Tongue Tie in Babies: When Does It Need Treatment?

What is tongue tie?

Under the tongue is a thin fold of tissue called the frenulum. In tongue tie (ankyloglossia) this band is short, thick or attached close to the tip of the tongue, so the tongue cannot lift, stretch forward or move side to side as freely as usual. It is present from birth, more common in boys, and sometimes runs in families.

How can you tell if a baby has tongue tie?

Signs in the baby:

• difficulty latching on or staying on the breast;
• a clicking sound while feeding;
• feeding for a long time, needing frequent feeds or seeming hungry soon after;
• poor weight gain;
• a tongue tip that looks notched or heart-shaped when the baby cries;
• a tongue that cannot lift to the roof of the mouth or poke out past the lips.

Signs in the mother:

• sore, cracked or flattened nipples after feeds;
• low milk supply or blocked ducts from poor drainage.

None of these signs is specific to tongue tie, which is why a check by someone experienced in infant feeding matters before any procedure.

Does tongue tie always cause problems?

No. Many babies with a visible frenulum feed well. Feeding support, positioning and latch advice solve many problems on their own. Treatment is considered when a tie is clearly restricting tongue movement and feeding difficulties continue despite that help.

What does the evidence say?

A Cochrane review of trials in newborns found that frenotomy reduced mothers’ nipple pain in the short term, while the effect on the baby’s feeding was less consistent between studies. Serious complications are rare when the procedure is done by a trained clinician. In older children, evidence that tongue tie causes speech problems is limited, so release for speech is decided case by case with a speech therapist.

What is frenotomy and how is it done?

	Frenotomy (young babies)	Frenuloplasty (older children and adults)
Typical age	First weeks or months	Toddlers, children, adults
Anaesthesia	Often none or local	Usually general anaesthesia in children
What is done	Thin band snipped with sterile scissors	Band released and the wound stitched
Time	A few seconds to minutes	Under an hour
Feeding afterwards	Straight away	Soft food for a few days
Bleeding	A few drops	Minimal; stitches dissolve

After a frenotomy, the baby is usually fed straight away, which helps settle them and stop any bleeding.

Recovery and aftercare

• A white or yellow patch under the tongue for a week or two is normal healing, not infection.
• Mild fussiness for a day is common; simple pain relief may be advised for older babies.
• Continue feeding support; latch can take a few days to improve as the baby learns to use the tongue.
• In older children, tongue stretching exercises may be advised to stop the tissue tightening again.

Seek help for bleeding that does not stop with gentle pressure, poor feeding, fever or a baby who seems unwell.

Myths about tongue tie

• “Every tongue tie must be cut at birth.” Many need no treatment.
• “Tongue tie always causes speech problems.” Most children with tongue tie speak normally.
• “Frenotomy fixes all feeding problems.” Feeding difficulties have many causes; support is still important.
• “It is a major operation.” In young babies it is a quick, simple procedure.

When should you see a doctor?

See a doctor, lactation consultant or surgeon if your baby struggles to latch, feeds very slowly, is not gaining weight, or if breastfeeding is painful despite help with positioning. For older children, a speech therapist’s opinion is useful before deciding on surgery.

What to ask

• Is this tongue tie actually causing my baby’s feeding problem?
• Would feeding support alone help first?
• Which procedure is advised, and does it need anaesthesia?
• What aftercare and follow-up do you recommend?

For assessment and the procedure, see tongue tie surgery. Children’s injuries to the mouth and face are also treated by plastic surgeons; read will a face cut leave a scar or see reconstructive surgery.
