Cutting a frenulum, whether by accident or during a planned procedure, typically causes sharp pain and noticeable bleeding but heals well in most cases. The answer depends heavily on which frenulum is involved, since the human body has several: the lingual frenulum under the tongue, the labial frenulum connecting the lip to the gum, and the penile frenulum on the underside of the penis. Each one responds differently to being cut, and each has its own set of reasons someone might end up in that situation.
Which Frenulum Are We Talking About?
A frenulum is a small fold of tissue that limits the movement of a body part. You have frenula inside your mouth, and if you’re male, one on your penis. The lingual frenulum is the band of tissue connecting the underside of your tongue to the floor of your mouth. The labial frenulum runs from the inside of your upper or lower lip to the gum. Buccal frenula exist in the cheek area as well, connecting to structures near the canine and premolar regions of the jaw.1Cureus. Clinical Anatomy of the Frenulum of the Oral Vestibule The penile frenulum is a thin ridge of tissue on the underside of the penis, just below the glans, that helps retract the foreskin.
When people ask “what happens if you cut your frenulum,” they usually mean one of two scenarios: an accidental tear or a deliberate surgical cut. The outcomes, risks, and recovery differ quite a bit depending on which scenario applies and which body part is involved.
Accidental Tears of the Oral Frenulum
The labial frenulum, especially the one behind the upper lip, is the most commonly torn oral frenulum. It can happen from a fall, a sports injury, or even forceful dental work. In children, a torn upper labial frenulum is frequently seen after tumbles and is usually harmless on its own. The mouth has an excellent blood supply, so there’s often a brief burst of bleeding that looks alarming but stops fairly quickly with gentle pressure. In most cases, a torn labial frenulum heals without stitches or treatment.
One important caveat: in very young children who aren’t yet mobile, a torn frenulum can raise concern about non-accidental injury. Historically, torn frenula in infants were considered a hallmark of child abuse, but the evidence is more nuanced. A systematic review found that accidental labial frenulum tears have been documented, including from medical procedures like intubation.2PubMed Central. Diagnosing abuse: a systematic review of torn frenum and other intra‐oral injuries A forensic pathology review similarly concluded that frenulum tears are not uniquely caused by inflicted injury.3PubMed Central. Are There Hallmarks of Child Abuse? II. Non-Osseous Injuries That said, clinicians still consider a torn frenulum in a pre-mobile infant as one piece of a broader assessment.
Tearing the Penile Frenulum
A torn penile frenulum is one of the more common minor penile injuries, and it tends to happen during sexual activity. The tissue is thin and taut, and a sudden stretch or friction can cause it to tear partially or completely. The immediate result is sharp, stinging pain and bleeding that can seem disproportionate to the size of the injury, since the area has a dense network of small blood vessels.
Most partial tears heal on their own within a couple of weeks if you keep the area clean, avoid sexual activity during healing, and let the tissue recover. The problem is that scar tissue from repeated tears can make the frenulum shorter and tighter, which creates a cycle: the shorter it gets, the more likely it is to tear again, and the more pain it causes during intercourse. When this becomes a recurring issue, the condition is sometimes called frenulum breve, meaning the frenulum is abnormally short. Frenuloplasty, a minor surgical procedure to lengthen or release the frenulum, is the standard fix.
A 12-year review of frenuloplasty outcomes found that the most common reasons patients sought the procedure were tearing and bleeding of the foreskin or pain during intercourse.4PubMed Central. Is frenuloplasty worthwhile? A 12-year experience The procedure is typically done under local anesthesia on an outpatient basis.5International Journal of Impotence Research. Frenuloplasty: from alpha to omega Patient satisfaction tends to be high: one study reported average satisfaction and cosmetic appearance scores of about 9 out of 10, with roughly 97% of patients saying they would recommend the procedure to a friend.6PubMed. Penile frenuloplasty: a simple and effective treatment for frenular pain or scarring About 8% of patients in that study eventually went on to have a circumcision, and 8% experienced minor complications like bruising or partial wound separation.
Penile Frenuloplasty and Premature Ejaculation
An unexpected connection has emerged in the research between a short penile frenulum and premature ejaculation. The frenulum is one of the most sensitive parts of the penis, and when it’s abnormally short, it may be subjected to more tension and stimulation during intercourse. One study found that among men who reported lifelong premature ejaculation, about 43% had a short frenulum. After frenulectomy, the average time to ejaculation increased by about two and a half minutes, and symptom scores dropped significantly.7The Journal of Sexual Medicine. The Role of Short Frenulum and the Effects of Frenulectomy on Premature Ejaculation This is a single study, and the relationship isn’t universally accepted, but it does suggest that for some men, a tight frenulum contributes to more than just pain and tearing.
Tongue-Tie Release in Infants
Intentionally cutting the lingual frenulum is the most common form of frenulum surgery worldwide, and it’s almost always done in babies. Tongue-tie, where the lingual frenulum attaches close to the tip of the tongue and restricts movement, is present in roughly 4% to 11% of newborns and has been cited as a cause of poor breastfeeding and maternal nipple pain.8PubMed Central. Frenotomy for tongue-tie in newborn infants The procedure to release it, called a frenotomy, is quick: a provider snips the frenulum with sterile scissors or a laser, and the baby can typically breastfeed immediately afterward.
Multiple studies have found measurable improvements after lingual frenotomy. One prospective study reported that about 91% of parents noted overall improvement in breastfeeding after the procedure, with significant reductions in breastfeeding pain.9PubMed Central. Effect of frenotomy on breastfeeding variables in infants with ankyloglossia (tongue-tie): a prospective before and after cohort study Another study found that about 90% of mothers reported subjective improvement immediately after frenotomy, and 83% still reported improvement at two weeks.10PubMed. Frenotomy in Infants with Tongue-Tie and Breastfeeding Problems A separate cohort study documented that average breast milk intake improved by about 155% after tongue-tie and lip-tie release.11PubMed Central. Breastfeeding improvement following tongue‐tie and lip‐tie release: A prospective cohort study
In older children and adults, tongue-tie release is done for speech difficulties or restricted tongue mobility. A case report of a 20-year-old woman with moderate tongue-tie documented improvement in speech clarity and tongue movement after conventional surgery, with good healing at follow-up visits over three months.12PubMed Central.

Complications Worth Knowing About
For both oral and penile frenulum procedures, serious complications are uncommon, but they do exist. In the oral realm, a systematic review of major complications after tongue-tie release found cases of poor feeding, excessive bleeding leading to hypovolemic shock, apnea, acute airway obstruction, and a serious deep tissue infection called Ludwig angina.13PubMed. Major complications after tongue-tie release: A case report and systematic review These are rare, but they underscore the point that even a “simple” snip in a newborn requires proper technique and aftercare monitoring.
A study examining a refined surgical protocol for lingual frenuloplasty (a more involved procedure than a simple frenotomy, used in older patients) reported an 86% satisfaction rate with a newer technique, along with notably lower rates of pain, bleeding, and need for revision compared to an earlier protocol. Deeper surgical dissection increased the risk of swelling but didn’t affect overall satisfaction.14International Journal of Orofacial Myology and Myofunctional Therapy. Lingual Frenuloplasty with Myofunctional Therapy: Improving Outcomes for the Treatment of Ankyloglossia (Tongue-Tie) with Refined Techniques and Endpoints
For penile frenuloplasty, as noted earlier, minor complications like bruising, infection, and partial wound separation occur in a small fraction of patients, and most are self-limiting.
Laser Versus Scalpel
If you’re having an oral frenectomy, you’ll likely be offered either a traditional scalpel procedure or a laser approach. The research consistently shows that laser frenectomy causes less pain in the first few days after surgery. A comparative study found that patients who had laser frenectomy experienced significantly less pain, less bleeding, and needed fewer painkillers than those who had the scalpel procedure.15PubMed Central. Frenectomy with conventional scalpel and Nd:YAG laser technique: A comparative evaluation A review of diode laser studies similarly found that laser procedures produced less postoperative pain and accelerated early healing, which is attributed to the laser sealing nerve endings and cauterizing small blood vessels during the cut.16PubMed Central. Efficacy of diode laser on healing in frenectomy compared to conventional frenectomy with scalpel A randomized trial comparing two types of diode lasers against a scalpel confirmed lower intraoperative bleeding, less discomfort with chewing and speaking, and better tissue healing at one week for both laser groups.17PubMed Central. Maxillary labial frenectomy: a randomized, controlled comparative study of two blue (445 nm) and infrared (980 nm) diode lasers versus surgical scalpel
The catch is that at one month, healing outcomes tend to converge. One study found no significant difference in healing between laser and scalpel groups at three months.15PubMed Central. Frenectomy with conventional scalpel and Nd:YAG laser technique: A comparative evaluation Another found that scalpel wounds actually healed faster in the first week (because stitches hold the wound closed), while laser wounds showed less scar tissue formation and all wounds were fully healed by the fourth week.18PubMed Central. Evaluating diode laser and conventional scalpel techniques in maxillary labial frenectomy for patient perception, tissue healing, and clinical efficacy: six-month results of a randomized controlled study So the laser advantage is mainly about comfort in the first week, not long-term healing.
Recovery and What to Expect
Healing after an oral frenectomy is generally straightforward. In the first day or two, expect some soreness and possibly a white or yellowish patch at the wound site, which is normal granulation tissue and not an infection. Most oral frenectomy wounds are fully healed within about four weeks.18PubMed Central. Evaluating diode laser and conventional scalpel techniques in maxillary labial frenectomy for patient perception, tissue healing, and clinical efficacy: six-month results of a randomized controlled study During recovery, you’ll want to avoid spicy or acidic foods that irritate the wound, keep up gentle oral hygiene, and follow any stretching exercises your provider recommends (these are especially important after tongue-tie release, to prevent the tissue from reattaching).
For penile frenulum tears and frenuloplasty, recovery involves abstaining from sexual activity for several weeks, keeping the area clean, and watching for signs of infection. Most men are fully healed and can resume normal activity within four to six weeks.
For laser procedures specifically, the initial charring and carbonization of the wound edges can produce a slightly delayed start to visible healing compared to scalpel surgery, but the laser-created coagulation layer acts as a natural wound dressing that reduces irritation and tends to result in less scar tissue.19PubMed Central.

The Tongue-Tie Diagnosis Boom
One thing worth understanding if you’re a new parent researching tongue-tie: the rate at which tongue-tie is being diagnosed and surgically treated has increased dramatically over the past two decades. In Canada, the diagnosis rate more than tripled from about 7 per 1,000 live births in 2002 to nearly 23 per 1,000 in 2014.20PubMed Central. Changes in the incidence and surgical treatment of ankyloglossia in Canada In the United States, the annual rate of diagnosis rose from under 1% in 2010 to about 4% in 2022, though the rate of surgical treatment plateaued after 2018.21PubMed. Plateau in Growth or Losing Influence? Costs and Shifting National Trends of Ankyloglossia Treatment 2010-2022
This surge has sparked genuine controversy among healthcare professionals.22PubMed. Controversy Over Tongue-Tie: Divisions in the Community of Healthcare Professionals Part of the concern is that increased awareness, particularly through social media, has led to the medicalization of normal anatomical variation. A study examining social media content about tongue-tie found that diagnosis of oral ties is increasing partly due to online information, leading to more frenotomies and potential over-treatment of often normal anatomy.23PubMed Central. Misinformation and Readability of Social Media Content on Pediatric Ankyloglossia and Other Oral Ties Another analysis flagged how social media encourages parents to seek non-evidence-based therapies for common infant concerns like breastfeeding difficulties.24PubMed Central. Challenges to Infant Health Care in the Social Media Era: Misinformation and Medicalisation
The evidence does support that frenotomy helps carefully selected infants with genuine breastfeeding difficulties tied to a restrictive lingual frenulum. Clinical guidelines advise both anatomical and functional assessment before deciding to proceed.25Pediatric Dentistry. Evidence-Based Clinical Practice Guideline for Assessment and Management of Ankyloglossia in Infants With Breastfeeding Difficulties But the existing assessment tools for tongue-tie severity haven’t been shown to reliably predict which patients will benefit from surgery.26PubMed Central. Effectiveness of tongue-tie assessment tools in diagnosing and fulfilling lingual frenectomy criteria: a systematic review In other words, the procedure works for the right patients, but identifying who those patients are remains frustratingly imprecise.
Oral Piercings and Frenulum Damage
There’s another way frenula get cut or damaged that doesn’t involve surgery or accidents: oral piercings. Tongue piercings and, less commonly, frenulum piercings (sometimes called “smiley” piercings for the upper labial frenulum or “frowny” for the lower) put the tissue at ongoing risk. A scoping review of oral piercing complications found that among patients with oral piercings, 96% reported local complications. These included persistent mucosal atrophy in 70% of cases, as well as swelling, redness on the palate, and tooth sensitivity.27PubMed Central. Oral Piercing: A Pretty Risk—A Scoping Review of Local and Systemic Complications of This Current Widespread Fashion The frenulum itself is thin and can tear easily from jewelry movement, and a piercing that migrates or catches on teeth can effectively sever the tissue over time. Unlike a clean surgical cut, this kind of gradual damage is harder to manage and can lead to gum recession where the jewelry rubs against the gumline.
If a frenulum piercing tears out entirely, the tissue may heal with a gap or irregular scar. Some people report that a torn labial frenulum piercing causes no lasting problems once the jewelry is removed and the wound heals. Others, particularly those with damage near the gumline, end up with localized gum recession that doesn’t reverse on its own. The risk profile is quite different from a surgical frenectomy, where the cut is controlled and placed to minimize collateral tissue damage.
