What is it?
Tongue-tie means that the band of tissue joining the underside of the tongue to the floor of the mouth is short, thick, or sits too close to the tip of the tongue. It is present from birth and is not a disease in itself. What matters is not how the band looks, but how far the tongue can actually move.
The assessment looks at whether the tongue reaches the palate, can move out to the sides and can come forward over the lower teeth, and whether the tip takes on a heart-shaped notch as it comes out. In a baby, feeding information is added to this: how the nipple is latched on to, clicking sounds during feeding, feeds taking longer and weight gain are all weighed up together.
In recent years diagnoses of tongue-tie and division procedures have risen noticeably, and that rise has opened a debate among clinicians about overdiagnosis. Not every band that looks short causes a problem with function. If function is normal, watching is enough, and the decision to intervene rests on a real problem that has shown itself, not on appearance.
Signs
You will not necessarily have all of these at once.
Why does it happen?
- 01
A result of development before birth
While the baby is in the womb, the process that separates the tongue from the floor of the mouth does not finish, and the band stays short or thick. This is not down to anything done or not done during pregnancy; that is the answer to the guilt question families ask most often.
- 02
A tendency that runs in the family
Tongue-tie can be seen in more than one person in the same family. If a brother, sister or parent has a similar band, it is sensible for this area to be looked at more carefully at the newborn check.
- 03
Where the band sits and how it is built
A band that sits close to the tip of the tongue and is tight restricts movement more; one that sits further back and is loose usually causes no trouble at all. That is why the same description of a short band can mean very different things in two babies.
- 04
Rare conditions that go with it
Tongue-tie can also appear as part of certain conditions that are present from birth. In those cases it is not the only finding; there are other findings involving the development of the palate, lip or face. A paediatrician assesses this distinction.
How does it progress?
- 1
A band that does not affect function
The band is visible, but the tongue reaches the palate and moves out to the sides. Feeding and speech are unaffected. No procedure is advised in this group; watching is enough.
- 2
A band that makes breastfeeding difficult
The baby cannot latch deeply on to the nipple, there are clicking sounds during feeding, feeds take longer and weight gain slows; the mother may have sore, cracked nipples. Improvement is looked for first with breastfeeding support.
- 3
A band that clearly restricts movement
The tip of the tongue takes on a heart-shaped notch as it comes out, the tongue does not reach the palate and cannot come forward over the lower teeth. Clearing food debris and making certain sounds can become difficult; it is mainly in this group that a procedure comes up.
- 4
A posterior (hidden) band
There is no visible band; the restriction lies under the lining. This is the most disputed group to diagnose, and the decision rests on repeated assessment of function rather than on a single view at one examination.
How is it treated?
The decision itself is the first step of treatment. In a baby the assessment is usually shared: the breastfeeding support team and the paediatrician follow the feeding, while the dentist assesses tongue movement and the structures inside the mouth. There is a considerable number of babies whose problem clears once positioning and latch are put right; in that case a division procedure is not advised.
If a procedure is decided on, the method depends on age. In a newborn a thin band is released with a small, quick cut, and the baby can feed straight afterwards. In an older child and in an adult the band is thicker, so the procedure is carried out under local anaesthetic and needs stitches. Tongue movements are advised during healing to reduce the chance of the tissue reattaching.
Expectations need to be talked through from the start. The procedure widens the range of tongue movement; sounds correcting themselves is not expected in every child, and speech and language therapy is carried out separately where it is needed. Bleeding, infection and reattachment during healing can occur, even if rarely, so the follow-up appointment should not be skipped.
- If your baby is not gaining weight, has fewer wet nappies, or tires before finishing a feed, see a clinician the same week.
- Bleeding that does not stop after the procedure, a fever, or refusing to feed altogether are not expected findings.
- Tongue movement that has become restricted later in adult life is not explained by tongue-tie; it needs a separate assessment.
How is it prevented?
- Tongue-tie is present from birth and cannot be prevented; what can be done is to notice it early and to avoid an unnecessary procedure.
- If breastfeeding is difficult, get support with positioning and latch first; tongue-tie is not the cause of every feeding problem.
- Ask for an assessment of function before any decision; a decision based on the look of the band alone is not enough.
- If a procedure has been carried out, do the tongue movements you were advised to do and go to the follow-up appointment; the tissue can reattach during healing.
Frequently asked questions
- Does every tongue-tie need to be cut?
- No. A large share of bands that look short do not affect breastfeeding, speech or mouth cleaning, and in that case watching is enough. A procedure is considered when there is a measurable problem and once that problem has been shown to be linked to the band. That is exactly why the rise in diagnoses and division procedures is being debated.
- Is tongue-tie the cause of a speech problem?
- Making certain sounds needs the tip of the tongue to reach the palate, and a clear restriction can make that difficult. But there are many other causes of delayed speech, and the procedure on its own is not expected to correct speech. It is sensible for the assessment to be done together with a speech and language therapist.
- Is there a right age for the procedure?
- There is no single set age. Where the band is preventing breastfeeding, the decision may be made in the first weeks; procedures carried out because of speech or cleaning are planned for a time when the child can cooperate. It can be done in adults too, and what is expected there is a wider range of tongue movement.
