Hello! First of all, I wish you good health! For the sake of our fate, I will talk to you about the problem of "beating your teeth" below. Digging is a common type of tooth regularity, in which the lower teeth protrude more than 1 cm than the upper teeth. Medically called malocclusion, commonly known as "the sky is all over the ground", is a common malocclusion. Tooth picking is hereditary. 1) treatment for children with toothache, there are three treatment opportunities: 1. The first stage: occlusal period of deciduous teeth. The best orthodontic age at this stage is about four years old. At this time, the child's permanent teeth have not erupted, and the roots of deciduous teeth have not been absorbed. They can be corrected by wearing movable appliances in the mouth, and the course of treatment is about 6 months. Early treatment at this stage is of great benefit to the normal growth and development of children's maxillofacial region. 2. The second stage: occlusal period of mixed teeth. After the upper and lower four front teeth are replaced, the child can continue to correct when he is about 8 or 9 years old. According to the severity of deformity in children, movable appliance, fixed appliance and even external plastic force can be used to correct teeth. If treated in time, it will be of great help to children's face improvement and growth and development. 3. The third stage: occlusal period of permanent teeth. After the baby's deciduous teeth are completely replaced, it is about 12 years old, which is the peak of growth and development. Children who are still brushing their teeth at this time can continue their treatment. Because the growth of children's mandible is basically synchronous with the growth of their height, it is still necessary to observe the end of the peak period of children's growth and development after orthodontic treatment is completed. It should be noted that large hospitals and experienced doctors should be selected for orthodontics. 2) Preventive measures 1. In infancy, mothers should master the correct breastfeeding posture. 2. Don't let the baby lie flat and suck milk with a bottle. 3. For children who have bad habits of biting the upper jaw or stretching the lower jaw, we should intervene as soon as possible (convince people by reasoning) and get rid of bad habits as soon as possible. 4. If the front deciduous teeth should not fall off or fall off prematurely due to accidents, you should see a doctor in time, pull out the stranded deciduous teeth and keep the space between them. Love tip: If you feel unwell, it is recommended to go to the hospital for relevant examination in time so as to prescribe the right medicine. If you are satisfied with the above answer, please don't disappoint my kindness and adopt it as an answer in time.
