As you can see in this strange ad from Thailand, Dentiste's "nighttime" toothpaste claims to fight bad breath as you sleep. But doesn't regular toothpaste do that? There doesn't seem to be any special ingredient that sets Dentiste apart, unless you count the soap-opera acting on display here. (That may scare the impurities away on its own.) The ad is from JEH United, the same ad agency that did the weirdest light-bulb ad of all time.
