Hello, this condition is not terrible. Orthodontic process: comprehensive oral examination model, X-ray photos, orthodontic design, tooth extraction or not, orthodontic treatment, orthognathic surgery for severe jaw retention and bone deformity in maintenance stage. The oral condition before malocclusion treatment varies from patient to patient, and the time of orthodontic treatment is not exactly the same. Patients with this disease can't smoke, drink or eat spicy food, and their diet should be light and nutritious as far as possible, so as to exercise and maintain physical and mental health.
