COVID-19 pandemic and the widening oral health inequality in Nigeria.

The inequality in access to oral health care in Nigeria is driven by the low numbers of trained health care workers, disproportionate distribution of oral health facilities, low level of oral health awareness, and the challenge associated with out-of-pocket expenditures. The COVID-19 pandemic disrupted oral health care delivery, access to oral health care services, thereby further entrenched inequality by increasing the out-of-pocket expenditure for health due to COVID-19 associated increased cost of medical services; high risk of worsening oral health care needs by patients who have routine and special oral health care needs; increased risk for oral health care needs by persons worse affected by COVID-19; and the high risk for general health problems by those whose access to routine and special health care needs were disrupted by the pandemic. The pandemic has however, also created opportunities to reduce the inequalities in the oral health care sector through adoption of teledentistry; integrated oral and general health care; improving oral health insurance coverage for the informal sector; and increasing public financing for health.
