Ankyloglossia (Tongue-Tie)

What Are the Types of Ankyloglossia

Ankyloglossia is generally described by how much it limits tongue movement:

• Partial ankyloglossia — the frenulum restricts tongue movement to some degree, but the tongue is not completely fused to the floor of the mouth
• Total ankyloglossia — the tongue appears fused to the floor of the mouth, with very limited or no movement

Severity does not always predict how much of a functional problem a child will have. A child's ability to lift and move the tongue matters more than how the frenulum looks on examination.

What Causes Ankyloglossia

Ankyloglossia is a congenital condition — meaning it forms during development in the womb and is present at birth. It is not caused by anything a parent did or did not do during pregnancy. It can occur on its own or, less commonly, alongside other developmental conditions.

What Are the Signs and Symptoms of Ankyloglossia

Signs of ankyloglossia often show up differently depending on a child's age. In infants, the most common signs relate to feeding:

• Difficulty latching or staying latched during breastfeeding or bottle-feeding
• Slow or poor weight gain
• Clicking or smacking sounds while feeding
• Milk leaking from the mouth during feeds
• Reflux-like fussiness from swallowing air

In older children, signs are more often related to speech, tongue mobility, and gum health:

• Difficulty pronouncing sounds like "s," "z," "t," "d," "l," "sh," "ch," and "th," or rolling an "r"
• Trouble lifting the tongue to the roof of the mouth or sticking it past the lower lip
• Localized gum recession on the inner surface of the lower front teeth in some cases, where a tight frenal attachment pulls on the gum tissue

Not every child with a restricted frenulum experiences these problems, and mild cases are often not the primary cause of breastfeeding or speech difficulties — other factors are usually more common contributors and should be assessed alongside ankyloglossia rather than assumed to be caused by it.

What Happens If Ankyloglossia Is Left Untreated

Most children with a mild, non-restrictive frenulum need no treatment at all, and many grow and develop with no functional issues. Leading pediatric dental guidance is intentionally cautious here: appearance-based grading alone isn't considered a reliable way to diagnose or decide on treatment, and not every diagnosed case requires surgery.

Where ankyloglossia is genuinely restricting function, though, leaving it unaddressed can allow feeding difficulties in infancy, ongoing speech articulation challenges, or localized gum recession around the lower front teeth to continue rather than resolve on their own. This is why a proper functional assessment — not just a visual check — is the right first step.

How Is Ankyloglossia Treated

Treatment depends on the child's age, symptoms, and how much the frenulum is actually restricting function. Options include:

• Observation — for infants and children with no meaningful functional limitation, monitoring over time is often the appropriate approach, alongside feeding or lactation support where needed.
• Frenotomy (frenulotomy) — a simple clipping or incision of the frenulum. This is the most common procedure for infants with a clear feeding restriction.
• Frenectomy (frenulectomy) — the more complete removal of the frenulum, including its attachment. This is often the term used for frenectomy procedures performed in children, frequently using laser technology, which tends to mean less bleeding, no need for sutures, and a faster recovery.
• Frenuloplasty — a more involved surgical release, sometimes with repositioning of tissue and sutures, generally reserved for more complex cases.
• For infants with feeding difficulties, care is usually most effective as a team effort — involving a Specialist Pediatric Dentist, a lactation consultant, and sometimes a speech-language pathologist, rather than surgery alone. For older children where speech is the concern, a speech-language evaluation before any procedure helps confirm whether the frenulum is actually the cause.

Can Ankyloglossia Be Prevented

No. Ankyloglossia is a congenital condition that forms during fetal development, so there is no known way to prevent it. Early evaluation — ideally as part of routine infant and child dental checkups — is the best way to identify whether it is causing a functional problem worth addressing.
