What tissue connects the tongue to the floor of the mouth?

The tissue that connects the tongue to the floor of the mouth is the lingual frenum. This structure is a thin band of tissue that extends from the underside of the tongue to the floor of the mouth, playing a critical role in tongue mobility. Proper function of the lingual frenum is essential for various activities such as speech and swallowing. The anatomy of the oral cavity includes various frenula, however, the lingual frenum specifically serves this unique function, distinguishing it from the labial frenum, which connects the lips to the gums, and other tissue types that do not serve this specific connection. Understanding the role of the lingual frenum is important in dentistry, particularly for procedures involving the tongue and the floor of the mouth.
