Oral health is often treated as a separate issue from chronic disease, but growing evidence suggests the two are more deeply connected than many realize. The mouth is the entry point to both the digestive and respiratory tracts, and poor dental hygiene can contribute to or worsen several chronic conditions—many of which may begin with the hidden health risks in your mouth.
We asked dental professionals: “Have you had any notable observations or correlations between dental hygiene and chronic disease?”
Their firsthand insights align with findings from medical organizations such as the CDC and American Heart Association, underscoring how brushing, flossing, and regular dental visits can do more than just keep your smile healthy—they can help uncover and prevent the hidden health risks in your mouth that affect your whole body.
Here are their insights:

Prioritize Oral Hygiene For Overall Health
Dr. Greg R. Diamond, Periodontist and Owner of NY Implant Dentistry, NY Implant Dentistry
“In my experience, there’s a strong connection between dental hygiene and chronic diseases. Poor oral care increases the risk of conditions such as heart disease, diabetes, and even lung problems. The mouth is a direct pathway to the rest of the body, so if there’s a buildup of harmful bacteria from not brushing or flossing properly, it can spread and cause issues elsewhere.”
“As a periodontist, I’ve seen that patients who keep up with regular dental visits and practice good oral hygiene tend to have better overall health. Simple habits like brushing, flossing, and getting regular cleanings can help prevent gum disease, which in turn can lower the risk of more serious health issues.”
“For people with chronic conditions like diabetes, gum disease can often be worse, and it can make their other health problems harder to manage. This is why it’s so important for dental professionals to work with other healthcare providers to help patients understand how their oral health affects their entire body.”

Understand the Link Between Oral Health and Disease
Sandip Sachar, Dentist, Sachar Dental
“I have observed that there’s a strong connection between dental hygiene and cardiovascular disease. Conditions like gingivitis and periodontitis, which are part of periodontal disease, cause inflammation in the tissues surrounding the teeth. This inflammation and the associated bacteria can enter the bloodstream, leading to the formation of arterial plaque, which contributes to heart disease.”
“I have also noticed a well-documented connection between dental hygiene and diabetes. Poor oral health, particularly periodontal disease, can make it more challenging for individuals with diabetes to control their blood sugar levels. Conversely, high blood sugar levels can worsen periodontal disease, creating a vicious cycle.”
“Poor dental hygiene is also linked to respiratory diseases. Bacteria from the mouth can be inhaled into the lungs, leading to respiratory infections such as pneumonia. This is particularly concerning for individuals with COPD or other chronic respiratory conditions, as they are more vulnerable to infections.”

📌 Research published in the Journal of Periodontology found that respiratory pathogens can colonize in dental plaque, leading to respiratory infections, particularly in elderly or immunocompromised individuals.
Recognize the Impact of Oral Hygiene
Evan McCarthy, President and CEO, SportingSmiles
“As a dental lab owner, I’ve seen firsthand how dental hygiene can have a big impact on overall health, especially when it comes to chronic diseases. Poor dental hygiene can lead to gum disease, which has been linked to problems like heart disease, diabetes, and even strokes. When people don’t take care of their teeth, harmful bacteria can enter the bloodstream and affect other parts of the body.”
“I’ve noticed that patients who take better care of their teeth tend to have fewer health issues in the long run. This connection between oral health and chronic disease is why it’s so important to practice good dental care every day.”

Final Thoughts: Don’t Ignore the Hidden Health Risks in Your Mouth
Poor dental hygiene isn’t just a cosmetic or localized issue, it can reflect and even influence your systemic health. As these dental professionals and medical sources confirm, there is a significant correlation between oral hygiene and chronic diseases such as diabetes, heart disease, respiratory illness, and more.
Taking small daily steps like brushing, flossing, and scheduling regular cleanings doesn’t just protect your teeth—it supports your whole body.
