Scientists develop tool to gauge bad breath

Know someone whose breath could peel the paint off a wall?

Then consider the OkaytoKiss - a device that gauges bad breath that was recently invented by scientists at Tel Aviv University.

The pocket-sized breath test measures malodorous bacteria in your mouth. A blue result suggests you need a toothbrush. But if it’s clear, you’re okay-to-kiss.

Until recently, scientists believed that only one population of bacteria (the Gram-negative ones) break down the proteins in the mouth that produce foul odor. But Professor Mel Rosenberg and Dr. Nir Sterer have discovered another kind of bacteria that also foster bad breath.
