“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… no more bad breath!
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!”

Oral health isn’t rocket science - it’s biology
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.
