Orthodontic treatment usually takes about two years to return to normal, but due to individual differences, treatment methods, and the degree of malocclusion, there will be some differences in recovery time. In general, the recovery time for children’s orthodontic treatment is shorter than that of adults, whose jaws are already fully formed, so the process of orthodontic treatment is relatively more difficult and requires a longer recovery time. The recovery time for those who do not need extraction treatment is shorter than those who need extraction treatment, and if the patient’s deformity is higher, the recovery time will be longer. Patients should pay attention to oral care during orthodontic treatment, do a good job of oral hygiene and cleanliness, avoid eating harder or hotter foods, and develop good brushing habits. In daily life, it is also necessary to wear a gap retainer as prescribed by the doctor to maintain orthodontic effect and prevent failure to achieve the expected orthodontic requirements.
