Swiss Biologic Dentistry Introduces Bristle Oral Microbiome Testing in Phoenix

Swiss Biologic Dentistry is introducing Bristle saliva testing to help patients identify oral bacteria linked to cavities, gum disease, bad breath, and overall health.

PHOENIX, Ariz. — Most people understand the gut has a microbiome, but the mouth has one, too, and it may be one of the body’s most overlooked indicators of overall health. Swiss Biologic Dentistry is bringing that connection into clearer focus with the Bristle Oral Microbiome Health Test, a saliva-based test that identifies the bacteria and fungi living in a patient’s mouth and helps show how that microbial balance may affect health beyond the smile.

Using DNA sequencing, the Bristle test profiles more than 800 species of bacteria and fungi, showing which organisms are present, which are at healthy levels, and which may be overgrown or depleted in ways that contribute to disease. The timing is significant: Nearly half of U.S. adults age 30 and older have some form of periodontal disease, according to the CDC. By identifying microbial imbalances beneath the surface, the test helps provide earlier insight into the root causes of cavities, gum disease, inflammation, and recession before those issues become visible during a traditional dental exam.

“At Swiss Biologic, we look at the mouth as part of the whole body, not something separate from it,” said Matt Ellingson, CEO of Swiss Biologic Dentistry. “The mouth is where digestion begins, and it can tell us a lot about what may be happening elsewhere in the body. Saliva testing helps patients see that connection more clearly, so we can make care more personal, more precise, and more rooted in their own biology.”

In simple terms, oral microbiome testing does for the mouth what many patients already understand through gut health. The goal is not to kill all bacteria. The goal is to cultivate the right balance. Some microbes help protect the mouth, while others are associated with cavities, gum disease, chronic bad breath, inflammation, and oral fungal issues. Because the mouth is the start of the digestive tract, imbalances there can also ripple downstream and affect the gut environment.

For Swiss Biologic Dentistry, Bristle testing also helps challenge one of the most common myths in oral care: that harsher means healthier. Alcohol-based mouthwashes, aggressive rinses, colloidal silver, and some antibacterial products may wipe out beneficial bacteria along with harmful ones, potentially making the oral environment more vulnerable over time.

“A burning mouthwash does not necessarily mean a healthier mouth,” Ellingson said. “For many patients, that is a major mindset shift. The question is not how aggressively we can sterilize the mouth, but how intelligently we can support a balanced, resilient microbial environment.”

Bristle saliva testing can help Swiss Biologic Dentistry personalize care by identifying the microbial root causes of cavities, gum disease, bad breath, chronic oral inflammation, or a combination of concerns. It can be especially useful for patients who keep getting cavities despite good home care, patients with a history of gum disease, patients managing systemic conditions such as heart disease, diabetes, or autoimmune disorders, and patients preparing for extractions, implants, or other surgical procedures.

Key benefits of Bristle saliva testing at Swiss Biologic Dentistry include:

Microbial insight: The test identifies bacteria and fungi present in the mouth and shows whether they are at healthy, elevated, or depleted levels.

Earlier detection: Saliva testing can reveal microbial imbalances before visible damage appears during a traditional dental exam.

Personalized treatment planning: Results help guide product recommendations, home care routines, periodontal therapy, and clinical treatment based on each patient’s specific microbial profile.
Cavity and gum disease clarity: The test can help determine whether a patient is more prone to tooth decay, periodontal disease, or both.

Surgical planning: For patients preparing for extractions, implants, or other procedures, microbiome testing may help identify microbial risk factors that could affect healing.

Baseline tracking: For healthy patients, testing creates a personal benchmark that can be compared over time if medications, diet, stress, illness, or other changes affect oral health, similar to annual bloodwork.

“What patients see on a report can completely change the conversation,” said Dr. Alexis Yip, DMD, of Swiss Biologic Dentistry. “Gum disease is often painless in the early stages, so it can be hard for patients to understand why deeper treatment is necessary when they feel fine. When they can see their own microbial profile, the information becomes personal, objective, and much easier to act on.”

Swiss Biologic Dentistry’s use of Bristle testing aligns with its broader philosophy that dentistry should support the body’s natural systems rather than work against them. Research continues to strengthen the connection between oral dysbiosis, or microbial imbalance, and systemic conditions including cardiovascular disease, type 2 diabetes, rheumatoid arthritis, Alzheimer’s disease, and chronic inflammation.

“The most important thing we want patients to understand is that what happens in the mouth does not stay in the mouth,” Ellingson added. “Oral bacteria and inflammation can influence the entire body. When patients understand that, they stop thinking about dentistry as isolated repair work and start seeing it as part of their long-term health strategy.”

Bristle saliva testing is now available at Swiss Biologic Dentistry for patients seeking a deeper, more personalized understanding of their oral health. The practice is located at 3611 N. 7th St., Phoenix, AZ 85014. Learn more at swissbiologic.com.
