Hello, take care of the appliance on your teeth after plastic surgery. You should avoid eating hard food, such as bone food, and avoid eating large pieces of food, so as to prevent the attachment of the appliance from loosening due to improper diet. Also pay attention to eating less sticky foods such as chewing gum, eating less sweets and paying attention to calcium intake. Pay attention to brushing your teeth in the morning and evening. It's best to choose a soft toothbrush and don't eat irritating food, such as food that is too sour, too hot, too cold and too spicy.
