Can My 6-Year-Old Still Have a Frenectomy?

A question I hear often at Bites Odontopediatría in Vitacura is: "isn't it too late to operate on the frenulum? My child is already 6." The short answer: it's not too late.

A frenectomy is not exclusively a baby's surgery. The functional indications appear at different stages of development, and a frenulum that went unnoticed during breastfeeding can start causing real problems later. I'm Dra. Florencia Nogueira, pediatric dentist, and I want to walk you through what we evaluate in older children and why age is not what matters.

How the indications change with age

Babies (0-12 months): the main indication is breastfeeding. Maternal pain, poor weight gain, faulty latch mechanics. The surgery frees the tongue and improves breastfeeding in most cases. Then comes complementary feeding, which is also a problem when the frenulum is restrictive.

Preschoolers (1-5 years): solid feeding begins (difficulty moving the food bolus), language emerges (limitations in sounds that require lifting the tongue: r, l, t, d, n) and, in some cases, postural habits appear, such as mouth breathing associated with a low tongue posture.

School age (6-18 years): two new indications join the list. The first is speech: if a child reaches this age with persistent difficulties in certain sounds and the speech therapist identifies an anatomical limitation, the frenectomy is necessary for therapy to progress. The second is orthodontic: when orthodontic treatment is planned (interceptive or corrective) and the frenulum prevents the tongue from resting against the palate, the frenectomy and subsequent therapy with a speech therapist are necessary. Any orthodontic treatment will fail if we don't correct this.

Three typical scenarios in my practice

Here are three kinds of cases I see regularly in older children:

Scenario 1: the 6-year-old who slurs the r and l sounds. He arrives referred by his speech therapist after months of therapy with limited progress and a suspected restrictive frenulum. On examination, the tongue can't lift freely to the palate and forms a slight heart shape when extended. The catch is that speech therapy has its own subspecialties, and professionals focused on language don't always know how to diagnose a short lingual frenulum. In this case we schedule the frenectomy; specific orofacial motor therapy follows with a speech therapist, and then he continues his language therapy. In three months he'll likely achieve what years couldn't.

Scenario 2: the 8-year-old girl with recurring cavities in her lower molars. Her lingual frenulum is attached in a way that limits the tongue's self-cleaning sweep and also makes those teeth harder to reach with a toothbrush. That leaves the lower arch at risk of plaque buildup and cavities. After one cavity and another already forming, we decided to release the frenulum. The tongue's sweep is restored, hygiene improves, and prevention becomes viable.

Scenario 3: the 10-year-old about to start Invisalign. The orthodontist identifies that the lingual frenulum is restricting the tongue position the treatment result depends on. If orthodontics proceeds with a restricted tongue, the planned movements won't hold over time. The frenectomy happens at the start of orthodontic treatment. The surgery is the same few minutes, but its role is to enable months of orthodontic results.

None of these cases is a baby. None involves breastfeeding. And in all three, the surgery changed something concrete.

What DOES change with age

The indication is the same, but a few details of the procedure change:

Behavioral preparation. A baby needs no explanation. A 6-, 8-, or 10-year-old does. We do a preparation visit where the child gets to know the office, sees the instruments in child-sized versions, and understands what will happen. For many children this is enough, and the surgery happens at a second visit without trouble. If we see significant anxiety, we're open to doing the procedure under conscious sedation with nitrous oxide. Finally, if that doesn't work, it has to be done under general anesthesia in an operating room. So: the earlier it's done, the better.

Anesthesia. In babies, administering anesthesia tends to be more manageable, though it's always injected. In older children, the situation has to be handled carefully so the anesthesia goes as unnoticed as possible. That's often a real challenge.

The child's cooperation in recovery. The post-surgery orofacial motor exercises are easier when the child can cooperate. We talk it through with the child and the parents before operating.

What does NOT change with age

• The procedure is simple and short, just like in babies. The diode laser technique doesn't take longer because the patient is older, especially if they cooperate.
• Recovery is similar in duration: healing takes place between days 10 and 20, just like in babies. The discomfort, though, passes by around day 3 at most. The speech therapist's exercises are practically the same (except that in babies, the parents do them).
• The laser remains the technique of choice for the vast majority of pediatric cases, for its clear advantages. The exceptions (exceptionally thick or deep frenula, or second-time interventions) are assessed case by case.
• There's no visible scar after the first weeks. The area looks like normal pink tissue in most cases.

Why some indications appear late

A question I hear from worried parents: "why did nobody tell me this before?". There are three possible reasons:

1. A short frenulum that didn't compromise breastfeeding can go unnoticed until it compromises other oral functions such as eating, breathing, or speech.
2. Functional diagnosis requires specific expertise. Pediatricians, midwives, lactation consultants, and even speech therapists or dentists not trained in this area can miss a short frenulum that isn't obvious.
3. The child simply hadn't reached the stage where the limitation shows.

If a frenectomy is being suggested for your older child today and nobody mentioned it before, it doesn't mean their care was poor. It means you were consulting in the wrong place.

What the evaluation looks like

The initial consultation takes about 30 minutes. Anatomical exam, functional exam, a conversation with the family, and a clear plan. The decision is never the pediatric dentist's alone: the family understands what the surgery changes, what it doesn't, and what needs accompaniment (speech therapy, orthodontics). If we decide to operate, we do it at a later session, once the child is ready.
