Why a Functional Tongue-Tie Assessment Matters for Your Child

If you’ve ever heard the term “tongue tie,” you may have found yourself wondering:

What exactly does that mean? Does my child have one? Could it be contributing to feeding or speech difficulties? And does it need to be treated?

These are common questions—and the answers aren’t always as simple as looking underneath your child’s tongue.

A tongue tie, also called ankyloglossia, occurs when the tissue connecting the tongue to the floor of the mouth restricts the tongue’s movement.

But here’s the important part: Having a visible frenulum does not automatically mean there is a functional problem.

What matters is how your child’s tongue works.

That’s why, when concerns about a possible tongue tie arise, looking at both structure and function can give families a much clearer picture of what may actually be going on.

It’s More Than Just Looking Under the Tongue

You may have seen pictures online comparing a “normal” frenulum with a “tongue tie.” While pictures can be helpful, they don’t tell the whole story.

Two children can have frenulums that look very similar but use their tongues very differently.

One child may move their tongue easily and have no related difficulties. Another may have trouble lifting, moving, or coordinating their tongue during activities like eating or speaking.

A functional assessment looks beyond appearance and considers questions such as:

Can your child lift their tongue toward the roof of their mouth?
Can they move it from side to side?
Can they extend their tongue forward?
Can they move their tongue independently from their jaw?
Can they create and maintain suction?
Where does their tongue naturally rest?
How does the tongue move during eating and swallowing?
Is your child using extra jaw movements, muscle tension, or other compensations?

Rather than asking only, “Does my child have a tongue tie?” we want to understand:

“Can my child’s tongue move effectively for the things they need and want to do?”

How Could a Tongue Tie Affect Feeding?

Your child’s tongue does a lot of work during mealtimes!

It helps move food around the mouth, gather food into a manageable ball (called a bolus), and transport that food toward the back of the mouth for swallowing.

When tongue movement is limited, some children find other ways to get the job done.

Depending on the child, you might notice:

Difficulty moving food around the mouth
Food remaining in the cheeks
Difficulty chewing certain textures
A preference for softer or easier-to-manage foods
Gagging with certain foods
Messy eating
Difficulty coordinating sucking, chewing, or swallowing

These signs can have many different causes, so seeing one or more of them does not automatically mean your child has a tongue tie.

That’s why a comprehensive feeding evaluation looks at the bigger picture—including oral-motor skills, sensory needs, coordination, feeding history, and how your child actually manages food during meals.

What About Speech?

Parents are sometimes told that a tongue tie is the reason their child is having difficulty producing certain speech sounds.

The relationship isn’t always that straightforward.

The tongue is important for speech, and children need to coordinate precise tongue movements to produce many sounds clearly. However, not every child with a tongue tie has a speech sound disorder, and not every speech sound disorder is related to a tongue tie.

During an assessment, a speech-language pathologist can look at whether your child’s tongue movement appears restricted and, importantly, whether that restriction is actually interfering with the movements needed for speech.

This helps us focus on your child’s individual speech patterns rather than assuming the frenulum is the cause based on appearance alone.

What About Breathing, Sleep, and Oral Posture?

Tongue function is also connected to the larger orofacial system, including the lips, jaw, palate, and airway.

When we look at orofacial function, we may consider things such as:

Where the tongue rests when your child is not eating or talking
Whether the lips are typically open or closed at rest
Nasal versus mouth breathing
Swallowing patterns
Jaw and facial muscle patterns
Concerns related to sleep or airway function

This does not mean that a tongue tie automatically causes mouth breathing or sleep difficulties.

Instead, these are pieces of the bigger picture that may be worth exploring when a child is already experiencing related concerns.

Does Every Tongue Tie Need Treatment?

No.

This is one of the most important things for families to understand.

A child may have a frenulum that appears restrictive but functions very well. When there is no meaningful functional difficulty, treatment may not be necessary.

If an evaluation shows that tongue movement is significantly limited and that limitation appears to be contributing to feeding, speech, swallowing, or other functional concerns, your child’s healthcare team can help determine appropriate next steps.

The decision should be based on your child’s individual function and needs—not simply on what the frenulum looks like.

Why a Team Approach Matters

Tongue-tie concerns can involve several areas of development, which is why collaboration can be so helpful.

Depending on your child’s needs, their team may include professionals such as:

A speech-language pathologist
A pediatric dentist or dentist
An ENT
A pediatrician
A lactation professional
An occupational therapist
Other appropriately trained healthcare professionals

Each professional looks at a different piece of the puzzle.

For example, a speech-language pathologist may evaluate speech, feeding, swallowing, and oral-motor function. A dentist or ENT can assess oral anatomy and determine whether a procedure is appropriate. Other providers may help evaluate airway, dental, feeding, or developmental concerns.

At Radiant Moments, we believe strongly in looking at the whole child—not just the frenulum.

When appropriate, collaboration among providers can help families better understand what is contributing to a child’s difficulties and determine the most appropriate plan.

The Bottom Line

If someone tells you that your child may have a tongue tie, you don’t have to make a decision based on a picture alone.

Instead, one of the most useful questions you can ask is: “How is my child’s tongue functioning?”

A comprehensive functional assessment looks at your child’s history and observes how their tongue works during the activities that matter to them—whether that’s eating, swallowing, speaking, resting, or, when relevant, breastfeeding.

A tongue tie isn’t simply about what you can see.

It’s about what your child can do.

Remember

Not every tongue tie requires treatment.

Not every feeding or speech difficulty is caused by a tongue tie.

And two children with similar-looking frenulums may function very differently.

When concerns arise, a comprehensive functional assessment can help identify what is really happening and whether additional evaluation, therapy, or collaboration with another provider may be appropriate for your child.
