　　2. Tooth brush should be replaced more often

　　勤换牙刷

　　Do you keep track of how often you replace your old tooth brush? It all starts with small items, so please pay attention to how new your tooth brush is. Why is it so important? The answer is simple. The older your tooth brush is, the more bacteria it accumulates. Such a brush causes more harm than good. Purchase a new tooth brush and learn to clean your mouth properly. Brushing only your teeth is definitely not enough. Massage your gums, clean your tongue and gargle your throat twice a day. The same rule applies to electric tooth brushes. Depending on the frequency with which you use the brush, change the head more often than you used to.

　　你是否注意过自己多久换掉旧牙刷?一切都是从小事开始的，所以你要注意牙刷是否总是新的。这为什么如此重要?答案很简单。你的牙刷越旧，上面积聚的细菌越多。这样的牙刷有百害而无一利。去买个新牙刷，学学如何正确刷牙。只刷牙绝对不够，还要按摩牙龈、清洁舌头、漱喉咙，这些每天都要来两次。电动牙刷也是如此，根据你用牙刷的频率，要比从前更勤更换牙刷头。

　　3. A few tasty treats to keep your teeth white

　　少吃好吃的来保持牙齿洁白

　　Some of us strongly believe that food and drinks consumed by us can damage our teeth. This is partly true and if you eat plenty of beetroot, black currant or drink red wine, black coffee and tea on a regular basis, then your teeth might not look as white as you would like. Avoid snacks and foods that have artificial colors, such as candies and sodas and replace them with healthier options. Luckily, there are foods than are healthy for your health. You can significantly improve your dental hygiene if you eat apples, celery, broccoli and spinach. Fruits and vegetable are full of minerals that can make your teeth whiter and your enamel stronger.

　　我们中有些人坚信我们食物和饮料会损坏牙齿，这种说法不完全正确，如果你经常吃太多甜菜根、黑加仑或喝红酒、黑咖啡和茶的话，那你牙齿的洁白程度可能就不尽如人意。不要吃含人工色素的零食或食物，比如糖果和碳酸饮料，你可以选择更健康的替代品。所幸有很多食物对健康很有好处。吃苹果、芹菜、西兰花和菠菜都可以显著改善口腔健康。水果蔬菜都富含矿物质，可以美白牙齿、坚固牙釉质。

　　4. Use a special straw with your drinks

　　用一种特殊吸管喝东西

　　It is easy to avoid unwanted stains on your teeth. All you need to do is to use a straw with drinks that are harmful to teeth. Usually, when we drink the liquid inevitably gets in contact with our teeth. If your tooth enamel is porous, the colors contained in beverages easily absorb into it and your teeth lose their natural whiteness. We recommend you should visit an online store and order a package of straws. Straws do not cost much. On the contrary, you will save a lot since you will not need to spend money on tooth whitening procedures performed by professionals.

　　避免牙齿上出现讨厌的斑点很容易，你需要做的就是用吸管喝对牙齿不好的饮料。通常我们喝东西时，饮料不可避免会接触牙齿。如果你的牙釉质不坚固，饮料的颜色就很容易渗入牙釉质，牙齿就失去了自然的洁白。我们建议你去网上商店买一包吸管。吸管用不了多少钱，相反，你可以省下很多钱，因为你不需要花钱找专业人士帮你美白牙齿了。

　　5. Oil pulling helps your overall oral health

　　油拔帮助你全面提升口腔健康

　　This tip might sound bizarre and hard to believe in. Oil pulling can help you avoid a lot of other health problems related to dental hygiene. This procedure can greatly improve the color of your tooth enamel, digestion, vision and even hair and nail growth. Now let us teach you how to pull oil. Purchase a bottle of oil. Make sure that the oil is organic and cold pressed. Olive oil or coconut oil will do just fine. Put a spoonful of the product in your mouth. Swish the oil for a couple of minutes and then start pulling it through your teeth. Do this for about 5-10 minutes. Practice it every day and you will soon see the results. Oil disinfects, washes away bacteria and kills parasites. Try out different oils and pick your favorite.

　　这个建议可能听起来有点怪，很难让人相信。油拔能帮助你避免很多其他与口腔健康有关的问题。这种方法能大大改善牙釉质颜色、消化系统、视力、甚至头发和指甲的生长。现在我来教你如何油拔。先买一瓶油，一定要买有机冷榨的油，橄榄油或椰子油也可以。在嘴里放一匙油，在嘴里翻滚几分钟，然后在齿间推拽，如此进行5-10分钟。每天都做，很快就能看出效果。油能消毒、清洁细菌、杀死寄生虫。尝试不同的油，然后选一种你最喜欢的。

　　6. Gargle your mouth with apple cider vinegar

　　用苹果醋漱口

　　Apple cider vinegar should be in your food pantry at all times. It improves your health from inside out and does not require you to have loads of money. It is known that apple cider vinegar can make your smile more appealing. Start your next morning with a simple procedure – gargle it, spit it out and then brush your teeth. The vinegar removes stains on the enamel plus kills harmful bacteria building up on your tongue, gums and teeth. It might take you a bit of time to get used to the taste. Do not worry, you will soon develop tolerance. Keep in mind that apple cider vinegar is better since gargling regular vinegar is too challenging for most people.

　　食品柜里应该常备苹果醋。它能由内而外改善你的健康，还不需花太多钱。众所周知苹果醋能使你的微笑更迷人。明天早上开始采取这个简单步骤——漱口、吐掉然后刷牙。苹果醋能去掉牙釉质上的污点，还能杀死舌头、牙龈和牙齿上的有害细菌。你可能需要一段时间才能适应这个味道。别担心，你很快就能忍受了。记住苹果醋更好，因为用普通醋漱口对大多数人来说太具有挑战性了。
