Periodontitis linked to increased risks of cancer, kidney disease, and respiratory issues
Scientific reviews and clinical studies have identified significant associations between periodontitis—chronic gum inflammation—and several serious health conditions.
Research involving approximately 460,000 participants indicates that periodontitis is linked to an 18% higher risk of breast cancer and a 17% higher risk of prostate cancer. While these increases are considered modest in population health studies, the consistency across independent research is notable.
A study conducted at a university hospital in Porto Alegre, Brazil, found that patients with severe periodontitis have a 2.8 times higher chance of being in stage 4 chronic kidney disease and a 3.4 times higher chance of being in stage 5, the most advanced stage, compared to those without severe gum disease.
Furthermore, a 2023 review published in the Journal of Clinical Periodontology found that periodontitis is associated with a 28% increased risk of chronic obstructive pulmonary disease (COPD) and a 65% increased risk of obstructive sleep apnea. These respiratory links may be driven by microaspiration, where bacteria-laden saliva enters the lungs.
