Buck teeth can be inherited. Buck teeth have a genetic tendency and a tendency to cluster in families, so there is a possibility that they can be passed on to the next generation. However, a parent’s buck teeth are the result of bad habits and will not be passed on to the next generation. Parents’ congenital and hereditary buck teeth are inherited from the previous generation, which means that there is a family genetic history, and the children of the next generation will also have buck teeth, which can be early intervened and treated by orthodontic means, and won’t affect the aesthetics. Parental buck teeth are the result of bad habits and are not passed on to the next generation. Usually it is finger sucking and mouth breathing that causes buck teeth. When educating the next generation of children, always pay attention to whether the children have such behavior, and intervene in time to discover and develop good habits. Nowadays, children may also suffer from jawbone underdevelopment due to overly fine food, resulting in crowding of the teeth, which can be examined by an orthodontist, and under the doctor’s guidance, muscle function training can be carried out to stimulate jawbone development. It is recommended that minors should have a dental checkup every 3-6 months for early intervention or treatment of malocclusion.
