What Is Tongue-Tie and Why It Happens
Understanding the Lingual Frenulum and Its Role in Tongue Movement
During early fetal development, a baby’s tongue forms from tissues in the floor of the mouth. As the tongue grows and lifts away, a small fold of tissue known as the lingual frenulum remains underneath. This band connects the underside of the tongue to the floor of the mouth and helps stabilise movement as the tongue learns to lift, suck, and swallow.

When Developmental Separation Fails: Why Some Babies Are Born with Tongue-Tie
- Anterior tongue-tie, where the restriction is clearly visible near the tip of the tongue.
- Posterior tongue-tie, where the restriction lies deeper and is harder to see but still limits movement.

How the Tongue Forms During Early Pregnancy
The Stages of Tongue Development in the Womb
By the fourth week of pregnancy, the foundation of the tongue begins to take shape. It develops from multiple swellings in the floor of the embryo’s mouth, which gradually fuse and grow forward. At this stage, the tongue is still connected to the surrounding tissues of the mouth floor, with only limited mobility.
As pregnancy progresses, the tongue lengthens, thickens, and starts to separate from those neighbouring tissues. This separation is essential for proper swallowing and feeding function after birth. By around the eighth week, small muscles and connective fibres begin organising into a structure capable of fine, coordinated movement. These muscles are controlled by cranial nerves that also govern sucking and swallowing reflexes.
The underlying tissue network, including the developing lingual frenulum, supports the tongue’s position and stability. This complex process involves several layers of communication between cells, guiding how the tissue should grow, reshape, and differentiate. Any deviation in timing or cellular signalling during this phase can influence how freely the tongue will later move.
Osteopathically, this early patterning has long-term implications. Restrictions or asymmetries in tongue movement may relate not only to the frenulum but also to how the cranial base, jaw, and hyoid bone have developed in relation to one another. Subtle tension patterns established before birth can sometimes persist into infancy, affecting feeding comfort and coordination.

How Tongue-Tie Affects Feeding, Breathing, and Early Function
Why Restricted Tongue Movement Causes Feeding Challenges
A baby’s ability to feed efficiently depends on precise coordination between the tongue, jaw, lips, and soft palate. The tongue must lift, cup, and move in a wave-like motion to draw milk effectively while maintaining a seal. When tongue movement is restricted by a tight or unreceded frenulum, that sequence becomes disrupted.
Instead of the tongue performing a smooth peristaltic motion, the baby may compensate by using the lips or jaw to create suction. This extra effort can make feeding slow, noisy, and tiring. The latch may break repeatedly, producing clicking sounds as air enters the mouth. Babies with restricted tongues often swallow more air, leading to trapped wind, reflux-type symptoms, and general irritability after feeds.
For mothers who are breastfeeding, restricted tongue mobility can cause nipple pain, bruising, or blocked ducts because the baby cannot maintain a consistent latch. Bottle-fed babies can experience similar problems, including gulping, leaking milk, or needing frequent breaks due to fatigue. These challenges can contribute to poor weight gain, extended feeding sessions, or stress around mealtimes.
From an osteopathic viewpoint, these difficulties are not limited to the mouth. When a baby strains to feed, the entire musculoskeletal system responds. The jaw muscles may tighten, the neck may arch, and cranial tissues can develop subtle tension patterns. These compensations sometimes persist even after a tongue-tie has been released, which is why osteopathic treatment can be beneficial both before and after the procedure.
The Link Between Tongue-Tie and Airway or Digestive Strain
Tongue-tie does not only affect feeding mechanics; it can also influence how a baby breathes and digests. When the tongue cannot move freely, it may sit lower in the mouth, altering how air flows through the nasal passages and throat. Babies with tongue restriction often rely more on mouth breathing, which can lead to disrupted sleep, noisy breathing, or increased effort when feeding and resting.
During feeding, restricted tongue movement can interfere with the swallow–breathe rhythm. Instead of a smooth pattern where the baby sucks, swallows, and breathes comfortably, there may be pauses, spluttering, or coughing. These interruptions can cause the baby to take in air, which may lead to discomfort, trapped wind, and reflux-like symptoms. Over time, these challenges may influence digestion, leaving babies more prone to hiccups, colic, or unsettled periods after feeding.
Osteopathically, the airway, diaphragm, and cranial base work in concert. Tension in one area can affect the others, especially in newborns where structures are still soft and highly responsive. Gentle osteopathic assessment can identify whether mechanical restrictions in the jaw, tongue, or upper neck are contributing to these breathing and digestive imbalances.
At Key Osteopaths, many babies from West Byfleet, Woking, and Weybridge present with signs of airway or digestive strain linked to tongue restriction. Treatment aims to improve structural balance, relieve tension, and support smoother coordination between breathing and swallowing.
Early Clues — Clicking, Gulping, Dribbling, or Poor Weight Gain
Parents often notice the early signs of tongue-tie long before a formal diagnosis is made. The most common clues appear during feeding. A clicking or popping sound while the baby feeds is a strong indicator that the seal is breaking repeatedly, allowing air to enter the mouth. Gulping, coughing, or milk leaking from the corners of the mouth can follow, as the baby struggles to maintain suction.
Dribbling and frequent pauses during feeding may suggest the tongue cannot sustain its forward and upward movement. Some babies become frustrated or fall asleep mid-feed because of the effort required to maintain suction. Others feed for long periods but still seem hungry, or experience excessive wind, discomfort, and difficulty settling after meals. Over time, these issues can affect weight gain and overall energy levels.
Observation is key. A baby who tires easily, makes clicking noises, or gulps air during feeds may be compensating for restricted tongue motion rather than feeding normally. Recognising these subtle patterns early allows for timely intervention and greater comfort for both baby and parent.
At Key Osteopaths, clinicians frequently help families across Guildford, Ripley, Cobham, and East Horsley identify and understand these early indicators. A detailed osteopathic assessment can pinpoint where restriction or tension exists and support the baby’s ability to feed more effectively and comfortably.
If you’ve noticed any of these early signs: clicking during feeds, gulping, dribbling, or slow weight gain—our osteopaths at Key Osteopaths can help identify and address the underlying causes. Serving families across West Byfleet, Woking, Weybridge, Guildford, Ripley, Cobham, and East Horsley, we provide gentle, evidence-based osteopathic care to ease feeding strain, improve coordination, and support your baby’s comfort and development.

What Happens If Tongue-Tie Is Left Untreated
Possible Impacts on Feeding, Speech, and Facial Development
When tongue-tie remains untreated, the effects can extend beyond early feeding challenges. In infancy, restricted tongue movement often leads to inefficient milk transfer, prolonged feeds, and excessive swallowing of air. Over time, these issues can contribute to discomfort, trapped wind, and unsettled sleep. As the baby grows, the tongue’s limited range of motion may begin to affect the natural development of speech and facial structure.
Speech development relies heavily on the tongue’s ability to move freely to form sounds, guide airflow, and shape words. A restricted frenulum can limit these precise motions, leading to articulation difficulties or unclear pronunciation later in childhood. Structurally, tongue-tie can also influence how the palate and dental arches form. When the tongue cannot rest properly against the roof of the mouth, the palate may become higher and narrower, affecting both bite alignment and airway space.
Untreated tongue-tie may also contribute to habits such as mouth breathing, which can alter facial muscle tone and cranial development over time. These effects vary in severity but underscore why early recognition and management are important, even if symptoms initially appear mild.
Our osteopaths at Key Osteopaths in West Byfleet, Woking, and Weybridge often see the long-term effects of unresolved tongue restriction. By identifying tension patterns early, they help parents understand how these mechanical limitations can influence a child’s feeding, facial growth, and speech progression.
The Relationship Between Oral Function, Posture, and Cranial Balance
The tongue plays a central role not only in feeding and speech but also in maintaining balance and stability throughout the head and neck. When it is restricted, the body often compensates through subtle postural adaptations. The baby may tilt or rotate the head to feed more easily, arch the neck to breathe, or develop tension through the jaw and shoulders.
These compensations can affect cranial motion and spinal alignment. In babies, whose skeletal structures are still flexible, even minor asymmetries can influence how the skull bones adapt during growth. Over time, this may result in uneven muscle tone, mild flattening of the head shape, or strain through the upper neck and shoulders.
Our osteopaths often observe these patterns during assessments. By gently evaluating how the tongue, jaw, and cranial base work together, they can identify areas where restriction is causing wider imbalances. Treatment aims to restore fluid motion through these regions, supporting more natural posture, balanced cranial function, and easier feeding.
Parents from Guildford, Ripley, and Cobham often report that after gentle osteopathic care, their babies appear calmer, feed more comfortably, and show improved head and neck movement. This reflects how closely oral function is linked to the body’s overall alignment and comfort.
How Osteopathy Can Help Even Before a Frenulotomy
Osteopathic treatment can be extremely valuable even before a tongue-tie release is considered. When restriction exists, the surrounding muscles and connective tissues often develop compensatory tension to help the baby feed and breathe. These areas can become tight or unbalanced, amplifying the symptoms caused by the tongue-tie itself.
Through gentle techniques, our osteopaths can help release these areas of strain, improve tongue and jaw coordination, and reduce the baby’s discomfort during feeding. This approach can make feeding easier and, in some cases, reduce the perceived severity of the tongue-tie. When a frenulotomy is necessary, osteopathic treatment beforehand helps prepare the baby’s body by restoring balance and minimising residual tightness, supporting a smoother recovery afterward.
At Key Osteopaths, many parents from East Horsley, Dorking, and Pyrford choose to have their baby assessed before a tongue-tie procedure. This proactive approach ensures that any underlying tension patterns are addressed early, improving outcomes whether or not surgical release becomes necessary.

FAQ — Parents’ Most Common Questions About Tongue-Tie
How do I know if my baby has a tongue-tie?
The most common sign of tongue-tie is difficulty feeding. Babies may struggle to latch, make clicking sounds, dribble milk, or seem unsettled during or after feeds. Some babies feed for long periods but still appear hungry, while others tire quickly or fall asleep before finishing.
Parents may also notice that the baby’s tongue looks heart-shaped or that it cannot lift easily when crying. However, not all tongue-ties are visible. Posterior tongue-tie, which lies deeper beneath the tongue, can cause just as much restriction but is harder to see.
Our osteopaths at Key Osteopaths regularly assess babies from West Byfleet, Woking, and Weybridge who show these subtle signs. A thorough evaluation helps identify whether a restriction exists and how it might be affecting feeding, breathing, or comfort.
What can tongue-tie be mistaken for?
Tongue-tie can sometimes be confused with other issues that affect feeding and comfort. Babies with tight jaw muscles, tension in the neck, or cranial strain from birth may show similar symptoms such as poor latch, clicking, or dribbling. Reflux, allergies, or feeding technique can also mimic tongue-tie symptoms.
Because the causes of feeding difficulty are varied, it is important to look at the whole picture rather than just the appearance of the tongue. Our osteopaths are trained to assess the baby’s structure, movement, and coordination, helping parents distinguish between tongue restriction and other underlying factors that may be contributing to the problem.
Can tongue-tie cause reflux, colic, or wind?
Yes, it can contribute to these symptoms. A restricted tongue often prevents a baby from maintaining a proper seal during feeding, allowing air to be swallowed along with milk. This air can become trapped, leading to wind, discomfort, and reflux-like symptoms. Some babies arch their backs, cry after feeds, or struggle to settle because of the resulting pressure in the stomach and diaphragm.
Osteopathically, these symptoms are often linked to tension in the diaphragm, jaw, and upper neck. By improving feeding mechanics and releasing associated tightness, our osteopaths at Key Osteopaths help babies feed more efficiently, reducing trapped air and easing discomfort related to colic and reflux.
At what age should a tongue-tie be cut?
There is no fixed age for a tongue-tie release. The right time depends on the severity of restriction, the baby’s feeding efficiency, and the degree of discomfort experienced. Many babies benefit from early assessment within the first few weeks, as intervention at this stage can improve feeding and prevent ongoing strain.
If the restriction is mild and feeding is progressing well, monitoring with osteopathic support may be enough. For more pronounced ties, a procedure called a frenulotomy can be performed at any age once a clear functional restriction is confirmed. Our osteopaths often provide pre- and post-release support to ensure smooth recovery and help optimise tongue movement following the procedure.
Is tongue-tie painful for babies?
The restriction itself is not usually painful, but the tension it creates can lead to discomfort. Babies may show signs of frustration, fatigue, or distress during feeding because of the extra effort required. The tightness can also cause tension through the jaw, neck, and shoulders, contributing to fussiness or unsettled sleep.
Gentle osteopathic treatment can ease this strain by improving movement and balance in the affected areas. At Key Osteopaths, our clinicians use soft, precise techniques designed for newborns, ensuring that treatment remains safe, comfortable, and calming for the baby.
Who can diagnose and treat tongue-tie?
Tongue-tie can be assessed by trained professionals such as lactation consultants, paediatricians, dentists, and specialist practitioners experienced in infant feeding. An accurate diagnosis involves observing both the structure of the frenulum and how the baby functions during feeding.
At Key Osteopaths, our osteopaths work alongside parents, health visitors, and tongue-tie practitioners to ensure babies receive the most appropriate care. Their detailed assessments focus not just on the visible restriction but on how the baby’s body is adapting to it. This whole-body approach allows for early, effective support, whether through osteopathic treatment, referral for a release, or ongoing feeding guidance.
