Hello, this condition is not terrible. After plastic surgery, you should not only follow the doctor's advice, but also take good care of the braces on your teeth. First of all, we should avoid eating hard food, such as bone food, crabs, nuts and so on. It is also necessary to avoid eating large pieces of food, such as cutting apples into small pieces to prevent the attachment of the appliance from loosening due to improper diet, so that the whole correction process can be successfully completed. 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.
