Overview

What Is Tongue Tie?

Tongue tie, also called ankyloglossia, occurs when the band of tissue under the tongue, called the lingual frenulum, restricts tongue movement. Some babies have a visible frenulum but no feeding or other problems. Others may have difficulty latching or transferring milk, while older children and adults may have concerns with oral function. This condition is also described as a tied tongue in newborns.

Symptoms

Signs and Symptoms of Tongue Tie

  • Difficulty latching during breastfeeding or bottle-feeding.
  • Feeds that take unusually long to complete.
  • Clicking sounds during feeding.
  • Poor milk transfer during feeding.
  • Nipple pain during breastfeeding.
  • Poor weight gain in an infant.
  • Difficulty lifting the tongue toward the roof of the mouth.
  • Difficulty sticking out the tongue.
  • Speech concerns in an older child.
  • Difficulty clearing food or maintaining oral hygiene.

IMPORTANT

Consider other causes

Feeding and speech concerns can have many causes and should not automatically be attributed to tongue tie. A clinician or feeding specialist can assess the full situation and recommend appropriate support.

Causes

What Causes Tongue Tie?

Tongue tie is present from birth when the lingual frenulum is unusually short, thick, tight, or attached farther forward than usual. This can limit how far the tongue lifts, extends, or moves from side to side. The exact cause is often unclear, although inherited factors may play a role. A posterior tongue tie may be less obvious because the restriction is farther back under the tongue.

Risk Factors

Risk Factors for Tongue Tie

  • A family history of tongue tie.
  • Being born with an unusually short, tight, thick, or forward-attached frenulum.

There is no established lifestyle change that reliably prevents tongue tie. Many babies with no identifiable risk factor may have it.

Complications

Possible Complications of Tongue Tie

  • Ineffective milk transfer during feeding.
  • Inadequate weight gain in an infant.
  • Ongoing nipple pain during breastfeeding.
  • Difficulty cleaning the teeth or maintaining oral hygiene.
  • Frustration related to feeding or other oral functions.

WHEN TO ACT

Do not delay infant care

Poor feeding, signs of dehydration, or inadequate weight gain in a newborn require prompt clinical assessment. Do not wait for tongue tie to resolve before seeking help.

Diagnosis

How Is Tongue Tie Diagnosed?

Diagnosis is usually based on the medical history, inspection of the frenulum, and assessment of tongue movement. A clinician may also observe feeding or another functional concern to determine whether restricted movement is causing problems. There is no single routine imaging test used to diagnose tongue tie.

What the Assessment May Include

  • Infant feeding history.
  • Observation of latch and milk transfer.
  • Assessment of tongue elevation and extension.
  • Examination of the mouth and tongue frenulum.
  • Review of the infant’s weight pattern.
  • Evaluation of speech or dental concerns when relevant.

Treatment & Management

Tongue Tie Treatment and Management

Treatment depends on how much the condition affects function. Observation, breastfeeding support, feeding therapy, and follow-up may be appropriate when symptoms are mild, improving, or not clearly linked to the frenulum. A clinician can help monitor feeding, growth, and other concerns before deciding whether a procedure is needed.

Tongue Tie Release

A frenotomy releases the restrictive frenulum, while a frenuloplasty releases and revises the tissue, sometimes with closure of the wound. These procedures may be performed by a suitably trained clinician, and the approach can vary with the person’s age, anatomy, and needs. Infants may have brief discomfort, while older children and adults may need local or general anesthesia depending on the procedure. Healing, aftercare, possible bleeding or infection, and the expected benefits and risks should be discussed with a qualified clinician.

BEFORE TREATMENT

Base treatment on function

A visible frenulum does not automatically need release, and evidence for some proposed benefits is limited. Avoid unlicensed procedures and do not choose tongue tie surgery solely from photographs; seek an in-person assessment.

Outlook and Prognosis

Outlook for Tongue Tie

Many people with tongue tie have no lasting problems. Others improve with feeding support or a tongue tie release when restricted movement is causing a documented functional issue. Improvement depends on the original problem and may need follow-up rather than being judged by the appearance of the frenulum alone.

  • A feeding review can show whether latch and milk transfer are improving.
  • The wound should be monitored for normal healing after a release procedure.
  • Symptoms should be tracked rather than assuming they will improve immediately.
  • Reassessment may be needed if the original difficulty continues.

When Should You See a Doctor

When Should You See a Doctor for Tongue Tie?

  • A newborn cannot latch or feed effectively.
  • An infant shows signs of dehydration.
  • An infant is not gaining weight as expected.
  • Breastfeeding pain persists despite feeding support.
  • Speech or oral-function concerns continue.
  • You have questions about a possible release procedure.
