This document discusses strategies for preventing periodontal disease as a public health problem in the UK. It argues that current approaches focus too much on downstream treatment rather than upstream prevention. It advocates for whole population prevention strategies like reducing risk factors through public health measures, health education and policy changes. These include integrating oral hygiene education into schools, using media campaigns, and making oral hygiene products more affordable. A combination of population-level interventions and some targeted high-risk approaches is recommended over just clinical treatment to more effectively address periodontal disease on a public health scale.
