Tongue Tie Symptoms in Infants: What Parents Need to Know

Bringing a new baby home is a time filled with joy, learning, and a host of new worries. One of the most immediate concerns for new parents is ensuring their infant is feeding well. When feeding is a struggle—for either baby or mother—it can be stressful and disheartening. While many factors can contribute to feeding difficulties, one common but often overlooked condition is ankyloglossia, more commonly known as a tongue tie.

Understanding tongue tie can help you identify potential issues early and seek the right support. It’s more than just a buzzword; it’s a real medical condition that can impact a baby’s ability to feed efficiently, gain weight, and even develop speech later on. This guide will provide clear, parent-focused information on what a tongue tie is, the signs to look for in your baby, how it affects development, and what treatment options are available.

What Is a Tongue Tie?

A tongue tie is a condition present at birth that restricts the tongue’s range of motion. Every baby is born with a band of tissue that connects the underside of the tongue to the floor of the mouth. This tissue is called the lingual frenulum. In some infants, this frenulum is unusually short, thick, or tight, which tethers the tongue and prevents it from moving freely.

Think of the tongue as a complex muscle responsible for much more than just tasting. For an infant, it needs to move in specific ways to create a proper seal around a nipple or bottle, extract milk, and swallow safely. When a tight frenulum restricts this movement, it can make effective feeding difficult or impossible.

There are different types of tongue ties, typically classified by where the frenulum attaches to the tongue. An “anterior” tie is visible near the tip of the tongue, sometimes creating a heart-shaped appearance when the baby cries or tries to stick their tongue out. A “posterior” tie is located further back, underneath the mucous membrane, making it less obvious to the naked eye. These can often be missed during a routine check but can cause significant feeding problems.

Signs and Symptoms of Tongue Tie in Babies

Identifying a tongue tie involves observing both the baby and the feeding parent. The challenges created by a restricted tongue can manifest in a variety of ways. If you notice several of the following signs, it may be time to consult a healthcare professional.

Symptoms in the Infant:

  • Difficulty Latching: The baby struggles to create a deep, sustainable latch on the breast or bottle. They may slip off frequently or have a shallow latch.
  • Clicking or Smacking Sounds: You might hear clicking noises while the baby feeds. This sound often indicates that the baby is losing suction because their tongue cannot maintain a proper seal.
  • Poor Weight Gain: If a baby cannot efficiently extract milk, they may struggle to gain weight at a healthy pace or even experience weight loss.
  • Prolonged or Frequent Feedings: The baby may seem to be feeding constantly or for very long stretches (e.g., more than 45 minutes) but still seem hungry and unsettled afterward. This is often due to inefficient milk transfer.
  • Gassiness and Fussiness: A poor latch can cause a baby to swallow excess air, leading to discomfort, gassiness, and colic-like symptoms.
  • Dribbling Milk: Milk may leak from the corners of the baby’s mouth during feedings because of an incomplete seal.
  • Visible Signs: You may notice a heart-shaped tongue tip when your baby cries, or they may be unable to stick their tongue out past their lower gum line.

Symptoms in the Breastfeeding Mother:

  • Nipple Pain and Damage: A shallow latch caused by a tongue tie is a primary cause of significant nipple pain, cracking, blistering, or bleeding for the nursing parent.
  • Compressed or Misshapen Nipples: After a feeding, the nipple may look flattened, creased, or blanched (white).
  • Low Milk Supply: Inefficient milk removal can signal the body to produce less milk, leading to a drop in supply over time.
  • Blocked Ducts or Mastitis: Poor milk drainage increases the risk of developing painful blocked ducts or an infection of the breast tissue known as mastitis.

How Tongue Tie Affects Feeding and Speech

The impact of an untreated tongue tie can extend beyond the newborn period. While feeding challenges are the most immediate concern, a restricted tongue can influence development in other areas as a child grows.

Impact on Feeding:

  • Breastfeeding: The tongue plays a crucial role in breastfeeding. It needs to extend and cup the nipple and areola, creating a vacuum to draw milk from the breast. A tongue tie prevents this, forcing the baby to use their gums to “chew” on the nipple, which is both painful for the mother and ineffective for the baby.
  • Bottle-Feeding: While some tongue-tied babies manage better with bottles, many still struggle. They may have trouble forming a seal around the bottle nipple, leading to milk leakage and swallowing air.
  • Introducing Solids: Later on, a restricted tongue can make it difficult for a child to manipulate solid food in their mouth. They may have trouble moving food from side to side for chewing, leading to gagging, choking, or picky eating habits focused on soft foods.

Impact on Speech Development:
As a child learns to talk, their tongue needs to move quickly and precisely to touch different parts of the mouth to form specific sounds. A significant tongue tie can interfere with the articulation of certain sounds, particularly those that require elevating the tongue tip, such as ‘t’, ‘d’, ‘l’, ‘n’, ‘s’, and ‘z’. While not every tongue-tied child will have speech problems, a restricted tongue is a physical limitation that can make clear speech more difficult to achieve. It can also contribute to challenges with oral hygiene, as the child may be unable to sweep their tongue across their teeth to clear food debris.

Treatment Options for Tongue Tie

If a tongue tie is causing problems, the most common treatment is a simple in-office procedure called a frenotomy (or frenectomy). This procedure involves releasing the tight frenulum to improve the tongue’s range of motion.

The Frenotomy Procedure:
A frenotomy is a quick and straightforward procedure that can be performed by a trained pediatrician, dentist, ENT (ear, nose, and throat doctor), or oral surgeon. For young infants, it is often done right in the office without the need for general anesthesia.

The provider will use sterile scissors or a laser to clip the frenulum. The procedure itself takes only a few seconds. There are very few nerve endings or blood vessels in the frenulum, so discomfort is minimal. Many babies sleep through it or are soothed immediately by nursing. There is typically very little bleeding—often just a drop or two.

After the Procedure:
The improvement in feeding can be immediate for some babies, while for others, it may take time. The baby essentially has to relearn how to use their newly freed tongue. Post-procedure care is critical and usually involves:

  • Stretches: Your provider will give you specific stretching exercises to perform on the area for several weeks. These are essential to prevent the frenulum from reattaching as it heals.
  • Bodywork and Therapy: It is often recommended to work with a professional, such as a lactation consultant (IBCLC), occupational therapist, or speech therapist, after the procedure. They can help the baby retrain the muscles used for sucking and address any compensatory habits they developed before the release.

The decision to treat a tongue tie is based on function, not just appearance. If the tie is not causing any feeding issues or other problems, no treatment may be necessary. However, when it interferes with a baby’s ability to thrive, a frenotomy can be a life-changing solution for the entire family.

Frequently Asked Questions (FAQ)

❓Can a tongue tie correct itself over time?

A significant tongue tie that impacts function will not correct itself. While the frenulum may stretch slightly as a child grows, a tight, restrictive band of tissue will remain unless it is surgically released. Waiting to treat a problematic tie can lead to prolonged feeding issues and potential speech challenges.

❓Who can diagnose a tongue tie?

A tongue tie should be diagnosed by a healthcare professional experienced in identifying and assessing oral restrictions. This includes International Board Certified Lactation Consultants (IBCLCs), pediatric dentists, pediatricians, or ENTs who specialize in this area. A functional assessment is key, not just a visual check.

❓Is a frenotomy procedure painful for my baby?

The frenotomy itself is extremely quick. In newborns, the frenulum has very few nerve endings, and the discomfort is minimal and brief. Most infants are calmed immediately by nursing or skin-to-skin contact. For older infants, a topical anesthetic may be used.

❓Will my child have speech problems if we don’t fix their tongue tie?

Not every child with a tongue tie will have speech problems, but it does increase the risk. A restricted tongue can make it difficult to produce sounds that require tongue tip elevation (like ‘l’, ‘t’, ‘d’). If feeding is not an issue, some parents choose to wait and monitor speech development, but early intervention is often recommended if the tie is significant.

❓What is the difference between a tongue tie and a lip tie?

A lip tie is a similar condition where the frenulum connecting the upper lip to the gum line is too tight. This can restrict the upper lip’s ability to flange out, which is necessary for a good seal during feeding. Lip ties and tongue ties often occur together and can both contribute to feeding difficulties.
