Oral health has always been challenging because it is often a guessing game. With testing products finally available to the consumer population, we will see way more successes over failures. People will find the small changes they can make for big wins and even bigger motivation. I couldn't be more excited for Bristle's oral microbiome testing capabilities! I've begged for this technology my entire 30-year dental career! As an oral health coach and dental hygienist I know the power testing and motivation play in the role of healing mouth issues!

Good health starts with a healthy mouth.

The Bristle test can help identify the root cause of symptoms, including:

Chronic bad breath
Gut inflammation
Tooth decay
Receding gums
Inflamed gums
Tongue coating
Weird taste

Struggling with cavities, gum disease, or bad breath? You’re not alone.

We know because we’ve been there. Dealing with oral health issues has left us feeling frustrated, embarrassed, and lost. We’ve turned from doctor to doctor trying to find a diagnosis and solution, so we’ve created a better way.

Address the root cause of oral health conditions.

Specific bacteria in our mouths cause tooth decay, gum inflammation and recession, and bad breath. We measure the levels of these bacteria to provide you a full report on your oral health with recommendations and coaching so you can start improving.

Not one-size-fits-all, one size fits you.

By identifying what’s causing your symptoms and understanding your experience and preferences, we'll figure out which products, diet, and hygiene routines will work best for you. Our oral health specialists will guide you every step of the way.

Cavities and gum disease are the most common diseases on the planet - and largely preventable.

We only see a dentist a few times per year. Only 50% of US adults regularly go!

Oral disease is diagnosed based on the presence and severity of symptoms

Late-stage detection requires invasive and expensive procedures like cavity fillings and root canals
