Therefore, you should be prepared for a “protracted war”. 2.Preparation of hard food The braces are bonded to the teeth, gnawing on hard things can easily lead to bracket loss, which increases the number of follow-up visits and prolong the treatment time. 3, cost preparation Orthodontic treatment is a cosmetic project, not covered by medical insurance. The cost of orthodontic treatment varies from city to city, and from hospital to hospital in the same city. The cost is related to the level of the hospital, the consultation environment, the instruments and equipment, the materials used, the type of malocclusion and the degree of education of the doctor. In Wuhan, the cost of orthodontic treatment in a better hospital is more than 8,000 yuan. 4.Risk preparation The presence of orthodontic appliances in the mouth makes it more difficult to brush your teeth. During the treatment period, if you fail to brush your teeth properly, it will easily lead to tooth demineralization, tooth decay and gum inflammation. Due to the influence of human growth type, some patients have recurrence of deformity after orthodontic treatment. 5.Study, work impact preparation As it is necessary to review once in about 1 month, it may affect children’s study and adults’ work; wearing orthodontic appliances may also affect the beauty of special occupations, such as: actors, teachers, etc.
