Hello, considering the situation you mentioned, many orthodontists need to extract teeth before wearing orthodontic appliances, and some need to fill and clean their teeth. Go to a regular hospital for regular treatment. Don't grind your teeth when you do orthodontics, because there is a protective film on the outside of your teeth. When you grind your teeth, you will wear off the protective film. No matter how you protect them in the future, they are prone to dental caries. After wearing braces, many people will get stuck in their teeth after meals, and it is difficult to clean up even if they gargle. You need to think it over before you correct them. Patients with this disease should not eat too much food with high calorie, avoid alcohol, tobacco and spicy and greasy food in their daily diet, pay attention to properly supplement nutrients such as protein and vitamins, and eat more fruits and vegetables.
