Posterior Tongue Tie: Understanding and Treating the Condition

Have you ever noticed a baby struggling to latch while feeding? Or perhaps an older child is having trouble saying certain words clearly? These could be signs of something called a “tongue tie.” And not just any tongue tie, but a posterior tongue tie.

It sounds a bit like a secret agent's gadget, doesn't it? But don't worry, it's a real and common condition that can affect people of all ages, from tiny newborns to adults. In this blog, we're going to break down what a posterior tongue tie is, how it can affect you or your loved ones, and most importantly, how it can be treated.

We'll keep things super simple, so you don't need a medical degree to understand it!

What is Posterior Tongue Tie?

Imagine your tongue as a super-flexible muscle, like a gymnastics champion. It's meant to move freely in all directions, helping you do everything from eating and speaking to even breathing properly. Now, underneath your tongue, there's a small piece of tissue that connects it to the floor of your mouth. This is called the frenulum.

Think of the frenulum as an anchor. Normally, it's thin and stretchy, allowing your tongue to move without a fuss. But sometimes, this anchor can be too short, too thick, or too tight. When this happens, it's called a “tongue tie,” or in medical terms, “ankyloglossia.”

Now, here's where the “posterior” part comes in. You might have heard of a “classic” tongue tie where you can clearly see the tight frenulum at the very tip of the tongue. A posterior tongue tie is a bit trickier to spot. It's when the tight frenulum is further back, under the main body of the tongue, often hidden by a thin layer of mucous membrane. It's like a secret, hidden restriction that can still cause just as many problems as the more obvious type.

So, in simple terms, a posterior tongue tie is when the attachment under the tongue is too tight and restricts the tongue's movement, but it's not immediately visible at the front of the tongue.

It's a bit like having a short leash on a very energetic puppy – the puppy wants to run, but the leash holds it back.

Symptoms and Signs of Posterior Tongue Tie

Because a posterior tongue tie is often hidden, its symptoms can sometimes be mistaken for other issues. However, if you know what to look for, you might start connecting the dots. The signs can vary depending on a person's age.

In Babies

Difficulty breastfeeding: This is often the most common and earliest sign. Babies might struggle to latch deeply, slip off the breast, make clicking noises, or not gain enough weight. Mums might experience a lot of pain during feeding, cracked nipples, or low milk supply.
Colic-like symptoms: Excessive gas, fussiness, and reflux can sometimes be linked to a tongue tie because the baby swallows more air due to an inefficient latch.
Poor weight gain: If the baby can't extract enough milk, they won't gain weight as they should.
Short, infrequent feeds, or very long, frequent feeds: The baby might feed often but not get much milk, or feed for ages and still not seem satisfied.
Arching and squirming during feeds.

In Children

Speech difficulties: Certain sounds are harder to make, especially “r,” “l,” “t,” “d,” “s,” and “z.” The child might lisp or have unclear speech.
Eating problems: Difficulty chewing certain foods, especially those that require a lot of tongue movement, or gagging easily.
Dental issues: Over time, a restricted tongue can affect how the jaw and palate develop, leading to crowded teeth or a narrow upper jaw.
Mouth breathing: The tongue plays a role in resting on the roof of the mouth. If it can't, the child might habitually breathe through their mouth, which can lead to other health problems.
Picky eating: Due to difficulties with chewing and swallowing.

In Adults

Ongoing speech problems: Speech can still be affected, making communication difficult or frustrating.
Neck and jaw pain: The body compensates for restricted tongue movement, leading to tension in other areas.
Headaches and migraines: Often related to jaw and neck tension.
Sleep apnoea or snoring: The tongue's position can impact airway patency during sleep.
Difficulty with oral hygiene: It can be hard to effectively clean all parts of the mouth if tongue movement is restricted, potentially leading to increased risk of cavities and gum disease.
Difficulty with certain activities: Like playing wind instruments, kissing, or licking an ice cream.

It's important to remember that not everyone with these symptoms has a posterior tongue tie, but if you notice several of them, it's definitely worth getting checked out.

How Posterior Tongue Tie Affects Speech and Oral Health

The tongue is an incredibly important muscle for both speech and the healthy development of your mouth and teeth. When a posterior tongue tie restricts its movement, it can have a ripple effect.

Speech

Imagine trying to tie your shoelaces with one hand tied behind your back. It's tough, right? That's a bit like what happens with speech. To make clear sounds, your tongue needs to be able to reach various parts of your mouth – the roof, behind your teeth, and even curl up. If the tongue is held down, it struggles to form these precise shapes, leading to:

Lisping: Especially with “s” and “z” sounds.
Difficulty with “r” and “l” sounds: These require the tongue to lift and curl.
Unclear articulation: Words can sound mumbled or difficult to understand.
Compensatory movements: The person might try to use their lips or jaw more to compensate, leading to strained speech.

Oral Health

This is where things get really interesting. Your tongue isn't just for talking and eating; it's a vital part of your oral health team!

Palate Development

When the tongue rests properly in the roof of the mouth (the palate), it acts like a natural expander, encouraging the palate to develop a wide, healthy shape. If the tongue can't reach the palate, it can lead to a high, narrow palate, which in turn can lead to:

Crowded teeth: Not enough space for all the teeth to come through properly.
Crossbites: Where the upper teeth don't fit correctly over the lower teeth.
Dental Hygiene

The tongue naturally sweeps food particles away from your teeth after eating. If it can't move freely, food can get stuck more easily, increasing the risk of:

Cavities (dental caries): Food and sugar left on teeth can cause decay.
Gum disease (gingivitis/periodontitis): Plaque build-up can lead to inflamed and bleeding gums.
Airway Development

A narrow palate and a tongue that rests low can contribute to airway issues, potentially leading to snoring and even sleep apnoea, where breathing repeatedly stops and starts during sleep.

So, you can see, a tiny piece of tissue can have a big impact on a person's life, affecting not just how they speak and eat, but also the very structure and health of their mouth.

Causes of Posterior Tongue Tie

The exact cause of a posterior tongue tie isn't always clear, but it's generally understood to be something that happens during development in the womb. It's a congenital condition, meaning it's present from birth.

Think of it like this: as a baby develops, different parts of the body form. The frenulum is one of these parts. In some cases, for reasons that aren't fully understood, this piece of tissue doesn't fully “recede” or thin out as it should. It remains thicker, shorter, or tighter than typical.

Genetics: There's a strong genetic component. If someone in your family has a tongue tie, there's a higher chance that other family members might have one too. It often runs in families, sometimes skipping a generation.
No specific cause: In many cases, there's no clear reason why it happens. It's just one of those variations that can occur during development.

It's important to remember that a posterior tongue tie is NOT caused by anything a pregnant mother did or didn't do. It's simply a natural variation that occurs during foetal development.

Diagnosis: How is Posterior Tongue Tie Identified?

Because posterior tongue ties are often “hidden,” they can be missed by healthcare professionals who aren't specifically trained to look for them. A quick glance at the baby's mouth might not reveal it.

For Babies and Children

Observation of symptoms: A healthcare professional, often a lactation consultant, paediatrician, or dentist with expertise in tongue ties, will start by listening to your concerns and observing the symptoms. For babies, this includes watching them feed.
Physical examination: This is crucial. The professional will use a gloved finger to lift the tongue and feel for the frenulum gently. They are looking for:
- Tightness and thickness: Is the frenulum unusually tight or thick?
- Restriction of movement: How far can the tongue lift? Can it reach the roof of the mouth easily? Can it move side-to-side freely?
- “Heart-shaped” tongue: Sometimes, if the frenulum is very tight, the tip of the tongue can look “heart-shaped” when the child tries to lift it.
Functional assessment: The most important part of the diagnosis is how the tongue functions. Even if the frenulum doesn't look obviously tight, if it's restricting the tongue's ability to perform its necessary actions (like lifting, extending, or sweeping), then it's considered a problem.

For Adults

Discussion of symptoms: Adults will typically present with speech issues, jaw pain, or other symptoms.
Oral examination: A dentist or an oral health therapist familiar with tongue ties will examine the tongue's range of motion, observe how it moves during speech, and feel the frenulum's attachment. They might also look at the palate's shape and dental alignment.
Speech assessment: If speech is a primary concern, a speech pathologist might be involved to assess specific sound production.

It's really important to seek out a healthcare provider who has specific training and experience in diagnosing and treating tongue ties. Not all professionals are equally knowledgeable in this area.

Treatment Options for Posterior Tongue Tie

The good news is that posterior tongue tie is treatable! The primary treatment is a simple procedure to release the tight frenulum.

Frenotomy (or Frenectomy for Tongue Tie)

This is the most common and effective treatment. It's a quick and relatively minor procedure where the tight frenulum is released.

How It's Done
- Scissors: For babies, a small, sterile pair of scissors can be used to snip the frenulum. This is often done without anaesthesia, or with just a topical numbing gel, as there are very few nerve endings in that area. It's incredibly fast, often taking just a few seconds.
- Laser: For babies, children, and adults, a laser can be used. This method is often preferred because it's very precise, causes minimal bleeding (the laser also cauterises the tissue), and can lead to faster healing. It might require a local anaesthetic for older children and adults.
Who Performs It?

For babies, it can be performed by specifically trained paediatricians, lactation consultants, or, increasingly, general dentists or oral surgeons with special training. For older children and adults, a dentist Launceston or an oral surgeon often performs the procedure.

Post-Procedure Care

After the frenotomy, specific exercises are often recommended. These are sometimes called “wound management exercises” or “stretching exercises.” They are crucial to prevent the frenulum from reattaching as it heals. Think of it like physiotherapy for the tongue! These exercises are usually simple movements that you do several times a day for a few weeks.

Supportive Therapies

Lactation support: For babies, working with a lactation consultant is essential after the procedure to help improve latch and feeding.
Speech pathology: For children and adults with speech difficulties, working with a speech pathologist before and after the procedure can help retrain the tongue to make new movements and correct speech patterns.
Myofunctional therapy: This is a type of therapy that focuses on strengthening the oral muscles and retraining proper tongue resting posture, swallowing, and breathing. It can be incredibly beneficial, especially for older children and adults, to maximise the benefits of the frenectomy.

Benefits of Treatment for Posterior Tongue Tie

The benefits of treating a posterior tongue tie can be life-changing, especially when addressed early.

For Babies

Improved breastfeeding: This is often the most immediate and dramatic benefit. Better latch, less pain for mum, increased milk supply, and better weight gain for baby.
Reduced reflux and colic symptoms: Due to less air swallowing during feeds.
Better sleep: A baby who feeds more efficiently and is less gassy tends to sleep better.
Reduced risk of future issues: Addressing it early can prevent many of the speech and oral health problems seen in older children and adults.

For Children

Clearer speech: Improved articulation and ability to make previously difficult sounds.
Easier eating: Better chewing and swallowing.
Improved oral development: Encouraging proper jaw and palate growth, potentially reducing the need for extensive orthodontic work later.
Better breathing patterns: Promoting nasal breathing and proper tongue posture.

For Adults

Relief from pain: Reduction in neck, jaw, and headache pain.
Improved sleep: Less snoring and improved sleep quality.
Better speech clarity: Enhanced communication and confidence.
Easier oral hygiene: Ability to clean teeth and gums more effectively.
Overall improved quality of life.

The goal of treatment isn't just to cut a piece of tissue; it's to restore full function to the tongue, allowing the individual to thrive in all aspects of their oral health and beyond.
