The frenulum linguae, commonly known as tongue-tie, is a fold of mucous membrane that connects the underside of the tongue to the floor of the mouth. In some cases, this frenulum can be congenitally short, which may restrict the tongue's movement. This condition is sometimes believed to cause difficulties with feeding or speaking, but medical studies indicate that a short frenulum is often a normal variation that does not impede these functions and typically requires no treatment.123
