• When to refer a child for tongue tie assessment

    August 1st, 2026 | by

    For midwives, lactation consultants, GPs, paediatricians, speech pathologists, occupational therapists, dentists and orofacial myofunctional therapists.

    Tongue dysfunction does not stay in one form. It changes with age and with demand, and it often becomes less visible over time — not because the problem has resolved, but because the child has found another way to cope.

    That is the question worth holding onto: when a child appears to be coping, has function improved, or has compensation simply become more effective?

    Each discipline sees a different part of the same child. A midwife sees the first feed. A lactation consultant sees transfer, pain and supply. A paediatrician sees growth, sleep and milestones. A speech pathologist sees articulation and whether therapy is progressing. A dentist sees oral posture, arch form and function over time. Individually those signs are easy to explain away. Together they often tell a clearer story.

    The referral framework: three domains, three concerns

    You do not need diagnostic certainty to refer. You need a cluster.

    Domain 1 — Appearance. What you can see. A heart-shaped or notched tip, a visible web, limited free tongue, attachment close to the tip or the gum ridge.

    Domain 2 — Function. What you can assess. Can the child elevate with the mouth less than half open? Can they lateralise to both sides? Can they touch the spot behind the upper incisors?

    Domain 3 — Parent report. What the family is telling you. Feeding difficulty, clicking, maternal nipple pain, slow progress with solids, speech concerns, drooling.

    Three or more concerns across any combination of these domains warrants referral for a full functional assessment.

    Two myths that delay referral

    “The grade tells you how severe it is.” It does not. Anatomical grade does not equal functional severity. A small anterior tie can cause complete breastfeeding failure; a higher-grade posterior tie may have minimal impact in another child. Anatomy tells you what is there; function tells you whether it matters.

    “If the child can stick their tongue out, it isn’t a tie.” This is the most damaging misconception in the field. Protrusion is among the least functionally relevant movements. Elevation — mid-posterior rise to create vacuum — is what feeding depends on, and it is independent of protrusion.

    What you feel, not what you see

    Anterior ties are visible and straightforward to identify on inspection. Posterior and submucosal restrictions are a different matter — extension may be normal, the tongue may look unremarkable, and it is elevation that is restricted.

    The frenulum is not a simple midline string. Histological work published by Mills, Pransky, Geddes and colleagues in Clinical Anatomy (2019) describes it as a fascial diaphragm — a broad midline fold that inserts around the inner arc of the mandible — rather than a simple string under the tongue. Because it is fascial rather than purely mucosal, composition varies widely, and visual inspection can look entirely normal while palpation reveals significant restriction.

    A tight band on palpation that is invisible on inspection is a posterior tie. If you are not palpating the floor of the mouth, the assessment is not complete.

    What to look for, by window

    Birth to six weeks — midwives, IBCLCs, GPs. Clicking, dribbling, poor or slipping latch, very long feeds, poor transfer. On the maternal side: nipple pain and damage, a compressed or distorted nipple shape after feeds, blanching, falling supply. Nipple compression and blanching is a high-specificity sign — it suggests the tongue has compensated by clamping because it could not generate negative pressure. The mother is part of the clinical picture, not separate from it.

    The six and eight week check — GPs, paediatricians. This is the most commonly missed window, because by now the feeding crisis has often resolved onto formula and every metric looks reassuring. Weight gain on formula does not rule out a restriction; it removes the symptom everyone was watching. The tongue has not changed.

    Six months to two years — GPs, paediatricians, IBCLCs. Gagging across textures, restriction to purees, drooling, disrupted sleep. A tongue that cannot lateralise cannot move food to the molars or form a bolus. “Fussy eater” and “texture aversion” are not personality traits — they are frequently oral motor signs, and they earn a look.

    Two to five years — speech pathologists, paediatricians. Articulation errors involving sounds that require precise tongue-tip placement and elevation. Where progress on these plateaus despite months of targeted therapy, that is a flag to assess tongue movement rather than intensify the drill. Watch for jaw substitution and lip recruitment developing as compensatory strategies.

    This window is also the most clinically awkward: often too old for a simple in-room release, and too young to cooperate with awake functional release and active post-operative rehabilitation. That is an argument for active myofunctional and feeding support during this period, not for doing nothing.

    School age and adolescence — GPs, paediatricians, school health, dentists. Mouth breathing and open-mouth resting posture, snoring or restless sleep, a high or narrow palate, persisting speech errors, dental crowding and early orthodontic concern. Where orthodontic treatment is being planned, tongue posture is worth considering alongside it rather than instead of it.

    Compensation versus adaptation

    This distinction is worth holding across disciplines.

    Adaptation means the tongue genuinely gains function — the underlying problem is addressed.

    Compensation means the jaw, lips and cheeks take over to mask the restriction. It looks like coping, but the pattern hardens, becomes learned, and becomes the child’s only available strategy.

    Every month of compensation is a month of entrenched motor pattern that later therapy or post-surgical rehabilitation has to unpick.

    It is not always a tongue tie

    Anything that prevents the tongue resting on the palate can produce a similar picture: mouth breathing secondary to adenoid hypertrophy, chronic nasal obstruction, allergic rhinitis, low muscle tone, structural palate differences, neurological differences.

    A child mouth breathing because of adenoids needs an ENT opinion, not a frenectomy. Part of the value of a functional assessment is distinguishing what is actually driving the dysfunction — and saying so when a tie is not the answer.

    A note on lip ties

    Lip ties are approached conservatively. There is currently no evidence that releasing a lip tie in infancy prevents diastema, and they are not released routinely.

    Lip ties are assessed in consultation with the allied health professional involved in the child’s care rather than in isolation — commonly an IBCLC for an infant, and a myofunctional therapist or speech pathologist for an older child, either of whom may be the first to raise the concern. If you are supporting a child where lip function looks restricted, that observation is exactly what we want to see in a referral. Appearance alone is not a basis for assessment or treatment.

    What happens when you refer

    A referral letter from any GP or allied health discipline is all that is needed; families can also book directly. Assessment includes history, functional examination with palpation, validated measures of tongue range of motion and, where indicated, validated screening for sleep-disordered breathing, plus feeding observation where relevant.

    Where treatment is indicated, the plan is therapy before, release, therapy after — a release alone does not restore function. Where treatment is not indicated, we say so.

    You will receive written communication on findings and the proposed plan, and again after any treatment. We aim to keep you involved rather than take over the child’s care.

    Assessments are with Dr Helen Fung. The team will arrange a suitable appointment time with the family.

    A note on clinical discernment

    The evidence base in this field is uneven, enthusiasm has in places outrun data, and surgical rates in some communities are difficult to justify. Healthy scepticism is a prerequisite for good diagnosis, not an obstacle to it.

    Equally, inaction is not neutral. Where a functional problem is present, watching and waiting without support is itself a choice with consequences — for the baby, for the mother and for the family.

    The aim is functionally driven assessment, conservative decision-making, multidisciplinary support and honest conversations with families.

    One action, whatever your discipline

    Midwives and IBCLCs: palpate the floor of the mouth. Every painful or clicking feed earns a feel, not just a look.

    GPs and paediatricians: weight gain is not a tongue examination. Look anyway, at every developmental check.

    Speech pathologists: where progress on tongue-tip and elevation sounds has plateaued despite months of targeted work, assess tongue movement.

    Dentists and myofunctional therapists: read the palate and the airway. A narrow arch in a mouth breather is a tongue posture story as well as an orthodontic one.

    Everyone: three or more concerns across appearance, function or parent report — refer. You do not need certainty. You need a cluster.

  • Why having a consistent “dental home” matters for your child

    July 25th, 2026 | by

    If you’ve ever filled out the same new-patient form at three different clinics, or found yourself explaining your child’s dental anxiety to a new dentist every single visit, you already understand the problem a “dental home” solves. A dental home simply means having one consistent practice — and, where possible, familiar faces within it — who get to know your child over time, rather than moving between different practices or fitting in a check-up wherever happens to be convenient. It might sound like a small thing, but for many families it makes a real difference to how comfortable, coordinated and reassuring dental visits feel.

    What we mean by a “dental home”

    A dental home isn’t a building — it’s a relationship. It’s the idea that your child has one trusted paediatric dental practice that holds their full picture: their dental history, their habits, what has worked to help them feel calm in the chair, and any conditions or concerns that need ongoing attention.

    At Tooth Town, that means your child’s records, history and preferences stay with our team, and our broader group of specialist paediatric dentists, general dentists and allied health professionals can all draw on the same understanding of your child as they grow. It’s a different experience to starting fresh at a new practice each time, where the team is meeting your child — and learning about them — for the very first time, every time.

    The team gets to know your child, not just their teeth

    When your child sees a familiar practice over time, our team builds a genuine picture of them — not only what their teeth look like, but how they respond to new experiences, what helps them feel settled, and what their dental journey has looked like so far. That might include things like:

    • Which techniques have helped them cope with anxiety in the past
    • Whether they’ve had fillings, extractions or other treatment before, and how they went
    • Habits like thumb-sucking or teeth grinding that are worth keeping an eye on
    • Any medical history that’s relevant to their dental care

    Instead of re-explaining all of this at every visit, that history is already part of your child’s story with us. It means appointments can focus on your child, rather than on paperwork and background.

    Small changes are easier to notice over time

    Children’s mouths change quickly — new teeth arrive, old ones fall out, jaws grow, and habits shift. When the same practice is tracking your child’s development visit to visit, small changes are often easier to notice early, simply because there’s a consistent point of comparison. A practice seeing your child for the first time doesn’t have that same history to compare against.

    This doesn’t mean every issue can be predicted or prevented — dental development varies, and some things only become clear on the day. But continuity of care gives our team a helpful head start in understanding what’s typical for your child specifically.

    Familiar faces can make visits easier

    For many children, especially those who feel anxious about the dentist, familiarity matters. Recognising the practice, the waiting room, and — where rostering allows — a familiar dentist or team member can genuinely help a child feel calmer and more willing to cooperate. Trust tends to build gradually, visit by visit, and that trust can make future appointments smoother for everyone.

    We do our best to support continuity where possible, but please note that clinician availability and appointment types can mean your child sees different members of our team from visit to visit. Whoever your child sees, they’ll have access to the same history and notes, so care stays joined up even if the face in the room varies.

    Better coordination for specialist needs

    One of the quiet benefits of a dental home is coordination. All of the general dentists consulting at Tooth Town are well versed in screening for tongue and lip tie, early orthodontic and airway-related concerns as part of routine check-ups, so a referral typically starts from something noticed at a regular visit, rather than being a separate process you need to initiate yourself. If your child needs a referral within our practice for something more specific — for example, a tongue or lip tie assessment with Dr Helen Fung, an early interceptive orthodontic review, or special needs dental care with Dr Candy Fung — that referral happens within a team who are already working from the same picture of your child’s care, rather than starting from a blank slate.

    This can make transitions between general check-ups and more specific care feel smoother, with less repetition and fewer gaps in communication.

    It’s never too late to start

    If your family has moved between practices before, or your child hasn’t had consistent dental care until now, please don’t feel there’s anything to catch up on or apologise for. Families change dentists for all sorts of reasons — moving suburbs, changing circumstances, or simply not having found the right fit yet. Tooth Town welcomes new patients at any age or stage, and our team will take the time to properly understand your child’s history and needs at their first visit, so we can build that dental home from here.

    Frequently asked questions

    Will my child always see the exact same dentist at Tooth Town?

    We aim to support continuity where possible, but rostering and appointment type can mean your child sees different members of our team across visits. Whoever they see will have access to the same notes and history, so care stays consistent even when the clinician varies.

    What if we’ve been to a few different dental practices before?

    That’s completely fine. At your child’s first Tooth Town appointment, our team will take the time to understand their history, any previous treatment, and how they typically respond to dental visits, so we can start building a clear picture from that point forward.

    Does a dental home mean my child will need fewer check-ups?

    Not necessarily — a dental home is about consistency and continuity of care, not the frequency of visits. Your child’s clinician will confirm an appropriate check-up schedule based on their individual needs.

    How does this help if my child needs to see a specialist, like for a tongue tie or orthodontics?

    Because all of the general dentists consulting at Tooth Town are well versed in screening for these kinds of concerns as part of routine check-ups, and our team shares the same understanding of your child’s history, a referral within Tooth Town — for example to Dr Helen Fung for tongue and lip tie assessment, our orthodontic care pathway, or Dr Candy Fung for special needs care — can happen with more context already in place, which may help make that transition feel smoother.

    Is Tooth Town suitable if my child has additional needs or anxiety around dental visits?

    Yes. Building familiarity and trust over time is one of the key benefits of a dental home, and it can be particularly helpful for children who feel anxious or who benefit from a predictable, understanding team. Please let us know about any specific needs so we can support your child appropriately.

    What if we need to change practices again in the future?

    We understand that circumstances change. If that happens, your child’s records can be transferred to support continuity of care with their new provider.

    What to do next

    If your family is looking for a consistent dental home for your child — whether you’re new to Tooth Town or have moved between practices before — we’d love to meet you. Book an appointment and our team will take the time to get to know your child properly, so we can start building that ongoing picture of their care together.

    This guide is general information and doesn’t replace an individual assessment. Your child’s clinician will confirm what’s most appropriate for them after examination.

  • Dental X-rays for children: what to expect and why they’re needed

    July 25th, 2026 | by

    If your child’s clinician has mentioned they’d like to take an X-ray, it’s natural to have questions — why it’s needed, whether it’s safe, and what the appointment will actually involve. Dental X-rays are a routine, well-established part of paediatric dental care, and they’re only ever taken when they’ll genuinely help your child’s clinician understand what’s going on. This guide explains why X-rays are sometimes needed, how we keep radiation exposure low and the experience comfortable, and what to expect on the day.

    Why X-rays are sometimes needed

    Some things about your child’s teeth simply can’t be seen with the eye alone — such as decay developing between teeth, how an adult tooth is positioned before it comes through, or the roots of a tooth beneath the gum. An X-ray gives your child’s clinician a clearer picture in these situations, which helps them make well-informed recommendations about your child’s care.

    X-rays aren’t taken as a routine formality at every visit. Your child’s clinician will only recommend one where there’s a genuine clinical reason to, based on what they’ve found during an examination and your child’s individual needs.

    Keeping radiation exposure low

    It’s a completely reasonable thing to wonder about, and we want to be upfront: a dental X-ray involves a genuinely small amount of radiation. To put it in context, everyday life already involves a certain amount of background radiation exposure — from things like a flight, ordinary sunlight, and even naturally occurring radiation in foods like bananas. A dental X-ray sits in a similar territory, and our equipment and technique are chosen specifically to keep the amount used as low as reasonably possible while still giving your child’s clinician a clear, useful image. We also only take an X-ray where there’s a genuine clinical reason to, rather than as routine.

    Keeping X-rays comfortable for your child

    We know that a new piece of equipment near their face can feel a little unfamiliar for a child, so our team takes things gently and explains each step in simple, friendly language before it happens. Please let us know beforehand if your child has particular sensitivities or has found dental visits difficult in the past, so we can plan the appointment around them.

    Part of the complete picture

    An X-ray is one part of how we get to know your child’s teeth — it doesn’t replace a regular clinical examination, and a clinical examination doesn’t replace an X-ray when one is genuinely needed. Together, they help your child’s clinician see the full picture and make well-informed recommendations about their care.

    Frequently asked questions

    How often will my child need a dental X-ray?

    There’s no fixed schedule that applies to every child. Your child’s clinician will recommend an X-ray only when there’s a clinical reason to, based on their examination and your child’s individual needs.

    Is dental X-ray radiation dangerous for children?

    A dental X-ray involves a genuinely small amount of radiation — comparable to the everyday background radiation exposure most of us already experience through things like flying, sunlight, or naturally occurring radiation in some foods. Our equipment and technique are chosen to keep the amount used as low as reasonably possible, and your child’s clinician will only recommend an X-ray when the benefit to their care outweighs this small exposure.

    What if my child won’t sit still or bite down on the sensor?

    That’s okay — our team is used to working with children who feel unsure or find it hard to stay still. We’ll take things at your child’s pace and use child-friendly techniques to help. If an X-ray genuinely can’t be taken on the day, your clinician will discuss the best way forward with you.

    Can I stay with my child during the X-ray?

    You’re welcome to stay with your child for their appointment, including while the X-ray is being taken. The one practical difference with X-rays is that, for the brief moment the image itself is captured, our team may ask you to step just outside the room or stand at a short distance, since this is a routine, standard part of how radiation exposure is kept low for anyone remaining nearby — you’ll be straight back with your child immediately afterwards. This is a routine radiation safety step, not a general restriction on staying with your child, and it’s separate from Tooth Town’s general anaesthesia policy, where parental presence isn’t possible in the hospital operating theatre, in line with national standards. Please ask our team on the day if you’d like this explained further.

    Will an X-ray tell us if my child has a cavity?

    An X-ray can help show decay that isn’t visible to the eye, particularly between the teeth. It’s one part of the assessment — your child’s clinician will use both the examination and the X-ray together to explain what they’ve found and what, if anything, is recommended next.

    What to do next

    If your child’s clinician has recommended an X-ray, or you’d simply like to understand more about what to expect at their next visit, our team is happy to talk it through with you. Book an appointment and we’ll take good care of your child, at their pace, every step of the way.

    This guide is general information and doesn’t replace an individual assessment. Your child’s clinician will confirm what’s most appropriate for them after examination.
