Recently, as a medical officer, I participated in the medical examination for the college entrance examination and the medical examination for military recruitment. During the physical examinations, I found a problem: many children’s tongues looked shorter than other children’s, which was due to the tethering problem. Some people ask: Is pronunciation necessarily affected in people with short tongue ties or not? Research shows that there are many factors that affect pronunciation, such as: intelligence, psychological and personality factors, hearing factors, mouth and nasal structure, pronunciation methods, pronunciation habits, cognitive ability and so on. The tongue tie can affect only a small part of it. When I was working in the clinic, I often met young parents who came to consult with their newborn children, saying that they suspected that their children’s tongue tie was too short; there were also parents who brought their two- or three-year-old children to the clinic and asked to check whether the tongue tie was normal. Here, I would like to tell parents some facts: 0-6 months old babies’ milk teeth have not yet erupted and the tongue tie attachment point is forward. The “short tongue tie” that some infants exhibit is a temporary physiological phenomenon and should not be a cause for concern. It is normal for school-age children in the phonological learning stage to have some problems with their pronunciation. If the child can pronounce normally through normal speech training, there is no need to rush to surgery. After the age of 6, the position of the tongue tie is basically stable, so the child can be conservatively observed during this period. If you suspect that your child has pronunciation problems, you can go to a professional speech therapy institution for evaluation and examination, with speech training as the main focus. The result of the combination of multiple factors is unclear pronunciation. The short tongue tie alone may cause slurred speech, but it is often not the main factor. A correct pronunciation method and good pronunciation habits are especially important. However, if the child has the following conditions, he or she still needs to seek medical treatment: 1, affects breastfeeding or swallowing (newborns, infants and children); 2, often rubs against the lower front teeth and has repeated ulcers; 3, pronunciation disorder, after formal voice training, the phonetician thinks that the tongue tie is too short really affects pronunciation, and simple voice training is not effective. 4, of course, the tongue tie is too short in addition to the pronunciation of the impact, but also may cause some other problems, also need parents to understand and attention
