It's not exactly a newsflash that one of the most important reasons to brush your teeth is to fight off cavities (not to mention prevent bad breath). But what if the way you brush your teeth actually makes you more susceptible to cavities, tooth decay and gum disease? Scary.
刷牙的最重要原因是拒絕蟲牙（別再說是預防口臭），這已經不是新聞了。但是要是你刷牙的方式實際上更容易讓你的牙齒蛀牙，產生牙齒蛀蝕和得牙齦疾病呢？這就很可怕了。

Turns out, there are a host of common mistakes that many of us make morning and night that can damage teeth and turn a healthy smile upside-down. Find out what you're doing wrong -- and how to break these bad habits for better teeth.
事實證明，我們在早晚刷牙中會犯很多普遍的錯誤傷害我們的牙齒，讓我們的微笑都打上了不健康的記號。找出你錯在哪里—然后為了讓牙齒更健康，應該怎么丟掉這些惡習。

1.You don't brush for long enough.
1.你刷牙時間不夠。

Most dentists recommend brushing for two or three minutes, but few people ever make it to that. Next time, check your watch to see how long your routine takes.
大多數的牙醫(yī)都建議人們刷牙要刷兩到三分鐘，但是很少有人能做到。下一次，盯著手表看看你花了多少時間。

2.You're not watching what you're doing.
2.并未專注自己在干什么

Make a point to look in the mirror while you brush your teeth and see where the brush is actually going. It's easy to miss the area right at the gum line, which is the most important part.
在刷牙的時候，對著鏡子注意一下你的牙刷刷在了什么地方。我們很容易漏刷牙齦那一部分，這是最重要的一部分。
