What Is A Frenectomy?

A frenectomy is a minor surgical procedure that removes or modifies a small fold of tissue called a frenum. You have several frena (the plural form) in your mouth. The most common ones are under your tongue and inside your upper and lower lips. These small bands of tissue help anchor moving parts, but sometimes they are too tight or positioned in a way that causes problems. When that happens, a doctor or dentist may recommend a frenectomy to release the tissue and restore normal function.

What Is A Frenectomy and Why Would Someone Need One?

A frenectomy is performed when a frenum interferes with normal movement or function. In newborns and infants, the most common reason is a condition called ankyloglossia, better known as tongue-tie. When the tissue under the tongue is too short or tight, it can restrict tongue movement. This can make breastfeeding difficult for the baby and painful for the mother.

In older children and adults, frenectomies are often done for speech issues, orthodontic reasons, or gum recession. A tight upper lip frenum can create a gap between the front teeth. It can also pull the gum tissue away from the teeth over time. A lower lip frenum can contribute to gum recession on the lower front teeth.

The procedure itself is simple. A clinician numbs the area with a local anesthetic. Then they cut or use a laser to release the tissue. The entire procedure usually takes less than 30 minutes. Most people heal within a week or two.

What Are the Different Types of Frenectomy?

There are two main types of frenectomy. The first is a lingual frenectomy, which involves the tissue under the tongue. This is the procedure most often used to treat tongue-tie. The second is a labial frenectomy, which involves the tissue inside the upper or lower lip. This is often done to close a gap between teeth or prevent gum recession.

Some clinicians also perform a buccal frenectomy. This involves the frena located in the cheeks, near the back molars. These are less common but can sometimes pull the gums away from the back teeth.

The approach can also vary. A traditional frenectomy uses a scalpel. A newer approach uses a laser. Both methods remove the same tissue. Laser procedures tend to cause less bleeding and may reduce post-operative discomfort, but the long-term results are similar. The choice often comes down to clinician preference and available equipment.

What Is a Frenotomy and How Is It Different?

You may hear the terms frenotomy and frenectomy used almost interchangeably. They are not the same thing, though the difference matters mostly for precision.

A frenotomy is a simple snip. The clinician makes a single cut to divide the frenum. No tissue is removed. A frenectomy removes the entire frenum. This is a more complete release.

For infants with tongue-tie, a frenotomy is often sufficient. The tissue is thin and the goal is simply to free the tongue. For older children and adults, a frenectomy is more common because the tissue is thicker and more fibrous. Removing the full band reduces the chance that it reattaches during healing.

Does a Frenectomy Hurt and What Is Recovery Like?

The procedure itself is not painful because the area is numbed. Infants may not even need anesthetic, though many practitioners apply a topical numbing gel. Older children and adults receive a local injection similar to what you would get for a filling.

After the numbing wears off, there is some discomfort. Most people describe it as a mild soreness, similar to a canker sore or a minor burn. Over-the-counter pain relievers are usually enough to manage it.

For the first few days, you may notice a white or yellowish patch where the tissue was removed. This is normal. It is not an infection. It is the body forming new tissue as it heals. This patch usually disappears within a week.

Eating soft foods for the first day or two makes sense. Avoid spicy, acidic, or crunchy foods that could irritate the site. Good oral hygiene is important, but be gentle near the healing area.

One of the most important parts of recovery is stretching. After a frenectomy, the tissue can reattach as it heals. To prevent this, clinicians recommend specific exercises that move the tongue or lip in certain directions. These are usually done several times a day for a few weeks. Skipping these exercises is the most common reason a frenectomy does not achieve the desired result.

Are There Risks or Complications From a Frenectomy?

Frenectomies are low-risk procedures, but they are not zero-risk. The most common complications are bleeding, infection, and reattachment of the tissue. All of these are manageable.

Bleeding is usually minimal and stops quickly. Persistent bleeding is rare but should be reported to your clinician. Infection is uncommon but possible. Signs include increasing pain, swelling, or discharge from the site. Reattachment is the most frustrating complication because it means the original problem may return. This is why the stretching exercises matter so much.

There is also the question of whether the procedure actually solves the problem it was intended to fix. This is especially true for tongue-tie in infants. Some research shows clear benefits for breastfeeding. Other studies show mixed results, particularly when tongue-tie is diagnosed in older children for speech issues.

Speech is complex. Many factors contribute to articulation problems. Releasing a tight frenum does not guarantee that speech will improve. It removes one potential obstacle. If other issues are present, speech therapy may still be needed.

Similarly, closing a gap between teeth with a frenectomy is not always permanent. The frenum can pull the teeth apart again if the gap is large. Many orthodontists recommend a frenectomy as part of a larger treatment plan that includes braces or aligners.

When Is a Frenectomy Recommended in Infants?

Infant frenectomies are usually recommended when breastfeeding is not working well. Signs include a baby who struggles to latch, falls asleep at the breast, or makes a clicking sound while feeding. Mothers may experience significant nipple pain or damage. These signs together suggest a tongue-tie may be limiting the baby’s ability to move milk effectively.

Not every tongue-tie needs treatment. Many babies with a tight frenum breastfeed perfectly well. The decision to intervene should be based on function, not on the appearance of the tissue alone.

When a frenotomy is performed in the first few weeks of life, it is quick. The baby is swaddled, the tissue is lifted, and a single snip releases it. The baby often settles immediately and can breastfeed right away. Healing is fast, and complications are rare.

Some parents worry about pain in a newborn. The procedure is very fast, and the discomfort is brief. Many clinicians use a topical anesthetic or a sugar solution on a pacifier to soothe the baby. Long-term effects on infants are not well studied, but the immediate benefits for breastfeeding are well documented.

What Does the Evidence Say About Frenectomy Outcomes?

The evidence is strongest for infant frenotomy and breastfeeding. Multiple studies have shown that releasing a tongue-tie improves latch and reduces maternal nipple pain. This is the most well-established benefit of the procedure.

The evidence is weaker for other indications. Speech outcomes are mixed. Some children improve after a frenectomy, but not all. The evidence does not support routine frenectomy for speech delays without a clear functional limitation.

Orthodontic outcomes are also mixed. A frenectomy can help close a small gap between the front teeth. For larger gaps, the frenectomy alone is not enough. It must be combined with orthodontic treatment.

Gum recession from a tight labial frenum is a real phenomenon. Releasing the tissue can prevent further recession. Whether it reverses existing recession is less clear. In some cases, a gum graft is also needed.
