So, what dietary habits need to pay attention to during orthodontics? 1, the first time to wear orthodontic appliances dietary principles in the first time to wear orthodontic appliances or orthodontic wires, because the teeth are subjected to orthodontic forces, from no force to a sudden state of force, most people will feel pain, even open your mouth are reluctant, let alone eat. Therefore, you should eat soft food for the first two to three days, that is, thin rice, noodles and so on. Depending on your adaptation, you can decide when you can resume eating rice. 2, the usual food to avoid eating (1) too hard food to ban avoid, like sugar cane, ribs, crabs, ice, etc., ribs, chicken legs, beef jerky, snacks with cores with shells, etc., because eating such food must spend more effort to bite or chew, will bite the aligner loose, but also the orthodontic wire bite deformation, affecting the movement of teeth. (2) Too sticky food should be avoided as much as possible, like maltose, rice cakes, glutinous rice products, chewing gum, glutinous rice products, milk sugar, etc., will stick up the aligners and orthodontic wires and cause displacement. (3) High-sugar foods should be avoided as much as possible, such as common candy, cookies and other snacks, in order to avoid tooth decay, it is best to eat less during the orthodontic period, and if you really can not resist eating, you must also brush your teeth immediately. (4) Try not to drink drinks with high sugar content, such as cola, Sprite, juice, etc. 3, to take in more food Tooth movement is dependent on periodontal bone absorption and deposition, and a balanced diet will help the movement of teeth. During the orthodontic treatment if the nutrition is not balanced, be careful to affect the effect of treatment, so it is more important to pay attention to a balanced diet. Eat more vegetables and fruits (note that apples should be cut into small pieces so that the brackets do not loosen), and take more vitamins, which can reduce mouth ulcers and orofacial infection. Many people who wear orthotics will be more prone to mouth ulcers or rotten corners of the mouth than ordinary people because they react to the stimulation of the orthotics. So you should be more conscious of getting enough vitamins, and food therapy is the easiest and most effective way to do this. Lemon, grapes, strawberries, mangoes, watermelon, tomatoes, cantaloupe, asparagus, cauliflower, collard greens, spinach, potatoes, etc. are rich in vitamin C, may wish to take in more. 4, the principle of chewing teeth above the orthodontic appliance, it is difficult for anyone to eat freely, so no matter what food you eat, it is best to chew slowly to avoid biting into the flesh or make the orthodontic appliance loose. If you encounter biting food like apples, it is best to eat in small pieces to avoid biting off the aligners. Be sure to keep chewing on both sides in turn. There are many people who do not realize that they are in the habit of chewing on both sides. There are very few people who chew on both sides at the same time, and most people chew on both sides alternately and in turns, which is considered bilateral chewing. But there are some people who are used to chewing only on one side, which has more negative consequences: it causes TMJ disease, the side that does not apply no matter how hard you try to maintain the cleanliness is very poor (so the orthopedic surgeon will look at the two sides of the cleanliness is very far apart and judge you as a detective is partial chewing habit) no matter how you are not used to using the other side, you have to force yourself and train yourself to use the waste side to chew.
