Cutting a frenulum is a real medical procedure performed thousands of times a day around the world, but the word “frenulum” refers to several different structures in the body, each with its own reasons for intervention and its own risks. Whether the concern is a baby struggling to breastfeed, a gap between a child’s front teeth, or pain during sex from a tight penile frenulum, the short answer is yes, these tissues can be surgically released. The longer answer involves knowing when cutting is genuinely warranted, what can go wrong, and why a growing number of clinicians worry that frenulum procedures are being performed far more often than the evidence supports.
Which Frenulum Are We Talking About
The human body has several frenula, which are small folds of tissue that anchor a moving structure to a nearby surface. The three that generate the most questions are the lingual frenulum (the band under the tongue), the maxillary labial frenulum (the strip of tissue connecting the upper lip to the gum above the front teeth), and the penile frenulum (the small band on the underside of the glans). Each one can sometimes be too short or too tight, restricting normal movement or causing pain, and each has its own surgical release procedure.
The lingual frenulum is by far the most discussed. Histological studies show it is not a discrete ligament but rather a fold of floor-of-mouth tissue rich in Type III collagen, with the densest concentration right at the midline where you can see and feel it beneath the tongue.1PubMed Central. Understanding the Lingual Frenulum: Histological Structure, Tissue Composition, and Implications for Tongue Tie Surgery There are no muscle fibers running through it; it is connective tissue, which is why a simple snip can release it. The labial frenulum is similar in composition but sits between the lip and gum, while the penile frenulum is a distinct mucosal fold with sensory nerve endings.
When Cutting the Lingual Frenulum Is Medically Justified
The most common reason for cutting a lingual frenulum is ankyloglossia, commonly called tongue-tie, in infants who are having difficulty breastfeeding. A short or tight lingual frenulum can prevent a baby from latching properly, leading to poor milk transfer and nipple pain for the mother. A meta-analysis of randomized trials found that frenotomy produced statistically significant improvements in both breastfeeding difficulty scores and maternal pain scores compared to sham procedures.2PubMed. Systematic review of the evidence for resolution of common breastfeeding problems-Ankyloglossia (Tongue Tie)
That said, the picture is more complicated than it appears. One review noted that improvements observed immediately after the procedure may partly be a response to the pain of the cut itself, since sucking is a self-soothing behavior for infants, and no published studies have controlled for this effect.3PubMed Central. What is tongue-tie and does it interfere with breast-feeding? – a brief review Feeding difficulties have many possible causes, and a short frenulum is just one of them. A baby who struggles to latch might have positioning issues, a high palate, or other anatomical factors that cutting the frenulum will not fix.
The Overdiagnosis Problem
One of the biggest concerns in this field is the dramatic increase in tongue-tie diagnoses. Between 2012 and 2016, reported diagnoses of ankyloglossia in U.S. inpatient settings rose by over 110%, with a similar jump in the number of frenotomy procedures performed.4PubMed. Ankyloglossia: Update on Trends in Diagnosis and Management in the United States, 2012-2016 That increase has continued, and it raises uncomfortable questions about whether the condition is genuinely becoming more common or whether diagnostic criteria have loosened so much that normal anatomical variation is being labeled a problem.
A cross-sectional study of breastfed infants referred for tongue-tie assessment found that over 92% of referred babies received a tongue-tie diagnosis, with an estimated population prevalence of about 11% among breastfed infants in that region.5PubMed Central. A cross-sectional study of breastfed infants referred for tongue tie assessment and frenotomy in one Canadian health region Two-thirds of those diagnosed went on to have a frenotomy. The high diagnosis rate among referrals suggests either that referral criteria are very accurate or, more likely, that once a baby is referred with a suspected problem, clinicians tend to confirm it. The study found that nipple pain, inability to latch, inability to elevate the tongue, and dimpling of the tongue on extension were the factors most strongly associated with a decision to cut.
There is no universally accepted grading system for tongue-tie severity, and “posterior tongue-tie,” a category that has become popular in recent years, remains especially controversial. Many babies diagnosed with posterior ties have frenula that look entirely normal to clinicians who do not use that category. The lack of standardized diagnostic criteria means that whether a baby gets a frenotomy can depend heavily on which practitioner the family sees.
Does Tongue-Tie Actually Cause Speech Problems
Parents of older children are sometimes told that a tongue-tie is causing speech difficulties, but the research on this is surprisingly thin. A systematic review found no clear connection between ankyloglossia and speech disorders.6PubMed. The effect of ankyloglossia and tongue-tie division on speech articulation: A systematic review A separate study comparing young children with treated tongue-tie, untreated tongue-tie, and no tongue-tie found no statistically significant differences between the groups in tongue mobility, speech production, or intelligibility.7PubMed. Speech production in young children with tongue-tie
A clinical study that looked at children referred specifically for speech concerns believed to be caused by tongue-tie found that most of them had age-appropriate speech errors at the time of evaluation. Tongue-tie release did not improve speech articulation or intelligibility in that group.8PubMed. The Effect of Tongue-Tie Release on Speech Articulation and Intelligibility This does not mean tongue-tie never affects speech, but it does suggest that the connection is overstated and that many children are undergoing procedures for speech reasons without good evidence that the procedure will help.
The Lip-Tie and Dental Connection
The maxillary labial frenulum, the tissue between the upper lip and the upper gum, generates a different set of concerns. A thick or low-attaching labial frenulum can contribute to a gap between the upper front teeth, make oral hygiene harder by trapping food and plaque, and in some cases restrict upper lip movement enough to affect feeding in infants.9Journal of the Korean Academy of Pediatric Dentistry. Management of the Maxillary Labial Frenum
However, a scoping review of the evidence on labial frenulum treatment found that midline gaps between the front teeth often close on their own as children grow, particularly after the permanent canine teeth come in. The review concluded that surgical intervention is only advisable when the frenulum is actively interfering with oral hygiene or contributing to orthodontic relapse after braces.10Journal of Dentistry for Children. Maxillary Labial Frenulum: A Scoping Review of Classification, Diagnosis and Evidence-Based Treatment In short, early frenectomy for a gap between baby teeth is rarely necessary and should not be rushed.
Penile Frenulum Breve
The penile frenulum connects the underside of the glans to the foreskin (or its remnant in circumcised men). When this band is abnormally short, a condition called frenulum breve, it can cause pain during erection and intercourse and may tear during sexual activity. A short frenulum is a common cause of pain during sex in men.11The Journal of Sexual Medicine. Male Dyspareunia Due to Short Frenulum: The Suture-Free, “Pull and Burn” Method
If you have torn your penile frenulum during sex, the immediate concern is usually bleeding, which can be managed with firm pressure and keeping the area clean. A single tear often heals on its own over a few weeks if you avoid sexual activity during that time. The real question is whether the frenulum remains too tight after healing, in which case it may tear again. Men who experience recurrent tears or ongoing tightness have a surgical option called frenuloplasty, which lengthens or releases the frenulum without requiring a full circumcision. A study of 106 patients who underwent penile frenuloplasty reported average satisfaction scores of about 9 out of 10, with 97% of patients saying they would recommend the procedure. Only about 8% went on to need a circumcision afterward, and minor complications like bruising or partial wound separation occurred in a similar proportion.12PubMed. Penile frenuloplasty: a simple and effective treatment for frenular pain or scarring
Frenuloplasty is performed under local anesthesia and typically takes about 15 to 30 minutes. It is a minor day procedure. The key point is that this should be done by a urologist or surgeon, not attempted at home. Self-cutting of the penile frenulum carries serious risks of uncontrolled bleeding, infection, nerve damage, and scarring that could make the problem worse.
The Real Dangers of Cutting a Frenulum
Even in professional settings, frenulum procedures carry risks. A systematic review of major complications after tongue-tie release identified 47 serious adverse events across 34 patients, including poor feeding after the procedure, blood loss severe enough to cause shock, breathing obstruction, and serious infections of the floor of the mouth.13PubMed. Major complications after tongue-tie release: A case report and systematic review These severe outcomes were rare, but the fact that they occurred at all underlines that this is not a trivial snip.
A survey of healthcare professionals about complications they had seen or treated after infant frenotomy found that the most frequently reported issues were a repeat procedure being considered or performed (about a third of cases) and oral aversion, where the baby becomes reluctant to feed (reported in roughly 28% of cases). Bleeding was more common when scissors or a scalpel were used, while oral aversion was about four times more likely when laser or electrosurgery instruments were involved.14PubMed Central. Complications and misdiagnoses associated with infant frenotomy: results of a healthcare professional survey That finding complicates the popular assumption that laser procedures are always gentler.
The danger increases substantially when procedures are performed by inadequately trained providers or, worse, attempted at home. Online communities, particularly those focused on appearance-related self-improvement, have normalized discussions of DIY body modifications that include cutting frenula. Research into social media “looksmaxxing” communities has documented how dangerous practices become normalized through pseudoscientific language and community validation, with tutorial content receiving high engagement especially among young men.15Elsevier / Journal of Stomatology, Oral and Maxillofacial Surgery. Dangerous trends on social media related to facial esthetics: Analysis of looksmaxxing and its softmaxxing and hardmaxxing practices Anyone considering cutting their own frenulum based on internet advice should understand that uncontrolled bleeding, infection, and permanent nerve damage are real possibilities, not scare tactics.
Scalpel, Scissors, or Laser
For oral frenulum procedures, the main surgical options are traditional cutting instruments (scissors or scalpel) and laser. A clinical comparison found that laser-assisted frenectomy produced significantly less pain both immediately after surgery and at one week, with faster healing and no need for sutures in the laser group.16PubMed Central. Clinical Comparison of Diode Laser Assisted “v-Shape Frenectomy” and Conventional Surgical Method as Treatment of Ankyloglossia However, a randomized controlled trial in infants comparing diode laser to scalpel frenotomy found that both groups showed significant functional improvements and weight gain, with no significant differences between the groups on most outcomes. The scalpel group actually performed slightly better on breastfeeding assessments at one week.17PubMed Central. Diode laser versus scalpel in the surgical treatment of infant ankyloglossia: a randomized, parallel, double-blind, controlled clinical trial
The takeaway is that neither method is clearly superior for infant tongue-tie. Laser may reduce bleeding during the procedure and may cause less immediate pain in some studies, but the functional outcomes are comparable, and laser carries its own risk of thermal injury to surrounding tissue. The choice of instrument matters less than the skill and judgment of the person wielding it.
Pain Control in Infants
A surprisingly unsettled area is how much pain a frenotomy actually causes and how to manage it. A Cochrane review noted that whether frenotomy is a painful procedure requiring analgesia has not been established, because no study has adequately quantified infant pain during and after the procedure.18Cochrane Database of Systematic Reviews. Frenotomy for tongue‐tie in newborn infants Studies comparing topical anesthetics to no anesthesia in very young infants found no meaningful difference in pain response, suggesting that the numbing gels commonly applied before a snip may not be doing much.19PubMed Central. How to Treat a Tongue-tie: An Evidence-based Algorithm of Care Many practitioners rely on breastfeeding or sucrose drops immediately after the procedure to soothe the baby, rather than on the anesthetic itself.
Post-Procedure Wound Stretches
If you have had your baby’s tongue-tie released, you have almost certainly been told to perform wound stretching exercises, lifting the tongue and running a finger under it several times a day to prevent the tissue from reattaching as it heals. These exercises are standard advice but widely dreaded by parents, who often describe them as distressing for both baby and caregiver. The question of whether they are genuinely necessary has now been addressed by several studies.
A prospective study found that families who adhered to their stretching protocol had zero persistent feeding difficulties, compared to roughly 15-16% in both the non-adherent and non-stretching groups. Recurrent tongue-tie occurred in about 6% of the adherent stretching group versus 41% of those who were told to stretch but did not follow through.20PubMed. Outcomes of stretching exercises after lingual frenotomy in infants: A prospective, interventional study A separate observational study confirmed that following the exercise protocol roughly halved the risk of tissue readhesion.21PubMed Central. Readhesion of Tongue-Tie Following Neonatal Frenotomy: Incidence and Impact of Postoperative Exercises in a Prospective Observational Study The evidence is reasonably strong that if you are going to have the procedure done, committing to the aftercare exercises meaningfully reduces the chance of needing a repeat procedure.
An important nuance in the stretching data: families who started the stretching protocol but did not stick with it had worse outcomes than families who never stretched at all. In the non-adherent group, 37% needed a revision procedure, compared to 32% of those who never stretched and just 6% of those who followed through consistently.20PubMed. Outcomes of stretching exercises after lingual frenotomy in infants: A prospective, interventional study The likely explanation is that inconsistent stretching partially disrupts the healing wound without fully preventing reattachment, creating more scar tissue than if the wound had simply been left alone.
Non-Surgical Alternatives
For breastfeeding difficulties associated with tongue-tie, some families pursue conservative approaches: bodywork (craniosacral therapy, chiropractic), suck training exercises, or working intensively with a lactation consultant to optimize positioning and latch. A systematic review of these alternative therapies found that while some studies suggested potential benefits when combined with surgery, nonsurgical approaches alone currently lack sufficient evidence to recommend them as standalone treatments.22PubMed. Alternative Therapies for Ankyloglossia-Associated Breastfeeding Challenges: A Systematic Review
That does not mean conservative approaches are worthless. Many feeding difficulties that get attributed to tongue-tie resolve on their own as the baby grows and develops better oral motor control. A period of working with a skilled lactation consultant, trying different positions, and giving the baby time may produce improvement without surgery. The difficulty is that when a parent is exhausted and a baby is losing weight, “wait and see” can feel unconscionable, which partly explains why frenotomy rates have climbed so sharply.
Who Should Be Performing These Procedures
The qualifications of the person performing a frenulum procedure vary widely depending on the type. Penile frenuloplasty is a urological procedure typically performed by a urologist or surgeon in a clinical setting. Oral frenectomy and frenotomy, however, exist in a regulatory gray zone. The systematic review of major complications found that the professionals performing the procedures ranged from otolaryngologists and pediatric surgeons to dentists and lactation consultants.13PubMed. Major complications after tongue-tie release: A case report and systematic review In some institutions, midwife lactation consultants have been credentialed to perform infant frenotomies, a practice that is established in at least some tertiary maternity hospitals.
The diversity of providers is not inherently dangerous, since a simple anterior frenotomy in a newborn is a quick procedure with minimal tissue involvement. The risk increases with more extensive procedures, particularly those marketed as “posterior tongue-tie release” or “complete release,” which involve cutting deeper into the floor of the mouth. Those procedures should be reserved for trained surgeons who can manage bleeding, airway complications, and the rare but serious infections that can follow. If you are shopping for a provider and they are recommending a procedure that involves general anesthesia or extensive tissue removal, seek a second opinion from someone who has no financial interest in performing the procedure.
Frenulum Complications That Resolve Without Surgery
Not every frenulum problem requires a knife. In infants, many breastfeeding difficulties improve over the first few weeks as both baby and mother get more practice. The maxillary labial frenulum often thins and migrates upward as the jaw grows, which is why the gap between a toddler’s front teeth frequently closes by the time the permanent canines erupt. For penile frenulum issues, a single tear during sex is common and usually heals without intervention if the area is kept clean and given rest. Even mild chronic tightness can sometimes be managed with gentle stretching techniques over time, though the evidence for this approach is largely anecdotal.
The thread connecting all these situations is that frenulum tissue is not static. It changes with growth, healing, and use. Rushing to cut may solve a problem that would have resolved on its own, while also introducing the risks of bleeding, infection, scarring, and in the case of infants, oral aversion that can make feeding harder rather than easier. That calculus is worth sitting with, especially when the person recommending the procedure also happens to be the one billing for it.
