Instead of just cleaning teeth, I’d like to see a toothpaste that multi-tasks.
It could contain tryptophan (and taste like turkey), so that when you brush at night, it also makes you a little bit sleepy.
And then, there could be a special morning toothpaste that contains caffeine or some other stimulant, so that it helps wake you up.
Of course, the real beauty of this marketing gimmick is that people would buy twice as much toothpaste – a “morning” tube and an “evening” tube. I think it’d be best if both kinds came in a single tube, perhaps with a cap on each end – there would still only be half as much in each tube, but people wouldn’t have to try to figure out how to fit two tubes of toothpaste in their medicine cabinet.
