Improving access to patient care by increasing preventive dental care.

HB 1680 creates a new "oral preventive assistant" license in Washington, allowing trained professionals to perform specific preventive dental services under a dentist's supervision. It directly affects dental practices and patients seeking routine care by expanding who can provide services like cleanings (prophylaxis) and basic gum checks (periodontal probing) for patients with healthy mouths. The bill establishes training requirements, defines the scope of allowable tasks (such as dental assisting duties and non-invasive procedures), and mandates that dentists verify assistants' competency before assigning tasks. This aims to increase access to preventive dental care by adding a new tier of dental support staff, while maintaining dentist oversight for complex procedures.
