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， ...

Core Viewpoint - The article discusses the issue of "gum recession," also known as "gingival recession," which is a common symptom associated with periodontal disease. It emphasizes that this condition is not directly related to aging and highlights the importance of proper oral hygiene to prevent further complications [1][2][4]. Group 1: Causes and Prevention - "Gum recession" is primarily caused by untreated periodontal inflammation and improper brushing techniques, rather than aging [2][4]. - Correcting improper brushing habits can effectively prevent further gum recession [3]. - Most individuals experiencing gum recession are likely suffering from advanced stages of periodontal disease, which can be managed with timely treatment and good oral hygiene practices [3][4]. Group 2: Health Implications - Gum recession can lead to significant health issues, including root sensitivity, food impaction, and potential tooth loss [4]. - The presence of gum recession indicates that periodontal disease has progressed to a serious level, which may result in further complications if not addressed [4]. Group 3: Misconceptions - Common misconceptions include the belief that dental cleaning causes gum recession, when in fact, the recession may have already occurred due to underlying issues [7]. - Another misconception is that bleeding gums during brushing should be avoided, whereas it is a warning sign that requires continued attention to oral hygiene [8]. - The idea that tooth loss is inevitable with age is incorrect; maintaining good oral hygiene from a young age can lead to retaining a healthy set of teeth into old age [10].

新华社北京9月18日电（记者李佳巍）"一直早刷晚刷，足够重视，为啥牙齿还是老出问题？"时不时响起"警报"的牙齿健康，让不少一天两次"按 时足量"刷牙的网友疑惑不解。 陕西省西安市新城区通济坊小学的学生在西安交通大学口腔医院口腔科普教育基地学习正确的刷牙方法。新华社记者 李一博 摄 横向"拉锯式"刷牙，错！ "众多牙病患者都存在牙齿楔状缺损问题，而长期错误地横向'拉锯式'刷牙正是罪魁祸首。'越用力刷牙越干净'是个误区，这个举动就像拿砂纸磨 损牙颈，对牙齿造成的损伤不可逆。"北京大学口腔医院预防科主任医师荣文笙说。 为何刷牙不能横向"用力过猛"？专家介绍，牙釉质是人体最坚硬的组织，是保护牙齿的"盔甲"，但其厚度呈"山峰-山谷"分布，即牙冠部（咀嚼 面）最厚，牙颈部（牙龈边缘）最薄。横向刷牙时，刷毛与牙齿形成45°角切割力，长期作用就像用钢锉反复摩擦薄弱的"山谷"。 荣文笙说，许多人日常习惯侧重牙齿表面清洁，喜欢刷"顺手"的地方。而对于牙齿缝隙处往往忽视，清洁难以触达牙龈边缘、牙间隙等部位，这 一清洁"盲区"往往成为牙菌斑滞留重灾区，给"蛀牙刺客"邻面龋发生以及牙周疾病的发展提供了繁衍温床。 牙周病是影响我国居民口 ...

Summary by Sections Gum Recession Overview - Gum recession, or gingival recession, refers to the retreat of gum tissue, exposing the tooth roots and potentially leading to tooth mobility and loss [3][4]. - Symptoms include swollen gums, bleeding while brushing, sensitivity to temperature changes, and visible gaps between teeth [6]. Prevalence and Causes - A significant portion of the population, around 50%, experiences gum recession, particularly affecting the aesthetics of front teeth [8]. - The primary cause of gum recession is the accumulation of dental plaque, which leads to chronic irritation and inflammation of the gums [10].
