Tongue-tie (ankyloglossia) is a condition that restricts the tongue's range of motion.
With tongue-tie, an unusually short, thick or tight band of tissue (lingual frenulum) tethers the bottom of the tongue's tip to the floor of the mouth. A person who has tongue-tie might have difficulty sticking out his or her tongue. Tongue-tie can also affect the way a child eats, speaks and swallows, as well as interfere with breast-feeding.
Sometimes the lingual frenulum loosens over time and tongue-tie resolves on its own. In other cases, tongue-tie persists without causing problems.
If necessary, tongue-tie can be treated with a simple surgical procedure called a frenotomy. If additional repair is needed or the lingual frenulum is too thick for frenotomy, a more extensive procedure known as frenuloplasty might be an option.
