Signs Your Newborn May Have a Lip or Tongue Tie: What Parents Should Know Early

If breastfeeding hurts, your baby seems to nurse constantly without gaining weight, or feeding sessions feel more like a battle than bonding time, you may already suspect something isn't quite right. Often, the answer is a lip tie or tongue tie, a piece of tissue that's a little too tight, a little too thick, or attached in a spot that restricts movement.

As a pediatric dentist trained in airway and tongue tie evaluation, I see families in Frederick every week who spend weeks (sometimes months) being told "it's probably nothing" before someone finally looks closely at the mouth. Early recognition matters, not just for feeding, but for long-term airway, speech, and oral development. Here's what to watch for.

What Is a Lip or Tongue Tie?

Every baby is born with small bands of tissue (called frenula) connecting the lip to the gums and the tongue to the floor of the mouth. In most babies, these bands are thin and flexible enough to allow full range of motion. In babies with a tie, that tissue is tighter, thicker, or positioned in a way that restricts how far the tongue or lip can move.

• Tongue tie (ankyloglossia): restricts the tongue's ability to lift, extend, or move side to side
• Lip tie: restricts the upper lip's ability to flange outward, which can affect the seal needed for efficient feeding

Neither is a reflection of anything a parent did during pregnancy. It's simply how the tissue developed.

Early Feeding Signs Parents Notice First

Feeding difficulties are usually the first clue, especially for breastfeeding parents. Common signs include:

• Painful latch that doesn't improve with repositioning or lactation support
• Clicking sounds while nursing (a sign the seal keeps breaking)
• Milk leaking from the corners of the mouth during feeds
• Long feeding sessions (45+ minutes) with the baby still seeming hungry afterward
• Falling asleep at the breast from exhaustion rather than fullness
• Poor weight gain or slow return to birth weight
• Reflux-like symptoms from swallowing excess air during an inefficient latch
• Gassiness or colic-like fussiness, especially after feeds 

Bottle-fed babies can show ties too. Look for milk dribbling from the sides of the mouth, a lot of air intake (visible bubbles in the bottle), or a baby who seems to gum or chew the nipple rather than draw milk with a smooth suction.

Signs That Show Up in the Mouth Itself

Beyond feeding, there are physical signs you can sometimes spot yourself:

• A heart-shaped or notched tongue tip when your baby cries or tries to lift the tongue
• The tongue can't lift to touch the roof of the mouth, even with the mouth wide open
• The upper lip doesn't flange out well and tends to curl inward during feeding
• A visible tight band of tissue under the tongue or behind the upper lip
• A gap between the upper front teeth later on, once teeth erupt, from lip tension

Not every baby with these features needs treatment. The key question is always function, not appearance. A tongue that looks tied but moves freely is different from one that looks fine but can't achieve full range of motion.

Why Early Evaluation Matters for More Than Just Feeding

This is where airway-focused pediatric dentistry differs from a quick visual check. The tongue plays a central role in shaping the palate, guiding jaw growth, and supporting a healthy airway throughout childhood. A restricted tongue that can't rest properly against the roof of the mouth can contribute to:

• Narrow, high-arched palate development
• Mouth breathing habits
• Future crowding or orthodontic needs
• Speech sound difficulties as your child grows (particularly with sounds like t, d, l, n, r)
• Sleep-disordered breathing patterns later in childhood

This is why we evaluate ties as part of a full airway assessment rather than in isolation. The goal isn't just "can baby feed today," but "how will this tissue restriction affect growth and development over time."

What an Evaluation With Us Looks Like

At Tiny Trips Pediatric Dentistry in Frederick, tongue and lip tie evaluations include:

1. A functional assessment — watching how the tongue and lips actually move, not just how they look
2. A feeding history discussion, often alongside your pediatrician, lactation consultant, or IBCLC
3. An airway-informed exam, since ties rarely exist in isolation from broader oral and facial development
4. A conversation about options, since not every tie needs a release — many resolve or compensate with therapy alone

When a release is recommended, we use a CO2 laser frenectomy (LightScalpel), which is precise, minimizes bleeding, and typically allows babies to nurse comfortably again within the same day.

The Overtreatment Question Parents Are Right to Ask

You may have read conflicting opinions online about whether tongue tie release is over-diagnosed. It's a fair concern, and a good pediatric dental provider should welcome the question rather than dismiss it. The honest answer: not every tight-looking piece of tissue needs to be cut. A thorough evaluation looks at function first, involves your feeding support team, and only recommends a frenectomy when the restriction is clearly impacting feeding, comfort, or development. If a provider recommends a release without ever watching your baby feed or examining tongue mobility, that's worth a second opinion.

When to Reach Out

If you're dealing with painful nursing, slow weight gain, or a baby who seems to struggle at every feed, don't wait it out hoping it resolves on its own. Early evaluation, ideally in the first few weeks, gives you and your baby the most options and the least frustration.
