What should babies pay attention to when their parents have “bruxism”? Some parents who have “bruxism” themselves find it unsightly to have their teeth jutting out in front of them, so they worry that their children will grow up with “bruxism” like they do. What do babies and parents need to pay attention to? As the saying goes, “You reap what you sow, and you reap what you sow”, babies’ features always look like their parents’, and of course, teeth and face shape are no exception. Although the heritability of “bruxism” is not as high as that of “geodontia”, there is still a certain genetic tendency. The term “malocclusion” is a common name for Class II malocclusion, which can be divided into two categories: dental and bony malocclusion. Dental malocclusion refers to normal facial bones and is simply caused by the protrusion of the teeth. For this type of child, orthodontics can be done only after tooth replacement is completed, and there is no age limit for orthodontics, which can be done from adolescence to adulthood. As the name implies, osseous malocclusion refers to the “protruding teeth” caused by abnormal development of the facial jaws, which are generally inherited from the parents. It is often thought to be caused by maxillary protrusion, but in fact, not only maxillary protrusion can cause malocclusion, but also mandibular (jaw) recession is an important cause of malocclusion, or both. Patients with simple maxillary protrusion show a prominent middle face, protrusion of the upper front teeth, and a basically normal lower jaw; patients with simple jaw recession have an obvious receding lower jaw in the side view, and the chin muscles are tense while the lower part of the face is not high enough; when the maxillary protrusion and the receding lower jaw coexist, they often show a prominent middle face and a receding lower jaw, an open lip, and an outward turning lip. Regardless of which of the above three cases, as long as the child has a bony problem (that is, the parents are buck teeth), parents should pay sufficient attention to it and go to the hospital for treatment as soon as possible once it is found. Usually the best time for treatment is before the child’s height begins to grow rapidly, that is, before the rapid development of puberty, and treatment can usually begin when the upper and lower incisors are replaced, because at this time children’s bone tissue is highly plastic and can be treated through orthopedic treatment. When the first menstruation of girls, boys become vocal, there is no way to correct, only through the surgical solution.
