Oral Cancer Patients Need More Dental Care, Study Finds
Older Americans facing oropharyngeal and oral cancers are navigating not only the complexities of their disease but too significant gaps in dental coverage, according to a newly published study. The research, led by Associate Professor Onur Baser at the City University of New York’s School of Public Health, highlights a critical necessitate for dental coverage reform to better support cancer patients and improve their overall treatment outcomes. The findings, published in Cancer Epidemiology, Biomarkers &. Prevention, reveal a disparity between the medical costs associated with these cancers and the utilization of necessary dental care.
The Financial and Health Burden of Oral and Oropharyngeal Cancers
The study examined insurance claims spanning 2013 to 2024, encompassing data from over 100 million commercially insured adults and 7 million Medicare beneficiaries. Researchers tracked the prevalence of these cancers, healthcare spending, and dental care utilization. The data showed a concerning trend: despite experiencing treatment-related oral complications, patients with oropharyngeal and oral cancers received fewer annual dental visits compared to individuals without cancer, a pattern observed in both Medicare and commercial insurance plans.
The economic burden associated with these cancers is substantial. Risk-adjusted annual healthcare costs averaged $22,984 for Medicare patients and $47,542 for those with commercial insurance. These higher costs were largely driven by increased inpatient and outpatient spending compared to those without a cancer diagnosis. This financial strain is compounded by the fact that many patients are simultaneously facing the need for, but lacking access to, adequate dental care.
Disparities in Prevalence and Access to Care
The study also revealed significant disparities in cancer prevalence. The incidence of oropharyngeal and oral cancers reached 396 cases per 100,000 people within the Medicare population – nearly six times higher than among those with commercial insurance. Men exhibited approximately double the prevalence of these cancers compared to women across both insurance groups. These findings underscore the importance of targeted prevention and early detection efforts, particularly for older men enrolled in Medicare.
A key finding was the lower utilization of dental services among cancer patients. Medicare patients with these cancers had slightly fewer dental visits annually (2.79) compared to matched controls without cancer (2.98). A similar trend was observed in commercially insured patients (2.81 vs. 3.20). Cancer patients received fewer periodontal treatments, restorations, and extractions, suggesting a gap in comprehensive oral healthcare for this vulnerable population. What we have is particularly concerning given the well-documented oral side effects associated with cancer treatments like surgery, radiation, and chemotherapy.
The Role of Insurance and Survivorship Care
The authors attribute these gaps in dental care to shortcomings in survivorship care and the design of insurance plans. Traditional Medicare, in particular, lacks comprehensive dental benefits, leaving many older adults with limited access to necessary dental services. This lack of coverage can create significant barriers to care, especially for those already facing the financial and emotional challenges of a cancer diagnosis.
Dr. Baser emphasizes the need for a more integrated approach to cancer care, stating, “Incorporating pretreatment dental evaluations, regular follow-up, and better coordination between oncology and dental providers could reduce complications and improve quality of life for survivors.” The study underscores the importance of recognizing oral health as an integral component of cancer survivorship, particularly for older men on Medicare who often have multiple chronic conditions.
Understanding the Study’s Methodology and Limitations
The research employed a retrospective cohort study design, analyzing a large dataset of insurance claims. This approach allows for the identification of trends and associations, but it’s essential to note that it cannot establish causation. The study demonstrates a correlation between cancer diagnosis and reduced dental care utilization, but it does not prove that the lack of dental care directly impacts cancer outcomes. Other factors, such as patient preferences, geographic location, and access to transportation, may also play a role.
The study’s findings are based on data from 2013-2024. Although this provides a substantial timeframe for analysis, it’s important to consider that healthcare practices and insurance coverage may have evolved during this period. Further research is needed to assess the impact of recent changes in healthcare policy and the adoption of new cancer treatment protocols.
Implications for Policy and Future Research
The findings from Dr. Baser and his colleagues have significant implications for healthcare policy and the future of cancer survivorship care. The study provides compelling evidence for the need to expand dental coverage, particularly for older adults on Medicare. Integrated medical-dental care models, where oncology and dental providers collaborate to deliver coordinated care, could also improve outcomes for cancer patients.
Further research is needed to explore the specific oral health needs of cancer survivors and to evaluate the effectiveness of different interventions aimed at improving access to dental care. Studies could also investigate the cost-effectiveness of integrated care models and the impact of dental care on cancer recurrence and overall survival.

Healey, and Onur Baser, published their work in Cancer Epidemiology, Biomarkers & Prevention, with a DOI of 10.1158/1055-9965.epi-25-1267.
Looking ahead, the conversation around cancer care must broaden to encompass oral health. Ongoing surveillance of dental care utilization among cancer patients, coupled with policy changes that address coverage gaps, will be crucial to ensuring that all individuals affected by these diseases receive the comprehensive care they deserve. The City University of New York, which supported this research, continues to contribute valuable insights into public health challenges and potential solutions.
