An Insight into the Frenum

The frenum is a fold of mucous membrane connecting the lips and cheeks to the gingiva periosteum and alveolar mucosa. It often contains muscle fibers. The maxillary labial frenum mandibular labial frenum and lingual frenum are the three most often seen frenum that are typically present in the oral cavity. Their main function is to stabilize the tongue upper lip and lower lip. The mucogingival junction and alveolar mucosa involved in the frenum are said to be structurally identical to those in any other area. The limited information on frenum per se and its clinical implications has not been adequately dealt with in the literature. Hence an attempt was made to present them in this review.
