  • 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.

  • 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.

“When I took my second Bristle test six months later, my jaw dropped. I haven’t had to have any work done at the dentist since I started down this new path, just cleanings! It’s unbelievable!! I honestly can’t thank Bristle enough.”

“If you make one investment in your health this entire year, let this be it. The mouth is the gateway to your body and oral bacteria have been associated with a higher risk for systemic conditions including Alzheimer’s, diabetes, cardiovascular disease, and poor pregnancy outcomes.

You can’t be healthy without a healthy mouth. And what you don't measure, you cannot manage.”

Good health starts with a healthy mouth

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.
