What is Tongue Tie?
The lingual frenulum (or frenum) is a remnant of tissue in the midline between the undersurface of the tongue and the floor of the mouth. When it interferes with normal tongue function it is called “symptomatic tongue-tie” or “symptomatic ankyloglossia.” Tongue-tie can adversely affect breastfeeding. Research is urgently needed to examine the impact tongue-tie and other oral restrictions may have on chewing, swallowing, regurgitation, digestion, speech, and breathing.
