Tongue tie trimming surgery for a short tongue tie is usually recommended when the child is about three years old. Tongue tie trimming surgery is recommended when the child is about three years old. Surgery done too young has a high likelihood of scar tissue formation, so it is recommended that the surgery be done when the child has some basic communication skills around the age of three. Short tongue tie may be related to X-chromosome inheritance, and there are often no obvious symptoms. The child’s tongue sticks out of the oral cavity in a short portion, and when the tongue is stretched out in front of the tongue, the short tongue tie pulls the tip of the tongue and makes the tip of the tongue in the shape of a “W”, which may result in difficulties in breastfeeding, abnormal pronunciation and other conditions. Surgery is the mainstay of treatment, but not all children need surgery, and some will improve on their own as they grow older and their tongue tie loosens.
