牙线的正确使用方法?谢谢

将牙线两端绕手两只手指上，把牙线带进牙缝，手指带动牙线对牙齿与牙龈的缝隙进行清理。具体操作如下：

一、一端绕在中指的第二指节约两圈，距离约20公分处再绕两圈于另一手中指之第二指节，如下图。

二、翻转两手，使掌心向外，同时伸直两手拇指与食指，使它们呈一直角四方形，同时拇指轻轻接触并与牙线平行，这便是牙线在两中指间的适当长，同时这也是操作牙线的基本手势。

三、牙线越过一手食指与另一手拇指头上多肉的地方。两指间保持1公分长的牙线。

四、两手指打直，指甲对指甲，把牙线带进牙缝。

五、把牙线绷紧牙齿的邻接面使其略成C形上下刮，两指同时上下运动。

六、以同样的方式，来清理同一牙缝的另一面。

【注意事项】

清理时注意牙线与牙缝的力道，不需要因为清洁不到伤害到牙龈，导致出血。牙结石严重者可至牙科处进行清洗。
