At present, many students have malocclusion of the mouth, and at least 70% of the children need orthodontic treatment, but parents and students have many misunderstandings about orthodontic treatment. What should I pay attention to in my child’s teeth straightening? It is not necessary to wait until the age of 12 for the child’s orthodontic treatment. Many parents believe that when the child has changed the deciduous teeth, the permanent teeth will come out, especially after the age of 12 is the best period for orthodontic treatment. This statement is not entirely correct. If it is generalized, it will often make many people miss the best time for orthodontic treatment and increase the difficulty of orthodontic treatment. When there are problems in the mouth of children, such as the ground and the sky, they cannot wait until the age of 12 to deal with them. Because of the poor growth environment, it may deteriorate with age, and it is very difficult to deal with the teeth straightening after the upper and lower jaws are shaped. Besides, it is likely to have a negative impact on the child’s psychology, so orthodontic treatment should be carried out as soon as possible. Children’s orthodontics should pay attention to not necessarily need to extract teeth. Fear of tooth extraction is also a relatively common phenomenon in clinical practice. As soon as parents hear that they are going to extract their children’s teeth, they immediately stop thinking about orthodontic treatment. In fact, doctors will adhere to the principle of not pulling teeth as much as possible to formulate orthodontic programs. If there is a slight crowding of the teeth, or there is a gap, there is no need to extract the teeth. However, since most patients require orthodontics because of crowded or protruding dentition, extractions can create space for crowded or adducted teeth. This is like only 10 people can stand on a road. Due to the reduction of venues or the increase of people, and the requirement to queue up neatly, the number of people can only be reduced. But let everyone rest assured that all the gaps in the extraction will be gradually closed during the orthodontic process, and there is no need for subsequent dental implants. Attention should be paid to children’s orthodontic treatment. Some people put on braces and say, “If I knew it would be so painful, I wouldn’t do it.” Others said, “Why don’t you feel it? Is it because the doctor didn’t do it well?” Braces?” Everyone feels differently after wearing braces. After wearing braces, there may be discomfort, such as pain, swelling, discomfort of biting, etc., and these feelings mostly appear during the first orthodontic treatment. The most uncomfortable is the first three days, and after wearing it for a long time, I will gradually get used to it. So far, there has been no case of requiring removal of the braces due to pain after wearing them.
