Lip ties (and their pictures on social media) drive me clinically nuts, because is so much confusion and misinformation about who actually has one. Too often medical professionals and lactation consultants say:

“All babies have lip ties”
“All babies have a band under there, there’s no such thing as a lip tie”
“That tissue will stretch with time/migrate up as they get older”
“They’ll eventually fall and break it on their own. No need to intervene”
“It doesn’t cause any problems, so just leave it alone”

On the flip side, some providers (and other random parents on social media forums) will say:

“See how the band of tissue is really low on the gums? That’s a lip tie”
“See how thick that band is? That lip is definitely tied”
“Lip ties are causing of all your nursing issues, cut it ASAP”
“Lip ties will cause all kinds of issues in the future, even if you don’t have symptoms now, better to cut it sooner rather than later”
“Where there’s a lip tie, there’s a tongue tie, your baby must be tied if they have any symptoms if a frenulum is visible”

I am the first to refer to the appropriate health care provider (ENT or pediatric dentist) when a true lip tie is not allowing proper function of the lips and is impacting the success of digestion or breastfeeding. But let’s understand a few things:

✏️According to a 1994 study by Flinck, who looked at >1000 babies, 77% of them had a frenulum that inserted “low” on to the gumline. A further 17% had a frenulum that inserted into the palate. So 94% of babies have a really low gum insertion – that is NOT the definition of a lip tie. Having a low set frenulum cannot be the only criteria used for release.

✏️There is currently no published criteria defining a normal frenulum vs a lip tie. That does not mean a lip shouldn’t be addressed when function is being impacted by anatomy. But that band between lip and gums is supposed to be there to some extent to help anchor your lips to your face for proper movement and facial development.

✏️Lip tie, when it is present, can certainly get in the way of a normal latch. A lip tie may cause increased air intake (contributing to reflux and gas), breast pain from the lips gripping too tightly to the breast, contribute to lip blisters muscle compensations, or not allow the baby to be able to maintain the latch through the whole feeding. While the lips are important for feeding, I’m more concerned about the tongue for obtaining a normal latch. Many compensations baby does to overcome a tongue tie may be mimicking issues seen with lip tie. Baby needs assessed for both.

✏️ It is rare for there to only be a lip tie. In the vast majority of cases, where there is a true lip tie there is also a tongue tie. The tongue is usually the reason for the symptoms as the tongue plays the major active role in breastfeeding. If the lip tie is released and symptoms persist, it is worth further evaluation of the tongue. I have had a few cases where a lip tie release only has resolved the breastfeeding issue, usually areola pain or popping on and off the breast from not being able to make a tight seal with the lips.

True diagnosis of lip tie is all about anatomy (what does it look like), physiology (what does it do), and symptoms (what is it causing). A lip tie will always impact function of the lip by restricting its expected movement. The upper lip should be soft and move to spread and pucker the lips without difficulty. The upper lip should play a passive role when breastfeeding, gently rounding to maintain the seal at the breast so milk doesn’t leak out and not gripping the breast.

An evaluation by an IBCLC should be mandatory before any baby is sent for oral surgery. Are the symptoms and behaviors at the breast being caused by poor position and latch? By tension in the body from birth trauma? Is tongue tie the actual culprit to the issues going on?

👄 The movement of the lip must be physically challenged to determine its full range of motion. If the lip is lifted up toward the nose, the center of the lip should move up toward the nose with the rest of the lip. If the center of the lip stays down against the gum line, it is most likely a tie. If no one physically flipped the lip up toward the nose, lip tie was not assessed.

👄 When you lift the lip, if the gums where the frenulum inserts turns white (blanches) OR the lip skin/frenulum turns white (blanches ) when you lift the lip up with reasonable amounts of pressure, the lip is tied.

👄 A notch in the bone of the gums where the frenulum attaches means the lip is tied. It indicates the tissue is so tight it’s now impacting the bone. This kind of lip tie needs immediately assessed and addressed as it most likely will impact dentition and dental hygiene.

👄 My baby has lip blisters. Does that mean they have a lip tie? Not necessarily. They may have a tongue tie and the lips are compensating for it. They may be constantly in a shallow latch at the breast or bottle and be using their lips to hang on. Lip blisters are a sign of shallow or dysfunctional latch and feeding should be observed to maximize latch.

👄 My baby always tucks their upper lip when nursing. Does that mean they have a lip tie? If the lip is still soft and can easily be flanges out, no, it’s not tied. Some babies like to tuck the upper lip or it gets accidentally tucked when latching and it’s not a problem. Tucking the upper lip can also happen when the tongue is tied- if the tongue can’t hold the seal (which is its job), then the lips have to. If the lips hold the seal, the lips have to be tucked in or milk will leak.

👄 The upper lip frenulum is one that can stretch and migrate up with time. As more teeth come in, the teeth may naturally help close the gap caused by some frenulum. If that is normal, why should it be released? An upper lip frenulum can migrate up over years, but if the restriction of the lip is affecting baby and mom NOW, then it should be treated NOW. Nipple pain and damage may have been normalized by the general public, but that does not mean it is normal. If you’re having symptoms associated with lip tie, have the lip and tongue assessed by someone who can properly evaluate and manage it.

A lot of emphasis is being put on lip ties right now, especially by well meaning parents on social media. Remember: you usually cannot tell if a lip is tied from a picture alone. A full, dynamic assessment is needed. If a health care provider looked at the lip without actually completing a full inner mouth assessment in the lips, cheeks and tongue, and observing a feeding, a full assessment wasn’t made. While a lip tie alone can get in the way of feeding and cause some pretty intense symptoms in some babies, the main focus should be on good position and deep latch with normal tongue mobility.

If you’re struggling with breastfeeding, seek out a qualified IBCLC or schedule your consultation with me ASAP to determine your next steps.
