The frenum is a mucous membrane fold that attaches the lip and the cheek to the alveolar mucosa, the gingiva, and the underlying Periosteum. Abnormal frenum attachment may lead to difficulty in speech, mastication as well as esthetic issues. It may jeopardize the gingival health either due to an interference in the plaque control or due to a muscle pull. The management of such an aberrant frenum is accomplished by performing a frenectomy. The present article is a compilation of a brief overview about the frenum, with a focus on the etiology, indications, contraindications, advantages and the disadvantages of various frenectomy techniques.
