Lip Tie vs Tongue Tie: The Difference and Why Treatment Plans Differ

A lip tie is a band of tissue that attaches your upper lip to your gum, while a tongue tie is a band of tissue under the tongue that restricts its movement. They are both tethered oral tissues, and they can occur alone or together, but they limit different movements and cause different problems. That is exactly why their treatment plans differ: a release that makes sense for a tongue tie may not be needed, or even helpful, for a lip tie, and vice versa.

As a trained orofacial myofunctional therapist in Las Vegas, I evaluate families across the valley who have been told their child has one or both of these ties. Some are told a lip tie needs surgery that turns out to be unnecessary. Others are told everything is fine when a tongue tie is quietly affecting feeding and speech. My goal is to help you understand the real difference so you can make a confident, informed decision for your child, or for yourself.

What exactly is a tongue tie?

A tongue tie, medically called ankyloglossia, is a short, tight band of tissue (the frenulum) that connects the underside of the tongue to the floor of the mouth. When it is too tight, the tongue cannot move the way it should. It may not lift to the roof of the mouth, extend past the lips, move side to side, or reach where it needs to for feeding, swallowing, and speech.

Tongue ties come in different forms. An anterior tongue tie is visible near the tip of the tongue. A posterior tongue tie sits further back and is harder to see without a trained eye, but it can be just as restrictive. The effects show up in breastfeeding, in the transition to solid foods, in speech development, and in the resting posture of the tongue. Because the tongue does so much of the work in the mouth, a restricted tongue can have a wide ripple effect. You can read more about the basics of tongue tie here if you are just getting started.

What exactly is a lip tie?

A lip tie is a band of tissue that connects the inside of the upper lip to the gum above the two front teeth. Everyone has some attachment there, but when it is unusually thick, tight, or extends far down the gum, it is called a lip tie. A restricted upper lip may not be able to flare upward and outward, which is the movement your baby needs to form a tight seal while breastfeeding or bottle feeding.

A lip tie is often most noticeable in feeding, because a baby needs a good upper lip seal to keep milk in the mouth. It can also be linked to early childhood cavities, because a tight upper lip may make it harder to clean the upper front teeth. And in older children, a strong attachment can be one factor behind a gap between the two front teeth, although this is not always a problem that needs treatment.

What are the key differences between a lip tie and a tongue tie?

The simplest way to think about it is location and function. A tongue tie is under the tongue and affects the tongue's ability to move. A lip tie is at the upper lip and affects the lip's ability to move and seal. Those differences lead to different symptoms:

• Feeding. A tongue tie interferes with how the tongue moves milk and creates suction. A lip tie interferes with the seal that keeps milk in the mouth. Both can make feeding difficult, but in different ways, which is why a feeding assessment has to look at both.
• Speech. Tongue tie more commonly affects speech sounds that need tongue movement, like certain consonants. Lip tie has a much smaller role in speech.
• Oral hygiene and teeth. Lip tie can contribute to decay on the upper front teeth and to a gap between them. Tongue tie is more connected to tongue posture and airway and swallowing patterns.
• Visibility. Anterior tongue ties and lip ties are often visible, while posterior tongue ties are not. That is why a professional evaluation matters.

The overlap is real, and many babies have both. That is one reason the terms get tangled up. But because they restrict different things, the evaluation and the treatment plan should treat each one on its own merits.

Can a child have both a lip tie and a tongue tie?

Yes, and it is common. When a baby has both, the feeding challenges can be more significant because two separate restrictions are working against them. The tongue cannot move well and the lip cannot seal, which together make an efficient latch very difficult.

When both ties are present, a thorough myofunctional evaluation looks at the whole picture before any treatment is recommended. We do not just look at the most obvious tie. We watch how the tongue moves, how the lip moves, how the baby feeds, and how the mouth functions overall. The oral-systemic health connection is well established: how these tissues function from infancy shapes feeding, breathing, and development for years. If you are noticing feeding or breathing concerns, a myofunctional therapy evaluation is a sensible place to start.

Why do lip tie and tongue tie treatment plans differ?

Because they restrict different movements, the decision to release a tie is driven by function, not by appearance. A tongue tie is more often released when it is restricting feeding, speech, or airway-related function. A lip tie is often treated more conservatively, because many lip ties never cause real problems. Many providers, including me, take a more cautious approach to lip tie release unless there is clear evidence it is causing a functional problem.

Release is also not the only option, or even the first one. Orofacial myofunctional therapy can improve tongue and lip function before any surgery is considered. For a tongue tie, pre-release therapy can strengthen the tongue and improve mobility within the restriction. For a lip tie, therapy can help the lip move more fully and improve the seal. In some cases, function improves enough that a release becomes unnecessary.

When a release is recommended, therapy continues afterward to prevent reattachment and to retrain the muscles into their new, fuller range of motion. Skipping therapy after a release can lead to reattachment and disappointing results, so the follow-up is a real part of the treatment plan, whether we are talking about a lip tie or a tongue tie.

Does every lip tie need to be released?

No, and this is one of the most important things I tell parents. Many lip ties never cause a problem. A tight upper lip that still lets a baby form a good seal, eat well, and grow normally may not need any intervention at all. Treatment should be based on how the mouth is actually functioning, not on how the tissue looks.

That is why a qualified myofunctional therapist is the right first stop. We can tell you whether the lip tie is restricting function, whether a tongue tie is also present, and whether therapy, release, or a watch-and-see approach makes the most sense. In Las Vegas, Thrive Professional Solutions offers comprehensive evaluations for infants, children, and adults, and we partner with pediatric dentists and ENTs across the valley to coordinate care when a release is warranted.

When should I see a professional about a possible lip or tongue tie?

Consider an evaluation if you notice feeding difficulties, pain while breastfeeding, poor weight gain, clicking while feeding, a heart-shaped tongue tip, difficulty extending the tongue, or a visible tight band at the upper lip that seems to limit its movement. Speech delays, picky eating, gagging on textured foods, and mouth breathing can also be related to restricted oral tissues.

It is worth saying plainly: not every provider is trained to identify these ties, especially posterior ones. If you have been told everything is fine but the struggles continue, a second opinion from someone who specializes in tethered oral tissues is reasonable. A lactation consultant, pediatrician, dentist, or ENT who understands myofunctional therapy can all be part of your team.

If you live in or near Las Vegas, I would be glad to help you sort it out. Schedule a free consultation to talk about your child's feeding, your pain, or your own symptoms, and we will look at the whole picture together.

Understanding the difference between a lip tie and a tongue tie is the first step, but you do not have to figure it out alone. A proper evaluation gives you clarity, and clarity lets you make the decision that is truly right for your child and your family.
