“When I took my second Bristle test six months later, my jaw dropped. I haven’t had to have any work done at the dentist since I started down this new path, just cleanings! It’s unbelievable!! I honestly can’t thank Bristle enough.”

“If you make one investment in your health this entire year, let this be it. 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.”

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.
