If you’re anything like me, celebrity smiles and Colgate ads make you feel guilty about your regular consumption of coffee, red wine, tea, and all the other fun things we’re told will stain our teeth.

如果你像我一样,你也会因名人们的漂亮笑容和高露洁牙膏的广告而对自己对咖啡、红酒、茶以及其他所有被认为会腐蚀牙齿的东西的经常性摄入产生罪恶感。

And the solution seems so easy – a box of whitening strips from the supermarket shelf tells us so. But does whitening teeth also remove some of what keeps them healthy? And might they be more easily stained afterwards?

而其解决方案看起来颇为简单——起码超市货架上的盒装美白条是这么宣称的。但是牙齿美白是否也清除了一些维持牙齿健康的物质呢?又或者在美白之后,牙齿更易遭到腐蚀?

We asked five experts if whitening is bad for teeth.

我们向五位专家询问,牙齿美白是否对牙齿有害。

Five out of five experts said no…

五位专家都给出了否定的答复。

But they all had a pretty big caveat. It’s safe provided it’s done by a dentist. So for this you’re looking at upwards of a few hundred dollars, rather than just a trip to the supermarket.

但他们也都做出了警告:牙齿美白必须是由牙医来操作的才是安全的。所以对于你而言,这是要花费数百美元,而非去趟超市买美白条就能解决的事。
