Struggling with chronic halitosis? 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.

It was extremely easy to send in the sample and I received my results quickly. My coach reviewed my results in detail with me, offering up her suggestions as we went and choosing items that fit within my lifestyle. I’m so happy to have stumbled across Bristle and can’t recommend it enough to others!

Bristle goes that extra step to provide actionable advice that will help you improve your oral health. You don’t want to just know what’s causing you to develop cavities or tooth decay. You want to know exactly what you can do to turn that around, and Bristle provides that, and more, for you.

Chase Stevens Independent Reviewer

Chronic bad breath has been bane of my life for years and I've had no idea why! Bristle was the first test to identify what was causing it and give me actionable steps I can take to fix it. The coaching session was incredibly helpful for answering my questions and tailoring my care plan to my needs.
