A mucous membrane fold that attaches the cheek and the lip to the gingiva, the alveolar mucosa, and the underlying periosteum is called frenum. They run the risk of causing a muscle pull or restricting plaque control if they are attached too closely to the gingival margin. In addition, in cases of midline diastema, the maxillary frenum may cause recurrence following orthodontic treatment, either causing aesthetic issues or diminishing orthodontic results. The treatment of such an abnormal frenum can be accomplished through a frenectomy. A case series and a review of frenectomy are presented in this article.
