The tech behind the test

The world’s first and most advanced oral health test to help you easily and effectively improve your health.

Learn all about it 👇

Good health starts with a healthy mouth

But we don't treat it like that

X-rays & checkups only catch existing disease

The tools we use only catch disease when it's already there, not when it can be prevented.

We get: expensive & painful treatments

We pay $1000 per year out of pocket on dental care for root canals, fillings and other procedures!

We never address the root-cause of our issue

Reactive care means we'll be back in the dental chair again - and again, and again....

This is the way it should be


Identify the root-cause of conditions and understand your risk before they become problems


Take the guesswork out of your oral care with targeted recommendations that make an immediate impact.

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

👅 Meet your oral microbiome - the bacteria, fungi and viruses that live in your mouth.

A healthy oral microbiome is the foundation of good oral health

Some microbes are good and keep your mouth healthy. Other microbes are harmful. Too many or too much of the bad microbes leads to conditions like bad breath, tooth decay and gum disease - the result of an imbalanced oral microbiome. 

Making small changes to your diet, hygiene and oral products based on your unique biology helps you achieve better oral health through a balanced oral microbiome!

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

❤️ Your mouth is the gateway to your body and the mirror of your health

Your oral microbiome impacts your heart, brain, digestive and immune health 

Harmful bacteria in your mouth can travel to other parts of your body and cause damage. Poor oral health is associated with increased risk of conditions including cardiovascular disease, diabetes and Alzheimer's. 

Improving your oral health through your oral microbiome is one way to mitigate your risk for these conditions and improve your overall health. 

🦠 There are thousands of microbes associated with your oral microbiome. 

We developed the world's first oral microbiome test to give you insights into your oral health

We use shotgun metagenomic sequencing to identify all of the microbes in your mouth and data from thousands of samples to provide insights into your health - all from a single saliva sample.

🦷 Good oral health takes more than brushing and flossing

We retrain your biology to help you improve your oral health

We go way beyond the same advice you constantly hear and take a holistic approach to improving oral health at the biological level. Your custom recommendations are researched, vetted and curated by our team.

Hear from dentists using Bristle

“Since adding Bristle testing to my practice and my Oral Microbiome Reset Program, I have seen tremendous results. Patients have more information and data, which can be very motivating, and we now have metrics to determine if our treatments and protocols are actually shifting things toward health and balance in their children. I am so excited to see where Oral Microbiome research is headed, and Bristle is certainly paving the way toward better patient outcomes and understanding root cause issues within our patients.”

Dr. Staci Whitman, DDS | Pediatric Dentist

NoPo Kids Dentistry

“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.”

Dr. Jen Chiang, DDS | General Dentist

“Most of my patients are timid when talking about bad breath. The Bristle Oral Health Test has helped patients identify the underlying issue of their symptoms and devise treatment solutions that will work best for them.”

Dr. Chris Strandburg, DDS | General Dentist

Vision Dental

“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.”

Dr. Mark Burhenne, DDS | General and Family Dentist

I'm thrilled to have discovered them.

I found Bristle while taking steps to fix some recurring gut issues, I wasn't aware of how connected your mouth flora and gut flora are until I began following the Bristle regiment and now my overall digestive and oral health are better than I even thought possible.

 I can't believe this actually worked!

Chronic bad breath has been bane of my life for years and I've had no idea why! Bristle was the first test to identify what was causing it and give me actionable steps I can take to fix it. The coaching session was incredibly helpful for answering my questions and tailoring my care plan to my needs.


Wisdom is so helpful

So nice to get this deep healing level of help and advice and guidance . Their wisdom is so helpful and everyone is so efficient.

Kara L.

So easy with great results!

It was extremely easy to send in the sample and I received my results quickly. My coach reviewed my results in detail with me, offering up her suggestions as we went and choosing items that fit within my lifestyle. Im so happy to have stumbled across Bristle and cant recommend it enough to others!

Bristle is the full package

Bristle goes that extra step to provide actionable advice that will help you improve your oral health. You dont want to just know whats causing you to develop cavities or tooth decay. You want to know exactly what you can do to turn that around, and Bristle provides that, and more, for you.


Exciting company

It's an exciting company in terms of how it can help individuals but also how it can use big data and science to learn about oral health, find patterns, and solve problems.


Uses science to fix it for good

I need to get to the bottom of my halitosis and this is the only company that seems to be using science to fix it for good


Giving me answers

So far, it is giving me answers to a long awaited dilemma as to why I have had halitosis for all these years
