Health experts are drawing renewed attention to the importance of daily oral hygiene as oral cancer rates continue to increase across the United States, with research indicating that consistent dental care may support risk reduction and improve early detection outcomes.
The American Cancer Society estimates that approximately 60,000 Americans will be diagnosed with oral cancer this year. The disease, which can affect the tongue, gums, tonsils, mouth, and throat, has shown a steady upward trend over the past two decades, prompting increased concern among dental and medical professionals.
While oral cancer cannot always be prevented, experts say strong oral hygiene habits may help reduce contributing risk factors. “Maintaining excellent oral hygiene is one of the best preventive steps people can take,” said Lilya Horowitz, D.D.S., AAACD, who emphasized routine brushing twice a day, daily flossing, and regular dental checkups as foundational practices.
Dental professionals explain that these habits help control plaque accumulation, reduce inflammation, and slow the progression of gum disease, all of which are associated with long-term damage to oral tissues. “When harmful bacteria and plaque accumulate, they create chronic inflammation that can damage oral tissues over time,” said Roumiana Tzvetkova, D.D.S., D.M.D. “Reducing that buildup helps maintain a healthier oral environment and may lower the risk of serious conditions, including oral cancer.”
Untreated periodontal disease can progress into periodontitis, a severe infection affecting the gums and bone structure supporting the teeth. Research suggests that bacteria associated with gum disease may contribute to inflammatory responses and DNA damage that are linked to oral cancer development.
Experts also highlight the importance of the oral microbiome, the complex ecosystem of bacteria in the mouth that plays a key role in overall oral health. “The mouth is a living ecosystem,” said Arthur Glosman, D.D.S. “When harmful bacteria dominate, chronic inflammation can make it easier for abnormal cells to develop.”
Flossing is considered particularly important because toothbrushes cannot effectively clean between teeth, where plaque commonly builds up. Studies suggest that regular flossing may help maintain a more balanced oral microbiome and support healthier gum tissue.
Routine dental visits remain essential for both prevention and early detection. During examinations, dentists assess not only teeth but also soft tissues in the mouth, checking for early warning signs such as sores, lumps, or discoloration that may indicate oral cancer. “I am not just looking at teeth,” Glosman said. “During every exam, I carefully evaluate all of the soft tissues in the mouth.”
The American Dental Association recommends that most adults visit a dentist once or twice a year, although individuals with elevated risk factors may require more frequent care. In addition to oral hygiene, health experts advise lifestyle measures such as avoiding tobacco products including vaping, limiting alcohol consumption, eating a diet rich in fruits and vegetables, protecting lips from ultraviolet exposure, and receiving the HPV vaccine when eligible.
While no single strategy can fully prevent oral cancer, health professionals emphasize that combining consistent oral hygiene with healthy lifestyle choices may significantly reduce risk and improve the chances of early detection and effective treatment.
