Why are frenectomy stretches recommended, and how long do you do them?

The reasoning behind stretches

A frenectomy wound heals from the base up with nothing holding the two raw surfaces apart. As it heals it also contracts. The argument for stretches is mechanical: if you separate the surfaces briefly and regularly during the weeks the wound is closing, it heals as a wider, deeper release instead of knitting back toward where it started.

That window is short. Wound contraction and remodelling are most active in the first two to four weeks, which is why almost every stretching protocol runs about that long and then stops. Nobody credible asks for stretches for months.

A 2025 prospective study of neonates after frenotomy gives this argument its strongest support. Readhesion occurred in 33.5 percent of that group overall, and families who did not follow the exercise protocol had roughly 1.5 times the risk of readhesion compared with those who did. Older literature puts readhesion lower, around 2.6 to 13 percent, which tells you how much these numbers move depending on who is measuring and what counts as reattachment.

Why major bodies push back, especially for babies

The American Academy of Pediatrics is direct about this. Its guidance says post-frenotomy stretching exercises, in which parents open the wound several times a day to prevent reattachment, have not been proven to help and should not be recommended. The concern is not only that the benefit is unproven, but that repeatedly putting fingers into a newborn's mouth over a fresh wound can create oral aversion, which is the opposite of what the procedure was meant to achieve.

Cleveland Clinic takes the same line for infant frenotomy, stating there is currently no evidence supporting stretching or massaging the wound afterward. The American Academy of Pediatric Dentistry, writing about frenulum management generally, notes that the evidence on timing, indication and technique is limited and calls for better trials.

So the honest position is this: stretching is standard practice in many tongue-tie clinics and has some observational support, while the largest pediatric bodies say the evidence does not justify it in infants. Neither camp is fabricating anything. This is a real gap in the literature.

How to handle conflicting instructions

If your provider gave you a stretching protocol, do not quietly abandon it because of an article, including this one. Go back to them and ask three questions.

• What exactly am I doing, and does it involve opening the wound or only encouraging movement? Active tongue exercises for an older child or adult are a different thing from a parent prying open a newborn's healing wound.
• How many days, and what is my stop date? A protocol without an end date is a warning sign.
• What would make you tell me to stop early? Bleeding each time, a baby refusing feeds, or growing distress at being handled are all reasons to pause and be reassessed rather than push through.
• If my baby develops feeding aversion, who do I call, and will I be seen in person?

Older children and adults are a different case

Most of the controversy above is about newborns. For older children and adults, post-release work is usually not about prying a wound open at all. It is tongue mobility and myofunctional exercises: lifts, sweeps, suction holds and speech drills, done actively by the patient rather than done to them.

That kind of exercise is much less contested. Reviews of laser tongue-tie treatment note explicitly that the procedure does not remove the need for myofunctional exercises and work with a speech therapist, and case series of adult frenuloplasty pair the surgery with therapy as standard. The tongue has spent years working around a restriction, and removing the restriction does not by itself teach it a new pattern.

Results in these series depend heavily on whether the patient actually does the exercises, so if you have had a release as an adult, the therapy is not an optional extra.
