1, healthy teeth should be how? Healthy teeth generally meet these standards: first, no caries, periodontal disease and other oral diseases; second, the appearance of the teeth, color and lustre is normal; third, the teeth are aligned; fourth, the upper and lower teeth of the occlusal relationship is normal, in line with these conditions can be considered healthy and beautiful teeth. 2.What are the malocclusions that need to be corrected? All malformations that affect aesthetics and function should be corrected. The most common are misaligned teeth, and some abnormalities of the bite, for example, the commonly known as the lower pocket teeth, also known as the circumference of the sky, and buck teeth, these are all bite problems. There are some other special circumstances, you can go to the hospital for examination, by the doctor to determine whether the need for orthodontic treatment. 3.What are the causes of misaligned teeth? There are two main reasons for teeth misalignment, on the one hand, it is genetic factors, parents or immediate family members have teeth misalignment or bad bite, the children are also prone to similar problems; on the other hand, it is the influence of the acquired environment, for example, the milk teeth are not well protected, prematurely fall off, and there are some bad habits, such as biting the lips, sip the finger and so on, will lead to misalignment of the teeth. 4, what are the dangers of misaligned teeth? The harm of misaligned teeth is first of all on the aesthetic impact, some children will not look good because of the teeth and make self-confidence frustrated; second is the functional impact, there are some serious teeth or bad bite will affect the patient’s function of chewing, thus affecting the human body on the digestion and absorption of food. There are some cases of misaligned teeth will also affect the self-cleaning function of the teeth, the teeth themselves have a self-cleaning effect, healthy teeth in chewing food on the surface of the teeth have a cleaning effect. Teeth are not aligned will also affect brushing, brushing a lot of places can not brush, easy to cause gingivitis, the development of the periodontitis may be, but also easy to produce caries. In addition, there are some bite abnormalities will affect the health of the temporomandibular joint. 5.What are the methods of correcting irregular teeth? Correcting irregular teeth is mainly carried out by doctors through the use of various kinds of orthodontic appliances to carry out treatment, orthodontic appliances can be roughly divided into three categories: movable orthodontic appliances, functional orthodontic appliances and fixed orthodontic appliances. The fixed orthodontic appliances, commonly known as “steel braces”, are more commonly used in the clinic, and about eighty to ninety percent of the patients are treated with fixed orthodontic appliances. Fixed orthodontic appliances are basically suitable for all types of malocclusion, and the effect is also better. 6.Does orthodontic treatment require tooth extraction? About fifty percent of patients need to have their teeth extracted during orthodontic treatment. Teeth are grown in the upper and lower jaws, and the size of the jaws determines whether the teeth are lined up properly. Modern people eat very fine food and don’t need to chew very much, so their jaws have slowly deteriorated, but the number and size of their teeth have remained almost unchanged. With so many teeth lined up in a relatively small jawbone, all kinds of malocclusion can occur, so malocclusion is very common in modern people, and the treatment requires a reduction in the number of teeth to fit the smaller jawbone. The purpose of tooth extraction is mainly three aspects: first, the misaligned teeth line up the need for clearance, if it is a serious crowding of the teeth, you need to reduce the number of teeth, so that the teeth line up; second, to improve the patient’s face, such as buck teeth patients, you need to be corrected by extracting the teeth; third, to adjust the occlusal relationship, the teeth of the bad bite sometimes need to be taken to correct the method of extracting the teeth. 7.How long does it take to treat with fixed braces? Li Song: Orthodontic treatment can be roughly divided into two phases: treatment period and maintenance period. The treatment period is about two years, in these two years, you need to wear fixed braces, an average of four to six weeks need to go to the hospital for follow-up once, by the doctor to adjust the braces. After two years, when the teeth are aligned, the doctor will remove the fixed aligners, but the treatment is not completely finished. The next step is the retention period, when the doctor removes the braces and puts a retainer on the patient to consolidate the effect of the treatment. The retainer can be removed and worn by the patient himself, but it is usually necessary to wear the retainer for more than two years. For the first six months, it is recommended to wear the retainer every day and night if possible, except for taking it off during meals. After six months, wear them every night, and after one year, wear them every other night, and gradually extend the interval of not wearing them, only through more than two years of maintenance can consolidate the effect of treatment, the whole treatment is considered to be basically completed. 8.What problems should be paid attention to in the normal life of wearing fixed braces? Li Song: mainly three aspects of the problem: First, the first week of wearing braces, teeth will have pain and discomfort, when biting things, teeth will have some soreness, this pain is more obvious in the first three or four days of just wearing braces, and will gradually ease, generally one week after the disappearance of the symptoms. Afterwards, come to the hospital for review every four to six weeks, after the doctor adds force, there may also be some reaction on the same day; Secondly, pay attention to your diet, you can’t bite food that is too hard, such as bones, biting these especially hard foods is easy to damage the aligners, and this will have an effect on the treatment, you should try to avoid eating food that is too hard and sticky; don’t take the incisors to gnaw on things during the treatment phase, and when you eat apples and other fruits, you can cut the When eating apples and other fruits, you can cut apples into small pieces and bite them with your back teeth; Third, brush your teeth well. After wearing braces, oral hygiene maintenance is very important, if you do not pay attention, food debris will remain around the braces as well as in the teeth, not timely cleaning, it is easy to get caries, gingivitis and so on. It is recommended to brush your teeth in time after each meal, and try not to drink or drink less carbonated beverages. In addition, the method of brushing teeth after wearing braces is not quite the same as usual, the method of brushing teeth without braces is to brush vertically along the long axis of the teeth, and after wearing braces, you can’t brush vertically, and then you have to use a toothbrush with a smaller brush head and softer bristles to clean the surface of the teeth around the braces, and brush a little bit more carefully. Toothbrushes should be changed frequently, and it is best to change a toothbrush in one or two months during the orthodontic period. 9. When is the best time to straighten my child’s misaligned teeth? The best age for children to be corrected is ten to fourteen years old, but there are some cases that should be corrected in advance, for example, if a child is found to have “periosteum” during the period of his milk teeth, he can go to the hospital for checkups at the age of four or five years old and be treated for it. There are other cases, such as the child has bad habits, resulting in crooked teeth, which should be treated as soon as they are detected. Parents are advised to bring their children to the hospital for regular dental checkups to detect problems as early as possible. 10.Can adults with misaligned teeth undergo orthodontic treatment? From the current technology, there is no age limit for orthodontic treatment, as long as the oral conditions allow, it can be done. However, the situation of adult orthodontic treatment is a bit more complicated than that of children, because there may be caries, periodontal disease, missing teeth and other conditions in the adult’s mouth. The course of orthodontic treatment for adults is a little longer than for children. Adult orthodontics, the doctor will do a checkup first to see if he has other problems, such as caries, periodontal disease, etc., and usually recommend that he go for treatment before orthodontics. 11. Can malocclusion be prevented? There is basically no way to prevent malocclusion caused by genetic factors, but there are some malocclusions that can be prevented. When the child is very young, parents should pay attention to protecting his milk teeth and teach the child to brush his teeth during the period of milk teeth. Because the premature loss of milk teeth will have an impact on the child’s permanent teeth in the future, it is important to pay attention to the maintenance of dental health from an early age. Secondly, we should pay attention to correct some bad habits of children with teeth, such as lip biting, finger biting, once found to be corrected early, which can also prevent the occurrence of some malocclusion. Parents in the preparation of food for children, you can prepare some chewy food, do not have to make the food particularly fine, do not need to chew to swallow, because appropriate chewing to stimulate the development of the jawbone is good, but also can avoid the occurrence of malocclusion.
