A frenun or frenulum is a thin muscular band that can cause interference with normal function. A frenun is found primarily in 2 areas on the mouth, a labial maxillary frenun and a lingual frenun. Occasionally a patient will have a labial mandibular frenun.

Labial Frenun

A labial frenun can be found in the upper and lower jaw, but primarily in the upper jaw. It ia a small muscular band that connects the upper lip to the gums just above the maxillary central incisors or the lower lip to the gums just below the mandibular central incisors. A prominent labial maxillary frenun can cause a space or gap between the two central incisors. A maxillary labial frenectomy removes the attachment from between the two central incisors.

A labial mandibular frenun is usually less prominent and causes retraction or recession of the gum tissue around the lower incisors. A labial mandibular frenectomy releases this attachment.

Labial frenectomies are very short procedures that only require administration of a local anesthetic.

Lingual Frenun, Ankyloglossus

The lingual frenun attaches the tongue to the floor of the mouth. Sometimes the attachment can extend to the tip of the tongue causing one to be “tongue tied“, also known as ankyloglossia. Release of the excessive attachment is the only option to permit normal tongue function. With ankyloglossia, speech is the most obvious effected tongue function. A lingual frenectomy is a very short procedure and is usually accomplished with a local anesthetic. It is a very rewarding procedure for patients that suffer from ankyloglossia.
