1. Go On a White-Teeth Diet
What goes into your mouth shows up on your teeth. So if you're drinking a lot of red wine or black tea, or smoking cigarettes, expect the results to show up as not-so-pearly whites. Other culprits include colas, gravies and dark juices. The bottom line: if it's dark before you put it in your mouth, it will probably stain your teeth. Step one: brush your teeth immediately after having foods that stain. Step two: regularly use a good bleaching agent from your dentist. Step three: be conscious of tooth-staining foods and drinks, and have them only when a toothbrush is around. If not, have an apple for dessert.

1. 吃美白牙齿的食物
你吃到口里的东西最终会反映到你的牙齿上。如果你一直喝大量的红酒、红茶，或吸大量的香烟，就别期望牙齿会如珍珠般洁白。其它的罪魁祸首包括：可乐类饮料、浓卤汁和深色果汁。饮食底线：要清楚地知道，入口之前，食物如果是深颜色的，就可能把你的牙齿染上颜色。步骤一：吃了这种食物后立即刷牙。步骤二：定期地使用牙医推荐的好的漂白剂。步骤三：要小心污染牙齿的食物和饮料，只有牙刷在身边时才享用这些食物。如果没有，就用苹果作为餐后甜点吧。

2. Hum While Brushing Your Teeth

The ideal amount of time to brush to get all the bacteria-packed plaque out is at least two minutes. Use your watch or keep a timer in the bathroom and set it for 2 minutes. Or find a tune that lasts about two minutes and hum it to the end.

2. 刷牙时哼首歌吧
要把满是细菌的牙斑完全刷干净，理想的时间长度为至少2分钟。用手表计时或者在卫生间里放一个计时器，定时2分钟。或者找一支两分钟长度左右的歌曲，刷牙时把它哼完。

3. Grip Your Toothbrush Like a Pencil

Does your toothbrush look as if it's been used to clean the car? If so, you're probably brushing too hard. Contrary to what some scrub-happy people think, brushing with force is not the best way to remove plaque. The best way is to place your toothbrush at a 45-degree angle against your gums and gently move it in a circular motion, rather than a back-and-forth motion. Grip the toothbrush like a pencil so you won't scrub too hard.

3. 像拿铅笔一样握着牙刷
你的牙刷是不是看上去像用它清洗过一辆汽车一样？如果是，你可能刷得太用力了。相反，那些习惯于“欢乐擦洗”的医务工作者们认为，用力刷牙并不是除去牙斑最好的方法。最好的方法是放置牙刷与牙龈成45度角，并让牙刷轻轻地以圆周运动移动，而不是前后移动。像拿铅笔一样握着牙刷，这样你就不会刷得太厉害了。

4. Drink a Cup of Tea Every Day

Flavonoids and other ingredients in tea seem to prevent harmful bacteria from sticking to teeth, and also block the production of a type of sugar that contributes to cavities. Tea also contains high amounts of fluoride.

4. 每天一杯茶
茶叶里的黄酮类物质和其它成分似乎可以阻止有害细菌附着在牙齿上，还可以阻止引起蛀牙的糖类物质的产生。茶叶也含有大量坚固牙齿的氟化物。

5. Replace Your Toothbrush Regularly

Throw away your toothbrush or change the head of your electric toothbrush at least every two to three months. Otherwise, you're just transferring bacteria to your mouth.

5. 定期更换牙刷
至少每2到3个月就要扔掉你的旧牙刷或者更换电动牙刷的刷头。否则的话，你就是把细菌往口里送。

6. Use Alcohol-Free Mouthwash

Most over-the-counter mouthwashes have too much alcohol, which can dry out the tissues in your mouth, making them more susceptible to bacteria. Some studies even suggest a link between mouthwashes containing alcohol to and an increased risk of oral cancer. To be safe, be a teetotaller when it comes to choosing a mouthwash.

6. 使用无酒精漱口水
绝大多数柜台上出售的漱口水，都含有太多的酒精，它们会吸干你口内组织的水分，使用它们更易受到细菌的侵害。一些研究甚至表明，漱口水内包含的酒精和口腔癌发病风险的增加有一定的联系。为了安全，在选择漱口水时，做一名彻头彻尾的禁酒者吧。
