应该先牙线，后刷牙 While it may be surprising, a study has found that flossing first followed by brushing with a fluoride toothpaste is more effective in removing interdental plaque than brushing first, flossing second. In addition, flossing before brushing results in greater fluoride retention between teeth. This is because flossing loosens the bacteria, plaque, and other residue between teeth. When followed by brushing and rinsing with water, more particles are flushed out from those hard-to-reach interdental spaces.
懒得时候就直接刷刷牙算了。 我以前好长时间晚上都不刷牙， 很懒， 习惯了。 呜呜。
没错 但是实际操作中总是习惯先floss
哎，强迫症每天flossing半天，我都是先刷后flossing, 有天又看见人说应该先flossing后刷牙，问问大家的顺序，哈哈哈 flossing真的很有用，牙龈不会出血，牙垢也没有，不flossing的朋友们要flossing啊 目前比较多的票是先flossing后刷牙，我还真有可能搞错顺序了，N年了。
Same
随便google了一下，牙膏厂，牙医，research都说应该先floss后刷牙。当然反过来也没啥大不了的。
其实有点区别，我后知后觉体会到的，不flossing刷完牙之后，牙缝里有东西，先flossing再刷会更clean. old habits die hard, 我要改过来。
牙医说过flossing绝不能代替刷牙。

牙医给你先刷牙再floss是因为他们觉得这个顺序对他们自己更卫生
其实区别很小的, 只要肯用就差不多行了.
先洗澡
bingo!
