Struggling with oral health? You’re not alone.

We know because we’ve been there. Dealing with oral disease 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 oral health

Specific bacteria in your mouth release byproducts that cause bad breath, gum inflammation, and more. We measure the levels of these bacteria, give you a full report, and provide one-on-one coaching with one of our oral health experts to review your results.

By identifying the root cause of your symptoms and understanding your experience and preferences, we'll figure out which products, diet, and hygiene routines will work best for you.
