If feeding is painful, or taking forever, or your baby seems to be working hard and getting little, you have probably already been given a lot of advice. Some of it will have been about positioning. Some about supply. Some about persistence.

This page is about a different question: whether your baby’s tongue can physically do what feeding requires.

What the tongue has to do

Breastfeeding depends on the tongue being able to extend, elevate, cup, move side to side, spread and control a swallow. Restriction of any one of those can affect a feed.

The one that matters most, and gets checked least, is elevation — lifting the mid and back of the tongue to the palate to create suction. A baby who cannot elevate cannot generate the vacuum a feed depends on, no matter how good the positioning is.

Sticking the tongue out is not on that list, and it is not a useful test. Plenty of babies with significant restriction can poke their tongue out perfectly well.

Signs parents notice in the baby

Clicking during feeds can suggest the seal is breaking and air is getting in. Milk escaping at the corners of the mouth points the same way. A baby who repeatedly slips off, or who feeds for a very long time and still seems unsatisfied, may be struggling to hold and maintain the latch.

Very long feeds and poor weight gain often travel together, and that pairing is worth taking seriously.

None of these signs confirms a tongue tie on its own. Each has other possible causes. What they do justify is a proper look — a functional assessment rather than guesswork.

Your symptoms are clinical information too

This is the part that often gets missed, and it matters.

If you are in pain, that is not just context for your baby’s assessment. It is diagnostic information in its own right.

Nipple pain and damage, and particularly a nipple that comes out compressed, blanched or distorted in shape after a feed, is one of the most telling signs there is. A misshapen or lipstick-shaped nipple suggests the tongue has been clamping to compensate, because it could not create suction the normal way.

Falling supply and sheer exhaustion belong in the picture too. You are not simply the reporter of your baby’s symptoms — what your body is telling you is part of the assessment.

If feeding stopped, that was not a failure

Many parents arrive having stopped breastfeeding weeks or months earlier, carrying a sense that they did not try hard enough.

Stopping is rarely about wanting to. It is usually about pain, exhaustion, and not having found the cause in time. If a tongue could not do its job, no amount of persistence would have changed the mechanics — and being told to keep trying was never going to fix it.

It is also worth knowing that a restriction can still be worth assessing after breastfeeding has ended. Which brings us to the next point.

Weight gain on formula does not rule anything out

Once a baby moves to a bottle, the feeding crisis usually settles. Weight goes up. Everyone relaxes. Every metric looks reassuring.

But moving to formula does not change the tongue. It removes the symptom that everyone was watching. The same restriction is still there, and the same tongue will meet solids in a few months, and speech after that.

So if feeding difficulties resolved by switching, and you have wondered since whether something was going on, that instinct is worth acting on rather than dismissing.

Bottle-fed babies can have difficulties too

Feeding problems are not exclusive to breastfeeding, and a bottle is not proof that everything is fine. Difficulty with the seal, milk escaping, long or tiring feeds and unsettledness after feeds can all occur with a bottle as well.

What an assessment involves

Assessment is by Dr Helen Fung, and it is a functional assessment rather than a look.

It starts with your history — the feeding, the pain, what has already been tried, and who else is involved. It includes examining what the tongue can actually do, and gentle palpation of the floor of the mouth, because some restrictions are simply not visible. A tongue can look completely normal on inspection while a tight band is easily felt.

Sometimes the most useful outcome is that no treatment is needed. Sometimes the next step is support from a lactation consultant, feeding specialist or myofunctional therapist rather than a procedure. Sometimes a release is appropriate — and if it is, it is only ever part of a plan that includes therapy before and after.

We work closely with lactation consultants, and if you already have one, please bring what they have observed. Their input is genuinely useful, and often shapes the plan.

If you are still feeding, do not wait until it is unbearable

There is no prize for enduring painful feeding. If it hurts, if feeds are taking most of your day, or if your baby is not gaining as expected, that is enough reason to have things looked at — even if the answer turns out to be that no procedure is needed.

Please seek prompt medical care if you are worried about your baby’s weight, hydration or general wellbeing.

Common questions

Does painful feeding always mean tongue tie?

No. Nipple pain has several possible causes, including positioning, latch, infection and other factors. A functional assessment helps work out whether restriction is contributing.

My baby is gaining weight — could there still be a tie?

Yes. Weight gain, particularly on formula, does not rule out a restriction. It removes the symptom that was most visible.

Can my baby have a tie if she can stick her tongue out?

Yes. Protrusion is one of the least functionally relevant movements. Elevation is what feeding depends on, and the two are independent.

Is it too late if we have already stopped breastfeeding?

No. Assessment is still worthwhile — the same tongue will meet solids and speech later on.

Do I need a referral?

No. Bring anything you have from your GP, lactation consultant, midwife or child health nurse.

A tongue tie assessment at Tooth Town is a functional assessment. That means it is not a quick look under the tongue — it is a careful examination of what your child’s tongue can actually do, alongside a proper conversation about what you have been noticing.

Assessments are carried out by Dr Helen Fung, a specialist paediatric dentist whose clinical focus is functional tongue assessment across infancy, childhood, adolescence and adulthood. You may also see this described as the Brisbane Tongue Tie Clinic.

First, we listen

The appointment starts with you. What have you noticed? What is the feeding like, or the eating, or the speech? How long has it been going on? Who else is involved — a lactation consultant, a speech pathologist, a GP, a child health nurse?

If your baby is feeding, what you are experiencing matters clinically too. Nipple pain and damage, a distorted or blanched nipple shape after feeds, feeds that stretch out very long, or supply concerns are all part of the picture — not just background information. You are not simply the reporter of your baby’s symptoms.

For older children, we want to know about eating and textures, speech and how therapy is progressing, and how your child sleeps and breathes.

Then we assess function, not just appearance

This is the part that differs most from a casual look.

The tongue needs to be able to do six things, and restriction of any one of them can matter:

Extend — reach forward far enough to grasp and stabilise.
Elevate — lift the mid and back of the tongue to the palate. This is the movement breastfeeding depends on, and the one most often missed.
Cup — hold and maintain a seal.
Lateralise — move side to side, which is what moves food to the molars.
Spread — spread out at the front for an effective latch.
Control — manage a swallow safely.

You will notice that sticking the tongue out is not on that list. Protrusion is the movement checked most often and it is one of the least functionally relevant. Elevation matters far more, and a child can have one without the other.

And we feel, not just look

Some restrictions are clearly visible. Others are not visible at all — the tongue can look entirely normal on inspection while a tight band is easily felt underneath.

That is why the assessment includes gentle palpation of the floor of the mouth. It is quick and well tolerated, and it is the part of the examination that finds what looking alone cannot. An assessment that does not include it is not complete.

We use validated tools

Where appropriate, we use recognised measures rather than relying on impression alone — including a validated measure of tongue range of motion, and, where sleep or breathing is part of the picture, a validated screening questionnaire.

The point of using them is that they give a number. That means we can explain findings to you clearly, track change over time, and communicate precisely with your GP, lactation consultant or speech pathologist rather than trading vague descriptions.

What the assessment might conclude

There are several honest outcomes, and only one of them is a procedure.

No treatment needed. For many families this is the answer, and it is a good one. If the tongue is doing its job, a visible frenulum is not a reason to intervene.

Support from someone else first, or instead. Depending on your child, we may suggest working with a lactation consultant, a feeding specialist, a speech pathologist, an orofacial myofunctional therapist, or an ENT specialist. Sometimes improving how the mouth is used makes a real difference on its own. Sometimes the driver is not the tongue at all.

Active monitoring. Keeping an eye on things, with support, is a legitimate plan.

A release, as part of a wider plan. Where a restriction is genuinely limiting function and releasing it is likely to help, we will talk it through fully.

If a release is recommended, it is never the whole plan

This is the principle we most want families to understand, particularly if you have arrived having read about tongue tie surgery online.

A release on its own does not restore function. The tongue has to learn to use the range of movement it has gained, and that does not happen automatically. So the plan is normally therapy before, the release itself, and therapy afterwards — in that order.

The work beforehand prepares the muscles and begins unpicking the patterns your child has developed to compensate. The work afterwards is where function is actually rebuilt. Skipping it risks losing the benefit.

On method: both scissors and laser techniques are used in this field, and no method has been shown to be superior to another. What determines the outcome is the skill of the operator and the aftercare. If you encounter marketing claiming one tool is inherently better, that is worth treating with some scepticism.

We will talk you through what a release involves so you can decide with a clear picture of it, and nothing needs to be decided on the spot.

Why acting at the right time matters

When a tongue cannot do something, children are remarkably good at finding another way. The jaw, lips and cheeks step in to compensate.

That is why a child can appear to be coping while the underlying restriction is unchanged — and it is worth asking whether function has genuinely improved, or whether compensation has simply become more effective. Compensating patterns become habits, and habits take longer to unpick later.

This is not a reason to rush into a procedure. It is a reason not to leave a real difficulty unsupported.

Function is looked at in every consultation, not just this one

You do not need to book a tongue tie assessment for someone to notice a problem.

Every consultation at Tooth Town looks at how your child’s mouth is working, not only at their teeth. All clinicians consulting at Tooth Town — including the general dentists — consider function as part of a routine visit, and will refer you through for a full functional assessment with Dr Helen Fung if something warrants a closer look.

So if your child comes in for a check-up and there is something worth investigating, you will hear about it. You do not have to spot it yourself, and you do not have to ask for it.

Practical things to know

You are welcome to stay with your baby or child for the whole appointment, including a release if one is recommended. The only Tooth Town appointments where a parent cannot stay are those under general anaesthesia, and a tongue or lip tie release in the rooms is not a general anaesthetic procedure.

There are quiet, comfortable rooms where you can feed in privacy, and toys for siblings.

No referral is needed to book, though anything you have from your GP, lactation consultant, speech pathologist or child health nurse is genuinely useful — please bring it.

Tongue and lip tie consultations are with Dr Helen Fung. This is a dedicated assessment pathway rather than a general check-up appointment — the team will find you a suitable time when you book.

Common questions

How long does the assessment take?

Long enough to take a proper history, assess function and talk through what we find. The team can tell you what to expect for your child’s appointment when you book.

Will it hurt my baby?

The assessment itself is gentle. Palpation of the floor of the mouth is quick and usually well tolerated, though some babies object to having their mouth examined at all, which is normal.

Will the release happen on the same day?

We cannot promise that. The consultation is an assessment first. If treatment is appropriate, Dr Helen will discuss timing with you.

Do we need a referral?

No. You are welcome to bring information from other professionals involved, but a referral is not required to book.

What ages do you assess?

Babies, toddlers, older children, adolescents and adults. Feeding concerns in newborns, and eating, speech or oral function questions later on, are all reasons families come.

No. Many tongue ties never cause a problem and need no treatment at all.

If you have been told your baby or child has a tongue tie, that single sentence is probably the most useful thing you can know. A tongue tie is not automatically a problem to be fixed. It is a piece of anatomy that may or may not be affecting how your child’s mouth actually works — and the only way to know is a proper functional assessment.

Everyone has a frenulum

The small band of tissue under the tongue is called a frenulum, and every single person has one. You can feel your own with your tongue right now. It is normal anatomy, not a defect.

What matters is not whether the frenulum exists, or even how it looks. What matters is whether it restricts function.

Appearance does not predict function

This is the principle that guides every assessment at Tooth Town, and it is worth stating plainly because so much advice online does the opposite.

You cannot tell from looking whether a tongue tie matters. Two children can have frenulums that look almost identical, and one may be feeding beautifully while the other cannot latch. Equally, a restriction that barely shows on inspection can significantly limit how the tongue moves.

A related point: the grade or classification of a tie does not tell you how severe its effect will be. Anatomy tells you what is there. Function tells you whether it matters.

The myth that causes the most confusion

If you take one thing from this page, make it this one.

“If she can stick her tongue out, it’s not a tie” is not true.

Poking the tongue out past the lips — protrusion — is the movement people check most often, and it is one of the least important. The movement that actually matters for feeding is elevation: the ability to lift the mid and back of the tongue up to the palate to create suction.

A baby can have perfectly good protrusion and still be unable to elevate. Plenty of children have been reassured on the basis of a tongue they could poke out, while the movement that was actually causing the problem was never checked.

So when might treatment be appropriate?

Treatment is considered when a restriction is genuinely limiting function and releasing it is likely to help. That means looking at what the tongue can and cannot do, and at what is actually happening for your child and, in the case of a baby, for you.

The tongue needs to be able to extend, elevate, cup, move side to side, spread, and control a swallow. Restriction of any one of those can affect feeding.

If your child’s tongue is doing its job, a visible frenulum is not a reason to intervene.

Watching and waiting is a real option

Active monitoring — keeping an eye on things, with support, without rushing to a procedure — is a legitimate choice, and it is one we discuss openly with families. Some babies adapt. Not every tie causes a functional problem.

What we would gently steer you away from is passive waiting, where a real difficulty is left unsupported in the hope that it resolves itself. If feeding is painful, if a child is not managing food, or if therapy is not progressing, that deserves a look — even if the answer turns out to be that no procedure is needed.

And sometimes a release is not the answer even when function is restricted

A tongue tie is not the only reason a tongue may not work well. Mouth breathing, nasal obstruction or allergies, low muscle tone, the shape of the palate and other differences can all produce a similar picture.

That is a large part of what a functional assessment is for: working out what is actually driving the difficulty. Sometimes it is a tie. Often it is a combination of things. Sometimes it is something else entirely, and the right next step is a different professional altogether — an ENT specialist, a lactation consultant, a speech pathologist or an orofacial myofunctional therapist.

What about lip ties?

We are deliberately cautious here. There is currently no evidence that releasing a lip tie in infancy prevents a gap between the front teeth, and lip ties are not released routinely at Tooth Town.

Lip ties are assessed in consultation with the allied health professionals already involved in your child’s care, rather than in isolation. For a baby, that is usually a lactation consultant. For an older child, a myofunctional therapist or speech pathologist may well be the person who raises the concern in the first place. Their observations of how the lip is actually working matter more than how it looks, and we would not assess or treat a lip tie on appearance alone.

If you have seen marketing suggesting otherwise, it is reasonable to treat it with some scepticism.

What we will and will not promise

We will give you a careful, honest assessment and a clear explanation of what is realistic for your child.

We will not tell you a release is needed when it is not. We will not promise that a procedure will resolve feeding, speech, sleep or any other concern, because these things usually have several contributing factors and a tie is only ever one of them. And a consultation does not mean treatment has already been decided — for many families, the assessment is reassurance that nothing needs doing.

Common questions

Does a tongue tie always need to be treated?

No. Many ties never cause a problem and need no treatment. Treatment is only considered when a restriction is genuinely affecting function and a release is likely to help.

My baby can poke her tongue out — does that rule out a tie?

No. Protrusion is one of the least functionally important movements. Elevation — lifting the tongue to the palate — is what breastfeeding depends on, and the two are independent of each other.

Does a higher grade mean it is more serious?

Not necessarily. Grade describes anatomy, not effect. A small anterior tie can cause significant feeding difficulty, and a higher-grade posterior tie may have little impact in a different child.

Will a release fix my child’s speech or sleep?

We would not promise that. Speech, feeding and sleep are complex and usually have several contributors. Your dentist will give you an honest picture for your child rather than a guarantee.

If we come for an assessment, will you recommend a procedure?

Not necessarily, and often not. The consultation is an assessment first. Many families leave reassured that no treatment is needed.

Function is looked at in every consultation, not just this one

You do not need to book a tongue tie assessment for someone to notice a problem.

Every consultation at Tooth Town looks at how your child’s mouth is working, not only at their teeth.
