Tongue tie, medically known as ankyloglossia, is a relatively common condition present at birth – it’s estimated that approximately 10% of babies are born with a tongue tie. It is often more common in boys and can be genetic.
The strip of tissue, or lingual frenulum, that connects the tip of the tongue to the bottom of the mouth usually detaches before birth, but if it fails to do so, then it can restrict the tongues normal range of movement. Sometimes tongue tie might not cause complications, but, in many cases, it can make it harder for the baby to feed, particularly with breastfeeding. This is often the first indication.
It can increase the risk of tooth decay or cause speech difficulties in later life. Tongue ties can be categorised as anterior, which means at the front of the tongue, or posterior is further back under the tongue.
