A lingual frenectomy is a minor surgical procedure that releases the small fold of tissue connecting the underside of your tongue to the floor of your mouth. This tissue, called the lingual frenulum, is normally thin and flexible enough to allow full tongue movement. When it’s too short, thick, or tight, it restricts the tongue’s range of motion, a condition known as ankyloglossia or tongue-tie. A lingual frenectomy cuts or removes that tissue to restore normal function.
Why the Procedure Is Done
The most common reason for a lingual frenectomy is breastfeeding difficulty in newborns. When a baby’s tongue can’t extend past the gums, it struggles to latch properly, which leads to poor milk transfer and often severe nipple pain for the nursing parent. That pain can be intense enough that some parents stop breastfeeding entirely. In these cases, releasing the frenulum can reduce pain and improve latch, though outcomes vary. Healthy nursing also depends on how well the middle of the tongue moves, not just the tip, which is why the procedure helps some babies more than others.
In older children, a tight frenulum can interfere with speech development, particularly sounds that require the tongue to reach the roof of the mouth or press behind the teeth. Sounds like “L,” “TH,” and “R” are commonly affected. Some children also have difficulty licking their lips, eating certain foods, or playing wind instruments. Adults occasionally seek the procedure for similar functional limitations or because a tight frenulum contributes to dental concerns, such as pulling on the tissue behind the lower front teeth.
The American Academy of Pediatrics encourages doctors to try nonsurgical approaches first, especially for breastfeeding problems. These can include lactation support, positional adjustments, and feeding therapy. The AAP recommends reserving frenectomy for cases where significant functional impairment persists after those options have been tried.
How Tongue-Tie Is Classified
Not all tongue-ties look or behave the same way. Providers sometimes use a classification system that grades the tie based on where the frenulum attaches. A Class IV tie anchors close to the tongue tip, creating the most visible restriction. A Class III tie attaches slightly further back but still in front of the salivary ducts under the tongue. Class II and Class I ties attach progressively closer to the base of the tongue, making them harder to spot on a visual exam. These posterior ties can still restrict movement even though they aren’t obvious at first glance.
There’s no single diagnostic test that definitively determines whether a frenectomy is needed. Providers evaluate tongue mobility, the appearance of the frenulum, and most importantly, whether it’s causing a real functional problem like feeding difficulty or speech limitation.
What Happens During the Procedure
For newborns, a lingual frenectomy is remarkably quick. A trained provider, often a pediatrician, ENT physician, or breastfeeding medicine specialist, snips the frenulum with sterile scissors. The tissue in very young babies is thin and has few blood vessels or nerve endings, so anesthesia is typically unnecessary. Bleeding is minimal, usually just a drop or two, and many babies can breastfeed immediately afterward.
For older children and adults, the tissue is thicker and may have more blood supply, so the procedure requires local anesthesia. In these cases, providers may use a scalpel or a surgical laser. A more involved version called a frenuloplasty may be performed, which involves reshaping the tissue and closing the site with dissolvable stitches.
Laser vs. Traditional Scalpel
Laser frenectomy has become increasingly popular, particularly with families seeking the procedure for infants and young children. Compared to a scalpel, lasers cause less bleeding because they seal blood vessels as they cut. They also tend to result in less post-operative discomfort during speaking and chewing, and the procedure itself is about four minutes shorter on average. Wound healing is generally faster with less scar tissue formation, and stitches are usually not needed. Both approaches are effective, and the choice often depends on the provider’s training and the equipment available in their practice.
Recovery and Healing Timeline
After the release, you’ll notice a diamond-shaped wound under the tongue. This is normal and expected. Within one to four days, the body starts laying down new connective tissue at the wound site, forming a flexible yellowish or white layer that looks like a scab. This is a sign of healthy healing, not infection.
Around day five, the wound typically appears as a distinct yellow or white diamond shape. By day seven, it begins to shrink, and the coating becomes thinner. Over the second week, the diamond continues getting smaller and the coating disappears. By week three, the wound may no longer be visible at all. Full healing, including tissue remodeling and the formation of a new, more flexible frenulum, takes roughly five weeks. At that point, any remaining scar tissue is usually thin and translucent, and feeding or speech symptoms have typically resolved.
Post-Procedure Exercises
For infants, many providers recommend gentle tongue stretching exercises after the release. The goal is to prevent the wound edges from fusing back together as they heal, which could recreate the restriction. A typical routine involves performing each stretch a couple of times, two to three times per day, continuing for a few weeks or until feeding has clearly improved.
It’s worth noting that the AAP has recommended against aggressive wound stretching where parents repeatedly open the healing site to prevent reattachment. The exercises should be gentle. Your provider should demonstrate exactly what to do and how much pressure is appropriate, since overly forceful stretching can cause unnecessary pain and may not improve outcomes.
Risks and Complications
Complications from a lingual frenectomy are rare. The main risks include minor bleeding, infection, and damage to the tongue or salivary glands (which sit just beneath the frenulum on the floor of the mouth). Scarring can occur, particularly with a frenuloplasty, which involves more tissue removal. There’s also a chance the frenulum reattaches to the base of the tongue during healing, which is one reason stretching exercises are recommended. When a frenuloplasty is performed under general anesthesia, reactions to anesthesia are an additional but uncommon risk.
Effects on Jaw and Tooth Alignment
A tight lingual frenulum can influence how the jaw and teeth develop, though the relationship is complex. The tongue normally rests against the roof of the mouth and exerts outward pressure that helps shape the upper jaw as a child grows. When tongue movement is restricted, that pressure is reduced, which may affect the width and shape of the dental arch over time. Some research has found a link between shorter frenulum length and certain jaw growth patterns, but other studies have failed to show a strong direct connection between tongue-tie severity and specific bite problems in adolescents. In orthodontics, a tight frenulum is sometimes released to prevent it from pulling the lower front teeth out of alignment after braces, though this is a less common indication than feeding or speech concerns.
