What is Tongue Tie or restricted lingual frenulum (RLF) ?
Tongue tie also known as ankyloglossia is a condition in which a persons tongue remains attached to the floor of the mouth. This occurs when the lingual frenulum (a thin strip of tissue connecting your tongue and the floor of your mouth) is shorter than usual. A short frenulum can restrict your tongues movement. Ankyloglossia is most common in new-borns, and young children. Most commonly associated with breastfeeding difficulties and also believed to have some impact on speech and / or oral hygiene problems. The true impact of tongue tie on speech isn’t clearly understood. More research is needed. However, the child’s tongue needs contact with the roof of the mouth when pronouncing the lingual sounds “I” “d” “z” “s” “th” “n” and “t”. when the tongue is severely restricted and cannot reach the roof of the mouth, the child could have problems with articulation of these sounds.
Do all babies have a tongue tie?
Anyone can develop a tongue tie. Tongue tie is congenital, which means people are born with it. If one of your babies have a tongue tie, then its likely the others will too. Ankyloglossia occurs in up to 10% of newborns.
