Teeth(牙齿)是人体口腔中重要的硬组织器官,由牙釉质、牙本质、牙骨质和牙髓构成,主要用于咀嚼食物、辅助发音及维持面部形态。作为“tooth”的复数形式,teeth在解剖学、医学和语言学领域均有广泛应用。
解剖结构
牙齿分为牙冠(可见部分)和牙根(埋于牙槽骨内)。牙釉质覆盖牙冠表面,是人体最坚硬的物质,主要成分为羟基磷灰石;牙本质构成牙齿主体,内含微管结构;牙髓位于牙齿中央,包含神经和血管。
功能分类
人类通常有32颗恒牙,包括4颗智齿(第三磨牙)。
健康关联
世界卫生组织指出,龋齿和牙周病是最常见的口腔疾病,与心血管疾病、糖尿病存在关联。每日刷牙两次(含氟牙膏)和牙线清洁是基础防护措施。
文化象征
在语言学中,“teeth”衍生出比喻用法,如“cut your teeth on something”(从某事中积累经验)。考古学中,牙齿化石为研究人类进化提供关键证据。

teeth 的核心含义是“牙齿”的复数形式,但其用法远超字面意义。它既可描述物理结构(如人类牙齿、机械齿状部件),也可通过习语表达抽象概念(如威慑力、情感状态)。需注意其不规则复数形式及文化习语的特殊用法,避免与形近词(如teethe、teth)混淆。
