? Rinsing your mouth and brushing your teeth after meals is good for keeping your mouth clean and your teeth healthy. Gargling after meals is a good hygienic habit. Zhang Zhongjing, a medical sage, said in The Synopsis of the Golden Chamber: "Rinse your mouth several times after meals, so that your teeth will not lose their fragrance", which clearly explained that you should pay attention to oral hygiene after meals and rinse your mouth frequently after meals. This is because, under the action of bacteria and biological enzymes in the oral cavity, food residues adhering to the oral cavity and between teeth after meals will produce nitrite and other harmful substances, which are easy to produce diseases such as dental caries, bad breath and periodontitis. Therefore, the ancients said that "to strengthen the tongue and wash tea after meals". These dietary principles of the ancients not only inspired us, but also proved by modern science to be an effective prescription for health care and longevity.
