The baby's lingual frenulum is in the developing stage. In the neonatal period, the lingual frenum extends to or near the tip of the tongue. During the development of the tongue, the lingual frenulum gradually recedes to the base of the tongue. After the normal children are 2 years old, the lingual frenulum gradually moves away from the tip of the tongue. Therefore, in infancy, the lingual frenulum is mostly tense, and the lingual frenulum may be "too short", which is a temporary physiological phenomenon, not abnormal. With the growth of age and the eruption of deciduous teeth, the lingual frenulum will gradually move under the mouth, become thinner and looser, and the mobility of the tongue will become more flexible, and the lingual frenulum will not be short.
Children after 2 years old or even older should go to the hospital for examination if the situation of too short lingual frenulum has not improved. For the sublingual mucosa that often rubs to form ulcers, or the tongue band is too short to affect pronunciation, surgery can be considered. Therefore, if you find that your baby's tongue is too short, you may wish to observe it for a while.
