Summary

Story at-a-glance

Atrial fibrillation (AFib) is typically linked to cardiovascular risk factors like hypertension and aging, but evidence suggests chronic oral infections also play a direct role in its development
New research links Porphyromonas gingivalis, the key bacterium in gum disease, to heart scarring and arrhythmias. Findings show it travels to the heart and interferes with electrical signaling
In animal models, P. gingivalis exposure increased AFib risk, while human heart tissue confirmed higher bacterial load and damage in patients with severe gum disease
A 14-year study of 1.25 million people found chronic gum disease increased AFib risk by 4%, while recovery lowered risk to nearly the same level as gum-healthy individuals
To improve your gum health, make sure to brush and floss daily, try oil pulling, eat a whole-food diet, manage your stress levels, and get regular cleanings from a biological dentist trained in systemic oral care

0:00.0	Did you know that the bacteria quietly hiding in your gums could slip into your bloodstream,
0:05.0	lodge in your heart, and tilt its rhythm offbeat?
0:08.0	Welcome to Dr. Mercola's cellular wisdom.
0:11.0	Stay informed with quick, easy-to-listen summaries of our latest articles, perfect for when you're on the go.

0:22.7	Hello, and welcome to Dr. Mercola's cellular wisdom. I'm Ethan Foster, and alongside me is co-host Alara Sky.
0:31.0	Today we'll show you why caring for your mouth could be the missing link in protecting your heartbeat.
0:36.1	That connection may sound bold, yet the numbers deserve
0:38.9	attention. Between 2010 and 2019, global cases of atrial fibrillation nearly doubled from 33.5 million
0:47.7	to almost 60 million, while gum inflammation, especially in adults over 30, remains rampant.
0:55.0	These parallel trends suggest that what happens above your neckline can resonate far deeper than you imagine.
1:01.0	Traditional risk models highlight aging, hypertension, and metabolic disorders,
1:07.0	but researchers at Hiroshima University suspected a different culprit lurking under dental plaque.
1:12.6	They zeroed in on porphyrimonus gingivalis, the dominant bacterium in chronic period in titus,
1:19.6	and asked whether its repeated presence could scar cardiac tissue, scramble electrical signals,
1:25.6	and ultimately set the stage for atrial fibrillation.
1:29.3	Porphyromonis gingivalis prospers in oxygen-poor gum pockets,
1:33.7	dismantling connective tissue with potent enzymes.
1:36.7	The researchers followed the microbes' journey after it breached the gum barrier,
1:40.6	curious whether it would simply drift in circulation,
1:43.5	or secure a foothold in the left atrium,
1:46.1	the exact chamber responsible for coordinating a steady, timely heartbeat.
