TL;DR

Tongue tie (ankyloglossia) can make specific speech sounds harder to produce, particularly /r/, /l/, /s/, /z/, /th/, and /d/. But most children with tongue tie develop speech in the typical range, and broad speech delay usually has other causes. A speech-language pathologist, not a surgeon, should assess speech concerns first. Lip tie evidence for speech is even weaker.

What is tongue tie and how common is it?

Tongue tie, the medical term is ankyloglossia, happens when the lingual frenulum (the small band of tissue connecting the underside of the tongue to the floor of the mouth) is shorter, thicker, or tighter than typical. This limits how far the tongue can lift, extend, or move side to side.

Prevalence estimates vary widely. A 2020 systematic review in the journal Pediatrics put the range at 0.1% to 10.7% of infants, with a pooled estimate around 3.9% [1]. That wide range tells you something: clinicians still disagree on what counts as a clinically significant tie versus a normal anatomical variation. Some providers label almost any visible frenulum as a tie. Others reserve the diagnosis for cases that actually restrict function.

Tongue tie is roughly twice as common in boys as in girls, though nobody has a fully convincing explanation for that yet [1].

There is no single standard diagnostic tool. The Hazelbaker Assessment Tool for Lingual Frenulum Function (HATLFF) and the Kotlow classification are both used, but neither has universal adoption. That inconsistency is part of why research results on treatment outcomes are so hard to compare.

Can tongue tie cause speech delay in toddlers?

This is the question most parents come in with, and the honest answer is: it depends what you mean by "speech delay."

Tongue tie can restrict the tongue's range of motion, which can make certain sounds physically harder to produce. That's an articulation problem, not a language delay. A child who has a small vocabulary, isn't combining words on schedule, or doesn't seem to understand language is showing signs of language delay, and tongue tie almost certainly isn't the cause of those things.

The American Speech-Language-Hearing Association (ASHA) notes that ankyloglossia "may" affect speech articulation, particularly sounds that require the tongue tip to elevate or extend, but says many children with tongue tie develop speech normally without any intervention [2]. The word "may" is doing real work in that sentence. It means the relationship is not automatic.

A 2017 systematic review in the International Journal of Pediatric Otorhinolaryngology looked at the evidence linking ankyloglossia to speech and found that the methodological quality of existing studies was low, making it "difficult to draw firm conclusions" about whether frenotomy improves speech outcomes [3]. That's the honest state of the science right now.

Where tongue tie is most likely to matter for speech is in a narrow set of sounds: /r/, /l/, /s/, /z/, /th/, /t/, /d/, and /n/. These all need the tongue tip to lift toward the alveolar ridge or the palate. A child with a tight frenulum may compensate with jaw movement or other tongue positions, which can produce distorted versions of those sounds.

Broad speech delay (few words, late first words, not combining words) is much more commonly linked to hearing loss, language exposure, developmental language disorder, autism, or childhood apraxia of speech. If your child is behind on words and word combinations, tongue tie is unlikely to be the whole story.

Which specific speech sounds does tongue tie affect most?

Not all sounds carry the same risk. The ones that need the tongue tip to elevate, extend past the lower teeth, or make precise contact with the roof of the mouth are the most vulnerable.

SoundWhy it's affectedTypical age of mastery
/t/, /d/, /n/Need tongue tip at alveolar ridgeBy age 3
/l/Tongue tip lifts to alveolar ridgeBy age 5-6
/s/, /z/Groove in tongue tip requiredBy age 7-8
/r/Complex tongue body/tip positioningBy age 6-8
/th/Tongue extends past or touches teethBy age 7-8

Sounds like /p/, /b/, /m/, /f/, /v/, /k/, /g/, and most vowels are produced with little or no tongue tip involvement, so tongue tie rarely affects them.

A few caveats matter here. Most of these sounds aren't expected to be mastered until age 5 to 8, so a 2-year-old mispronouncing /r/ is developmentally normal no matter what the frenulum looks like. Children are also remarkably good at compensating. Many kids with a restricted frenulum find an alternative tongue placement that produces an acceptable-sounding result. And articulation errors for these sounds have plenty of causes beyond tongue tie, including motor planning differences, hearing issues, and simple developmental immaturity.

If you're worried about your child's specific sound errors, a speech therapy speech therapist evaluation is the right first move, not a surgical consultation.

Can a lip tie cause speech delay?

Lip tie gets less research attention than tongue tie, and what exists is mostly about breastfeeding, not speech.

A lip tie happens when the labial frenulum (the band of tissue between the upper lip and the gum) is short or thick enough to restrict how far the lip can curl back or move freely. For breastfeeding newborns this can cause a poor latch. For speech, the honest answer is that there's very little controlled evidence that lip tie causes speech delay or significant articulation problems.

Speech sounds that lean on upper lip movement include /p/, /b/, /m/, /f/, and /v/. In theory a severely restricted upper lip could affect these. In practice, the lip has enough inherent mobility and the frenulum attaches close to the midline, so severe functional restriction is uncommon. Most pediatric dentists and SLPs will tell you that lip tie is far more likely to affect dental spacing and breastfeeding than speech.

The American Academy of Pediatric Dentistry does not currently list speech delay as a primary indication for lip tie release [4]. That's meaningful. If the evidence were strong, it would be in the guidelines.

If you've read online that lip tie is causing your toddler's speech delay, treat that claim with skepticism. Get a speech-language pathology evaluation to identify the actual pattern of delay before pursuing any procedure.

Does releasing a tongue tie (frenotomy) improve speech?

This is where parents most want a clear answer, and where the science is genuinely murky.

Frenotomy (cutting the frenulum) and frenuloplasty (a more involved surgical revision) are both performed. For newborns, the evidence that frenotomy improves breastfeeding is reasonably good, which is why it's more commonly recommended in that context [5].

For speech, the picture is different. The 2017 systematic review mentioned earlier found no high-quality randomized controlled trials on frenotomy for speech outcomes [3]. Later reviews reach the same place: the evidence is too thin to say frenotomy improves speech, and the studies that exist are small, unblinded, and inconsistent [5].

The American Academy of Pediatrics (AAP) published a clinical report in 2020 that stated: "There is insufficient evidence to suggest that frenotomy improves speech outcomes in children with ankyloglossia" [5]. That's the most authoritative statement available right now.

This doesn't mean frenotomy never helps with speech. It means nobody has run the studies needed to prove it does. Some SLPs report that children who couldn't produce certain sounds before a release could produce them after, especially when the release is paired with post-procedure myofunctional therapy. But anecdote isn't evidence, and there's real risk of confirmation bias here.

What most pediatric SLPs and ENTs currently recommend: try speech therapy first. If a child has a genuinely restricted frenulum and isn't making progress on specific sounds despite targeted therapy, then a surgical consult makes sense. Surgery as a first response to speech concerns, before any therapy trial, is hard to justify given the current evidence.

How do you tell if tongue tie is actually affecting speech?

A speech-language pathologist checks several things during an oral mechanism exam.

Range of motion. Can the child lift their tongue tip to the alveolar ridge with the mouth open? Can they extend the tongue past the lower lip? Can they move it side to side to each corner of the mouth? Restricted range here, paired with specific sound errors, points more toward a functional tie than anatomy alone.

The heart-shaped tongue. When a child with a tight frenulum tries to lift or extend the tongue, the tip often inverts or notches in the middle, making a heart shape. This is a commonly cited sign, though not every child with a tie will show it clearly.

Compensatory patterns. Is the child substituting sounds in a way that leans on lots of jaw movement instead of tongue tip movement? That can suggest they're working around a restriction.

Sound-specific errors. If a child only has errors on the sounds that require tongue tip elevation (/t/, /d/, /n/, /l/, /s/, /z/) and produces other sounds clearly, that's a more suspicious pattern than random articulation errors across the board.

Anatomy alone isn't enough. A frenulum that looks short on inspection may not restrict function if the tongue is otherwise strong and mobile. A frenulum that looks unremarkable can still cause problems if it attaches in an unusual spot. Function matters more than appearance.

If you've already been through early intervention and your child is still showing specific articulation errors at an age when those sounds should be mastered, bringing a joint SLP and ENT perspective to the table is reasonable.

What else causes speech delay that gets blamed on tongue tie?

Parents and even some clinicians sometimes over-attribute speech concerns to tongue tie because it's visible, tangible, and has a surgical fix. That can delay finding the real cause.

Hearing loss is the most commonly missed contributor to speech and language delay. A child who can't hear clearly can't learn to produce sounds accurately or build vocabulary at the expected rate. The AAP recommends newborn hearing screening, but mild or progressive hearing loss can appear later. Any child with speech concerns should have an up-to-date hearing evaluation [6].

Developmental language disorder (formerly specific language impairment) affects roughly 7% to 10% of children and has nothing to do with oral anatomy [7]. These children have normal hearing and no structural differences, but language processing is hard for them.

Childhood apraxia of speech is a motor planning disorder where the brain has difficulty coordinating the movements needed for speech. It's often mistaken for tongue tie because the child struggles with specific sounds and speech attempts look effortful. You can read more about that at childhood apraxia of speech.

Autism spectrum conditions frequently include speech and language differences. These range from late talking to complex communication differences that go well beyond what any structural issue could explain. Autism spectrum speech therapy approaches address these differently than articulation-focused therapy.

Thin language input, bilingual mixing confusion, and chronic ear infections (otitis media) also contribute to delayed or atypical speech far more often than tongue tie does.

What should parents do if they suspect tongue tie is affecting their child's speech?

Step one is an evaluation by a licensed speech-language pathologist (CCC-SLP), not a surgeon. An SLP will assess whether your child's sound errors match the pattern you'd expect from a restricted frenulum or whether something else is going on. They can also perform an oral mechanism exam to look at tongue mobility directly.

If the SLP confirms that specific sounds requiring tongue elevation are affected, and that the frenulum appears to restrict movement, the next step is usually a trial of speech therapy, often with exercises targeting tongue tip elevation and strength. If the child makes progress, surgery may not be needed. If progress plateaus despite steady effort, an ENT or pediatric surgeon referral is reasonable.

For children under 3, early intervention services through the IDEA Part C program are available in every state at no cost to families [8]. A referral to early intervention does not require you to already know the cause of the delay.

For toddlers showing broader delays (few words, not combining words, not responding to their name), push for a full developmental evaluation rather than focusing narrowly on tongue anatomy. ASHA has a free online tool called "When to Refer" that gives age-based milestones for parents and professionals [2].

If you want extra support between therapy sessions, some families use structured home practice apps. Little Words, for instance, is an AI-based speech companion built for neurodivergent kids and late talkers. It offers guided activities you can do daily at home alongside professional therapy, not instead of it. Take the start quiz to see if it fits your child's profile.

One thing to avoid: scheduling a frenectomy based on a quick physical check at a dentist's office, without SLP involvement, without a trial of therapy, and without your child having any documented speech concerns. That's getting more common, and the evidence does not support it.

At what age should tongue tie be addressed for speech reasons?

For breastfeeding, the answer is: as early as possible if it's causing problems, because the feeding window is narrow.

For speech, the timeline is different. Most of the sounds most affected by tongue tie aren't expected to be mastered until ages 5 to 8. Treating a 2-year-old with a frenectomy specifically to head off future speech problems isn't supported by evidence. You don't yet know whether the child will have speech problems, and even if they do, therapy is usually the right first response.

If a child is 4 or 5 years old, has been in speech therapy for 6 months or more, is clearly motivated, has a confirmed restriction in oral range of motion, and still can't produce sounds that require tongue tip elevation, then a frenotomy consultation becomes more defensible.

Post-procedure myofunctional therapy is typically recommended when frenotomy is done for speech-related reasons in older children. Without it, the muscle patterns and compensatory habits the child developed don't change on their own just because the frenulum is cut. This is a practical point that sometimes gets glossed over by providers who frame surgery as a standalone fix.

Some older children and even adults address tongue tie for speech reasons. If you're curious about how frenotomy and speech therapy interact in adults, the same basic logic applies: speech therapy for adults can address residual articulation patterns after a release.

How is tongue tie diagnosed and what do the different grades mean?

The Kotlow classification grades lingual frenulum restriction into four classes based on how much free tongue (the part that moves freely) exists [9]:

Kotlow ClassFree tongue lengthClinical significance
Class I (mild)12-16 mmUsually no functional impact
Class II (moderate)8-11 mmMay affect breastfeeding, less often speech
Class III (severe)3-7 mmMore likely to restrict function
Class IV (complete)<3 mmSignificant restriction, most likely to need intervention

The Hazelbaker tool assesses both appearance and function, scoring items like tongue lateralization, elevation, extension, and cupping. A combined appearance and function score below a threshold suggests intervention may be needed [11].

Neither tool has been validated specifically against speech outcomes. Both were developed mostly in the context of breastfeeding. That's another reason why applying them mechanically to predict speech problems is unreliable.

Posterior tongue tie (where the frenulum is submucosal and not visible without manual palpation) is a particularly contested diagnosis. Some providers diagnose it frequently. Others question whether it exists as a meaningful clinical entity. The research base here is thin. If you're told your child has a posterior tie that requires release for speech, getting a second opinion from an SLP who specializes in feeding and swallowing is not an overreaction.

What does speech therapy for tongue tie actually look like?

If an SLP decides that tongue tie is restricting specific sounds, therapy usually centers on a few things.

Oral motor exercises to improve tongue tip strength and range of motion. These might include tongue tip taps on the alveolar ridge, lateral tongue movements, and exercises that train the tongue to move independently of the jaw.

Sound-specific practice once enough tongue mobility is there. The SLP targets the affected sounds in isolation, then syllables, then words, then conversational speech in a hierarchy that adjusts based on how the child responds.

Compensatory strategy adjustment. If the child has developed unusual tongue placements to work around the restriction, the SLP helps them unlearn those habits and replace them with more typical placements.

Parent training. For young children especially, what happens between sessions matters as much as what happens in the clinic. SLPs will usually give home practice activities, often 5 to 15 minutes a day, to reinforce what's being worked on.

Myofunctional therapy is a specialized branch of this that focuses on how oral muscle function, resting posture, swallowing, and speech relate to each other. If you're going through a frenotomy, post-op myofunctional therapy is almost always recommended by the operating provider.

Frequently asked questions

Can tongue tie cause speech delay in a 2-year-old?

Tongue tie is unlikely to cause the broad speech delay (few words, not combining words) that most parents worry about in a 2-year-old. It can affect specific sounds that require tongue tip elevation, but most of those sounds aren't expected to be mastered until age 5 to 8. If a 2-year-old is significantly behind on words, hearing loss or a language disorder is a more likely explanation. Get an SLP evaluation first.

Can a lip tie cause speech delay in toddlers?

There's very little research supporting a link between lip tie and speech delay. Lip tie is more commonly tied to breastfeeding difficulties and dental spacing. The sounds most affected by lip mobility (/p/, /b/, /m/, /f/, /v/) are usually mastered early and need minimal lip restriction to go wrong. The American Academy of Pediatric Dentistry does not list speech delay as a primary indication for lip tie release. A speech-language pathology evaluation should come before any procedure.

Will cutting a tongue tie fix speech problems?

Not automatically. The AAP stated in 2020 that there's insufficient evidence to say frenotomy improves speech outcomes. Some children show improvement after release combined with myofunctional therapy, but the research is weak and mostly based on small, uncontrolled studies. For children with speech concerns, a trial of speech therapy before surgery is the standard of care. Surgery without post-op therapy rarely produces lasting change in speech patterns.

What sounds are affected by tongue tie?

The sounds most likely to be affected are /r/, /l/, /s/, /z/, /th/, /t/, /d/, and /n/. These all need the tongue tip to lift, extend, or make precise contact with the roof of the mouth or teeth. Sounds like /p/, /b/, /m/, /k/, /g/, and most vowels need little tongue tip movement and are rarely affected. Keep in mind these sounds have late mastery ages (up to 7 to 8), so errors in a young child may be developmental, not structural.

How do I know if my child's speech delay is from tongue tie or something else?

A licensed speech-language pathologist can assess both your child's speech pattern and oral anatomy. Tongue tie tends to affect a specific cluster of sounds requiring tongue tip elevation, while leaving other sounds intact. Broad language delay (vocabulary, grammar, comprehension) is almost never caused by tongue tie. Hearing loss, developmental language disorder, childhood apraxia of speech, and autism are far more common causes of significant speech delay and should be ruled out.

At what age is it too late to treat tongue tie for speech?

There's no firm upper age limit. Frenotomy and myofunctional therapy are performed in older children, teens, and adults who have speech or other functional concerns related to tongue restriction. Older children and adults may need more intensive post-procedure therapy because compensatory habits are more ingrained. Some adults do address tongue tie for speech reasons. Whether it's worthwhile depends on the functional restriction present and the specific speech concerns, best assessed by an SLP.

Is posterior tongue tie real and can it cause speech problems?

Posterior tongue tie is a contested diagnosis. It refers to a submucosal frenulum that isn't visible without manual palpation. Some providers diagnose it frequently; others argue it's over-diagnosed. Research specifically linking posterior tie to speech outcomes is nearly nonexistent. If you're told your child has a posterior tie that requires release for speech purposes, getting a second opinion from an SLP who specializes in feeding and oral function is a reasonable step before agreeing to any procedure.

Should I see a dentist, ENT, or speech therapist first for suspected tongue tie?

Start with a speech-language pathologist (CCC-SLP). They can assess whether your child's specific speech errors match the pattern expected from tongue restriction, perform an oral mechanism exam, and tell you whether a surgical referral is warranted. Going straight to a dentist or surgeon for speech concerns risks getting a structural answer to what may be a motor, language, or neurological question. The SLP can refer to an ENT or pediatric surgeon if needed.

Does tongue tie always need to be treated?

No. Many people have a short or tight frenulum and no functional problems at all. Treatment is only indicated when tongue tie is causing documented functional difficulty, whether that's breastfeeding, speech, dental issues, or swallowing. A visible frenulum alone is not a reason to intervene. The AAP recommends that treatment decisions be based on functional assessment, not anatomy alone. Watchful waiting combined with speech therapy is appropriate for many children.

Can tongue tie cause lisping?

Yes, a restricted frenulum can contribute to a lisp, particularly an interdental lisp (where /s/ and /z/ are produced with the tongue between or against the teeth) or a lateral lisp. Both involve the tongue tip failing to make the precise groove needed for clear sibilant sounds. That said, most lisps in young children are developmental and resolve without intervention. A lateral lisp (air comes out the sides) is less likely to resolve on its own and often benefits from speech therapy regardless of tongue anatomy.

What is myofunctional therapy and does my child need it?

Myofunctional therapy is a specialized type of therapy that targets the muscles of the mouth, tongue, and face, addressing resting posture, swallowing patterns, and speech. It's most commonly recommended after a frenotomy to help retrain muscle habits that formed around a restricted frenulum. Not every child with tongue tie needs it. It's most relevant when a surgical release has been done in an older child or when there are documented issues with tongue posture or swallowing alongside speech concerns.

Is tongue tie hereditary?

There appears to be a genetic component. Studies report familial clustering of ankyloglossia, and it's about twice as common in boys as girls. Some research points to variants in genes involved in midline development, though the genetic picture is not fully worked out. If a parent or sibling has a tongue tie, a child is more likely to have one too, but that alone doesn't mean it will cause functional problems.

Can tongue tie affect eating as well as speech?

Yes. Beyond breastfeeding in newborns, older children with tongue tie sometimes have difficulty manipulating food in the mouth, particularly chewing tougher textures or moving food from side to side. Some kids avoid certain textures for this reason. Feeding difficulties related to tongue tie are often addressed by an SLP with feeding specialization or an occupational therapist. If your child has both speech concerns and significant mealtime difficulties, a combined feeding and speech evaluation makes sense.
