So have I. And several dentists have actually recommended manual brushing to me as well.

On the other hand, water flossing has been a boon against dental plaque and bad breath. I used to never floss.

Disgusting mistake... A lot of food particles get stuck in the teeth interstitial spaces, macerating in there overnight or even several days... Yuck. :x
