I couldn't be happier with the results. I’ve been struggling with this issue (not so fresh breath) for so long, and finally, after a few weeks, my breath is fresh, and I feel better overall. It's been a life-changing and positive experience for me.
I had been dealing with bad breath for a while. I took the Bristle test and probiotic, and I noticed a difference immediately, and a week later the significance was even more. Now 2-3 weeks in, I feel like a new person!
I was constantly worried about my breath, but Bristle gave me clear steps to address the root cause. Now I can finally speak up without feeling self-conscious!
The test was so easy and the results were so helpful for me to determine the cause of my bad breath and what I need to do
This test definitely helped me get down to the root cause of my offensive breath that has been haunting me for 3 years now. I found out through this test it was gum line bacteria hiding under my dental bridge. Oh my God I am so relieved!

Take a look at our FAQs
What does the Bristle test look for?
Bristle profiles your complete oral microbiome - the makeup of 700+ bacteria and fungi in your mouth. Our test is the most comprehensive available and identifies all microbes present in your oral microbiome.
Some of these species are beneficial to our health, while others are harmful and can cause conditions like halitosis, tooth decay, gum inflammation, and more. By analyzing the identity and relative abundance of microbes in your saliva, Bristle detects the root cause of oral symptoms and connections to other chronic conditions. We also provide scientifically-backed product, diet, and lifestyle recommendations based on your unique oral microbiome.
How many microbes does Bristle detect?
We offer the most advanced and comprehensive oral microbiome test available. On average we identify 100+ bacterial species per sample. Bristle is also the only test that detects bacteria, fungi and viruses from a single saliva sample.
Can I share my results with my dentist?
Yes! We encourage you to share your results with your dentist and anyone else involved with your health. You can print or share your results directly from your account.
Can I use HSA/FSA for payment?
Bristle tests are eligible for reimbursement by most FSA and HSA plans. Since every plan is different, we advise that you check with your plan to confirm that the Bristle test is eligible. Contact us at support@bristlehealth.com to obtain an itemized receipt.
