Dentists have long suspected a link between oral hygiene and cardiovascular health.
Today, research confirms that the connection is real, and more important than once believed.
Our mouths aren’t isolated from the rest of the body. They act as gateways where bacteria and toxins can enter the bloodstream, setting off inflammation that affects far more than teeth and gums.
One of the most common problems is periodontitis, a chronic gum infection that damages the tissue supporting your teeth.

According to the U.S. Centers for Disease Control and Prevention (CDC), about four in ten adults over 30 are affected.
When gums become inflamed, they bleed easily, and teeth may loosen, but the real danger lies in the systemic inflammation that can spread throughout the body.
This inflammation may harden arteries, disrupt blood flow, and raise the risk of heart disease.
What the research shows
A study published in the European Heart Journal found that people with severe gum disease had thicker carotid arteries, an early warning sign of cardiovascular damage.

Researchers believe that bacteria from infected gums can enter the bloodstream and harm the delicate lining of blood vessels.
In a separate clinical trial led by scientists at King’s College London, 135 adults with gum disease were divided into two groups: one received routine cleaning, while the other underwent intensive periodontal treatment below the gum line.
Two years later, those who had received the intensive care showed thinner arteries, improved vascular function, and lower levels of inflammation.
According to the researchers, these results suggest that maintaining good oral hygiene could directly contribute to better heart health.

What your gums might be telling you
Gum disease doesn’t develop overnight. It usually begins as mild gingivitis, red, swollen, or bleeding gums, and gradually worsens if left untreated.
Persistent bad breath, pain while chewing, or sensitive gums are also warning signs that bacteria might already be doing more harm than you realize.
Dentists recommend combining daily brushing with flossing, interdental brushes, or mouth rinses to clean the areas your toothbrush can’t reach.
Regular dental checkups can catch early symptoms before they become serious.
