Winter vacation is a good time for students to correct their teeth, because orthodontics takes time at the beginning, and winter vacation is just the time to use it. At the initial stage of orthodontics, doctors need to take photos of patients, take dental casts and communicate with patients about orthodontic design and treatment process. At least the hospital will cooperate and communicate two or three times to facilitate the children not to attend classes during the winter vacation. In addition, just wearing an appliance requires an adaptation process. Choosing to do orthodontics in winter vacation can easily help children get through the adjustment period and minimize the impact of orthodontic appliances on children.
