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.

"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.”

Frequently asked questions
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.
