity on clinician backgrounds before deciding next steps, reviewing the multidisciplinary dental team can support informed consent conversations.

A first consultation does not automatically result in a recommendation for braces. The first appointment is about understanding where your child's dental development is — and deciding together what, if anything, should happen next.

How to Prepare Your Child for Their First Orthodontist Visit

Helping your child feel comfortable before their first orthodontic appointment can make a meaningful difference. Some practical ways to prepare include:

• Explain the appointment simply — describe it as a check-up for their teeth and jaw, not as something that involves pain
• Answer questions honestly — if your child asks what will happen, explain that the orthodontist will look at their teeth and talk to you both about how they are growing
• Encourage your child to ask questions — letting them feel involved can reduce anxiety
• Avoid negative framing — try not to describe orthodontic appointments as something to be worried about
• Bring relevant information — if your child's dentist has shared any notes or X-rays, bring these along
• Mention any habits — let the orthodontist know about thumb sucking, mouth breathing or other habits your child has had

The tone you set before the appointment can influence how your child feels during and after it. Keeping your language calm and positive tends to help.

How Long Do Children Usually Wear Braces?

The duration of orthodontic treatment varies considerably between children and depends on several factors, including:

• The nature and complexity of the orthodontic concern
• The type of appliance being used
• The child's stage of dental development at the start of treatment
• How consistently the child follows the instructions (particularly important for removable appliances and aligners)
• Attendance at review appointments
• The child's response to orthodontic forces
• Oral health during treatment

As a general indication, comprehensive fixed-brace treatment in teenagers often lasts between twelve and twenty-four months, though some cases may be shorter or longer. Early interceptive treatment may be shorter and more targeted. These are estimates — no treatment duration can be guaranteed at the outset.

After active orthodontic treatment, retainers are typically recommended to help maintain the position of the teeth. Retainers are an important part of the overall orthodontic process and may need to be worn long term.

---

Helping Your Child Manage Discomfort During Orthodontic Treatment

It is common for teeth to feel tender for a few days after braces are fitted or adjusted. This is a normal response to the pressure being applied, and it typically settles within a few days.

Practical ways to help your child during adjustment periods include:

• Offering softer foods — such as pasta, soup, yoghurt and mashed vegetables — when teeth feel sensitive
• Encouraging gentle but thorough brushing and interdental cleaning to maintain good oral hygiene
• Using orthodontic wax to protect the inside of the cheeks or lips from irritation if a bracket or wire rubs
• Following any guidance provided by the orthodontic team
• Contacting the orthodontic practice promptly if a wire or appliance causes injury, significant discomfort or breaks

For pain management, parents should follow appropriate age-specific pharmacist or healthcare professional guidance. Persistent or unusual discomfort that does not settle should always be reported to the orthodontic practice. Ongoing home care habits described in paediatric dental prevention routines can also make adjustment periods easier for children.

NHS and Private Orthodontic Treatment: What Parents Should Know

NHS Orthodontic Treatment

NHS orthodontic treatment for children is available based on clinical need, assessed using the Index of Orthodontic Treatment Need (IOTN). This is a scoring system used to grade the severity of orthodontic concerns and determine whether NHS-funded treatment is appropriate. Children who meet the clinical threshold may be eligible for NHS treatment, which is provided free of charge for those under eighteen.

Cosmetic preference alone — for example, wanting slightly straighter teeth that are otherwise clinically healthy — does not establish eligibility for NHS orthodontic treatment. Assessment for NHS eligibility is carried out by appropriately trained dental professionals.

Waiting times for NHS orthodontic treatment can vary between regions. Your child's dentist can advise whether referral to an NHS orthodontic service is appropriate.

Private Orthodontic Treatment

Where children do not meet the NHS eligibility threshold, or where parents prefer to arrange treatment privately, fees will vary depending on:

• The type of appliance recommended
• The complexity of the orthodontic problem
• The duration of treatment
• Whether records, retainers and follow-up appointments are included in the quoted fee

It is important to clarify exactly what is included in any private orthodontic quotation before treatment begins. Private orthodontic treatment is not automatically more clinically effective than NHS care — clinical suitability should guide treatment decisions, not cost alone.

Parents considering orthodontic treatment costs should ask the practice to provide a clear written treatment plan and cost estimate before committing.

A Note on Informed Decision-Making

Whether you have noticed something about your child's teeth that concerns you, or whether your dentist has suggested an orthodontic review, the most important step is to seek an appropriate professional assessment. That assessment will give you a clearer picture of what is happening and what, if anything, would be helpful.

Not every child will need orthodontic treatment. Many families find that an assessment provides reassurance that their child's development is progressing as expected. Where concerns do exist, understanding them early gives families the opportunity to make informed decisions about monitoring, timing and the most appropriate way forward.

If you have questions about your child's dental development, starting with your regular dentist is always a reasonable first step.

Frequently Asked Questions

Can a child have an orthodontic assessment while they still have baby teeth?

Yes. In some cases — particularly where there are concerns about jaw development, crossbite or unusual eruption patterns — an early orthodontic assessment while baby teeth are still present can be informative. An assessment at this stage does not mean treatment will begin immediately. The orthodontist may recommend monitoring and review at a later stage when more permanent teeth have come through.

Should parents mention a family history of orthodontic problems at the consultation?

Yes, it is worth mentioning. While a family history of crowding, prominent teeth or bite concerns does not guarantee that a child will experience the same issues, it can be relevant context for the orthodontist. Genetic factors can influence jaw size, tooth size and the relationship between the two. Sharing this background helps the orthodontist consider the fuller picture.

Can children play sports while wearing braces?

In most cases, yes — though a mouthguard is strongly recommended for contact sports. Standard-issue mouthguards may not fit well over fixed braces, so parents should ask their child's dental team about a suitable option. Removable orthodontic appliances and aligners should be removed before contact sports, following professional advice about storage and hygiene.

Can braces affect how a child speaks?

It is not uncommon for children to notice a slight change to their speech when they first receive a new orthodontic appliance, particularly removable ones. This typically resolves within days to weeks as the child adjusts. If speech difficulties persist or are significant, the orthodontic team should be informed.

What happens if a child loses a baby tooth earlier than expected?

Early loss of a baby tooth — whether through decay, injury or other causes — can sometimes allow neighbouring teeth to drift into the space, potentially reducing room for the emerging permanent tooth. A dentist may assess whether a space maintainer is appropriate. This is worth discussing with your child's dentist promptly if an early tooth loss occurs.

Can orthodontic appliances affect eating at school?

Children with fixed braces may need to avoid certain hard, sticky or chewy foods throughout treatment — such as hard crusty bread, toffees or chewing gum — that can damage brackets or wires. School packed lunches can usually be adapted with softer options. Children with removable appliances will typically remove them during meals, which can initially feel unfamiliar but tends to become routine quickly.

What should parents do if a child breaks an orthodontic appliance?

Contact the orthodontic practice as soon as possible to explain what has happened and arrange an appointment. If a wire is causing discomfort or injury to the mouth before an appointment is available, a small piece of orthodontic wax can provide temporary protection. Do not attempt to repair appliances at home. Broken appliances can slow treatment progress and should be attended to promptly.

Can children continue playing musical instruments while wearing braces?

Many children do continue to play instruments during orthodontic treatment, though there may be an adjustment period — particularly for wind or brass instrument players who rely on the position of their lips against their teeth. Most children adapt over time. If a child plays a wind or brass instrument, it is worth mentioning this at the initial consultation so the team can offer appropriate guidance.

How often will a child need review appointments during orthodontic treatment?

The frequency of review appointments depends on the type of appliance and the stage of treatment, but appointments are commonly arranged every six to ten weeks during active fixed-brace treatment. Missing appointments can slow progress and should be rescheduled promptly. The orthodontic team will advise on what is appropriate for your child's treatment plan.

What happens if a child is not ready to cooperate with treatment?

Orthodontic treatment — particularly removable appliances and clear aligners — depends significantly on patient cooperation. If a child is not emotionally or practically ready to manage the demands of treatment, an experienced orthodontist will often recommend waiting rather than beginning treatment prematurely. Starting at the right time, when the child is motivated and able to care for the appliance, generally leads to better outcomes.
