Tongue-tie (ankyloglossia) is a condition present at birth 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.
Signs and symptoms of tongue-tie include Difficulty lifting the tongue to the upper teeth or moving the tongue from side to side, Trouble sticking out the tongue past the lower front teeth, a tongue that appears notched or heart shaped when stuck out
Epidemiology: The prevalence of ankyloglossia reported in the literature varies from 0.1% to 10.7%. Looking for oral mucosal findings in general, the prevalence of tongue-tie is lower (0.1% to 4.4%) than in studies.
