Tongue-tie which is also known as Ankyloglossia , is a congenital anomaly characterized by an abnormally short lingual frenulum which may restrict mobility of the tongue tip.

The phenotype varies from absence of clinical significance to rare complete ankyloglossia where the ventral part of the tongue is fused to the floor of the mouth.

The abnormally short lingual frenulum may result varying degree of decreased tongue mobility.

Tongue-tie (Ankyloglossia) has been suggested to cause breast-feeding difficulties (sore nipples, poor infant weight gain, early weaning), speech disorders (impaired articulation), problems with deglutition and dentition, oral-motor dysfunction and social issues related to the limited function of the tongue.
