7.You're failing at?flossing.
7.你不會(huì)用牙線清理。

Start with a full foot of floss, twirling the ends around the middle finger on each hand. Use your thumb and forefinger to gently work the floss between two teeth, being careful not to pull it roughly or saw it back and forth, both of which can injure the gum. Wrap the floss around one tooth and wipe up and down to loosen and remove plaque. Then do the same on the next tooth and repeat.
開始用一段牙線，將線的兩段纏在左右手中指上。用你的食指和拇指輕輕地在兩齒之間撥動(dòng)牙線，小心一點(diǎn)不要太粗魯或前后牽動(dòng)，這樣會(huì)傷害到牙齦。將牙線纏在牙齒上，上下前后拉動(dòng)，清除附著在牙齒上的菌斑。然后換旁邊的牙齒，重復(fù)相同的動(dòng)作。

8.You don't rinse after.
8.刷完牙后未沖洗。

Effective brushing and flossing unbind bacteria-laden plaque from the surface of teeth. Rinsing afterward is a key step to make sure that bacteria leave your mouth for good.
有效的刷牙和使用牙線能使細(xì)菌斑快速從牙齒表面脫離。在洗完后再次漱口是很關(guān)鍵的一步，確保細(xì)菌已從嘴里離開。
