1.Why do I need to extract healthy teeth for orthodontic treatment? Does the extraction of teeth have any effect on health? A: With the evolution of human beings, the jawbone degenerates earlier than the teeth, and the size of the jawbone becomes smaller and smaller while the number and size of teeth do not change accordingly, so the phenomenon of crowded teeth or “whistling teeth” appears. This is like standing in line, because of the limited space, if everyone is standing side by side, there is no room for everyone, and only some people can fit everyone by turning their bodies sideways or crooked. In order to get the teeth aligned and have a good bite relationship between the upper and lower teeth, it requires us to remove a few unimportant teeth to provide space and use that space to line up the important teeth. In the orthodontic treatment, we choose the least functional role or try to choose rotten teeth to extract when there are rotten teeth, and the extracted teeth have no effect on the whole oral health. 2.What about the big gap after tooth extraction? A: To correct the gap after tooth extraction is to provide space for the alignment of teeth and restore the normal angle of teeth, after correction all the gaps will be closed, there will not be any gaps left. 3, orthodontic teeth after the teeth will not be loose, eating will be affected, people will lose teeth when they get old? A: Orthodontics is a physiological process of moving teeth, teeth grow on the alveolar bone, the alveolar bone has elasticity and plasticity, when we apply force to the teeth to move the teeth alveolar bone alteration, to put it simply is the teeth with the alveolar bone with the movement, the alveolar bone alteration takes a certain amount of time, so in the process of orthodontics need a month interval and then review, mainly to the alveolar bone The main purpose is to provide time for the alveolar bone to be rebuilt. The teeth will be stabilized in their new position after moving to the new position, and orthodontic treatment will not lead to tooth loss at an older age. Only when irregular orthodontic treatment or periodontal disease occurs will teeth become loose or even fall out. Patients who need orthodontic treatment are advised to choose a dental specialist hospital and a professionally qualified doctor for treatment. In addition, the incidence of periodontal disease is very high, so whether you orthodontic teeth should be regular oral examination, timely detection of the causes of periodontal disease such as tartar, tartar, etc., to prevent the emergence of periodontal disease leading to tooth loosening. So the regular orthodontic will not lead to loose teeth fall off. 4, orthodontic teeth take about 2 years, too long, can not be faster? A: As mentioned before, it takes time to reshape and regenerate the alveolar bone after the teeth are moved, and moving the teeth too quickly will affect the reconstruction of the alveolar bone, which has a certain impact on the stability of the treatment effect. People often say that patience to keep the loneliness to keep the prosperity, orthodontics is also the same, the rush will be contrary to the wishes, so please orthodontic friends must be patient Oh! 5, orthodontic teeth on daily life has no impact? A: Orthodontic patients just put on the braces after 3 to 5 days will feel the teeth sore and soft, weakness to eat, which is the initial adaptation phase of normal reaction. After the adaptation period can be completely normal diet, normal meals and meat can be eaten. Of course, there is no restriction on the taste of food (sweet, sour, salty and spicy), in short, you can eat normally. 6.Why is the cost of orthodontics so high? A: Orthodontics is an ongoing process and requires a monthly follow-up. Orthodontic fees are usually the cost of the total course of treatment, that is, about 2 years of all the treatment costs, if converted into the cost of each follow-up visit is actually not high. 7, orthodontics must be strictly in accordance with the follow-up time? What if I can’t make a follow-up appointment on time? A: Usually, orthodontic follow-up once a month, the appointment can be adjusted around the time, it does not have to be exactly 30 days. It is not a big problem if it is 7 days earlier or later.
