Every summer is the peak season for orthodontic treatment. For first-time orthodontic patients, especially the student population, the following matters should be understood in advance: 1, orthodontic treatment before the need to take pictures to understand the patient’s teeth and bone. 2, orthodontic treatment may require tooth extraction, so that the teeth are aligned neatly. 3, follow the time requirements of the doctor, regular follow-up. 4, try to avoid eating too hard things during orthodontic treatment. However, normal meals, vegetables and meat are consumed normally.
