VSL:SCIENCE // Meet the Kiss-o-Meter

The trouble with bad breath is that the people closest to it can’t smell it. It’s up to us to tell (or not tell) them. And either way, we lose. Now, just in time for Valentine’s Day, we’ve found a product that does the job for us.

The Kiss-o-Meter detects volatile sulfurous compounds released by the bacteria that feast on food particles trapped between our teeth. (Brushing, flossing, and tongue scraping help, but there’s no fail-safe way to fight halitosis.) So breathe into this $30 device, wait a few seconds, and you’ll know whether there’s something your friends aren’t telling you: If only one out of five hearts lights up, it’s definitely time for an Altoid.
