We need to pay attention to many things during orthodontics, the most important of which is diet. A little carelessness will affect the orthodontic effect, so what can't be eaten in orthodontic treatment? Let's introduce it to everyone. During orthodontics, the teeth of beauty seekers are still very sensitive. At this time, you should be extra careful in your diet, so as not to affect the health of your teeth and mouth, but also to absorb nutrients properly. In the meantime, as long as you don't eat too hard and sticky food, such as pine nuts, chewing gum and bubble gum. In addition, when eating, try not to chew with your front teeth. You can chop up the food with a knife before eating. During orthodontics, you should eat less of the following foods: 1, hard foods, such as ice cubes, nuts, hard biscuits, sugar cane, hard candy, crabs, lobster shells, etc. I also quit bad habits such as biting my pen and nails. 2, too sticky food, such as toffee, maltose and some biscuits and other foods, chewing gum should chew sugar-free ingredients. 3. Too big food, such as apples and pears, should be cut into small pieces before eating. Diet during orthodontics is also related to oral health after orthodontics, because many people will have periodontal diseases such as gingivitis during orthodontics. Eating fruits and vegetables rich in vitamins at this time can accelerate the recovery of periodontal disease and consolidate dental health. However, it should be noted that it is best not to eat irritating foods, such as foods that are too sour, too hot, too cold and too spicy. Of course, in order to avoid dental caries, try to eat less sweets during orthodontics, and bone metabolism increases during tooth movement, so we should pay attention to calcium intake. In addition, looking for a regular hospital for orthodontics, I believe the doctor will also tell you this to make your orthodontics better.
