The best time to operate on a short tongue tie in infants is around one year of age.
The tongue tie is an elastic fascial tissue that connects the tongue to the floor of the mouth, and mainly serves to fix and control the movement of the tongue. If the tongue tie is too short, i.e., the tip of the tongue is in a W-shape when the tongue is stretched out or the tongue is not able to be lifted up normally, tongue lengthening will be needed to restore the normal movement of the tongue.
Babies are usually born with a short tongue tie, but as they grow older the tongue tie will gradually return to normal; however, if the tongue tie is still short when the baby starts to speak at the age of one, it is necessary to consult a doctor for tongue lengthening surgery to restore the normal movement of the tongue tip to prevent the child from affecting his/her normal pronunciation in the future.
