Oral health is more than just a beautiful smile — it can be a matter of life.
A recent study published in The Lancet Regional Health (2025) highlights a critical warning: harmful bacteria thriving in an unclean mouth can trigger chronic inflammation, a condition strongly associated with an increased risk of cancer — particularly cancers of the head and neck.

Researchers explain that pathogenic oral bacteria such as Porphyromonas gingivalis and Prevotella intermedia do not remain confined to the gums. These microorganisms can enter the bloodstream, affect distant tissues, and create a biological environment that favors the initiation and progression of cancer cells.

The findings are alarming: individuals with periodontal disease have more than double the risk of developing oral cancer compared to those with healthy gums. Strong associations were also observed between poor oral hygiene and cancers of the digestive system, including the stomach, esophagus, and colon.

The message is clear: neglecting daily oral hygiene and routine dental check-ups does not only lead to cavities or bad breath — it may silently increase the risk of life-threatening diseases.

The good news? This risk is largely preventable.
Brushing twice a day, flossing daily, professional dental cleanings, and early treatment of gingivitis or periodontitis significantly reduce inflammation and protect overall health.

Oral care is no longer just about your smile — it’s about your life.
