After about 2-3 times of initial and follow-up consultation in the early stage, patients who need to extract the teeth can put in the fixed orthodontic appliance (bracket) after the teeth are extracted, and many patients and friends may not understand: this bracket is bonded to the teeth by the doctor with a special bonding agent (resin), and its bonding force is able to withstand the force when you eat normally and when the appliance puts force on it, and it will not be damaged in general. However, you can’t eat too hard food after putting in the aligners, which will lead to the dislodging of the brackets, which will not only incur extra cost, but also affect the effect of the treatment and the course of treatment, so please pay attention to it! 1, a brief introduction may lead to the bracket off the food: (1) all kinds of food with bones: such as ribs, chicken wings, chicken claws, crabs, pig’s feet, duck necks, etc., this kind of food to eat when you have to be sure to remove the inside of the bone and then eat, otherwise it is very easy to damage the orthodontic appliances; (2) have shells or nuclei of the fruit: fruits are often eaten, but wear into the orthodontic appliances and then eat must be careful, the shells of the fruit or nucleus The shell or core of the fruit is very easy to drop the brackets. Such as dates, plums, sugar cane, etc. is almost the “killer” of the orthodontic appliances, almost every time you eat must fall. However, we are not let everyone in the long 2-3 years of orthodontic treatment process no longer eat fruit, such as apples, peaches, oranges, pears and other fruits, we only need to use a fruit knife to remove its skin or core, and then cut into small pieces of no problem, do not take the whole fruit directly to bite; (3) In addition, there are such as fried peanuts, fried soybeans, dry broad beans and other dry fruits, did not cook the dry instant noodles, baked cakes and so on should also be careful, the best! Do not eat, this kind of food is also very easy to damage the brackets; (4) Finally, teenage patients should also pay attention to the meal time do not chat, fooling around, there are often children in the meal time due to inattention, chopsticks, spoons, etc. to the orthodontic device damage. 2, it is best not to eat too sticky food now teenage children oral hygiene is generally poor, when wearing into the orthodontic appliances, the mouth will increase a lot of wire-like devices, oral hygiene will be more difficult to deal with, you can imagine when you eat too sticky food you will need to usual time to clean up the mouth a few times? And most of the teenagers nowadays have a very tight study schedule and don’t have much time to brush their teeth at all. Therefore, in order to reduce this trouble of cleaning oral hygiene, we had better eat less milk candy, sticky cake, snacks, dumplings and other foods. 3.After wearing fixed orthodontic appliances, oral hygiene will be more difficult to clean.
