There is a joke: An American Chinese teacher, in order to make the Chinese children understand what is the meaning of the crow returns the favor, said, for example, your parents pay for your braces when you are small, and when you grow up you make dentures for your parents, please use an idiom to summarize this phenomenon, one child immediately answered: return the favor with a tooth. The joke is a joke, but it shows the prevalence of orthodontic treatment in the United States. Under China’s family planning policy, parents devote all their care to their only child, but often there are misunderstandings about orthodontic treatment that delay the treatment of their children. Orthodontic treatment is commonly understood as wearing braces to align the misaligned teeth, many parents think that this is just for the sake of beauty, but in fact it is not true, the two major diseases of dentistry, dental caries and periodontal disease are caused by poor oral hygiene, there are many factors that affect oral hygiene, among which teeth misalignment is a very important factor, many parents think that as long as you brush your teeth well to maintain good oral hygiene, but in fact it is not. Many parents think that if they brush their teeth well, they can maintain good oral hygiene, but this is not true. Misaligned teeth will leave a dead space for cleaning, an area that cannot be reached by a toothbrush, and even if they brush their teeth very carefully, it is difficult to remove the plaque. Of course, another effect of orthodontic treatment is aesthetics, the impact of the ground is self-evident, on the contrary, if the teeth are too prominent, the impact on the facial aesthetics is also great, orthodontic treatment in changing the position of the incisors for the facial aesthetic improvement is very obvious. There was a patient, a master’s student, who told me at the first consultation that she was a very hardworking and studious child with a slightly introverted personality, but her relationship with her supervisor was very tense and she was very distressed, and after side understanding she realized that her supervisor was not satisfied with her because when talking to my patient, my patient always pouted and looked like she had a great opinion of her supervisor. In fact, she did not have a problem with her tutor, but her lips could not be closed because her incisors were too prominent, so she wanted to improve her appearance through orthodontic treatment. After a period of treatment, her incisors were retracted and her face was not protruding. Through communication with her tutor, misunderstandings were eliminated and her relationship with him improved greatly, and her personality was much more cheerful. The advantages of early treatment for children are that children are in the growth and development stage, with active physiological alterations, good treatment results and faster tooth movement than adults, and children are still in the school learning stage, unlike adults who have a lot of social activities, conventional lip-side orthodontic treatment has limited impact on appearance. Children’s nervous system is in the developmental stage, so they are better able to adapt to the discomfort that orthodontic treatment may cause than adults. Since orthodontic treatment is a physiological movement of the teeth, with the movement of the teeth the bone is subsequently altered and the teeth are not loosened under regular treatment, which is a concern for many parents. Orthodontic treatment usually begins early in the permanent dentition, around the age of 12. One point worth stating is that for children with skeletal deformities such as geodontia and overly protruding upper jaw, early orthodontic treatment is needed, and a professional orthodontist needs to be consulted as to whether or not orthodontic treatment is needed, so as not to miss the best treatment period. Children are the expectation of their parents, and it is necessary for parents to know more professional knowledge to raise their next generation scientifically and correctly.
