Frenum is a mucous membrane fold consisting of mucosa, connective tissue fibers and muscle fibers which attaches the cheek and lips to alveolar mucosa. Aberrant frenum is of great clinical significance as it may cause problems like gingival recession which may be due to muscle pull or inadequate plaque control measures. Gingival recession may lead to dentinal hypersensitivity and increases the risk of root caries. Frenal attachments have been classified according to the position of attachment of frenum. Various frenectomy and frenotomy techniques have been used for the management of aberrant frenum. Aberrant labial or lingual frenum has been more frequently reported as compared to aberrant buccal frenum. The present case reports management of abberant buccal frenum in all the four quadrants causing gingival recession and dentinal hypersensitivity.
