Monitoring Use of Medical Services for Oral Health Care to Assess an Expansion of Public Dental Programs in Canada

OBJECTIVES: Oral health disparities disproportionately affect low-income populations, with cost a significant barrier to accessing dental care. In Canada, individuals with untreated oral conditions often visit publicly funded medical services, which are not designed to provide dental treatment. The recently launched Canadian Dental Care Plan (CDCP) is intended to expand access to dental services for low-income populations. This commentary argues that reduced medical service use for non-traumatic dental conditions (NTDCs) is a potential benefit that should be monitored to evaluate the impact of the CDCP. METHODS: Canadian studies reporting use and cost estimates of physician visits, emergency department use, and hospital-based care for dental conditions were described. Data sources for routine monitoring of use were identified. RESULTS: In Ontario Canada, use and costs of physician and emergency department visits, and hospital-based care for NTDCs were estimated at over $29M annually during 2003-2015 (population approximately 30 million). These estimates were conservative, with other studies suggesting higher visit volumes and costs depending on case definitions. National hospital and provincial physician billing databases are available for routine monitoring but indicators need to be standardized and data quality assessed. Stratified reporting can monitor equity impacts. CONCLUSIONS: Medical oral health care use is a potential indicator of effectiveness of public dental programs. A decline could signal improved access to dental services while persistent rates may highlight gaps in program reach. Monitoring this indicator is relevant to Canada and other jurisdictions seeking to advance oral health equity through expanded public coverage.
