A frenum is a small fold of tissue that connects two parts of the mouth. While normal, if this tissue is too thick, short, or tight, it can cause significant functional limitations. A frenectomy is a minor surgical procedure designed to release or remove this restrictive tissue to restore proper mobility and function. This intervention is recommended when the tissue impairs oral function, such as feeding, speech, or dental health, typically involving the tongue or the lip.
Lingual Frenectomy: Identifying the Need and Consequences
The lingual frenum is the tissue band positioned vertically under the tongue, connecting it to the floor of the mouth. When this tissue is abnormally short or tight, it restricts the tongue’s range of motion, a condition known as ankyloglossia or “tongue tie.”
In infants, a restricted lingual frenum severely affects feeding mechanics. The inability of the tongue to elevate and extend properly prevents the baby from establishing a deep, effective latch, leading to poor milk transfer and inadequate weight gain. Mothers may also experience considerable discomfort or pain during breastfeeding due to the baby’s shallow latch.
As the child grows, limited tongue mobility interferes with the articulation of certain sounds, potentially causing speech impediments. Restricted movement also makes it difficult to clear food debris from the teeth, and in adults, ankyloglossia can be linked to jaw pain and a higher risk of obstructive sleep apnea.
Labial Frenectomy: Identifying the Need and Consequences
The labial frenum connects the inside of the upper lip to the gum tissue, situated between the two upper front teeth. If this frenum is positioned too low on the gumline or is excessively thick, it is referred to as a “lip tie,” causing both functional and aesthetic problems.
In infants, a restrictive upper labial frenum may prevent the lip from flanging outward during feeding. The inability of the lip to fully move interferes with creating a proper seal, leading to issues like clicking sounds during nursing and excessive air intake.
For older children and adults, a prominent labial frenum contributes to the persistence of a diastema, a noticeable gap between the two central incisors. The tissue physically prevents the teeth from coming together, which is often a cosmetic concern.
A tight labial frenum also negatively affects periodontal health by exerting tension on the gum tissue. This tension can pull the gum margin away from the teeth, potentially leading to gingival recession and root exposure. Releasing this tissue helps prevent gum damage, improves oral hygiene access, and ensures successful orthodontic outcomes.
Comparing Surgical Methods
The release of a restrictive frenum can be achieved through a few different surgical techniques. The conventional method involves using a scalpel or surgical scissors to make an incision in the frenum tissue. This technique is quick and straightforward but typically requires sutures to close the wound, especially in labial frenectomies.
A modern alternative is the laser frenectomy, commonly performed using a CO2 or diode laser. The laser uses light energy to precisely cut the tissue while simultaneously cauterizing the blood vessels. This hemostatic effect significantly reduces or eliminates intraoperative bleeding, meaning sutures are often not required and resulting in less tissue trauma.
Patients who undergo a laser frenectomy often report less postoperative pain and discomfort compared to those treated with a scalpel. The laser’s ability to seal nerve endings contributes to a faster recovery period. However, laser procedures involve a higher cost and require specialized equipment and operator training, while the scalpel method remains reliable and widely available.
Recovery Process and Post-Procedure Management
Following a frenectomy, patients can expect a relatively short healing period with mild to moderate soreness. The surgical site will form a small, white or yellowish protective scab, which is a normal protective scab and not a sign of infection. Discomfort is managed effectively with over-the-counter pain relievers, and initial pain usually subsides within 24 to 48 hours.
The most important aspect of post-procedure care is the consistent performance of stretching exercises, often referred to as wound management. These exercises are necessary to prevent the raw tissue edges from fusing back together, which would negate the procedure’s benefits. The specific stretches involve gently lifting the lip or sweeping the finger under the tongue to keep the surgical site open and encourage proper healing. These must be performed multiple times a day for several weeks to maintain the increased range of motion. For infants, care often includes follow-up appointments with specialists, such as a lactation consultant or a speech-language pathologist, to retrain the oral muscles for correct function.
