Can Tongue Tie Affect Speech Later in Life?

A tongue tie can raise questions for parents, especially when a child begins speaking and certain sounds seem difficult.

You may wonder:

Can tongue tie affect speech?
Could a tongue tie cause speech problems later?
Should my child’s tongue tie be treated before speech develops?
Does tongue tie release improve speech?

These are reasonable questions.

The short answer is that tongue tie can restrict tongue movement in some children, but having a tongue tie does not automatically mean a child will develop speech problems.

The relationship between ankyloglossia, commonly called tongue tie, and speech is still an area where evidence is developing. Research has reported possible improvements in speech-related outcomes after treatment in some children, but the overall evidence remains limited and inconsistent. A systematic review published by the American Academy of Pediatrics found insufficient evidence to determine the effects of treatment on non-breastfeeding outcomes such as speech.

That means parents do not need to assume that every tongue tie needs to be released to protect future speech.

Instead, the focus should be on how the tongue moves, how the child is functioning and whether there is a specific concern that needs assessment.

What is tongue tie?

Tongue tie, or ankyloglossia, occurs when the lingual frenulum — the band of tissue connecting the underside of the tongue to the floor of the mouth — restricts tongue movement.

The appearance of the frenulum can vary considerably from child to child.

Importantly, the appearance of a frenulum alone does not tell you whether it is causing a functional problem.

The American Academy of Pediatrics notes that there are no universally accepted diagnostic criteria for ankyloglossia and that the condition can be overdiagnosed.

This is why assessment should consider function rather than simply how the frenulum looks.

Tongue tie may affect:

• Tongue movement
• Feeding in some infants
• Oral function
• Occasionally, speech-related function

But not every child with a tongue tie will experience difficulties.

Can tongue tie cause speech problems?

This is one of the most common questions parents ask. The answer is not straightforward.

Speech involves much more than simply moving the tongue. Children need to coordinate their lips, tongue, jaw, palate, breathing and voice while also developing language and learning how to produce individual speech sounds.

Some speech sounds require precise tongue movement. If tongue mobility is significantly restricted, it is possible that this could contribute to difficulty producing certain sounds in some children.

However, that does not mean that a child with tongue tie will automatically develop a speech disorder.

There are many other reasons a child may have difficulty with speech sounds, including normal variation in development, hearing difficulties, developmental differences and speech sound disorders.

A child with a tongue tie may therefore have speech difficulties that are related to something other than the tongue tie. This is one reason a broader assessment is important.

What does the research say about tongue tie and speech?

Research into tongue tie and speech has produced mixed findings.

A 2015 systematic review published in Pediatrics examined studies looking at treatment of ankyloglossia for reasons other than breastfeeding, including speech outcomes. Two cohort studies reported improvements in articulation and intelligibility after treatment, while other evidence was less clear. The authors concluded that there was insufficient evidence to determine the effects of treatment on non-breastfeeding outcomes.

More recent paediatric guidance continues to emphasise the uncertainty.

The AAP’s 2024 clinical report states that evidence around ankyloglossia diagnosis and treatment remains limited and that there is significant variation in clinical practice. It also highlights concerns about overdiagnosis.

So it would be inaccurate to tell parents: “Tongue tie will cause speech problems.” It would also be inaccurate to promise: “Releasing tongue tie will prevent speech problems.” The evidence does not support either statement.

What are tongue tie symptoms in children?

Tongue tie symptoms in children can vary depending on the degree of restriction and the child’s age. Some children have no noticeable problems at all. Others may have functional difficulties that are worth discussing with a healthcare professional.

Possible signs can include:

• Difficulty moving the tongue freely
• Difficulty lifting the tongue
• Difficulty extending the tongue
• A noticeable restriction when the tongue is moved
• Difficulty with certain oral movements
• Feeding difficulties in younger children
• Speech concerns in some children

However, these signs are not specific to tongue tie. For example, difficulty with speech sounds does not automatically indicate a restricted frenulum. The child’s overall development and function need to be considered.

Tongue tie and speech are not the same as language development

This distinction is important. Speech refers to how a child produces sounds and words.

Language involves understanding and communicating meaning through words, sentences, gestures and other forms of communication.

A tongue tie affects the physical structure beneath the tongue. It does not, by itself, explain difficulties with understanding language, vocabulary or social communication.

For example, if a child is not yet using many words, a tongue tie should not automatically be assumed to be the cause.

A paediatric assessment may need to consider:

Area	What may be considered
Speech sounds	How clearly the child produces sounds
Language	Understanding and using words
Hearing	Whether hearing may be affecting speech development
Oral movement	How freely the tongue and other structures move
Development	The child’s broader developmental progress
Feeding	Whether there are current oral or feeding difficulties

This broader view helps avoid attributing every communication concern to tongue tie.

Can a tongue tie become a problem later?

A tongue tie does not necessarily become more restrictive as a child grows. The important question is whether the child is experiencing functional difficulty.

A child may have a visible frenulum but have normal tongue movement and no problems. Another child may have restricted movement that becomes more noticeable as they develop new skills.

This is why simply identifying a tongue tie in infancy does not necessarily mean that treatment will be required later.

The American Academy of Pediatrics recommends focusing on symptomatic cases rather than treating an anatomical finding alone.

Should every child with tongue tie have a speech assessment?

Not necessarily. A child with a tongue tie who is communicating well, developing appropriately and has no functional concerns may not need intervention simply because a frenulum is visible.

On the other hand, if there are concerns about speech, oral function, feeding or tongue movement, an assessment may be helpful.

The decision should be based on the individual child, rather than the presence of a tongue tie alone.

What should parents look for before considering treatment?

Before considering tongue tie release, it can be useful to ask:

• What specific problem are we trying to address?
• Is tongue movement actually restricted?
• Is the restriction affecting function?
• Could there be another explanation for the concern?
• Has my child’s hearing been considered where appropriate?
• Would speech or feeding assessment be helpful?
• What does the evidence say about treatment for this particular concern?
• What are the potential benefits and risks?

These questions can help move the conversation away from treating an appearance and towards treating a genuine functional problem.

What happens during an assessment?

A paediatric assessment may begin with a discussion about what parents have noticed.

This might include:

• When the concern started
• How your child’s speech is developing
• Which sounds are difficult
• Whether other people can understand your child
• Feeding history
• Tongue movement
• Other developmental milestones
• Hearing concerns
• Any previous assessments or treatments

The clinician may then examine the mouth and tongue and assess movement and function. Depending on the concern, they may recommend assessment by another professional, such as a speech pathologist or relevant specialist.

The goal is not simply to answer: “Does my child have tongue tie?” It is to understand: “Is the tongue tie affecting my child’s function?”

Does tongue tie release improve speech?

This is where parents should be particularly cautious about online claims. Tongue tie release, also called frenotomy, frenectomy or frenuloplasty depending on the procedure, involves altering or releasing the lingual frenulum.

Some studies have reported improvements in speech-related outcomes following treatment.

However, the quality and design of studies vary, and the evidence is not strong enough to say that tongue tie release will improve speech in every child.

The 2015 AAP systematic review found some evidence of improvement in articulation and intelligibility but concluded that overall evidence was insufficient to establish the benefits of treatment for non-breastfeeding outcomes.

This remains an important consideration when discussing tongue tie release in children. Treatment should be considered when there is a clear functional reason, rather than as a guaranteed way to prevent future speech difficulties.

Tongue tie treatment in Australia

If you’re looking for tongue tie treatment in Australia, it can be difficult to know which approach is right for your child. At Tiny Tusk Paediatrics, we focus first on understanding how a tongue tie may be affecting your child’s speech, feeding, oral function and overall development.

Rather than recommending treatment based on appearance alone, we consider your child’s individual symptoms, tongue movement and functional needs. Where appropriate, we may also recommend working with other healthcare professionals, such as a speech pathologist.

Treatment options can include monitoring, supportive therapies or tongue tie release, depending on the individual child.

The goal is not simply to treat a tongue tie. It’s to understand your child and determine whether treatment is actually needed.

Conclusion

A tongue tie can look concerning, particularly when parents hear that it may affect speech later in life. But a visible tongue tie is not the same thing as a speech disorder.

Some children with tongue tie have no significant difficulties. Others may have genuine functional restrictions that deserve assessment.

If your child is experiencing speech or oral difficulties, the most useful starting point is to understand what is actually causing the problem rather than assuming the frenulum is responsible.

At Tiny Tusk Paediatrics, we look at the whole child — including development, communication, feeding and everyday function — when considering concerns about tongue tie.

If you’re unsure whether your child’s tongue tie needs attention, you don’t have to work it out alone. A paediatric assessment can help you understand what you’re seeing and what, if anything, needs to happen next.

Frequently asked questions

Can tongue tie affect speech?

It may contribute to speech difficulties in some children when tongue movement is significantly restricted, but tongue tie does not automatically cause speech problems. Research into the relationship remains limited and mixed.

Can tongue tie cause speech problems later?

A tongue tie may be relevant to speech in some children, but there is not enough evidence to say that an untreated tongue tie will cause future speech problems. Other developmental, hearing and speech-related factors can also affect communication.

What are tongue tie symptoms in children?

Possible symptoms include restricted tongue movement and, depending on the child, feeding or oral-function concerns. Speech concerns may occur in some children, but they are not proof that tongue tie is the cause.

Does tongue tie affect language development?

Tongue tie primarily concerns the physical movement of the tongue. It does not by itself explain difficulties with language development, such as understanding words or developing vocabulary.

Can tongue tie release improve speech?

Some studies have reported improvements in articulation or intelligibility after treatment, but the overall evidence remains insufficient to guarantee that tongue tie release will improve speech. 

Should every child with tongue tie have it released?

No. Treatment decisions should be based on symptoms, function and individual assessment rather than the appearance of the frenulum alone. Current paediatric guidance also highlights concerns about overdiagnosis and variation in treatment practices.

Does my child need speech therapy or tongue tie release?

It depends on the specific concern. A speech assessment may be appropriate for speech difficulties, while restricted tongue movement may need separate clinical assessment. Sometimes more than one professional may be involved.
