The old saying “smile without teeth”, however, in modern times, a smile without teeth is often a symbol of lack of confidence. In some European and American films, we can often see foreign movie stars show a confident and full smile, which is inseparable from their white, healthy teeth. In Western countries, orthodontic treatment for children during the period of dentition is a common behavior, after this treatment, children in adulthood, not only the teeth are particularly neat and beautiful, the whole facial development is also more coordinated and beautiful, which plays a vital role for the child to society after adulthood. In recent years in China, with the increasing awareness of oral health, we are also paying more and more attention to oral health, and more and more families are having orthodontic treatment for their children, but many people still have fears or doubts about orthodontics. Today, let us approach orthodontics and decipher several misconceptions in the orthodontic process. 1, there is no problem why the teeth should be pulled? In the process of human evolution, as food becomes cooked and soft from raw, the chewing function gradually weakens, resulting in the degeneration of the mouth and jaw organs. In this regard, the jawbone degenerates faster than the teeth, resulting in more teeth than bone, resulting in crowded and uneven teeth, which makes more and more patients need to have their teeth extracted for orthodontic treatment. Many parents do not understand and worry that tooth extraction will affect their children’s brain and body development, and some parents may ask what to do with such a large gap after tooth extraction, and do they need to set teeth? In fact, these worries are unnecessary, as orthodontic treatment can align and level the teeth, establish a normal bite, and restore the patient’s chewing function. In some cases of bimaxillary protrusion of buck teeth, orthodontic extraction is the only way to improve the facial shape and achieve overall facial harmony and beauty. In fact, the clinician will make a comprehensive analysis and consideration of the patient’s dentition and jawbone before making the orthodontic plan for tooth extraction, and use a personalized treatment design plan to achieve the most perfect orthodontic effect. 2, orthodontics is only for teenage children? When it comes to orthodontics, many people may think that only children can do it. In fact, orthodontics is age-neutral, as long as the patient’s periodontal tissue is healthy, orthodontics can be performed at any age. Dr. Chen explained that orthodontics is the process of applying the appropriate “biological force” to the teeth, alveolar bone and jawbone to cause physiological movement and alteration. The best time for orthodontics is not absolute, but depends on the type of malocclusion and the growth and development of the individual. Generally speaking, if the teeth are simply misaligned and the facial development is normal, before the age of 11-14 is considered the best age for orthodontics, which is short and effective. Adults can be orthodontic, the effect is the same, but because adult growth and development has stopped, bone metabolism and alveolar bone reconstruction is relatively slow, the teeth move relatively slow, the orthodontic time required is relatively long. 3, wearing braces is very uncomfortable, no way to eat? Some parents say, wearing braces children can not eat, nutrition will not be able to keep up with it? In the orthodontic process, the teeth are subjected to physiological optimal orthodontic force, the alveolar bone will produce active alterations, the teeth move faster, the alveolar bone will follow the teeth to move the alterations, after the orthodontic treatment, the healthy and plump alveolar bone will ensure the stability of the orthodontic results, the pain is reduced or disappeared or the time is shortened after the force is added. There are individual differences in discomfort during the orthodontic process, but most patients feel only slight soreness for a few days after each follow-up visit, and some patients do not experience pain throughout the orthodontic process. With the introduction of self-ligating brackets, the pain response is greatly reduced in some cases of severe crowding due to less friction during the movement of the teeth. The orthodontist asks the patient not to bite hard objects, mainly based on the consideration of protecting the brackets from falling off, rather than the inability of the teeth to bite, in fact, the orthodontic process of normal eating meat, fish and shrimp is no problem at all. Some children have poor chewing efficiency due to poor bite function, resulting in delayed physical development, and orthodontic treatment is not only for aesthetics, but also for health.
