My friend, if you have a handsome man or a beautiful woman in your mind, but there is no tooth in your mouth, do you think it is a special scenery? In fact, a young and beautiful face is always associated with a mouthful of white and neat teeth. From ancient times to the present, many literary works are “bright eyes and white teeth” to describe the beauty of a person. And if a person’s teeth are all gone, no matter how old he is, always give people a feeling of old age, and not handsome, not beautiful. This is why? Imagine if a tent without a skeleton: only the curtain of the tent, might as well be called a sleeping bag it. Our face is like a tent, the teeth constitute the skeleton of this tent, the perioral muscles are the curtain of this tent, without the support of teeth, the perioral muscles will relax, the corners of the mouth droop, and become a “deflated mouth old lady”. As the saying goes, “the old man loses his teeth, the old man loses his teeth”, referring to the fact that as we grow older, our teeth will gradually loosen and fall out. Some people think that “old tooth loss” is a common thing, in fact, tooth loss is not a common thing, but a manifestation of periodontal disease. What is periodontal disease? It comes down to periodontal tissue. The reason why our teeth grow so firmly depends on the support of periodontal tissue, which includes gums, periodontal membrane and alveolar bone, dental bone. Periodontal tissue supports the stability of the tooth. If the periodontal tissues are damaged, the teeth will loosen and fall out, becoming “old teeth”. So, what is the “killer” that affects periodontal health? It is the plaque formed by the harmful bacteria in the mouth. In our mouth, there are a lot of bacteria, these bacteria can be adhered to the surface of the teeth through some substances, forming a soft, indefinite bacterial mass, which is the plaque. If our resistance is weakened, these bacteria will come out and destroy our periodontal tissues, just like termites collapsing a wooden house, and over time, the teeth will fall out. Therefore, maintaining healthy periodontal tissues is an effective way to prevent “old teeth”. Beauty lovers, pay attention to dental care, prevention of periodontal disease, even at a certain age, you can do “silver hair, white teeth”, “old to be beautiful”.
