Though heavily advertised, the whitening toothpastes only partially whiten teeth and don't provide a complete remedy.

Very few whitening toothpastes have undergone any type of clinical trial, and ones that are too abrasive can damage teeth or make them very sensitive.

It's necessary to brush with a soft-bristled toothbrush and use desensitizing toothpaste containing fluoride and either potassium nitrate or strontium chloride, because both help block the transmission of sensations from the tooth to the nerve.

If possible, purchase an electric toothbrush to remove stains and plaque more efficiently and to keep those teeth sparkling white.

雖然美白牙膏的廣告很多，但它們通常只具備部分的美白功效而沒有提供徹底的美白方案。

很少有美白牙膏經過任何形式的臨牀試驗，有些美白牙膏摩擦劑含量過多，會傷害你的牙齒或讓你的牙齒變得過分敏感。

用軟毛牙刷和含有氟化物，硝酸鉀或氯化鍶的脫敏牙膏來刷牙很有必要，因爲這兩種成份都可以阻止敏感從牙齒傳遞到神經。

如有可能，那就購買一把電動牙刷吧，這樣更有效地去除污垢和牙菌斑，讓牙齒散發出亮白光采。

【講解】

文中的whitening toothpaste就是“美白牙膏”的意思，其中toothpaste(牙膏)是合成詞，由tooth(牙齒)和paste(膏，糊)組合而成，如：a tube of toothpaste(一支牙膏)，相關詞彙還有：toothbrush(牙刷)，toothpick(牙籤)，mouthwash(漱口水)等。

最後一段中的stain作名詞，意爲“污垢，污斑”，如：The stain on his shirt is difficult to clean off.(他襯衣上的污點很難去除掉。)
