Identify and treat the root cause of your bad breath

Understand what's causing your bad breath and fix it with coaching and curated products delivered to you.


Struggling with bad breath symptoms? You’re not alone.

We know because we’ve been there. Dealing with halitosis has left us feeling frustrated, self-conscious, embarrassed, and lost. We’ve turned from doctor to doctor trying to find a diagnosis and solution, so we created a better way.

Bristle takes the guesswork out of treating bad breath

Specific bacteria in your mouth release byproducts that cause bad breath symptoms. We measure your levels and give you a full analysis of these bacteria, identify which treatments will work best for you, then provide one-on-one coaching with one of our oral health experts.
