Oral Health and Community Program Planning


Oral health is a key indicator of overall health, well-being and quality of life.  In order to determine how to improve oral health within a community, it is important to first obtain an evidence-based understanding of the community and its current health and oral health needs and existing resources.

Oral disease affects every community. It is the responsibility of public health agencies to assess the oral health needs of the communities they serve and develop programs and policies to ensure that those needs are met. Implementing health interventions is a crucial step in improving community health outcomes at the local, tribal, territorial, state, and national level.  Addressing health in communities involves planning, by ensuring that the built environment—where people live, work, and play, also promotes health lifestyles.  

By following the Health Promotion/Disease Prevention POARE model, public health agencies and dental team members will be able to clearly identify a problem of importance to the community they serve, make plans for the best use of resources, and plan a thorough evaluation of the program.
