Tongue-tie, known medically as ankyloglossia, is when the small band of tissue under the tongue, the frenulum, is short or tight enough to limit how far the tongue can move. It is common, affecting an estimated 1 in 20 babies, but the most important fact for worried parents is that most babies with a tongue-tie feed perfectly well. Around half of breastfeeding babies with a tongue-tie have no feeding problem at all. Tongue-tie only needs treating when it is genuinely getting in the way of feeding, and the decision deserves a careful, unhurried look rather than a reflex to act.
Key takeaways
- Tongue-tie affects roughly 1 in 20 babies, and many never have any problem from it.
- About half of breastfeeding babies with a tongue-tie feed without difficulty.
- It only needs treating when it is clearly causing feeding problems, not because it is present.
- A feeding assessment and lactation support come before any procedure.
- When feeding is genuinely affected, a simple release (frenotomy) can help, and most parents report improvement.
The one question that matters: is it actually affecting feeding?
The single most important question in tongue-tie is not whether a tie can be seen, but whether it is causing a feeding problem. A tongue-tie that is visible but not interfering with feeding generally needs nothing more than reassurance. The appearance of the frenulum on its own is a poor guide, because plenty of babies with a noticeable tie feed beautifully. The decision rests on function, how the baby latches, feeds, gains weight and settles, and on the mother's comfort during breastfeeding, not on a photograph of the tissue.
Signs a tongue-tie may be affecting feeding
In breastfeeding, the signs can include difficulty latching or staying on, feeds that take a very long time, clicking sounds, poor weight gain, and ongoing nipple pain or damage for the mother. Some babies are unsettled and seem hungry soon after feeding. Bottle-fed babies may dribble, take a long time, or be windy. Many of these signs have other causes too, which is exactly why a proper feeding assessment matters before assuming the tongue is to blame. A lactation consultant or experienced clinician can watch a full feed and look at positioning and attachment first, since adjusting those alone often solves the problem.
What the evidence says about treatment
When a tongue-tie is genuinely affecting feeding, a frenotomy, a quick release of the tight band, can help. In studies, the large majority of parents, around 9 in 10, report an improvement in breastfeeding afterwards, with less nipple pain and a better latch. At the same time, the evidence does not support releasing every tongue-tie, because most babies do not need it. Leading paediatric guidance encourages trying feeding support and positioning changes first, and reserving the procedure for babies where feeding is clearly affected. In young babies the frenulum under the tongue is thin and has little blood supply, so a release is usually quick, with the baby able to feed straight afterwards, though as with any procedure it carries small risks worth discussing.
Does tongue-tie affect speech or teeth later?
Many parents worry about speech and dental effects down the track. For most children a tongue-tie does not cause speech problems, and the tongue often stretches with age. Occasionally an older child with a tight tie has difficulty with certain sounds or with keeping the front teeth clean, and a release can be considered then, guided by a speech pathologist or dentist. There is no need to treat a symptom-free tongue-tie in infancy on the assumption it will cause problems later, since most will not.

Frequently asked questions
Does every tongue-tie need to be cut?
No. Most babies with a tongue-tie feed well and need nothing. A release is considered only when a tongue-tie is clearly affecting feeding and feeding support has not resolved it.
Will tongue-tie cause speech problems?
Usually not. Most children with a tongue-tie develop normal speech. If an older child has difficulty with specific sounds, a speech pathologist can advise whether a release would help.
What should we try before a procedure?
A feeding assessment with a lactation consultant or experienced clinician, looking at positioning and attachment. Adjusting these often fixes the problem without any procedure.
Is the release painful for the baby?
The frenulum in young babies is thin with little blood supply, so the procedure is quick and babies can usually feed straight afterwards. Your clinician will explain the small risks involved.
When to see a clinician
Seek a feeding assessment if breastfeeding is persistently painful, your baby struggles to latch or gain weight, or feeds are very long and unsettled. These deserve support whether or not a tongue-tie is found. For related reading, see our guides on natal and neonatal teeth, your child's first dental visit, and cleft lip and palate dental care.
