Core Viewpoint - A recent investigation reveals that DIY dental resin materials marketed online are being misused by consumers, leading to adverse health effects. The article emphasizes the importance of understanding dental health and avoiding common misconceptions and unreliable home remedies [1]. Group 1: Bad Habits Leading to Tooth Decay - The classic four factors of dental caries are bacteria, food, host, and time. Poor dietary and behavioral habits, along with inadequate oral hygiene, contribute to tooth decay [2]. - Consumption of sugary drinks, late-night milk or juice, binge eating, and frequent intake of coffee and alcohol can harm teeth.

其实，许多成年人也有同样的烦恼——明明坚持刷牙，却还是逃不过蛀牙的侵扰。 赵媛介绍，人们常说的"蛀牙"，在牙科专业领域称为"龋齿"，它并非牙齿"被虫子啃了"，而是一个由细 菌主导的化学腐蚀过程。 "龋齿的出现，离不开牙菌斑'作祟'。"赵媛介绍，牙菌斑是由细菌、食物残渣和唾液构成的生物膜，里 面的细菌会利用食物残渣发酵产生酸性物质，逐渐腐蚀牙齿外层的牙釉质等硬组织。时间一久，就会导 致牙齿脱矿、硬组织结构崩塌，形成肉眼可见的龋洞。 蛀牙的发病率较高，是口腔常见疾病之一，其诱因多样，包括口腔卫生不良、饮食习惯不佳等。此外， 牙齿的先天结构和唾液质量也会影响患蛀牙的概率，如牙齿窝沟较深，容易藏匿细菌；牙釉质矿化程度 不足，更易被酸腐蚀；唾液分泌过少或成分异常，会削弱口腔自洁能力，提高蛀牙发生风险。 天天刷牙，为什么蛀牙还是找上门？是刷牙的"姿势"不对，还是防蛀的"打开方式"有待提高？在牙齿清 洁与防蛀之间，藏着哪些被忽略的细节？ 今年9月20日是第37个"全国爱牙日"，本报记者采访了兰州大学口腔医院牙体牙髓科主任医师赵媛教授 团队，从蛀牙成因、刷牙方式到科学防护，为您解析护牙防蛀的窍门。 认识蛀牙 细菌产酸是"元凶 ...
