A baby with a short tongue ligament should be examined by pediatric dentistry or oral and maxillofacial surgery. The lingual ligament is a thin strip of tissue woven between the tongue and the floor of the mouth when the tongue is opened and pried up. When the lingual ligament is of normal length, the tongue can move freely and can naturally stick out of the mouth or touch the upper gums. A short tongue tie can interfere with breastfeeding or rub against the lower front teeth and cause ulcers. The baby’s tongue cannot move up properly when opening the mouth, cannot lick the upper gums or cannot reach past the upper lip, which can affect the baby’s normal pronunciation. Babies with short tongue ties have less room to move their tongues, which can hinder normal chewing and cause slow chewing or more swallowing during meals. When you suspect that your child has a short tongue tie, you can check whether the tongue tip is depressed when you spit it out, and whether the forward extension of the tongue and the upward lift of the tongue tip against the gingival palate can be completed. If the tongue does not move properly, the child should be examined in the hospital to determine if there is a short tongue tie problem. If it is determined that the child has a short tongue tie, surgical treatment can be given, and after the surgery is completed, the child’s speech training and tongue-arrowing against the palate training should be reinforced.
