Tongue-tie: understanding assessment, feeding, treatment and aftercare

A baby can have a visible tongue-tie and feed comfortably, gain weight appropriately and have a settled feeding relationship. Another baby may have feeding difficulties where a restrictive lingual frenulum is one relevant finding among several.

This is why tongue-tie care needs to begin with the whole feeding picture, not appearance alone.

For families, uncertainty can be exhausting. Feeding may feel painful, lengthy, stressful or simply unlike what was expected. For professionals, the challenge is to avoid both dismissing those experiences and assuming that one anatomical feature explains them.

Anatomy provides information. Function provides context.

What is tongue-tie?

Tongue-tie, clinically known as ankyloglossia, describes a variation of the lingual frenulum that may restrict tongue movement.

The lingual frenulum is normal tissue beneath the tongue and its appearance varies considerably between babies. It may be thin or thick, prominent or less obvious, and may attach at different points beneath the tongue.

The presence of a frenulum is therefore not, by itself, evidence that a baby has a clinically significant tongue restriction.

There is also no single universally accepted definition of ankyloglossia or single assessment method that can reliably determine whether an individual baby will experience feeding difficulties. Recent systematic reviews continue to identify substantial variation between assessment tools and diagnostic criteria (Necus et al., 2025; Dhar et al., 2026).

A meaningful assessment therefore needs to consider:

• the structure and appearance of the lingual frenulum

• tongue movement and function

• oral motor function

• feeding history

• direct observation of feeding where possible

• infant wellbeing and growth

• the feeding method being used

• the impact on the breastfeeding or feeding dyad

• other possible explanations for the symptoms

• the goals and priorities of the family.

A photograph cannot establish whether a tongue is functionally restricted. Even a very clear photograph shows anatomy, not how the tongue moves during feeding.

The Association of Tongue-tie Practitioners (ATP) provides information for families and a Find a Practitioner directory. Families should still check the practitioner's professional registration, qualifications, insurance and regulatory status where applicable.

You can also read more about how tongue-tie is assessed in babies.

What symptoms might be associated with tongue-tie?

A restrictive tongue movement may affect feeding mechanics in some babies, but symptoms are not specific to tongue-tie.

Breastfeeding or chestfeeding

Families may describe:

• difficulty achieving or maintaining a deep attachment

• repeated slipping to a shallow attachment

• nipple pain or damage

• nipple compression or an altered nipple shape after feeding

• clicking or loss of suction

• frequent or prolonged feeds

• difficulty managing milk flow

• poor breast drainage

• persistent breast fullness or recurrent blocked areas

• concerns about milk transfer

• a baby appearing unsettled during or after feeds

• difficulty maintaining a consistent feeding pattern.

These symptoms can be associated with restricted tongue function, but they can also occur for many other reasons.

Positioning, attachment, milk supply, breast anatomy, milk flow, infant muscle tone, prematurity, oral coordination, nasal obstruction, discomfort and other factors can all influence feeding.

A baby who is gaining weight can still be experiencing significant feeding difficulties. Weight gain is important information, but it does not measure parental pain, feeding duration, milk transfer efficiency or the sustainability of the feeding relationship.

Research examining breastfeeding difficulties associated with ankyloglossia has found maternal nipple pain and feeding difficulties in some affected dyads, but the evidence remains heterogeneous and diagnostic definitions vary (Bruney et al., 2022; Gismonti-Gaudêncio et al., 2025).

Bottle feeding

Tongue-tie is not exclusively a breastfeeding issue.

Bottle-feeding families may notice:

• difficulty maintaining a seal around the teat

• milk leaking from the mouth

• clicking

• frequent loss of suction

• prolonged feeds

• frequent pauses

• difficulty coordinating sucking, swallowing and breathing

• difficulty managing faster milk flow

• coughing, spluttering or stress during feeds

• excessive air intake

• fatigue during feeding

• difficulty progressing with different teat flows.

However, these signs also have many possible causes.

Teat shape and flow, bottle positioning, feeding pace, oral coordination, nasal congestion, prematurity, respiratory factors and infant neuromuscular development can all influence bottle feeding.

This is why bottle-feeding concerns deserve the same careful assessment as breastfeeding concerns. The feeding method does not determine whether a family deserves skilled support.

A symptom is not a diagnosis

One of the most important things families can understand about tongue-tie is that a symptom does not automatically identify its cause.

For example, clicking during a feed may occur because of reduced tongue function, but it can also occur because of positioning, attachment, milk flow or another oral-motor issue.

Similarly, reflux-like behaviours, unsettled feeding, prolonged feeds, wind, dribbling or frequent feeding should not automatically be interpreted as evidence of tongue-tie.

Even research investigating reflux and frenotomy remains inconclusive. A 2025 systematic review found that although some studies reported improvements in parent-reported reflux symptoms following frenotomy, the available evidence was limited by small studies, lack of control groups and other methodological problems (Patel et al., 2025).

This is why differential diagnosis matters.

What does differential diagnosis mean?

Differential diagnosis simply means considering other possible explanations before deciding that tongue-tie is responsible for the problem.

Depending on the presentation, these may include:

• positioning or attachment difficulties

• milk supply or milk-flow issues

• breast or teat-flow mismatch

• nasal congestion or obstruction

• prematurity or developmental immaturity

• oral thrush or other oral discomfort

• infant muscle tone differences

• neurological or neuromuscular factors

• craniofacial differences

• high or unusual palatal anatomy

• torticollis or positional asymmetry

• wider bodily tension

• feeding coordination difficulties

• gastrointestinal or respiratory concerns

• behavioural or sensory feeding difficulties.

This does not mean that a tongue restriction should be dismissed.

It means that the practitioner should ask whether the restriction provides a convincing explanation for the functional findings and whether other factors are also contributing.

Sometimes there will be one clear contributing factor.

Sometimes there will be several.

Sometimes the lingual frenulum will be an incidental anatomical finding and treatment will not be appropriate.

Why function-focused assessment matters

A function-focused assessment does not ask only:

> “Is there a frenulum?”

It asks:

> “How is this baby feeding, how is the tongue functioning, and what may be influencing this feeding experience?”

A comprehensive assessment considers both anatomy and function.

This is particularly important because assessment tools vary considerably. The 2025 systematic review by Necus et al. identified nine tools used to assess infant tongue structure and function and found considerable inconsistency in the parameters measured and the evidence supporting reliability and validity.

A newer 2026 systematic review similarly found substantial variation in diagnostic approaches and very-low-certainty evidence linking specific diagnostic findings with feeding difficulties (Dhar et al., 2026).

Assessment tools can therefore support clinical consistency and communication, but a score should not be treated as a diagnosis in isolation.

Assessment is not a score alone

A score may tell a practitioner something useful about anatomy or tongue movement.

It cannot independently establish:

• that the frenulum is causing the feeding problem

• that surgical treatment is required

• how much improvement a baby will experience following release

• whether another factor is contributing to the feeding difficulty.

Clinical reasoning is therefore essential.

Where appropriate, assessment may involve an infant feeding specialist, IBCLC, midwife, health visitor, GP, paediatrician, speech and language therapist or another relevant professional.

A multidisciplinary approach can be particularly valuable where feeding difficulties are complex or where there are additional developmental, neurological, respiratory or musculoskeletal concerns.

You can read more about what an infant feeding specialist does.

Does every tongue-tie need treatment?

No.

Some babies have a visible lingual frenulum and feed effectively without intervention.

NICE recognises that many tongue-ties are asymptomatic and cause no problems, and recommends careful assessment to establish whether the frenulum is actually interfering with feeding before considering division (NICE, 2005).

The decision to intervene should therefore be based on the individual baby rather than the appearance of the frenulum alone.

This is particularly important because the increasing recognition of tongue-tie has occurred alongside continuing uncertainty about diagnostic definitions and treatment outcomes.

A 2025 systematic review found that approximately seven out of ten infants included in studies of breastfeeding difficulties did not have ankyloglossia identified as the explanation for their feeding difficulties, highlighting the importance of considering other causes before surgical referral (Gismonti-Gaudêncio et al., 2025).

Conservative management is active care

Conservative management does not mean doing nothing.

It may include:

• skilled breastfeeding or chestfeeding support

• attachment and positioning adjustments

• assessment of milk transfer

• consideration of milk supply and flow

• responsive and paced bottle-feeding support

• consideration of teat flow and positioning

• support with infant oral-motor skills

• management of contributing discomfort

• monitoring over time

• reassessment where symptoms persist.

Sometimes these measures substantially improve feeding without surgery.

Sometimes they identify that a restrictive frenulum remains a relevant factor despite appropriate feeding support.

Sometimes a family simply needs time to understand the situation before deciding what to do.

There should be no expectation that a family must make a surgical decision during a single appointment.

It is also reasonable for families to seek a second opinion if they remain uncertain, particularly when recommendations have been based only on a photograph, an oral examination without feeding observation, or a single symptom.

Good care should leave families feeling heard and able to ask questions.

When might frenulotomy be considered?

In the UK, the surgical division of a restrictive lingual frenulum in an infant is commonly described as a frenulotomy, although terminology varies and terms such as frenotomy or frenectomy may also be used in the literature.

The key question is not whether the procedure exists.

It is whether it is appropriate for this particular baby.

Where a restrictive lingual frenulum has been identified alongside clinically significant functional feeding difficulties, and appropriate conservative support has not adequately addressed those difficulties, a discussion about surgical release may be appropriate.

That discussion should include:

• what has been identified

• how the findings relate to feeding

• what other causes have been considered

• what conservative options remain

• the potential benefits

• the limitations of the evidence

• potential complications

• what the procedure involves

• what aftercare will be required

• what happens if feeding does not improve as expected.

Frenulotomy should not be presented as a guaranteed solution.

What does the evidence say about frenulotomy?

The evidence is strongest for some short-term breastfeeding outcomes, particularly maternal nipple pain.

The 2017 Cochrane review found that frenotomy may reduce breastfeeding mothers' nipple pain in the short term, but concluded that the evidence for improvement in infant breastfeeding outcomes was inconsistent and based on small studies with methodological limitations (O'Shea et al., 2017).

A later systematic review and meta-analysis found improvements in breastfeeding difficulty scores and maternal pain following frenotomy, although considerable variation existed between studies and assessment methods (Bruney et al., 2022).

The UK FROSTTIE randomised trial compared frenotomy plus breastfeeding support with breastfeeding support alone. Recruitment difficulties and substantial crossover between treatment groups meant that the trial could not provide a definitive answer about breastfeeding continuation at three months (Knight et al., 2023).

This distinction matters.

Evidence that a procedure can improve a particular outcome in some circumstances is not the same as evidence that it will resolve every feeding difficulty.

Evidence for bottle feeding is considerably less developed than the evidence relating to breastfeeding. It would therefore be inappropriate to promise that releasing a frenulum will resolve bottle-feeding symptoms without first assessing the wider feeding situation.

What are the different surgical techniques?

Several techniques have been described for lingual frenulum division.

Scissors

Conventional scissors frenotomy remains widely used for infants.

NICE describes infant division using sharp, blunt-ended scissors, with feeding commonly resumed immediately afterwards (NICE, 2005).

Laser

Laser techniques are increasingly available and are sometimes promoted as being more precise or producing less bleeding.

However, the available evidence does not establish that laser produces superior feeding outcomes compared with conventional techniques.

A systematic review comparing conventional, laser and other surgical techniques found substantial heterogeneity and no clear evidence that one technique was superior overall (Mills et al., 2020).

A more recent systematic review similarly found insufficient evidence to establish one surgical technique as universally superior (Dhar et al., 2026).

Laser is therefore a technique, not automatically an indication that treatment will be better.

Electrosurgical techniques

Electrosurgical approaches have also been described.

As with laser, the choice of technique should take into account the practitioner's training, clinical environment, equipment, infant age and presentation, and the evidence available for the particular procedure.

More extensive frenuloplasty procedures

In some older infants and children, a more extensive procedure such as a frenuloplasty may be considered rather than a simple infant frenotomy.

This is not usually equivalent to the straightforward infant procedure and may involve different surgical considerations, anaesthesia and postoperative management.

Families should therefore ask exactly what procedure is being proposed rather than assuming that all tongue-tie releases are the same.

Overall, current evidence does not demonstrate a clear universal advantage of one technique over another (Mills et al., 2020; Dhar et al., 2026).

What happens after a tongue-tie release?

The procedure is only one part of tongue-tie care.

Releasing a restriction changes the mechanical environment beneath the tongue. It does not automatically teach the tongue how to use its newly available movement.

This is why aftercare and follow-up deserve proper attention.

Immediately after a procedure, the priority is appropriate observation, feeding support and safety-netting.

Over the following days and weeks, families may need support with:

• feeding changes

• attachment

• milk transfer

• bottle-feeding mechanics

• infant comfort

• tongue movement

• developing more effective tongue function

• maintaining feeding confidence

• wound healing

• identifying complications or concerns.

The aim is not simply to have a wound that has healed.

The aim is to support the infant's function and feeding as the healing process progresses.

Wound care after tongue-tie release

After a frenulotomy, the wound beneath the tongue needs time to heal.

Families should be given clear information about normal healing, what to expect and when to seek further advice. This is different from deliberately manipulating the wound in an attempt to prevent it from healing.

A healing wound is part of the body's normal repair process. Families should not be encouraged to repeatedly pull the wound apart, scrape it, massage it aggressively or otherwise disrupt the healing tissue unless there is a specific clinical indication and this has been recommended by the clinician responsible for the procedure.

In particular, postoperative stretching exercises that involve repeatedly opening or disrupting the wound to prevent reattachment are not supported by good evidence.

The 2024 American Academy of Pediatrics clinical report specifically states that postoperative stretching exercises are not evidence-based and are not recommended. It also highlights the potential for these interventions to contribute to oral aversion (Thomas et al., 2024).

This is important because the terms "aftercare", "stretches", "exercises" and "wound care" are sometimes used interchangeably online, when they do not necessarily mean the same thing.

Wound care should support normal healing rather than repeatedly traumatising the surgical site.

Healing is not the same as reattachment

It is understandable that families may be concerned about the possibility of the frenulum "reattaching" after release.

However, preventing normal wound healing by repeatedly opening the surgical site is not the same as supporting good functional recovery.

The evidence surrounding postoperative wound management remains limited. A 2024 systematic review identified substantial variation in the interventions used, including the frequency and duration of postoperative exercises. Only a small number of studies examined the relationship between postoperative care and recovery outcomes, and the authors concluded that further research is needed to establish the most effective approach (Ghaheri et al., 2024).

This means that families should be cautious about claims that a particular wound-stretching routine is essential, that failure to perform stretches will inevitably cause reattachment, or that a particular appearance of the healing wound proves that the procedure has failed.

A 2025 prospective study investigated stretching following infant frenotomy and reported outcomes from stretching and non-stretching groups. However, adherence to the stretching regimen was variable and the study design cannot establish that routine wound stretching is necessary for all infants (Miller et al., 2025).

The evidence therefore does not justify presenting wound stretching as a universal requirement.

What can aftercare include?

Appropriate aftercare may include:

• following the individual practitioner's wound-care and safety-netting advice

• supporting comfortable feeding

• observing changes in feeding following the procedure

• monitoring infant wellbeing and hydration

• addressing any continuing breastfeeding or bottle-feeding difficulties

• supporting functional tongue movement where clinically appropriate

• monitoring recovery over time

• seeking further assessment if feeding difficulties persist or new concerns develop.

The purpose of follow-up is therefore broader than simply inspecting the wound.

It is to consider how the baby is recovering and whether the functional reason for treatment is improving.

Where exercises or movement activities are recommended, families should understand whether these are intended to support functional movement and feeding or whether they involve direct manipulation of the healing wound. These are not necessarily the same thing.

Functional rehabilitation after release

Releasing a restrictive frenulum changes the available range of movement. It does not automatically mean that a baby will immediately use that movement efficiently.

A baby may have developed compensatory patterns before the procedure. Depending on the individual presentation, these may involve the tongue, jaw, lips, cheeks, head and neck or wider body movement.

This is where appropriate post-procedure support can be useful.

The aim should be to support functional recovery rather than repeatedly disturb the surgical wound.

Feeding support may help a baby adapt to changes in tongue movement and may identify whether further assessment is needed. In some babies, consideration of oral-motor function, muscle tone, asymmetry or wider body tension may also be appropriate.

There is currently insufficient evidence to establish one universal post-frenotomy rehabilitation programme for all babies. The 2024 systematic review found considerable variation in postoperative interventions and concluded that further research is needed to determine the most effective approach (Ghaheri et al., 2024).

This uncertainty should not be interpreted as meaning that follow-up is unnecessary.

It means that aftercare should be individualised rather than based on a single mandatory routine.

What about tongue exercises?

The term "tongue exercises" can describe very different things.

Some activities may be intended to encourage functional tongue movement or support feeding skills. These are different from exercises that deliberately pull apart or manipulate a healing surgical wound.

Families should therefore ask exactly what they have been advised to do, why they are being asked to do it and whether the activity involves the healing wound.

The evidence for postoperative stretching is particularly important here.

The American Academy of Pediatrics clinical report states that postoperative stretching exercises are not evidence-based and are not recommended, specifically in relation to exercises in which parents repeatedly open the wound to prevent reattachment (Thomas et al., 2024).

The available research does not currently establish a universal requirement for this type of wound manipulation. A 2025 prospective study provides additional data on stretching, but its findings should be interpreted cautiously because of the study design and variable adherence to the prescribed regimen (Miller et al., 2025).

For families, this means that "you must stretch the wound or the tongue-tie will grow back" is an overly certain statement that is not supported by the current evidence.

The focus should remain on safe healing, feeding and functional recovery.

What about body tension and body therapies?

The tongue does not function in isolation.

Feeding involves coordinated movement through the jaw, neck, head, respiratory system and wider body. Babies may also develop compensatory postures or increased muscle tension for reasons that have nothing to do with tongue-tie.

For some babies, assessment of wider movement, asymmetry or muscular tension may therefore be clinically useful.

Depending on the individual findings, families may be advised to seek appropriate support from professionals such as physiotherapists or other suitably trained practitioners.

Body-based therapies should complement, rather than replace, appropriate medical, feeding or surgical assessment.

It is also important to distinguish clinical reasoning from evidence claims.

Research into manual therapies, bodywork and post-frenotomy rehabilitation remains considerably less developed than research into breastfeeding support and frenotomy itself. These approaches should therefore not be presented as proven treatments for ankyloglossia.

Instead, they may form part of an individualised plan where a baby's assessment indicates that wider tension, movement or postural factors may be influencing feeding.

Aftercare is not just about the wound

One of the most common misunderstandings about tongue-tie release is that the procedure marks the end of the problem.

In reality, it may be the point at which a new phase of support begins.

Families should know what to expect from wound healing and should receive clear information about when and how to seek help.

They should also know who to contact if feeding becomes more difficult, if their baby is unusually unsettled, if there are concerns about bleeding or healing, or if they are worried about their baby's wellbeing.

Most importantly, families should not be left with the assumption that feeding must immediately become perfect.

Some babies adapt quickly.

Others need time, feeding support and, where indicated, additional assessment of oral function or wider physical factors.

You can read more in my guide to what to expect after a tongue-tie release.

Choosing a tongue-tie practitioner

Choosing a practitioner is an important part of the process.

Families may wish to ask:

• What professional registration do you hold?

• Are you insured for the service you provide?

• Are you appropriately regulated for the procedure you perform?

• How do you assess tongue function?

• Do you observe feeding?

• Do you consider bottle as well as breastfeeding?

• What other causes of feeding difficulty do you consider?

• What happens if you do not think tongue-tie is the main problem?

• What treatment options are available besides surgery?

• What surgical technique do you use?

• What are the risks and limitations?

• What aftercare and follow-up do you provide?

• What happens if feeding does not improve?

The ATP Find a Practitioner directory can help families identify practitioners and services in their area.

The ATP is a professional organisation and directory rather than a regulator. Families should still independently check the practitioner's professional registration, qualifications, insurance and regulatory status where applicable.

What about lip-ties and other oral restrictions?

The term "lip-tie" is widely used online, but the presence of a prominent upper lip frenulum is common infant anatomy.

Evidence supporting routine surgical release of an upper lip frenulum for breastfeeding difficulties is poor. A systematic review found no randomised controlled trials demonstrating benefit from routine upper lip frenulum release and questioned the reliability of commonly used classification systems (Nakhash et al., 2019).

This is another example of why appearance should not be confused with functional diagnosis.

A baby can have a prominent frenulum without requiring surgery.

What if I am still unsure?

It is reasonable to take time.

Families do not have to choose surgery simply because a frenulum has been identified.

It is also reasonable to seek another opinion if the assessment did not explain how the finding relates to feeding, if no alternatives were discussed, or if you feel pressured into making a decision.

A good consultation should allow you to understand:

1. what has been found

2. what it may mean functionally

3. what else could be contributing

4. what can be tried without surgery

5. what the evidence says about treatment

6. what the procedure involves if it is being considered

7. what aftercare would look like

8. what happens if the expected improvement does not occur.

The goal is not to persuade a family towards or away from treatment.

The goal is informed decision-making.

How D-Restricted Ltd® approaches tongue-tie care

At D-Restricted Ltd®, tongue-tie assessment is considered alongside the wider feeding picture.

Assessment includes consideration of oral anatomy, tongue movement and feeding function, with breastfeeding, chestfeeding and bottle feeding all included within infant feeding support.

Where a restrictive tongue-tie is identified, the discussion about treatment is individualised. Surgical release is not presented as an automatic response to the presence of a frenulum, and there is no obligation to proceed with a procedure during an assessment appointment.

Where frenulotomy is undertaken, ongoing support is also provided rather than treating the procedure as the end of care.

You can find out more about D-Restricted Ltd® tongue-tie assessment, surgical release and aftercare.

You may also find my tongue-tie symptom guide useful when deciding whether a feeding assessment may be appropriate. It is not a diagnostic tool, but it can help families organise the symptoms they are experiencing.

For families who need support with feeding whether or not tongue-tie is involved, infant feeding support is also available.

The important message

Tongue-tie is neither something that should automatically be treated nor something that should automatically be dismissed.

A visible frenulum may be completely compatible with comfortable, effective feeding.

A restrictive frenulum may also be an important contributor to significant feeding difficulties.

The difference lies in function.

Good tongue-tie care therefore starts with listening to the feeding experience, assessing the infant properly, considering alternative explanations and discussing treatment options honestly.

Where surgery is appropriate, the procedure is only one part of the journey.

Feeding support, follow-up, appropriate rehabilitation and consideration of wider physical factors may all have a role in helping a baby make the most of their available tongue movement.

Aftercare should support healing, not deliberately disrupt it.

For families, the aim should be neither fear nor pressure.

It should be clarity.

Anatomy provides information.

Function provides context.

And every feeding journey deserves support, compassion and reassurance.
