Tongue Tie: Why This Small Piece of Tissue Has a Big Impact on Health

Most people have heard of tongue tie. Far fewer understand what it actually does to the body, and why releasing it can matter well beyond the early weeks of breastfeeding.

As a chiropractor, I see the downstream effects of an unresolved tongue-tie more often than you might expect. Posture, breathing, jaw tension, sleep, and spinal development. These are not separate conversations from a restricted frenulum. They are, in many cases, directly connected to it.

This article is for parents navigating a diagnosis, and for adults who have quietly wondered whether something they've struggled with for years might trace back to a piece of tissue they never knew was restricted.

What Is a Tongue Tie?

Tongue tie, known clinically as ankyloglossia, occurs when the lingual frenulum, the band of tissue connecting the underside of the tongue to the floor of the mouth, is too short, too thick, or too tight. This restricts the tongue's range of motion in ways that affect far more than feeding.

The tongue is not a passive structure. It plays an active role in swallowing, speech, breathing, jaw development, and the structural alignment of the palate. When it can't move freely, the body compensates. And those compensations, over months and years, have consequences.

Tongue tie exists on a spectrum. Anterior ties are visible and relatively straightforward to identify. Posterior ties sit further back under the tongue and are far more commonly missed, yet can be equally significant in their functional impact.

The Feeding Connection: Why It Matters from Day One

For newborns, the conversation about tongue-tie usually begins with breastfeeding. A baby with a restricted tongue cannot create the suction and peristaltic wave motion needed to feed efficiently. The result is often a shallow latch, prolonged feeding sessions, poor weight gain, excessive wind, reflux, and a mother experiencing significant nipple pain and milk supply concerns.

Research published in journals including Breastfeeding Medicine and the Journal of Human Lactation consistently shows that frenotomy, the release of the frenulum, improves latch and reduces maternal nipple pain in the majority of cases where tongue tie is identified as a contributing factor.

But feeding is only the beginning.

Breathing, Airway, and Sleep

The tongue's resting position is directly related to airway development. When the tongue rests correctly, it sits against the roof of the mouth, applying gentle pressure that guides the palate to widen and develop properly. A tongue that is tethered sits low in the mouth instead.

A low tongue posture contributes to a narrow, high-arched palate, which reduces nasal airway space and pushes children toward mouth breathing as a default. Mouth breathing bypasses the nose's role in filtering, humidifying, and warming air. Over time it is associated with altered facial development, disrupted sleep, increased susceptibility to respiratory illness, and in children, behavioural and attention difficulties linked to poor sleep quality.

In adults, an unresolved tongue-tie can be a contributing factor to obstructive sleep apnoea. When the tongue lacks the muscle tone and range of motion to maintain its position during sleep, airway collapse becomes more likely.

The connection between tongue function and breathing is well documented in the dental and orthodontic literature, and the conversation is increasingly crossing into chiropractic, myofunctional therapy, and ENT practice as well.

Jaw, Posture, and the Spine

This is where my clinical interest sits most directly.

The tongue, jaw, hyoid bone, and cervical spine are functionally linked. Tension in one area creates compensation in another. I regularly see patients, both children and adults, presenting with chronic neck tension, forward head posture, and restricted cervical range of motion where tongue tie is part of the picture that hasn't yet been identified.

The hyoid bone, which sits at the base of the tongue and has no direct joint with any other bone in the body, acts as an anchor point for muscles that influence both swallowing and head position. A restricted tongue creates altered tension through the hyoid and into the muscles of the neck and jaw. That tension doesn't resolve on its own, and chiropractic adjustments, while helpful in managing the compensatory patterns, work better and hold longer when the underlying restriction has been addressed.

In children, the impact on development is particularly significant. Restricted tongue function affects how the jaw grows, how teeth erupt, whether orthodontic intervention becomes necessary, and how the child holds their head and shoulders as their body develops.

Adults: Is It Too Late?

No. And this is something I want to say clearly because I see adults dismiss the possibility that their tongue tie is relevant simply because they've managed this long.

Managing is not the same as thriving.

Adults with unresolved tongue tie frequently present with chronic jaw tension, TMJ dysfunction, neck pain, headaches, and in some cases, long-standing difficulties with speech or swallowing they've simply adapted around. Tongue tie release in adults, followed by myofunctional therapy to retrain the tongue's movement patterns, consistently shows meaningful improvement in these presentations.

The research on adult frenotomy outcomes is growing. A 2021 review in the Journal of Oral Rehabilitation noted significant improvements in tongue mobility and associated symptoms following release in adult patients. The rehabilitation component is important: release without retraining leaves the tongue without the muscle memory to use its new range of motion effectively.

The Multidisciplinary Piece

Tongue tie is not a condition that any single practitioner owns. The best outcomes I have seen come from a team approach: an IBCLC (lactation consultant) for feeding assessment in infants, a dentist or oral surgeon experienced in functional frenotomy for the release itself, a myofunctional therapist for pre and post-release rehabilitation, and where relevant, a chiropractor to address the compensatory patterns in the spine, jaw, and cranium that have developed over time.

If you suspect tongue tie in your child or yourself, the starting point is a functional assessment, not just a visual one. Many significant posterior ties are missed on a quick look. A practitioner who assesses tongue lift, tongue lateralisation, and the functional impact of the restriction will give you a far more complete picture than one who simply observes whether the frenulum is visible.

Why I Think This Matters

We are seeing a generation of children with increasingly narrow palates, high rates of mouth breathing, crowded teeth, and disrupted sleep. These are not inevitable. They are, in many cases, the downstream consequences of restricted oral function that went unidentified and unaddressed early in life.

Tongue tie release is not a silver bullet. But as one piece of a thoughtful, multidisciplinary approach to oral and airway health, it is a piece that genuinely moves the needle.

If you have questions about whether tongue tie might be relevant for your child or for yourself, I'm always happy to talk through what I'm seeing clinically and point you toward the right practitioners in our network.
