When most people think about oral health, they think of teeth, gums, and a bright smile. But research continues to reveal that what happens in your mouth can affect much more than your smile — it can impact your brain and heart health too.
The Mouth–Body Connection
Your mouth is the gateway to your body. The same bacteria that cause gum disease
(periodontal disease) don’t just stay in the mouth — they can enter the bloodstream and trigger inflammation throughout the body. Chronic inflammation has been linked to a wide range of conditions, including heart disease, stroke, and even Alzheimer’s disease.
Gum Disease and Heart Health
Studies show that people with gum disease are almost twice as likely to suffer from heart disease. Bacteria from infected gums can travel through the bloodstream, attach to blood vessel walls, and contribute to the buildup of arterial plaque. This can increase the risk of heart attack and stroke. Maintaining healthy gums helps protect your cardiovascular system as well as your teeth.
Oral Health and Alzheimer’s Disease
Emerging research has found traces of Porphyromonas gingivalis — the bacteria responsible for gum disease — in the brains of Alzheimer’s patients. Scientists believe this bacteria and its toxins may contribute to brain inflammation and accelerate cognitive decline.
While brushing and flossing alone won’t prevent Alzheimer’s, maintaining excellent oral hygiene and treating gum disease early may reduce one of its possible contributing factors.
Prevention Starts with the Mouth
The good news: gum disease is both preventable and treatable.
● Brush at least twice daily and floss once a day.
● Schedule regular professional cleanings and exams.
● Treat early signs of gum disease such as bleeding gums, bad breath, or gum recession.
● Maintain a balanced diet low in processed sugars.
Keeping your mouth healthy supports your heart, brain, and overall well-being.
