如何正確清潔牙齒
You need to systematically go round all the surfaces of your teeth with fluoride toothpaste, for at least two minutes, twice a day. Unfortunately, we live such busy lives that putting two minutes aside feels like a lifetime for some people.
你需要有系統地使用氟化物牙膏繞你牙齒的所有表面，持續至少兩分鐘，一天兩次。不幸的是，我們過着忙碌的生活，所以留出兩分鐘對一些人來說就像一輩子一樣。
Your teeth tend to be a bit softer just after eating, so wait at least half an hour. Then brush all along the gum line with a little scrubbing action. Don't press too hard, or to be too light.
吃完東西后，你的牙齒會變軟一點，所以至少要半個小時後才能刷牙。然後沿着牙齦線輕輕洗刷一下，不要太用力，也不要太輕。
It is very important that you reMove the bacteria – the dental plaque – from your teeth. If you don't remove that, your gums will get irritated, then bleed. Some people think this means they need to let them heal, but all that happens is the bacteria stay on your teeth. If you want to be sure you're doing it effectively, buy some plaque-disclosing tablets from the chemist, which will stain the bacteria that remain.
清除牙齒上的細菌（牙垢）十分重要，如果你不處理它們，你的牙齦就會發炎，然後開始出血。某些人認爲只需要等着傷口癒合就行了，其實則不然，牙齒上的細菌纔是導致牙齦出血的原因所在。如果你想確認一下牙齒是不是刷乾淨了，僅需從藥店買一些牙菌斑顯色劑就行，這樣就能看到殘留的牙垢了。
There is some evidence that small-headed electric toothbrushes tend to be a bit better than manual brushes – but make sure you still use them in a systematic way.
有證據表明小型電動牙刷比起我們平時用的牙刷更有清潔力度，但是也要確保你仍然使用一個科學系統的方法去使用電動牙刷。
Brushing your teeth fights gum disease; fluoride toothpaste stops the decay. spit the toothpaste out but don't rinse out. Mouthwash by itself is not going to do the job that brushing with toothpaste does. If you do want to use mouthwash, again spit rather than rinse.
刷牙可以預防牙齦疾病；含氟牙膏可以防止蛀牙。把牙膏吐出來，但不要衝洗乾淨。漱口水本身並不能起到牙膏刷牙的作用。如果你想用漱口水，反覆作用後再吐出。
Ask your dentist or hygienist about flossing. For most people, good brushing will be enough. Others may be more susceptible to gum disease and have to do more, such as using interdental brushes (for gaps between teeth) and floss (where your teeth have tight contact).
可以諮詢牙醫或衛生員關於使用牙線的問題。對大多數人來說，好好刷牙就足夠了。其他可能更容易患牙齦疾病的人，則需要做更多。比如使用牙間刷(用於牙齒間隙)和牙線(牙齒緊密接觸的地方)。
