Struggling with bad breath?
You're not alone.

Over 50 million people in the United States suffer from chronic bad breath. 90% of bad breath is caused by specific types of bacteria in your mouth that produce volatile sulfur compounds (VSCs). Bristle identifies these bacteria and develops a custom care plan to help you eliminate them.

Langford

I'm thrilled to have discovered them.

I found Bristle while taking steps to fix some recurring gut issues, I wasn't aware of how connected your mouth flora and gut flora are until I began following the Bristle regiment and now my overall digestive and oral health are better than I even thought possible.

 I can't believe this actually worked!

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.

Kara L.

So easy with great results!

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. Im so happy to have stumbled across Bristle and cant recommend it enough to others!

Bill

Uses science to fix it for good

I need to get to the bottom of my halitosis and this is the only company that seems to be using science to fix it for good

Nicole

Giving me answers

So far, it is giving me answers to a long awaited dilemma as to why I have had halitosis for all these years

“Bristle has been such an incredible resource to help me better understand the source of bad breath and my overall health. I have been struggling to combat bad breath for over a decade and was unable to find a solution. After visits with my dentist, G.I. Specialist, and ENT, I was left feeling lost and helpless. After sending in my sample to Bristle, they provided me with a care plan that finally corrected the problem… no more bad breath!

I also have a better understanding of how my overall health plays such an important part. I am so grateful for Bristle and the positive influence it has made for me!”

Oral health isn’t rocket science - it’s biology

The oral microbiome is the complex ecosystem of bacteria, fungi, and more that lives inside your mouth. Some keep our teeth and gums healthy, while others cause damage and cause conditions like bad breath, tooth decay and gum disease. The latest research has also linked the oral microbiome to conditions like heart disease, Alzheimer’s and diabetes. 

Your oral microbiome is the foundation of your oral health. We help you identify and eliminate the harmful bacteria in your mouth to improve your oral and overall health.
