When orthodontic braces are worn, there is a lot of structure on the surface of the teeth. After eating, there will be more food residue in the orthodontic appliance and in the crevices around the teeth, so you need to rinse your mouth in time. Rinsing your mouth after eating and carefully brushing your teeth with a toothbrush is the most important care for your teeth after wearing braces. If the food residue is not cleaned out in time, it will easily cause demineralization on the surface of the teeth and even decay, and will cause gingivitis and periodontitis. Therefore, it is generally recommended to go to the hospital for dental cleaning every six months or so to thoroughly clean out the calculus, food residue and soft scale around the teeth.
