First, there are normal parasitic bacteria in people's mouth and a large number of microorganisms in the air, so the mouth often "contacts" with the outside world. Wearing an appliance on your teeth will hinder brushing your teeth. If the teeth are not brushed well, there is food residue between the teeth, and a large number of bacteria will cause dental caries or periodontal tissue inflammation, which will destroy the whole course of treatment. Therefore, the most ideal way of dental care is of course to brush your teeth after every meal. If it is inconvenient to brush your teeth after meals, you can rinse your mouth with water or tea. Second, in the process of orthodontics, in addition to following the doctor's advice, we should also pay attention to orthodontic care and avoid eating hard food, such as bone food, crabs and nuts. And avoid eating large pieces of food, such as apples, cut into small pieces before eating, and avoid the above foods to make them smaller, which can prevent the attachment of orthodontics from loosening due to improper diet and make the whole orthodontic process complete smoothly. Besides, you have to take special care of your teeth. Third, when correcting teeth, choose less traction to move teeth slowly, so as not to bring great discomfort to patients. However, in the first few days of wearing the appliance, the teeth will feel pain and discomfort. At this time, you can eat soft rice or porridge, and you can eat normally during the adaptation period of about one week (but you should pay attention to the care of teeth and braces). Fourth, when children correct their teeth, in addition to the above precautions, they should also reduce the number of snacks and sweets, especially chewing gum, because it is difficult to remove chewing gum from the appliance. In the process of adolescent orthodontics, parents should pay special attention to urging their children to follow the doctor's advice, such as going to the hospital regularly, replacing steel wires and wearing rubber bands. Otherwise, the correction process will be prolonged and the ideal correction effect will not be achieved. Finally, Astor experts remind you that you must choose a regular plastic surgery hospital for orthodontics. [Editor: Rowling]
