牙刷的起源及刷牙技巧

隨時了解健康管理牙齒的一切資訊。

人類祖先很早有漱口、刷牙的習慣,在公元前3000年蘇美人烏爾城邦的國王墓穴中就曾發現過清理口腔用的最早工具—牙棒,一支大約能用上兩個星期。 在古希臘和羅馬時代,人們用動物骨灰做牙粉,清理口腔,現在還有些原始部落用木炭、鹽水、細砂、樹枝來清理牙齒。 阿拉伯人現在還從一種叫Arak的樹上取下樹枝,將一端搗碎,壓松,做成刷狀,用來清理牙縫及刷牙,稱之為Miswak,是一種天然牙刷,據科學家分析,這種樹枝含氟及皂素,可預防蛀牙,並有止痛作用。

既然提到了牙刷,接下去我們就來了解下為何刷牙需要3分鐘?

刷牙是為了把牙齒的外面、裏面、咬合面等各個牙面上的菌斑都去掉。這個工作量不算小,大約有80多個牙面需要清潔。要常常改變牙刷的位置,慢慢地在每個牙齒的所有牙面上轉動,一把牙刷在同一時間里只能刷到2~3個牙齒,因此每次刷牙3分鐘才能把所有牙齒都刷乾淨。
