A lingual frenectomy in adults is an oral surgery procedure designed to release a frenulum that clinically restricts tongue movement. Its purpose is not simply to correct a frenulum that appears short, but to improve a function that is affected by that restriction.
For this reason, not every adult with a short lingual frenulum needs a frenectomy. The indication depends on anatomy, actual tongue mobility, symptoms, and their impact on functions such as swallowing, speech articulation, or specific oral movements.
What is ankyloglossia and how is it related to a frenectomy?
The lingual frenulum is a band of tissue located between the underside of the tongue and the floor of the mouth. Ankyloglossia, commonly known as tongue-tie, occurs when this structure restricts tongue mobility.
A meta-analysis that included 71 studies estimated the overall prevalence of ankyloglossia at approximately 5%, but found significant differences depending on the diagnostic method used. Estimates ranged from approximately 2% to 20% depending on the assessment tool. This helps explain why ankyloglossia should not be diagnosed based solely on the appearance of the frenulum.
The lingual frenulum and labial frenulum are not the same
The lingual frenulum is located under the tongue. The labial frenulum connects the inside of the lip to the gums. A lingual frenectomy and a labial frenectomy are therefore different procedures with different indications.
How can you tell whether a lingual frenulum is truly restrictive?
There is currently no single universally accepted diagnostic system for ankyloglossia. For this reason, the evaluation should consider both anatomy and function.
A comprehensive assessment may analyze four areas:
- Anatomy: attachment, tension, and characteristics of the frenulum.
- Mobility: ability to elevate, protrude, and move the tongue from side to side.
- Function: impact on swallowing, speech, and oral movements.
- Symptoms: actual limitations experienced by the patient in everyday life.
The combination of a demonstrable restriction and a functional impact is far more relevant when deciding on treatment than the apparent length of the frenulum alone.
What problems can limited tongue mobility cause?
Some adults with ankyloglossia may have difficulty lifting or extending the tongue, performing certain movements, managing specific oral functions, or articulating certain sounds.
However, not every problem involving speech, swallowing, bite, breathing, or orofacial tension is caused by a restrictive frenulum. Research on several of these associations remains inconsistent, so a differential diagnosis is necessary before surgery is recommended.
When is a lingual frenectomy recommended in adults?
In general, a frenectomy may be considered when several criteria are met:
- There is an objective limitation in tongue mobility.
- The frenulum directly contributes to that restriction.
- The limitation causes a meaningful functional problem for the patient.
- Other possible causes of the symptoms have been considered.
- There is a specific therapeutic goal that may benefit from the release.
In contrast, a short frenulum without symptoms or functional impairment is not, by itself, an indication for surgery.
Two illustrative clinical scenarios
Example 1: an adult has clearly limited tongue elevation and functional difficulties related to certain movements. After evaluating anatomy and function and ruling out other causes, surgical release may be considered to determine whether it could improve the range of motion.
Example 2: another patient has a visible frenulum but moves the tongue normally and has no functional symptoms. In this situation, the presence of the frenulum does not automatically mean that surgery is necessary.
These examples are for illustrative purposes only and do not correspond to specific clinical cases at Clínica Torres.
Frenotomy, frenectomy, and frenuloplasty: what is the difference?
The literature sometimes uses these terms inconsistently, although clinically they can be differentiated as follows:
- Frenotomy: an incision or division of the frenulum to release the restriction.
- Frenectomy: removal of the frenulum or a significant portion of the restrictive tissue.
- Frenuloplasty: release combined with reconstruction or repositioning of the tissues.
The choice depends on the anatomy, the extent of the restriction, and the functional goal. There is no single technique that is universally best for every patient.
How is a lingual frenectomy performed?
Before surgery, a clinical evaluation is performed to determine which structure is restricting movement and what outcome is being sought. If surgery is indicated, the procedure can be performed using different oral surgery techniques.
The process usually includes:
- Medical history and symptom assessment.
- Anatomical and functional examination of the tongue.
- Differential diagnosis.
- Planning of the surgical technique.
- Appropriate anesthesia for the procedure.
- Release of the restrictive tissue.
- Sutures when necessary.
- Postoperative instructions and follow-up visits.
Is laser frenectomy better than scalpel surgery?
Laser and conventional surgery are different tools used to achieve the same goal: properly releasing the restrictive tissue while protecting nearby structures. Some studies describe surgical advantages of lasers, such as improved bleeding control or a reduced need for sutures in certain procedures.
However, the available evidence does not support the conclusion that laser treatment is always superior. The clinical indication, surgical technique, and experience of the professional are more important than choosing a procedure solely based on the technology used.
Speech therapy and myofunctional therapy after tongue-tie release
Improving tongue mobility anatomically does not mean that all functional patterns will change automatically. An adult may have developed compensatory habits over many years.
For certain patients, it may be appropriate to combine surgery with speech therapy or orofacial myofunctional therapy. Scientific literature shows promising results for this combined approach, but the evidence is still limited and does not support considering it mandatory in every case.
Recovery and possible risks of lingual frenectomy
Recovery depends on the type and extent of the surgery. During the first few days, patients may experience tenderness, swelling, or localized discomfort. Follow-up appointments make it possible to monitor healing and determine whether tongue mobility is progressing as expected.
Possible complications include:
- Bleeding.
- Pain and swelling.
- Infection.
- Unfavorable healing or formation of adhesions.
- Injury to nearby structures, which is uncommon when the procedure is properly planned.
- Persistence of some degree of functional restriction.
What results can an adult expect?
The goal most directly related to a frenectomy is to increase the mobility of a genuinely restricted tongue. Other benefits will depend on the specific problem the patient had before the procedure.
Some studies have reported functional improvements after tongue-tie release in adolescents and adults, but evidence specifically involving adult populations remains relatively limited. For this reason, it is not appropriate to guarantee specific improvements in speech, swallowing, sleep, or quality of life before evaluating each case individually.

Frequently asked questions about lingual frenectomy in adults (FAQs)
The price depends on the complexity, surgical technique, and individual needs of each patient. A prior evaluation is necessary to provide an accurate estimate for the case.
The evaluation may be performed by a dentist or healthcare professional trained in oral surgery and frenulum assessment. Depending on the symptoms, coordination with speech therapy, orthodontics, or other specialties may be necessary.
Healing may result in adhesions or residual restriction in some patients. Follow-up visits make it possible to assess the surgical site and monitor changes in mobility.
It may be possible, but the timing should be coordinated with the orthodontic treatment to align dental and functional goals.
There is no universal maximum age. In adults, the decision mainly depends on the presence of functional restriction, overall health, and the balance between potential benefits and risks.
Tongue function determines whether the frenulum needs treatment
A lingual frenectomy in adults may be beneficial when there is a demonstrable restriction of the tongue and that limitation has meaningful functional consequences. Simply having a short frenulum does not mean that surgery is necessary.
The appropriate process is to evaluate anatomy, mobility, function, and symptoms, rule out other causes, and establish a specific therapeutic goal. A specialized evaluation at Clínica Dental Torres allows the frenulum to be assessed within the context of overall oral health and helps determine on an individual basis whether surgery is truly the right option.
