frenum (frÄÂ´num), n a vertical band of oral mucosa that attaches the cheeks and lips to the alveolar mucosa of the mandibular and maxillary arches, limiting the motions of the lips and cheeks. Older term:frenulum. Frenum.
The lingual frenulum, also known as the frenum, connects the floor of the mouth to the tongue. Ankyloglossia occurs when the frenulum is thick and severely limits movement of the tongue. In such cases, a frenectomy may be necessary to release the tongue. There are multiple salivary glands within the mouth, especially along the mouth floor. Failure of the glands to produce saliva results in xerostomia and can be caused by medical conditions or drugs.
