A short tongue tie is medically known as a short tongue ligament and can affect a child’s speech. It is recommended that surgery be performed as early as possible, usually around 12 months of age. A short tongue tie is a mucosal fold that continues between the underside of the tongue and the mucosa of the floor of the mouth, called the lingual ligament. If there is a short lingual ligament, tongue extension will be limited or the tip of the tongue will be stretched where it touches the hard palate of the upper chamber, and the pronunciation of apical sounds will be affected, which may result in unclear spitting. The earlier the surgery is done, the better, because it is important to do the tongue ligature surgery as early as possible when the child is learning to speak and form the language. The surgery is also very simple: the tongue tie is cut open and reoriented, and then a certain amount of molding is done. If the child is older and has developed bad pronunciation habits, speech correction training is needed after the surgery. Under the guidance of a professional doctor, speech training and tongue movement training can be strengthened on a daily basis.
