大家都知道"早晚刷牙，不长蛀牙"，但一些小伙伴可能会问："为什么一天要刷两次牙？""懒人只想刷一次，早上刷好还是晚上刷好？" 今天就告诉你为什么一天要刷两次牙？为什么晚上刷牙不能省？ 为什么每天至少刷两次牙？ 口腔健康的两大公敌：龋病（蛀牙）和牙周病（老掉牙），都是由长期附着在牙齿表面的细菌不断堆积繁殖，持续破坏牙齿和牙周支持组织导致的。 但是这些细菌并不是一开始就牢牢地粘在牙面上了，形成稳定成熟的菌斑需要一个过程： 一阶段——初期附着（0—2小时）当你刚刷完牙，其实新的牙菌斑就又开始形成了，但这时候只有少量松散的细菌借助唾液薄膜附着在牙面上。 二阶段——细菌附着（2—12小时）越来越多的细菌通过与唾液膜相互作用附着在牙面上，并且比一阶段更牢固。 三阶段——成熟菌斑（12小时后）附着的细菌开始繁殖代谢并形成复杂的生物膜结构，菌斑逐渐成熟。成熟的菌斑结构更加紧密，难以通过简单的刷牙去 除。 四阶段——完全成熟（24小时后）经过24小时，牙菌斑完全成熟，形成一个复杂的微生物群落。此时的菌斑对口腔健康威胁很大，容易引发龋齿和牙周疾 病。 从菌斑成熟的过程和时间可以看出，通过刷牙机械摩擦和牙膏辅助清洁，能够去除牙面上 ...

在口腔健康知识的海洋里，有一句简单却至关重要的"真理"，那就是"早晚刷牙，不长蛀牙"。 别小瞧了这短短几个字，它可是守护我们口腔健康的"金科玉律"！无论是咱们小时候父母在耳边的叮嘱，还是成为父母以后对孩子的念 叨，这几个字的出现频率都极高，潜移默化地督促大家养成了良好口腔卫生习惯。 但一些注重细节的小伙伴可能又会问："为什么一定要刷两次牙呢？""打工人晚上太累了，不刷也没关系吧？""我就习惯早上起来刷牙， 保持口腔清新，晚上都要睡了刷牙干啥？""懒人只想刷一次，请告诉我早上刷还是晚上刷？"…… 为什么每天至少刷两次牙？ 当你刚刷完牙，新的牙菌斑形成就立即开始了。但这时候只有少量松散的细菌借助唾液薄膜附着在牙面上。 二阶段——细菌附着( 2-12 小时)： 越来越多的细菌通过与唾液膜相互作用附着在牙面上，并且比一阶段更牢固。 三阶段——成熟菌斑( 12 小时后)： 附着的细菌开始繁殖代谢并形成复杂的生物膜结构，菌斑逐渐成熟。成熟的菌斑结构更加紧密，难以通过简单的刷牙去除。 四阶段——完全成熟( 24 小时后)： 咱们口腔健康的两大公敌：龋病(蛀牙)和牙周病(老掉牙)，都是由长期附着在牙齿表面的细菌不断堆积繁殖， ...

央视网消息：9月20日是 "全国爱牙日"，今年的主题是"口腔健康 全身健康"。在口腔疾病中，牙周炎的症状在多数情况下相对较轻，但您是否知道，它 却能引发包括心脑血管疾病在内的多种疾病，因此被称为"沉默的杀手"。这到底是怎么回事？牙周炎又该如何防治呢？ 学会爱牙护牙·警惕牙周"沉默杀手" 牙周炎可诱发心脑血管等多种疾病 数据显示，在我国，每5例死亡病例中就有2例死于心脑血管病。而在众多诱因中，有一个"沉默的杀手"，它就是牙周炎。数据显示，牙周炎患者的致命性心 脏病发生率，约为普通人的2倍，心肌梗死风险也高出30%。 不仅如此，大量医学研究证实，口腔疾病尤其是牙周炎，是多种全身性疾病的危险因素。有研究显示，孕妇的重度牙周炎，与早产、低体重儿的发生率也存 在关联。患有重度牙周炎的2型糖尿病人两年后的血糖值恶化概率，是没有牙周疾病的糖尿病患者的6倍。 尽早识别牙菌斑堆积 可防止牙周炎恶化 牙周炎自身发展相对缓慢，少有特别明显的急性症状，这是很多人并不在意的原因。那么，又是什么因素导致牙周炎的出现呢？这主要是因为附着在牙面上 的牙菌斑、牙结石。因此，对牙菌斑和牙结石的尽早识别，可以有效防治牙周问题恶化。 定期检查：每年 ...
