A frenectomy is not always necessary, and in many cases it can be safely avoided or delayed. The procedure removes or modifies a small band of tissue (a frenulum) that connects the tongue to the floor of the mouth or the upper lip to the gum line. Whether you actually need one depends entirely on the specific problem it’s meant to solve, and for several common reasons people are referred for the surgery, the evidence is surprisingly mixed.
When Breastfeeding Problems Point to Surgery
The most common reason frenectomies are performed on infants is difficulty breastfeeding caused by tongue-tie, a condition where the tissue under the tongue is tight enough to restrict movement. A restricted tongue can impair milk transfer, cause prolonged feeding sessions, limit weight gain, and create significant nipple pain for the mother due to a poor latch. When those symptoms are clearly present and linked to a visible restriction, a frenectomy can help.
But here’s the critical point most parents aren’t told: the American Academy of Pediatrics and the Academy of Otolaryngology both recommend that lactation support be pursued before surgery. Comprehensive approaches that address positioning, latch technique, and ongoing guidance provide sustained benefits that surgery alone cannot match. Not all infants with tongue-tie require surgical intervention, and causes other than tongue-tie are actually more common sources of breastfeeding difficulty. A proper assessment by a lactation specialist should always come first, and many families find that skilled hands-on support resolves feeding problems without any procedure at all.
When conservative support fails and a functional restriction is confirmed, that’s when a frenectomy becomes a reasonable next step. Clinicians sometimes use the Hazelbaker Assessment Tool to score tongue function on a 14-point scale. A score below 11 suggests function is impaired and surgery should be considered if other management hasn’t worked. A score below 8 on the appearance portion indicates a frenectomy is more clearly warranted.
The Speech Connection Is Weaker Than You Think
Many children are referred for tongue-tie release because of speech concerns, but the evidence here is surprisingly thin. A study of 25 children (average age 3.7 years) referred for speech issues thought to be caused by tongue-tie found that 88% of their speech errors were developmentally normal for their age. The most common issues were phonological substitutions and gliding errors, which children typically outgrow. After tongue-tie release, standardized speech scores showed no statistically significant improvement, and the researchers concluded that tongue-tie was not consistently associated with speech articulation errors.
This doesn’t mean tongue-tie never affects speech. Some children do have trouble with sounds that require the tongue to reach the roof of the mouth. But a frenectomy for speech reasons should only be considered after a speech-language pathologist has confirmed that the restriction, not normal development, is the actual problem. Rushing to surgery for speech sounds a child may naturally master in a few months often turns out to be unnecessary.
Closing a Gap Between Front Teeth
A thick or low-attaching upper lip frenulum can contribute to a gap (diastema) between the two front teeth. But even in these cases, the timing and necessity of surgery follow strict guidelines. The American Academy of Pediatric Dentistry recommends postponing any frenectomy until the permanent canines have erupted, because many childhood gaps close naturally once those teeth come in.
When a frenectomy is needed for orthodontic reasons, it should be done after the teeth have already been moved together with braces or aligners, not before. Performing the procedure first can create scar tissue that actually holds the teeth apart. The most predictable results come from combining orthodontic treatment with a frenectomy, rather than relying on the surgery alone. In practice, only a small percentage of children with a gap between their front teeth truly need the procedure.
Adults and Airway Concerns
Adults sometimes discover tongue-tie later in life, particularly when investigating sleep problems or chronic mouth breathing. A restricted tongue can’t press upward against the palate the way it should, which may contribute to a narrow palate, restricted nasal passages, and mouth breathing during sleep. Tongue-tie has also been associated with an increased risk of obstructive sleep apnea in both children and adults.
For adults, a frenectomy is typically paired with myofunctional therapy, a type of physical therapy that retrains the tongue to rest in the correct position, maintain a proper seal, and support nasal breathing. Surgery alone doesn’t retrain years of compensatory habits. Some adults also need orthodontic work to widen a narrow palate or address other structural issues that developed over time.
Laser Versus Traditional Surgery
If a frenectomy is recommended, you’ll likely be offered either a laser procedure or a traditional scalpel approach. Laser frenectomies cause less bleeding during the procedure, less pain afterward, and faster healing in the first week. The laser cauterizes nerve endings and blood vessels as it cuts, which explains the reduced discomfort. At the two-week mark, laser patients also tend to have less scar formation.
By 30 days, however, healing outcomes are equivalent between the two methods. Both techniques have similar long-term success rates, and neither shows a meaningful advantage in preventing the frenulum from reattaching. In some cases, lasers may not fully release deeper muscle fibers, which can slightly increase the chance of reattachment. The choice between the two often comes down to provider preference and patient comfort rather than a significant difference in final results.
Recovery and Preventing Reattachment
After a frenectomy, the wound is intentionally left to heal from the bottom up rather than having the edges close together. This is called healing by secondary intention, and it’s designed to prevent the tissue from simply fusing back into its original position. If the wound margins close too quickly, the restriction can return.
To prevent reattachment, most providers recommend gentle stretching exercises at the surgical site during the healing period. These exercises keep the wound open enough for new tissue to fill in properly. Skipping post-operative care is one of the main reasons a frenectomy fails to produce lasting results, so following through on aftercare is just as important as the surgery itself.
Risks Worth Knowing About
Frenectomies are generally low-risk, but complications do occur. The most concerning is gum recession, where the tissue pulls away from the tooth and exposes the root surface. This is particularly relevant for lip frenectomies near the front teeth, especially in patients who have previously had orthodontic treatment. Orthodontic movement can thin the bone covering tooth roots, and an overly wide incision during surgery can expose that weakened area. In one documented case, a patient developed 4mm of horizontal and 3mm of vertical gum recession on a front tooth after surgery, reducing the long-term prognosis of the tooth.
Scar tissue formation is another consideration. In the mouth, scar tissue can be just as restrictive as the original frenulum, particularly if the surgical technique is imprecise or if aftercare isn’t followed. These risks don’t make frenectomies dangerous overall, but they reinforce why the procedure should only be performed when there’s a clear functional problem that hasn’t responded to less invasive approaches.
