Flossing: The Tiny Habit That Could Save Your Life

We all know flossing keeps our teeth and gums healthy — but did you know it might also protect your heart and brain?

A new study from the American Heart Association found that people who floss regularly may have a lower risk of stroke, blood clots, and irregular heartbeats (atrial fibrillation).

Here’s what the research revealed:

• 22% lower risk of ischemic stroke (the most common type caused by blocked blood flow)

• 44% lower risk of cardioembolic stroke (a clot that travels from the heart to the brain)

• 12% lower risk of atrial fibrillation (irregular heartbeat)

Pretty amazing for something that takes less than two minutes a day!

So, how does flossing affect your heart and brain?

It all comes down to bacteria and inflammation.
When you skip flossing, bacteria can sneak below your gumline and enter your bloodstream.
Once inside, these bacteria can trigger inflammation in your blood vessels — making clots more likely to form.

Those clots can then block blood flow to your brain (causing a stroke) or interfere with your heart’s rhythm.

In short:
Gum bacteria → Inflammation → Higher risk of clots → Stroke or Afib

The good news? Even a little flossing helps.

The study showed that even flossing once a week made a noticeable difference. Of course, daily is best — but every bit counts.

So next time your dentist reminds you to floss, remember: they’re not just thinking about your teeth — they’re thinking about your heart and brain, too.

Protect your smile. Protect your health.
Floss daily if you can — your future self will thank you.
