Tooth Brushing

刷牙

Traditional wisdom is that we should brush twice a day, after meals. Well, actually, our obsessive-compulsive tooth-brushing practices lead to deterioratingoral health, including increased numbers of cavities and eventual tooth loss.

每天飯后刷牙？傳統(tǒng)智慧不管用啦。其實(shí)每天的義務(wù)刷牙會(huì)損害口腔健康，造成蛀牙增多和牙齒脫落。

The reason is that the acidityin food and beverages causes tooth enamel to soften, and brushing right after eating an acidic meal strips enamelfrom the teeth, leaving them vulnerable to cavities. Leaving a little food behind actually doesn't cause as much damage as your toothbrush does as it scrubs the natural protective layer off the teeth.

食物和飲料中的酸性會(huì)造成牙齒釉質(zhì)軟化，馬上刷牙容易得蛀牙。嘴里留點(diǎn)食物的害處絕對(duì)沒(méi)有馬上刷牙大。

So how the hell are we ment to do it?

那我們?cè)撛趺此⒀溃?/p>

Studies show that flossing is much more important than brushing. Dental flossactually removes the bacteria that clump together between your teeth, without scrubbing and stripping layers off them.

用牙線清潔牙齒比刷牙要重要得多。牙線可以在不破壞牙齒保護(hù)層的情況下清理牙齒間堆積的細(xì)菌。
