Tongue-tie

Also called Ankyloglossia

Tongue-tie is when the strip of skin connecting a baby's tongue to the bottom of the mouth (the frenulum) is shorter than usual. It can stop the tongue moving freely. Some babies have no problems, but for others it can make breastfeeding or bottle feeding harder.

What it is

If it does not cause problems, no treatment is needed.

If it affects feeding, a quick procedure to cut the frenulum (tongue-tie division) can be done, often without anaesthetic in young babies. Feeding support also helps.

Common signs

  • Difficulty latching on to the breast
  • Feeding for a long time or often
  • Clicking sounds when feeding
  • Poor weight gain
  • Sore or damaged nipples for the person breastfeeding
  • A heart-shaped tongue tip

How it is usually diagnosed

  • Examination of the baby's mouth
  • Feeding assessment

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Midwife, health visitor or feeding specialist notes
  • Procedure notes
  • Weight charts

Questions to ask your doctor

  • Is the tongue-tie affecting feeding?
  • Would division help?
  • What feeding support is available?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • A baby who is not feeding, has very few wet nappies or is very sleepy: get urgent help the same day
