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.

  • As a biological dentist, Bristle has significantly enhanced our diagnostic capabilities, providing valuable insights beyond traditional assessments. My patients appreciate the detailed information, and I'm consistently impressed by the efficiency of the Bristle process and their excellent customer support. I highly recommend Bristle for any dental practice seeking to elevate patient care.

    Sharon Dickerson, DDS

  • 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.

    Jen Chiang, DDS

  • The Bristle test has shifted my treatment mindset from "kill mode" to "build and balance mode." Customizing patient treatment at a microbial level is the future of comprehensive dental care. Patients are becoming increasingly aware of the oral systemic connection and having a clear picture of their risk for disease helps us collaborate to create a pathway to health.

    Monica, RDH

  • It's like unlocking a key to a puzzle. The data is easy to understand an allows us to take a deep dive into the underlying root cause of issues that have confounded us in the past. Everything makes sense. Anyone who cares about their health and connecting the dots to the oral systemic connection needs to have the Bristle test done.

    Janet, RDH

  • No other salivary test is as comprehensive as Bristle. It allows me to share a broad view of positive and negative factors and dive deep when I need to. Detecting all microbes, including candida, is important for me to share with patients. I love that the report is provided to our office and to the patient. It has been very helpful to share with our patient's referring providers.

"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.”
