Struggling with bad breath?

There is no single cure for bad breath, but there is a better way to treat it than carrying around mints, mouthwash, and gum in your pocket 24/7. Bristle takes the guesswork out of bad breath to help you get your confidence back.

Root-cause care for bad breath

Specific bacteria in your mouth or throat release byproducts that cause bad breath. Our test identifies and measures these bacteria to help you understand exactly what's causing it.
