Tongue-Ties and Lip-Ties in Babies: What Parents Should Know

If you have spent any time in new-parent groups, you have probably heard "tongue-tie" mentioned as the explanation for everything from a painful latch to a fussy feeder. Some of those concerns are real and treatable. But the diagnosis has also become more common than the evidence fully supports — so a calm, balanced look helps.

What a tongue-tie actually is

A tongue-tie — clinically, ankyloglossia — is a tight or short band of tissue (the lingual frenulum) under the tongue that can limit how freely the tongue moves. A lip-tie refers to a tight band connecting the upper lip to the gums. The American Academy of Pediatrics notes that an estimated 4% to 10% of newborns have some degree of tongue-tie.

Importantly, having a tie is not the same as having a problem. Many babies with a visible frenulum feed, grow, and later speak perfectly well.

How it can affect feeding

The main reason a tie gets attention in infancy is feeding. According to the AAP, the considerations that most matter when evaluating a possible tongue-tie are an ineffective latch and poor weight gain. Signs that sometimes prompt an assessment include:

• Persistent pain or nipple damage during breastfeeding
• A baby who struggles to stay latched or feeds very inefficiently
• Poor weight gain despite frequent feeding

A measured approach to treatment

This is where the AAP urges caution. Their guidance is to first consider non-surgical options — such as lactation support to improve positioning and latch — rather than moving straight to a procedure. A frenotomy (a small release of the frenulum, often a quick scissor clip) is generally reserved for cases with significant functional impairment where non-surgical help has not worked.

The AAP also notes that research on frenotomy is limited: reviews suggest a short-term reduction in nipple pain for nursing mothers, but the effect on the baby's feeding is inconsistent. A growing number of babies are being diagnosed and treated, and many experts believe the procedure is being overused.

What about speech?

Parents often worry a tie will cause a lifelong speech problem. The evidence here is genuinely limited, and a tie is far from the most common cause of speech delays. If you have concerns about speech as your child grows, the better first step is usually an evaluation by your pediatrician or a speech-language pathologist, rather than assuming a frenulum is the cause.

When an assessment makes sense

You do not need to chase a diagnosis, but it is reasonable to seek a professional assessment if:

• Breastfeeding is consistently painful despite good support
• Your baby has poor weight gain or clearly struggles to feed
• You have specific, ongoing concerns as your child develops

A thoughtful evaluation — ideally one that includes feeding support, not just a look at the tissue — helps you make a decision based on function, not appearance alone.
