 And that's why I use Spry, S-P-R-Y, toothpaste, mouth rinse. I even chew their gum and their mints, suck on their mints, because it is important to keep the bad germs out of the oral cavity. And that's what Spry does. It tricks the germs into believing there's food there when it's really not. Now this stuff is delicious, too. It comes in peppermint, cinnamon, and spearmint.
