Biological Dentistry: Could the Root Cause of Disease Be in Your Mouth?

A biological dentist takes a holistic approach to oral health—recognizing that the mouth is deeply connected to the rest of the body. Unlike conventional dentistry, this field understands that what’s happening in your teeth and gums can influence everything from your heart to your immune system.

🦷 Why Root Canals Can Be a Problem

When a root canal is performed, the blood supply and nerves to the tooth are severed—leaving behind dead tissue in a living body. The body can no longer deliver immune support to the area. While the tooth is “saved,” it’s now a sealed-off chamber—a perfect, oxygen-deprived environment for harmful bacteria.

This bacteria festers silently, and the immune system, unable to reach it, is left to fight a constant, hidden infection. Nowhere else in the body would we leave dead tissue in place. So why in the mouth?

Infected teeth have the potential to cause serious systemic consequences.
Here’s a shocking fact:
97% of women with breast cancer who also had a root canal had it on the same side as their cancer.

What the Experts Say

“The vast majority of chronic degenerative diseases begin with infections/toxins in the mouth, and it’s only until those are addressed that you’re going to have any clear and positive response to your disease.”
— Dr. Thomas E. Levy, MD, author of The Toxic Tooth

It’s not just root canals. Other dental issues like cavitations, extraction sites (especially wisdom teeth), and old dental work can also be sources of chronic infection.

To truly rule out hidden oral infections, you need a 3D Cone Beam scan. Regular dental X-rays can miss these issues entirely.

Our Story: A Hidden Infection, A Wake-Up Call

At just 33 years old, my husband Zach was diagnosed with stage 3 colorectal cancer. In our search for root causes, we left no stone unturned.

We found a biological dentist who performed a 3D Cone Beam scan—and discovered two infected root-canaled teeth. Before extracting them, we ran a MyPerioPath test, which detects 11 harmful oral pathogens. Zach tested positive for 3 high-risk bacteria:

• Fusobacterium nucleatum/periodonticum

• Prevotella intermedia

• Peptostreptococcus (Micromonas) micros

⚠️ Fusobacterium has been found in colorectal tumors and is known to spread cancer to the lymph nodes.

“Do you mean to tell me the answer has been under my nose this whole time?”
— Zach Labie

Yes, in Zach’s case, one of the infections was literally in a tooth just under his nose.

Take Action

If you’re battling a chronic illness—especially cancer—start by checking your mouth. Here’s what we recommend:

1. Find a certified biological dentist (look for IAOMT and SMART certifications).

2. Get a 3D Cone Beam scan to check for cavitations or hidden infections.

3. Run a MyPerioPath test to assess oral pathogens and their disease risk.
