In Defense of Dental Therapy: An Evidence-Based Workforce Approach to Improving Access to Care

This article addresses new systems and practice models in community-based dentistry. Its purpose is twofold: to identify strategies and policies that support health equity and access to care; and to identify promising efforts that serve as new models for change in the dental workforce. Dental therapy meets both of these purposes and is the major focus of this article. The fundamental premises explored are threefold. First, the dental care system in the U.S. is broken for many people who then suffer the consequences of poor oral health; this is especially true for racial and ethnic minorities and lower income populations. Second, dental therapy is a proven, safe, high-quality, cost-effective, and ethical way to improve access to oral health care and oral health in general. Third, opposition to dental therapy comes only from the leadership of organized dentistry and is without an evidence base to support objections and criticism. This article reviews each of these three premises in detail. Based on this review, the article concludes that dental therapy is a safe, high-quality, effective, and ethical approach to improve the oral health workforce, increase access to dental care, and achieve oral health equity.
