A new study has identified a surprising but important factor that may increase the risk of chronic kidney disease: poor oral health. Published in the journal BMC Nephrology, the research highlights a strong connection between conditions affecting the mouth and the health of the kidneys.
The study analyzed data from around 150 previous research reports and found consistent evidence linking gum disease and other oral health issues to kidney problems. Experts explain that poor oral hygiene can weaken the immune system, narrow blood vessels, and trigger inflammation throughout the body.
This inflammation is already known to contribute to serious conditions such as Heart Disease and Type 2 Diabetes, but the study shows it also negatively affects kidney function. In fact, people suffering from chronic kidney disease may also experience worsening gum disease due to increased inflammation in the body.
Researchers noted that severe gum disease can accelerate the progression of kidney disorders, making early prevention even more critical. Since millions of people worldwide may have kidney disease without knowing it, maintaining good oral hygiene could play a key role in reducing risk.
Common risk factors for kidney disease include high blood pressure, diabetes, a family history of kidney failure, and age over 60—making regular health and dental checkups especially important.
