使用牙線問題

刷牙前...........because firstly you remove the debit in between two teeth........then you can brush the dirt away in one time..........

I always listen to several dentists advices to their patient.......

otherwise the dirt will stick on the tooth surface when you use the floss after brushing...

刷牙後, 清算牙刷清不到的食物渣滓及預防牙石形成~

打錯了, 是 ---清除---事後可再用清水 long 一 long 口

應該就係刷牙前.

否則o係刷牙後先將牙縫內的食物殘渣 [liu] 出黎....
咁o個 d 食物o既殘渣都係會留o係口腔內架.

相反, 如果我地o係刷牙前 [liu] o左 d 食物殘渣出黎,咁之後刷牙, 咪可以連埋o個 d 污垢刷走囉~
