The optimal time for surgery for a short upper lip tie is around 10 years of age, but this varies between individuals, so it is advisable to seek medical attention for a definitive diagnosis and surgical treatment. The upper lip tie is short and thick at birth, but it will gradually recede to a normal level as we grow older; on the contrary, it will cause the upper incisors to attach too low to each other, resulting in a wide gap between the upper incisors. Therefore, it is recommended to seek medical advice for lengthening of the upper lip tether, which is usually recommended to be performed around the age of 10 years, as the success rate of the surgery is too high; the surgery is usually performed under local anesthesia, and after successful anesthesia, scissors or scalpel are used to cut open the short tether and then suture the incision closed.
