Bristle helps you measure, understand, and improve your oral health. Our mouths are the gateways to our bodies and play a critical role in our overall health. Oral disease like cavities and gum disease are tied to increased risk for conditions including Alzheimer's, diabetes, and heart disease. There has not been a way to measure oral health. Dental care today revolves around diagnosing and treating oral disease but does little in the way of prevention and whole-body health. Bristle analyzes the oral microbiome - the makeup of bacteria, fungi, and viruses in saliva - to measure oral health status. Some of these microbes are helpful, and contribute to good oral health while lowering our risk for disease. Other microbes are harmful, directly or indirectly leading to oral and systemic disease. Our test provides you with direct insight into your oral health and risk factors for disease. Based on other factors including your medical history, diet, and hygiene, we pair you with personalized recommendations focused on repairing and maintaining balance in your oral microbiome. We believe that improving oral health is a fundamental step towards improving overall health - and we'd like to help you get here.
