Guidance: Hello, avoid eating hard food such as bone food, and avoid eating large pieces of food. Avoid eating the above foods to make them bigger and smaller, which can prevent the attachment of the appliance from loosening due to improper diet. It is suggested that the apples and pears after dental plastic surgery be cut into small pieces before eating hard foods such as ice cubes, nuts, hard biscuits, sugar cane, hard candy, crabs and lobster shells.
