What is tongue-tie?

Tongue-tie (ankyloglossia) is when the strip of skin connecting the tongue to the floor of the mouth is shorter or tighter than usual, restricting the tongue's movement. Some babies have no problems, while others find it harder to latch and feed.

Key takeaways

  • Not every tongue-tie needs treatment.
  • Feeding problems can include a poor latch, clicking sounds and sore nipples.
  • If needed, a quick procedure to divide the tissue can be done in young babies.

What you can do

  • Ask a midwife, health visitor or lactation consultant to watch a feed.
  • Discuss treatment options with a specialist if feeding is affected.

When to talk to your doctor

See your doctor if your baby has difficulty latching or feeding, is not gaining weight, or if breastfeeding remains painful.
