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 and provide one-on-one coaching with one of our oral health experts to review your results.
