During the period of wearing fixed aligners (commonly known as fixed braces), there are some precautions that need special attention: Precautions when eating: During the treatment of fixed aligners, you cannot eat hard (such as fried hard twists, pine nuts, crispy bones, etc.) sticky (such as milk candies, patties, etc.) food, make large pieces of food smaller before eating (such as apples not directly chewed, but cut into thin slices after eating with the back teeth), food with bones to pick off the meat Eat, do not let any bone and oral contact. To prevent damage to the aligner. If the orthodontic appliance loosens, the arch wire breaks, etc. and affects the oral function, you should contact me promptly by phone or Internet contact to determine if you need to come to the hospital to deal with the situation. Oral hygiene maintenance after eating: Patients wearing fixed orthodontic appliances need to pay special attention to oral hygiene. Morning, noon and night and after any meal (such as snacks, snacks, etc.) must be brushed in a timely manner, to brush the teeth carefully to clean the soft scale and retained food, to prevent the accumulation of plaque, otherwise the orthodontic appliance and the surrounding bacterial reproduction and plaque buildup is not only easy to cause inflammation of the gums, periodontal tissue, but also easy to lead to tooth demineralization and tooth decay. In view of this, it is highly recommended (and required) that patients undergoing orthodontic treatment have a small-headed toothbrush and a small tube of toothpaste in their bag to brush their teeth promptly after eating, and clean every side of the mouth from front to back, especially around the aligners, in view of the fast pace of life and the fact that students and working white-collar workers usually eat Chinese food near their schools or offices. It is important to note that cleaning the aligners with normal soft bristle toothbrush bristles will not cause damage to the aligners and there is no need to be concerned about this. Soreness and swelling of the teeth after the force: After the first orthodontic appliance and each follow-up visit with force, the teeth may experience soreness and mild discomfort, which generally lasts 3-5 days and then reduces and disappears. There is no need to take pain relieving medication. If there is sudden and intense pain, or if other conditions arise, you should contact me promptly for an examination and treatment. Mucosal symptoms of the first orthodontic appliance: After the first orthodontic appliance and each follow-up consultation and force, the oral mucosa near the teeth may be worn and changed because of the orthodontic appliance and the corresponding mucosal symptoms and discomfort, these symptoms will usually be relieved after a period of adaptation (three to five days), if the discomfort is strong during the period, you can cooperate with the “orthodontic mucosal protection wax If the discomfort is strong during this period, you can use it together with “orthodontic mucosal protection wax”.
