Teeth(牙齒)是人體口腔中重要的硬組織器官,由牙釉質、牙本質、牙骨質和牙髓構成,主要用于咀嚼食物、輔助發音及維持面部形态。作為“tooth”的複數形式,teeth在解剖學、醫學和語言學領域均有廣泛應用。
解剖結構
牙齒分為牙冠(可見部分)和牙根(埋于牙槽骨内)。牙釉質覆蓋牙冠表面,是人體最堅硬的物質,主要成分為羟基磷灰石;牙本質構成牙齒主體,内含微管結構;牙髓位于牙齒中央,包含神經和血管。
功能分類
人類通常有32顆恒牙,包括4顆智齒(第三磨牙)。
健康關聯
世界衛生組織指出,齲齒和牙周病是最常見的口腔疾病,與心血管疾病、糖尿病存在關聯。每日刷牙兩次(含氟牙膏)和牙線清潔是基礎防護措施。
文化象征
在語言學中,“teeth”衍生出比喻用法,如“cut your teeth on something”(從某事中積累經驗)。考古學中,牙齒化石為研究人類進化提供關鍵證據。

teeth 的核心含義是“牙齒”的複數形式,但其用法遠超字面意義。它既可描述物理結構(如人類牙齒、機械齒狀部件),也可通過習語表達抽象概念(如威懾力、情感狀态)。需注意其不規則複數形式及文化習語的特殊用法,避免與形近詞(如teethe、teth)混淆。
