Key Risk Factors for Mouth Cancer You Need to Know

7. Poor Oral Hygiene & Ill-Fitting Dentures

Surprisingly, poor oral hygiene and chronically irritating oral conditions can contribute to mouth cancer risk. Chronic inflammation from neglected dental health (e.g., gum disease, untreated cavities) creates a hostile environment that can promote cellular changes. Similarly, ill-fitting dentures or broken teeth that consistently rub and cause chronic irritation to the mouth's soft tissues can, over extended periods, lead to precancerous lesions. These chronic physical traumas, coupled with inflammation, may provide fertile ground for abnormal cell development. Regular dental check-ups and proper denture care are essential not just for comfort, but for cancer prevention.

8. Nutritional Deficiencies: The Body's Vulnerability

A diet lacking essential vitamins and minerals, particularly Vitamins A, C, E, and certain B vitamins (like folate), can weaken the mouth's natural defenses against cancer. These nutrients are crucial for maintaining healthy oral tissue and providing antioxidant protection, which helps prevent cellular damage and supports DNA repair. When the body is deficient, oral cells become more vulnerable to carcinogens and less able to correct DNA errors. Ensuring a balanced diet rich in fruits, vegetables, and whole grains provides your body with the necessary tools to protect itself from cellular damage and reduce mouth cancer risk.
