Fresh breath centres

My toothpaste is "endorsed by fresh breath centres worldwide". Not just one fresh breath centre – oh no! – but fresh breath centres all around the world. It must be special.

Out of curiosity, I googled 'fresh breath centre'. The informative fresh breath centre website has a 'could you have bad breath?' online test. The first question: "Has anyone ever told you you have bad breath?"

I can see why that might be a clue...
