你不介意动物的口臭，但是对于人类就不一样了。口臭会影响你对自己以及他人对你的看法。

    是不是口臭，你只要用干净的手指伸进你的嘴里，然后从你的舌后跟刮下一些唾液。现在把它放在你手上，过一会之后闻你的手。闻起来怎么样？你就知道答案了。

    如果这个小测试证实了你有口臭，只要跟着下面的贴士做，你的清新口气就会回来：

    1.刷牙和用牙线清牙：用含氟的牙膏一天刷牙两次。别忘了刷舌头。通过刷舌头尤其是舌后跟可以降低70%的口臭。刷牙可以去除导致口臭的潜藏在嘴里的难闻细菌。用牙线清牙是必须的，因为它可以剔除隐藏的食品残留物和牙垢。

    2.每天漱口：用过氧化物漱口肯定能使你远离口气。导致口臭的细菌会被氢氧化物里的氧杀死。对于过厚的牙垢你也可以用抗菌漱口剂。

    3.喝大量的水:因唾液减少的口干也是口臭的另一个原因。所以喝充足的水和保持口腔湿润来预防口臭。

    4.不要扰乱你的胃:胃不适也可以导致口臭。吃很多抗酸剂会让酸性的胃舒服，但当你打嗝的时候会散发出口臭。试一下乳糖酶片和吃得健康。

    5.喝大量的优酸乳：优酸乳会让你的口腔更健康而且会促进大肠里有益细菌的增长。还有就是在膳食空隙吃西洋芹或芹菜也能使口气清新。

    6.嚼口香糖：嚼含木糖醇的口香糖会使你的口气清新之外，还会使唾液分泌。唾液可以帮助带走你嘴里的有害细菌。

    7.拜访你的牙医：6个月里至少要和你的牙医会面一次。检查你的牙齿和口腔测试。牙龈疾病和蛀牙是导致口臭的主要原因之一。

    如果即使在采取所有预防措施之后仍有口臭，那就要去看医生了。那可能是一个更严重的问题或感染如糖尿病，肝或肾疾病的标志。

    You don’t mind bad breath in animals but it’s a different story for people. Bad breath may affect how you feel about yourself and how others feel about you.

    bad breath, just stick a clean finger inside your mouth and try to scrape some saliva off from the back of your tongue. Now put it on your hand and smell your hand after some time. How does it smell? You have got your answer.

    If this little diagnostic test has let you down, just follow the tips below to get that fresh breath back:

    1. Brush and floss: Brush your teeth twice a day with fluoride toothpaste. And don’t forget the tongue. Bad breath has been reduced by 70 percent by brushing the tongue, especially the back of the tongue. Brushing removes the smelly bacteria lurking in the mouth that cause bad breath. Flossing is must, for it removes the hidden food particles and the plaque.

    2. Gargle everyday: Gargling with peroxide will surely keep bad breath at bay. The bacteria that cause bad breath get killed by the oxygen in the hydrogen peroxide. You can also use an antimicrobial mouthwash for excess plaque.

    3. Drink lots of water: A dry mouth with reduced saliva is another reason for bad breath. So drink enough liquids and keep your mouth moist to prevent bad breath.

    4. No upset stomachs: An upset stomach can lead to bad breath. Eating lots of antacids may ease an acidic stomach, but can cause halitosis when you burp. Try lactase tablets and eat healthy.

    5. Eat plenty of yogurt: Yogurt promotes a healthier mouth and encourages the growth of the good bacteria in your gut. One can also eat parsley or celery between meals for fresh breath.

    6. Chew gum: Chewing gum with xylitol will keep your breath fresh besides salivating your mouth. Saliva helps in washing away the bad bacteria in your mouth.

    7. Visit your dentist: Have an appointment with your dentist at least once in 6 months. Get your teeth checked and an oral exam done. Gum disease and open cavities are one of the main causes of bad breath.

    If bad breath persists even after taking all the precautions, it’s time to see a doctor. There may be a sign of a more serious problem or an infection like diabetes, liver or kidney disease.
