Your mouth is full of bacteria. But here’s the twist: some are actually good for you.
Think of your mouth like a tiny ecosystem. You have “good guys” that help keep things balanced, and bacteria that can cause trouble when they get out of control.
One bacteria researchers are watching closely is Fusobacterium nucleatum.
It normally lives in the mouth, but higher levels have been found with gum disease and colorectal cancer. New research suggests this bacterium may trigger inflammation that helps tumors grow, at least in mice.
Does this mean your mouth bacteria causes colon cancer?
No. We’re not there yet. More research is needed.
But it raises a big question:
Could the bacteria living in our mouths affect the rest of our bodies?
Scientists are starting to think the answer may be yes.
So how do you keep the good guys happy?
Brush twice a day.
Clean between your teeth every day.
Take care of your gums.
Keep your regular dental visits.
The future of may look at the mouth in a whole new way.
Your mouth isn’t just where your smile lives. It’s an ecosystem, and keeping it healthy may matter more than we once thought.
