Tongue-tie, medically known as ankyloglossia, is a condition in which the strip of tissue that connects the underside of the tongue to the floor of the mouth—the lingual frenulum—is unusually tight or restrictive. This tissue can limit tongue movement, causing some babies with tongue-tie to have difficulty breastfeeding or bottle-feeding.
Tongue-tie is relatively common, but not every baby with a tongue-tie needs treatment. Some babies have a restrictive-looking frenulum but feed normally and grow well. Current guidance recommends treatment only when a restrictive frenulum is causing feeding difficulties that do not improve with appropriate feeding support.
For parents, the most important message is simple: the appearance of a restrictive frenulum under your baby’s tongue does not automatically mean something is wrong. The baby’s feeding, tongue movement, weight gain, and overall health are more important considerations.
The lingual frenulum is a normal band of tissue under the tongue, which helps connect the tongue to the floor of the mouth.
In some babies, this tissue is shorter, tighter, or less flexible than usual, restricting tongue movement. This condition is known as tongue-tie. The degree of restriction can vary: some babies have mild restriction and no problems at all, while others have difficulty lifting, extending, or moving the tongue from side to side, which interferes with feeding.
Also, no universally accepted test or criteria exist for diagnosing tongue-tie: Appearance and tongue function, particularly how the baby feeds, are what healthcare professionals consider.
Tongue-tie is present from birth and occurs when the tissue under the tongue develops in a way that restricts the tongue’s movement. It is not caused by something a parent did during pregnancy or after the baby was born. Tongue-tie varies in appearance and degree.
Possible signs include the following:
A breastfeeding parent may also experience sore, cracked, or painful nipples, particularly when the baby’s latch is poor. However, these symptoms do not prove that tongue-tie is the cause. Feeding difficulties are common in newborns and can have many causes.
Successful breastfeeding requires the baby to coordinate tongue movement, sucking, and swallowing. The tongue helps the baby maintain an effective latch and remove milk from the breast.
Restricted tongue movement may prevent babies from latching properly or transferring milk efficiently. This may lead to prolonged feeds, clicking sounds, nipple pain, or concerns about milk intake. However, it should be noted that breastfeeding is complex and can be affected by several factors, including the baby’s ability to suck, oral anatomy, the mother’s breast anatomy, positioning, and latch. A recent study from Hyderabad, India, found that untreated tongue-tie alone was not associated with differences in breastfeeding continuation or infant weight gain. The researchers concluded that breastfeeding difficulties should be approached by considering multiple possible causes rather than focusing only on tongue-tie.
Tongue movement can also affect bottle-feeding because some babies may struggle to create an effective seal around the bottle nipple or coordinate sucking and swallowing. However, as with breastfeeding, these symptoms can have other causes. A healthcare professional should assess the baby’s overall feeding rather than assuming tongue-tie is responsible.
There is no blood test, scan, or routine laboratory test for tongue-tie. The paediatrician assesses the baby’s mouth to check its movement. For a baby with feeding problems, the assessment should include observation of a feeding session.
A complete breastfeeding assessment is recommended in babies with ineffective breastfeeding before treatment. This can involve a paediatrician, lactation professional, and, when appropriate, an ear, nose, and throat (ENT) specialist or other qualified clinician. This is important because a baby with a restrictive frenulum may not have a functional problem. Reports suggest that fewer than half of infants with physical findings consistent with tongue-tie had breastfeeding difficulties.
The simple answer is no. If the baby feeds properly and comfortably, gains weight appropriately, and possesses normal tongue function, treatment is not necessary. It is important to distinguish a restrictive frenulum that is simply present from symptomatic tongue-tie with breastfeeding problems that have not improved with lactation support, to avoid unnecessary treatment.
Feeding support is often an important first step. A trained lactation professional can assess the baby’s position at the breast, latch, sucking pattern, milk transfer, feeding frequency and duration, maternal nipple pain, baby’s weight gain, and whether another feeding problem may be present. Small changes in positioning and latch can sometimes make a significant difference. However, persistent feeding problems deserve proper assessment.
If your baby is struggling to feed, has fewer wet diapers than expected, seems unusually sleepy during feeds, or is not gaining weight appropriately, contact your paediatrician promptly.
Frenotomy is recommended if a baby has symptomatic tongue-tie and continued feeding problems despite appropriate support. In this procedure, the restrictive frenulum is released, allowing the tongue greater freedom of movement. This procedure is generally quick in young babies and is usually performed without an anaesthetic in young infants. The exact procedure and pain-control approach depend on the age, clinical circumstances, and healthcare setting. Parents should discuss the procedure with the clinician performing it, including the expected benefits, risks, aftercare, and alternatives.
In a few studies, frenotomy improved breastfeeding self-efficacy, maternal nipple pain, and some measures of breastfeeding quality. However, these outcomes also depended on the degree of restriction; thus, it is recommended that this procedure be reserved for infants with symptomatic tongue-tie, rather than performing it just because the frenulum looks tight.
No procedure is risk-free. Frenotomy is considered a minor procedure; however, some potential complications can include bleeding, infection, pain, or injury to nearby tissues. Feeding problems may also continue if tongue-tie was not the main cause. Parents should be cautious about claims that tongue-tie surgery will automatically prevent future speech problems or sleep apnea, as no supportive evidence exists that frenotomy prevents future speech articulation problems or sleep apnea.
This is one of the most common concerns among parents. Restricted tongue movements do not automatically mean a child will develop a speech problem. The evidence that infant frenotomy prevents future speech problems is insufficient. Frenotomy is not recommended solely to prevent future speech articulation problems.
Some older children with restricted tongue movement may struggle to produce particular sounds. However, speech development is complex, and having a restrictive frenulum does not automatically cause a speech disorder. For older children with speech problems, a speech-language pathologist must examine the child’s speech sounds and oral-motor function before deciding to proceed with surgery.
Laser frenotomy is being widely advertised; however, there is no evidence that it is superior to traditional frenotomy (which uses scissors). Parents should focus less on which procedure is better; rather, they should determine whether the healthcare professional is experienced enough to make the appropriate diagnosis and whether treatment is required.
Talk to your baby’s paediatrician or another qualified healthcare professional if you notice the following:
If your baby is not feeding adequately or is losing weight, do not wait for a tongue-tie assessment alone. Babies can become dehydrated or develop nutritional problems for many reasons, and prompt evaluation is important.
Tongue-tie can be a genuine cause for feeding difficulties in some babies, but a restrictive frenulum does not automatically mean there is a medical problem.
The most useful questions to discuss with the paediatrician:
These questions can help parents decide based on the baby’s actual needs rather than appearance alone.
Tongue-tie, or ankyloglossia, is a condition present from birth in which a restrictive lingual frenulum limits tongue movement, possibly contributing to breastfeeding difficulties in some babies. However, many babies with tongue-tie feed normally and do not require treatment.
Babies with feeding difficulties should be carefully assessed for feeding and tongue function, rather than immediately deciding on surgery. Lactation support can be valuable, and frenotomy may be appropriate when a restrictive frenulum is clearly contributing to persistent feeding problems.
Parents should not feel guilty if breastfeeding is difficult. Feeding problems are common, and tongue-tie is only one possible explanation. Working with your paediatrician and a qualified lactation or feeding professional can help identify the cause and choose the safest approach for your baby.

Tongue-tie, or ankyloglossia, occurs when the tissue connecting the underside of the tongue to the floor of the mouth is unusually tight or restrictive. It can limit tongue movement and may interfere with feeding in some babies.
Possible signs include difficulty lifting or extending the tongue, trouble latching, clicking sounds during feeding, milk leaking from the mouth, prolonged feeds and poor weight gain. These symptoms can have other causes, so a healthcare professional should assess your baby.
Restricted tongue movement may affect a baby’s ability to latch and transfer milk efficiently. This can lead to prolonged feeds, clicking sounds and maternal nipple pain. However, breastfeeding difficulties can have several possible causes.
No. Babies who feed comfortably, gain weight appropriately and have adequate tongue movement generally do not need treatment. Frenotomy may be considered when a restrictive frenulum contributes to persistent feeding difficulties despite appropriate feeding support.
Frenotomy has improved maternal nipple pain, breastfeeding self-efficacy and some measures of breastfeeding quality in certain studies. However, the benefits vary, and the procedure is not automatically necessary for every baby with a restrictive frenulum.
Frenotomy may cause bleeding, infection, pain or injury to nearby tissues. Feeding difficulties may also continue if tongue-tie was not their main cause. Parents should discuss the expected benefits, risks and alternatives with the treating clinician.
There is no evidence that laser frenotomy is superior to traditional frenotomy using scissors. The experience of the healthcare professional, accurate diagnosis and whether treatment is actually required are important considerations.
A restrictive frenulum does not automatically cause speech problems. Evidence that infant frenotomy prevents future speech difficulties is insufficient. If an older child has speech concerns, a speech-language pathologist should assess speech sounds and oral-motor function before surgery is considered.
