Frenectomy is a minor oral surgical procedure that removes or releases a frenum — a small fold of connective tissue that attaches the lips, cheeks, or tongue to the underlying gingiva or floor of the mouth. When a frenum is unusually tight, thick, or positioned in a way that restricts movement or causes dental complications, a frenectomy may be clinically indicated.
Types of Frenectomy
There are two primary types, each targeting a distinct anatomical site:
- Labial frenectomy: Addresses the maxillary labial frenum — the tissue connecting the upper lip to the gingiva between the central incisors. A low-inserting or fibrous frenum can cause a diastema (midline gap) and may compromise orthodontic treatment stability if not corrected.
- Lingual frenectomy: Also called a frenotomy or tongue-tie release, this procedure targets the lingual frenum beneath the tongue. Restriction here — clinically termed ankyloglossia — can impair speech articulation, swallowing, and breastfeeding in infants.
Clinical Significance
A frenectomy may be recommended across a range of scenarios, including:
- Prevention or closure of a maxillary midline diastema, typically coordinated with orthodontic care
- Correction of ankyloglossia affecting feeding, speech development, or oral hygiene
- Improving complete denture stability by eliminating frenal tissue that disrupts prosthetic seating
- Reducing periodontal risk where frenal pull contributes to gingival recession or attachment loss
How the Procedure Works
Frenectomies are performed under local anesthesia and are generally well-tolerated in both pediatric and adult patients. The frenum may be excised using a scalpel, electrosurgical unit, or soft-tissue laser. Laser-assisted techniques are increasingly preferred for their precision, reduced intraoperative bleeding, and minimal post-operative discomfort. Healing typically occurs within one to two weeks, with sutures placed only when the excision site requires primary closure.
Post-operative stretching exercises are often prescribed — particularly following lingual frenectomies — to prevent reattachment of the frenal tissue and support functional improvement over time.
When a restrictive frenum is identified and treated appropriately, a frenectomy can meaningfully improve speech development, orthodontic outcomes, and long-term periodontal health.
