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

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. -
