<unk> , commonly known as tongue tie, is a congenital oral anomaly which may decrease mobility of the tongue tip.<unk>  is caused by an unusually short, thick lingual frenulum, a membrane connecting the underside of the tongue to the floor of the mouth.<unk>  varies in degree of severity from mild cases characterized by mucous membrane bands to complete<unk>  whereby the tongue is tethered to the floor of the mouth.<unk>  can have feeding, speech and mechanical/social effects as well as result in other problems such as an open bite and mandibular prognathism. There is professional disagreement regarding how often<unk>  is symptomatic. In addition, intervention is also controversial as researchers such as Horton et al. believe that people with<unk>  can compensate in their speech for limited tongue range of motion and do not require surgery.
