What is
Tongue Tie?
Tongue-tie, or ankyloglossia, refers to an abnormally tight "sublingual frenum."
A tongue-tie is a piece of tissue under the tongue that connects it to the floor of the mouth. This piece of tissue is called a frenum, and everyone has one. In some people, it’s tighter than it should be, and this is where all the problems come in.
It occurs during pregnancy when a small portion of tissue that should disappear during the infant’s development remains at the bottom of the tongue, restricting its movement.
