🦷 What if your next dental appointment could reveal far more than just a cavity?
Most of us grew up thinking dentistry was about teeth. Clean them, fill them, fix them. But what if the health of your mouth is actually a window into your heart, your brain, your immune system — and your whole body?
In this eye-opening episode of Your Grey Matters, host Neil Silvert sits down with Carol Wells — a dental hygienist with nearly 50 years of experience and a pioneer in biological dental hygiene — to explore what the mouth-body connection really means, and what most dental professionals still aren’t talking about.
Carol pulls no punches: from the inflammation cascade that links gum disease to diabetes and Alzheimer’s, to the surprising controversies around root canals, mercury amalgam fillings, and fluoride in your water. This is the kind of conversation most people never get to have — and it could change the way you think about your health forever.
🔍 In this episode, you’ll discover:
Why bleeding gums are NEVER normal — and what they’re really warning you about
How oral bacteria can enter your bloodstream and affect your heart, gut, and brain
The phase contrast microscope: a chairside tool that can see your bacteria live
Root canals — what your dentist may not have explained about “when” they fail
Mercury amalgam fillings: why biological dentists use hazmat suits to remove them
Fluoride: neurotoxin or cavity fighter? What the research is actually saying
Thermography: the inflammation-detection tool changing preventive health
Why physicians ignore the mouth — and dentists ignore the body — and why that has to change
💬 “If you have a sliver in your finger and it gets infected, your whole body tells you. That same inflammation cascade happens in your mouth — you just don’t feel it the same way.” — Carol Wells
This episode isn’t about scaring you away from your dentist. It’s about empowering you to ask better questions, understand what’s really happening in your mouth, and take ownership of your health from the inside out.
