Ankyloglossia, commonly known as tongue tie, is a congenital condition where the thin band of tissue beneath the tongue, called the lingual frenulum, is unusually short, thick, or tight. This restriction limits the tongue’s range of motion, crucial for effective feeding, especially breastfeeding. While some babies experience no difficulties, others may have problems with milk transfer and oral development. Recognizing the typical signs helps parents understand if this anatomical difference is affecting their baby’s ability to feed well.
Visible Anatomical Indicators
The primary physical sign of tongue tie involves observing the appearance and movement of the tongue itself. The condition varies in severity, but the restrictive frenulum is often visible and can be felt. A frenulum that is thick, short, or extends too close to the tip of the tongue indicates limited mobility.
When the baby cries, the tip of the tongue may appear notched, flattened, or distinctly heart-shaped because the frenulum pulls the center down. The baby may struggle to lift the tongue to touch the upper gum or the roof of the mouth. Limited lateral movement may also be observed, sometimes resulting in a V-shaped appearance when the tongue is extended.
Feeding Difficulties Experienced by the Infant
Beyond the visual signs, the most common indication of a functional restriction is difficulty during feeding. An infant must be able to extend the tongue over the lower gum ridge and use a wave-like motion to draw milk. With a tongue tie, the inability to extend the tongue often results in a shallow latch, where the baby latches only onto the nipple rather than the areola.
This poor latch frequently breaks the vacuum, resulting in a characteristic clicking or smacking sound during the feed. The baby may compensate by chewing or gumming the nipple, which is an inefficient way to remove milk. Consequently, feeding sessions may be prolonged, or the baby may become fussy, pulling off the breast or bottle frequently due to frustration and fatigue.
The baby’s inability to effectively extract milk can lead to excessive air intake, manifesting as gas, reflux symptoms, or fussiness after feeding. Poor weight gain or failure to thrive is a significant concern stemming from ineffective milk transfer, as the baby expends energy without receiving adequate nutrition. This consequence often prompts medical evaluation.
Maternal Symptoms During Nursing
A baby’s tongue tie often affects the nursing parent, with symptoms resulting from the baby’s attempt to compensate for poor oral function. Nipple pain or trauma is a frequently reported sign, as the shallow latch and compensatory chewing motion cause friction and pressure. This can lead to cracked, blistered, or bleeding nipples.
The mother’s nipple may appear misshapen after a feeding, often described as flattened, beveled, or having a “lipstick” shape. This indicates the nipple was compressed rather than properly drawn into the baby’s mouth. Inadequate drainage due to the baby’s weak or inefficient suck can cause blocked milk ducts, engorgement, or recurrent episodes of mastitis.
Over time, the lack of proper stimulation and milk removal can signal the body to reduce production, leading to a low milk supply. While other issues can cause these maternal symptoms, their presence alongside infant feeding difficulties should prompt an investigation into a possible tongue tie.
Seeking Professional Diagnosis
If parents notice a combination of anatomical, infant feeding, and maternal symptoms, the next step is to consult with a healthcare professional. Self-identification is merely a suspicion; a definitive diagnosis requires a clinical assessment. Specialists often involved include pediatricians, ear, nose, and throat (ENT) physicians, or an International Board Certified Lactation Consultant (IBCLC).
A proper diagnosis goes beyond a simple visual check of the frenulum; it focuses on a functional assessment of the tongue’s mobility and its impact on feeding. Professionals may use specialized tools like the Hazelbaker Assessment Tool for Lingual Frenulum Function (HATLFF) or the Bristol Tongue Assessment Tool (BTAT). These tools assign scores based on both the anatomy and the observable feeding function, providing an objective measure of the restriction.
The assessment typically includes observing the baby during a feeding session to evaluate the latch, suck pattern, and milk transfer effectiveness. The correlation between the restricted anatomy and the resulting functional feeding problems confirms a diagnosis of symptomatic ankyloglossia. The professional will then discuss the findings and potential management pathways focused on improving feeding function.
