The current mainstream view is that the best age to cut the tongue tie in children is after the child is 4 years old, because the tongue tie itself, also known as the tongue tie, has a gradual backward process during the child’s growth and development. Sometimes the tongue tie, which looks significantly shorter in infancy, will gradually become normal as the child grows and develops. It also does not affect the child’s pronunciation, so it is not necessary to have the tongue tie done that early. Generally, after the age of 4, when the child’s intelligence, speech center and hearing have all developed to a better state, and the child’s tongue tie is still found to be short, then surgery can be considered. Of course, there is some controversy regarding the timing of tongue tie surgery. Some people suggest that tongue tie surgery should be performed between the ages of 1 and 2 years old. This is mainly because children’s speech is gradually formed between the ages of 1 and 3 or 4 years old. Both arguments have some merit. Clinically, it is not recommended that children undergo lingual ligament surgery at the age of 1 year, because premature surgery can easily lead to scar formation of the corresponding lingual ligament, sometimes requiring secondary surgery.
