Bristle is the first and only comprehensive salivary test to analyze the entire oral microbiome, including all 700+ unique species of bacteria found in the mouth identifying the root cause of bad breath.

Specific bacteria in your mouth or throat release byproducts that cause bad breath.

Our test identifies and measures these bacteria to help you understand exactly what's causing it.

Receive data-backed diet, hygiene and product recommendations based on your results plus 1:1 coaching with our certified team for questions or support along the way.

Bristle takes the guesswork out of bad breath to help you feel confident again

Meet Olivia

“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…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!” - Olivia, 35

How it works

  • Take your saliva test

    Get an in-depth report detailing the bacteria in your mouth and its impact to your health.

  • Get your care plan

    Receive personalized oral care and diet recommendations based on your results.

  • Meet your coach

    Review your program and access ongoing support through our team of hygienists.

  • Measure your progress

    Watch your results measurably improve throughout the year by testing every 3 or 6 months.

  • Get started with our at-home saliva test

    Dental checkups only look for existing problems like cavities or gum disease. Instead of looking for symptoms to treat, Bristle analyzes your saliva to identify the bacteria in your mouth that cause those symptoms. By detecting these bacteria at the earliest stages we can help you prevent the onset of disease.

    Our test was developed from the ground-up using clinical research and your results are compared against thousands of other samples.

    Turn insights into action with a personalized program

Hear from dentists using Bristle

  • “Since adding Bristle testing to my practice and my Oral Microbiome Reset Program, I have seen tremendous results. Patients have more information and data, which can be very motivating, and we now have metrics to determine if our treatments and protocols are actually shifting things toward health and balance in their children. I am so excited to see where Oral Microbiome research is headed, and Bristle is certainly paving the way toward better patient outcomes and understanding root cause issues within our patients.”

  • “Bristle is the future of oral health care. With a simple noninvasive saliva test, we can assess patients' periodontal and caries risk rather than just waiting for bone loss and decay. Why wait for a heart attack or stroke to treat cardiovascular diseases if you see elevated biomarkers in blood tests? The same should be true in the future for dental care.”

  • “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.”
