一天應該刷幾次牙 專家教你怎樣刷牙纔對牙齒最好(2)

How often?

多久刷一次牙？

"The best way to prevent tooth decay is to brush teeth twice daily with a fluoride toothpaste to remove plaque, limit the frequency, and amount of sugary food and drinks consumed in your diet, and see the dentist regularly.

“預防蛀牙的最好辦法就是一天用含氟牙膏刷兩次牙，因爲含氟的牙膏可以幫助去除牙菌斑，除此以外還需要控制含糖飲食的次數和攝入量，並定期看牙醫。”

Don'ts

該避免的事：

1. Brush for long enough – research indicates that people only brush for 45 seconds

1. 刷牙時間不要太短。研究發現很多人刷牙只刷45秒左右。

2. Rinse the mouth after brushing – fluoride helps to prevent, control and even stop tooth decay – but rinsing the mouth out dilutes the concentration of fluoride, so SPIT, don’t rinse.

2. 刷牙後不要使勁漱口。氟化物能預防、控制甚至讓齲洞停止進一步發展，但使勁漱口會稀釋氟化物，所以直接吐出來就好了。

3. Brush too soon after eating – as enamel on teeth is softened after eating especially with sugary foods – it’s best to wait an hour before brushing which allows the tooth to harden up more.

3. 進食後切勿立馬刷牙。進食後——尤其是吃了甜食後——牙釉質會軟化，所以最好過一個小時等待牙釉質恢復後再刷牙。

4. Use a hard bristle toothbrush as this can damage the soft tissues in the gums.

4. 別用硬毛牙刷。硬毛牙刷會傷害牙齦組織。

5. Don't brush too hard – the bristles should lightly sweep the tooth.

5. 刷牙不要太使勁。刷毛應該輕輕掃過牙齒。
