Tongue-Tie (Ankyloglossia)

Tongue-tie is when a baby’s tongue can’t move as well as it should because a fold of tissue connects the bottom of their tongue to the floor of their mouth. This fold of tissue, called the lingual frenulum, is present in all children and usually harmless. But sometimes, a lingual frenulum that’s too tight or short can restrict the movement and function of a baby’s tongue. When this happens, healthcare providers diagnose a baby with ankyloglossia, more commonly known as tongue-tie.

Tongue-tie can sometimes pose challenges for breastfeeding (chestfeeding). Babies with tongue-tie may have trouble latching on or removing milk. This can prevent them from getting enough nutrition. Latching difficulties can also cause pain or discomfort for the breastfeeding parent, who may feel they need to stop breastfeeding.

If this sounds familiar, don’t give up. Often, lactation consultants can help you adjust your breastfeeding position or your baby’s latch to overcome these challenges. If these methods aren’t enough, your baby may need a safe and quick procedure called a frenotomy. This involves clipping the lingual frenulum so your baby’s tongue can move freely.

Your lactation consultant and pediatrician will work with you to find the best solution so both you and your baby can feel better.

How common is tongue-tie?

Anywhere from 1% to 11% of newborns have signs of ankyloglossia, according to the American Academy of Pediatrics. The condition appears to be more common in babies assigned male at birth (AMAB).
