What Is Tongue-Tie?
The lingual frenulum is a thin band of tissue that connects the underside of the tongue to the floor of the mouth. Everyone has a frenulum, but in babies with tongue-tie, this tissue is unusually short, thick, or tight. The restricted frenulum limits how far the tongue can move up, forward, and side to side.
Tongue-tie exists on a spectrum. Some babies have a mild restriction that causes no problems at all. Others have a severe restriction that significantly affects their ability to feed. The clinical significance of a tongue-tie depends not just on how the frenulum looks, but on how well the baby can use their tongue to latch, suck, and swallow.
Types of Tongue-Tie
Tongue-ties are sometimes classified by where the frenulum attaches to the tongue.
- Anterior tongue-tie: The frenulum attaches at or near the tip of the tongue, creating the classic heart-shaped appearance when the baby tries to lift or extend the tongue. This type is usually easy to see.
- Posterior tongue-tie: The frenulum attaches further back on the underside of the tongue. Posterior ties can be harder to identify visually because the restriction is less obvious, but they can still limit tongue function.
- Submucosal tongue-tie: The restrictive tissue is hidden beneath the mucous membrane of the mouth floor. This type is the most difficult to diagnose because it may not be visible at all without a hands-on assessment.
How Tongue-Tie Affects Babies
Tongue-tie is a congenital condition, meaning babies are born with it. During fetal development, the frenulum normally thins and recedes. In babies with ankyloglossia, this process does not complete fully. The exact cause is not well understood, though there appears to be a genetic component, as tongue-tie tends to run in families.
Impact on Breastfeeding
Breastfeeding requires the baby to extend the tongue over the lower gum, cup it around the breast, and create a seal for effective suction. A restricted tongue cannot perform these movements fully, which often leads to a shallow or painful latch.
Signs of tongue-tie during breastfeeding include:
- Difficulty latching or frequent loss of latch during feeding
- Clicking or smacking sounds while nursing
- Prolonged feeding sessions with the baby seeming unsatisfied afterward
- Poor weight gain in the baby
- Painful, cracked, or blistered nipples in the nursing parent
- Recurrent mastitis or clogged milk ducts
- Low milk supply (often secondary to ineffective milk removal by the baby)
Impact on Bottle Feeding
Tongue-tie can also affect bottle-fed babies, though the impact is often less pronounced. Babies with tongue-tie may have trouble forming a seal around the bottle nipple, take in excessive air while feeding (leading to gas and fussiness), or feed very slowly. Some babies compensate by using their jaw muscles more, which can lead to fatigue and shorter feeds.
Potential Effects on Speech and Development
Not all children with untreated tongue-tie develop speech problems, but some may have difficulty with sounds that require the tongue to reach the roof of the mouth, such as "t," "d," "l," "n," and "r." Other potential effects include difficulty licking the lips, eating certain foods like ice cream cones, or playing wind instruments. These effects vary widely, and many children with mild tongue-tie develop normal speech without intervention.
Diagnosis and Treatment
Tongue-tie is diagnosed through a physical examination of the baby's mouth. There is no blood test or imaging study for this condition. The key question is whether the anatomical restriction is causing a functional problem for the baby.
How Tongue-Tie Is Diagnosed
A pediatric dentist, pediatrician, ENT specialist, or lactation consultant can assess for tongue-tie. The examiner lifts the baby's tongue to check the length, thickness, and elasticity of the frenulum and observes how far the tongue can extend, elevate, and move side to side.
Several scoring tools exist to standardize the assessment, including the Hazelbaker Assessment Tool for Lingual Frenulum Function (HATLFF) and the Bristol Tongue Assessment Tool. These tools evaluate both the appearance of the frenulum and the tongue's functional movement. A functional assessment that includes observing a breastfeed is often the most valuable diagnostic step.
Frenotomy (Simple Tongue-Tie Release)
A frenotomy is a quick procedure in which the frenulum is cut with sterile scissors or a laser. In newborns and young infants, the frenulum has very few nerve endings and minimal blood supply, so the procedure causes only brief discomfort. Many practitioners perform frenotomy without anesthesia in very young babies, though some apply a topical numbing agent.
The procedure takes only a few seconds. Bleeding is minimal, usually just a few drops. Most babies can breastfeed immediately after the procedure, and many parents notice an improvement in latch within the first few feeds.
Frenectomy (Surgical Removal)
A frenectomy is a more involved procedure that removes the frenulum tissue rather than simply cutting it. This may be recommended for thicker frenulums or in older infants and children. A frenectomy is typically performed under local anesthesia and may use a scalpel, electrocautery, or laser.
Laser frenectomy has become increasingly popular because it causes less bleeding and may result in less postoperative discomfort. However, there is currently limited high-quality evidence comparing laser outcomes to scissor frenotomy in terms of long-term results.
Recovery and Aftercare
Recovery after a frenotomy or frenectomy is generally quick. Most babies return to normal feeding within hours to days.
Post-Procedure Care
After a frenotomy, the wound under the tongue forms a white or yellowish patch. This is normal healing tissue, not an infection. The area typically heals within 1 to 2 weeks.
Many providers recommend wound stretching exercises for 2 to 4 weeks after the procedure. These involve gently lifting the tongue and sweeping a clean finger under it several times a day to prevent the frenulum from reattaching. Your provider will demonstrate the technique and explain the recommended frequency.
Feeding After the Release
Some babies latch better and feed more effectively right away. Others need time to relearn feeding patterns, especially if they developed compensatory habits before the release. Working with a lactation consultant before and after the procedure can help both parent and baby adjust.
It is important to have realistic expectations. A tongue-tie release may not solve all breastfeeding difficulties. Other factors, including milk supply, breast anatomy, and the baby's oral motor skills, also play a role. A multidisciplinary approach involving the pediatric dentist, pediatrician, and lactation consultant typically produces the best outcomes.
Possible Complications
Complications from frenotomy and frenectomy are rare. The most common issues include minor bleeding (usually resolves with gentle pressure), reattachment of the frenulum (may require a second release), and temporary fussiness. Infection is uncommon. If you notice excessive bleeding, fever, or refusal to feed for more than 8 hours after the procedure, contact your provider.
Tongue-Tie Treatment Costs
The cost of tongue-tie evaluation and treatment depends on the type of provider, the procedure used, and whether additional services like lactation support are included. Costs vary by location and provider.
Typical Cost Ranges
A frenotomy (scissor release) typically costs between $150 and $500. A laser frenectomy usually costs between $400 and $1,200. These costs may include the consultation and follow-up visit, or those may be billed separately. A lactation consultation, which is often recommended alongside the procedure, typically costs $100 to $300 per session.
Insurance and Medicaid Coverage
Coverage for tongue-tie procedures varies significantly by insurance plan. Some medical and dental plans cover frenotomy or frenectomy when it is deemed medically necessary (for example, when it is causing documented feeding problems and weight gain issues). Other plans consider it elective. Medicaid coverage also varies by state.
If a pediatric dentist performs the procedure, it may be billed under dental insurance. If an ENT or pediatrician performs it, it is typically billed under medical insurance. Ask your provider about billing codes and check with your insurance company before the procedure to understand your out-of-pocket costs.
When to Seek Help for Tongue-Tie
If your baby is struggling to breastfeed or bottle feed and you suspect tongue-tie, start by consulting a lactation consultant who can assess feeding function and refer you to a provider who evaluates tongue-tie if appropriate.
Seek evaluation from a pediatric dentist, pediatrician, or ENT specialist if your baby has a poor or painful latch, is not gaining weight appropriately, or if a heart-shaped tongue tip is visible when the baby cries. Early evaluation is important because the longer feeding problems persist, the greater the impact on milk supply, infant nutrition, and parental well-being.
When Treatment May Not Be Necessary
Not every tongue-tie needs to be released. If a baby has an anatomical tongue-tie but is feeding well, gaining weight normally, and the nursing parent is comfortable, observation may be the best approach. The frenulum can sometimes stretch or thin out on its own as the child grows. A careful functional assessment, not just the appearance of the frenulum, should guide the decision.
Find a Specialist for Tongue-Tie Evaluation
Several types of providers can evaluate and treat tongue-tie in babies. A pediatric dentist with experience in frenectomy procedures is one excellent option. Other qualified providers include pediatric ENTs and some pediatricians with training in tongue-tie assessment.
When choosing a provider, ask about their experience with tongue-tie diagnosis, the number of procedures they have performed, whether they use a functional assessment (not just visual), and whether they coordinate care with a lactation consultant.
