The bill aims to enhance access to preventive dental care in Washington State by addressing barriers created by federal actions and private sector coverage restrictions. It emphasizes the importance of preventive dental services in maintaining oral and overall health, particularly in preventing the progression of oral diseases linked to systemic health conditions. The legislature expresses concern over recent federal proposals to limit fluoride use and the imposition of age and frequency restrictions by dental benefit carriers, which disproportionately affect vulnerable populations.

To improve access, the bill mandates that health carriers cover preventive dental services without age or frequency limitations, allowing the treating dentist and the patient to determine the medically necessary services. It also stipulates that health carriers must reimburse providers for both preventive services and any required adjunctive services. The bill defines "preventive dental services" to include a range of treatments such as fluoride application, sealants, and oral cancer screenings, thereby promoting equity in dental care and supporting the overall health of Washington residents.
