Zero moment of truth. That's the time for thinking about cleaning your tongue for Orabrush, which makes and sell a tongue cleaning brush, which it says helps eliminate a lot of bad breath.

For consumers "the moment of truth" comes after some ‘stimulus’ – a YouTube video, for example – says Austin Craig, social media strategist of Orabrush, at the OMMA Global event in San Francisco.

He says the company has made 100 videos over the last  year and a half. It now averages around one a week, and at the end of each video there is always a call to action – requesting  a Facebook “like” or asking for a free tongue brush sample.
