A frenectomy is a minor procedure that releases a tight band of tissue (called a frenulum) under an infant’s tongue or behind the upper lip. It’s performed when that tissue restricts tongue movement enough to interfere with breastfeeding, and it typically costs between $500 and $1,500 depending on the method used and the clinical setting. Most infants recover within two weeks, though aftercare stretches play a major role in the outcome.
Why Some Infants Need a Frenectomy
Every baby is born with a frenulum connecting the tongue to the floor of the mouth, and another connecting the upper lip to the gum. In some infants, these bands of tissue are unusually short, thick, or tight, restricting the tongue’s range of motion. When this restriction causes feeding problems that don’t improve with lactation support, it’s called symptomatic ankyloglossia, commonly known as tongue-tie.
Signs that a tight frenulum is causing real problems include poor latch during breastfeeding, inadequate weight gain, and persistent nipple pain or trauma for the mother. Some infants also show coughing, choking, long feeding times, or difficulty staying attached to the breast. On physical exam, a tied tongue often can’t extend past the lower gum line or lift halfway to the roof of the mouth, and the tongue tip may appear heart-shaped when the baby tries to stick it out.
Nipple pain alone isn’t enough to justify a frenectomy. Between 34% and 96% of breastfeeding mothers experience nipple pain in the first days after birth, and for most women it peaks around day three and drops to mild levels within seven to ten days. When pain persists well beyond that window and the baby shows visible restriction, a frenectomy becomes a reasonable option.
How Doctors Assess Tongue-Tie Severity
Clinicians use structured scoring tools rather than eyeballing the tissue alone. The Bristol Tongue Assessment Tool (BTAT) is one of the most common. It evaluates four things: the appearance of the tongue tip, where the frenulum attaches along the gum ridge, how well the baby can lift the tongue, and how far the tongue can protrude. A low score across these categories, combined with documented feeding difficulties, builds the case for intervention.
Before recommending a frenectomy, providers should rule out other causes of feeding trouble. The American Academy of Pediatric Dentistry recommends evaluating for nasal obstruction, airway issues, reflux, and craniofacial differences first. This is especially important for very young newborns under two weeks of age, where rushing to surgery could mean treating the wrong problem.
Scissor vs. Laser Frenectomy
The two main approaches are surgical release with scissors or a scalpel, and laser release using a high-powered diode or similar device. Both achieve the same goal of cutting or removing the restrictive tissue, and both leave the wound open to heal on its own without stitches.
Laser frenectomy offers some theoretical advantages: better control of bleeding through microvascular sealing, more precise cutting, and improved visibility during the procedure. However, a randomized controlled trial comparing diode laser to scalpel found no significant difference in healing quality between the two methods at 14 days. The wounds healed at similar rates regardless of technique.
One notable finding from that same trial: at one week post-procedure, the scalpel group actually showed significantly better breastfeeding scores on both the LATCH and IBFAT assessment scales. By day 14, those differences disappeared, and both groups had equivalent outcomes. So while laser is often marketed as the gentler option, the clinical evidence suggests the tools perform similarly in the end. Higher laser energy during the procedure was also linked to less favorable healing at two weeks, meaning more isn’t necessarily better when it comes to laser power.
Bleeding was minimal with both methods in the trial, and no patients experienced postoperative bleeding, infection, or reattachment during the study period.
What to Expect During Recovery
Recovery from an infant frenectomy is quick compared to most surgical procedures, but it does require active participation from parents. The wound under the tongue or behind the lip heals by forming new tissue from the edges inward, and without regular stretching, that healing tissue can tighten and effectively reattach the frenulum.
The aftercare stretching protocol is intensive in the first two weeks. Most providers recommend five to six stretch sessions per day, roughly every three hours, including one session in the middle of the night. For the upper lip, you slide a clean finger under the lip and push it up until you feel gentle resistance, then sweep side to side for a second or two. Tongue stretches involve lifting the tongue toward the roof of the mouth. Starting in the second week, many protocols increase to about five lifts per session.
By weeks three and four, you can typically reduce to three or four sessions a day and drop the overnight session, especially if your baby is sleeping through the night. The stretches aren’t comfortable for your baby, and short fussing is normal, but they’re a critical part of preventing the need for a repeat procedure.
Revision Rates and Follow-Up Timing
About 9% of infants who undergo a frenotomy end up needing a revision procedure. Interestingly, the timing of the first follow-up visit appears to matter. In a study of 369 infants, those seen at one week post-procedure had a revision rate of just 5.2%, while those whose first follow-up was at two weeks had a 12.7% revision rate. The two-week group had 2.67 times the odds of needing a revision compared to the one-week group.
This doesn’t necessarily mean waiting longer causes reattachment. It likely reflects the value of early follow-up: catching incomplete healing sooner, correcting stretching technique, and addressing any issues before scar tissue has time to firm up. If your provider offers a one-week check, take it.
Upper Lip Tie: Less Clear-Cut
While tongue-tie has a growing body of evidence behind it, upper lip tie is more controversial. Some practitioners point to poor lip flanging, lip dimpling, blanching of the tissue when the lip is lifted, and even reshaping of the gum ridge as signs of a problematic upper lip frenulum. However, the American Academy of Pediatrics notes that these signs lack supporting evidence in the peer-reviewed literature.
For older children, a tight upper lip frenulum can create a gap between the front teeth, but pediatric dentists and orthodontists generally agree that most of these gaps close naturally as permanent teeth come in. The recommendation is to avoid surgical correction of an upper lip frenulum before the permanent canine teeth erupt, and only then in conjunction with orthodontic treatment if the gap persists.
Cost and Insurance Coverage
A single frenectomy typically runs $500 to $1,500, with the price varying based on the technique (laser tends to cost more), whether anesthesia beyond topical numbing is used, and whether the procedure is done in a private office or hospital setting. The procedure can be billed through medical or dental insurance using specific procedure codes for either the tongue or lip frenulum, but coverage varies widely by plan. Some families pay entirely out of pocket, especially for laser procedures performed by pediatric dentists. It’s worth calling your insurance ahead of time with the specific procedure code to get a clear answer on what’s covered.
