Average Dental Hygienist Salary in WashingtonNo State Income Tax

Dental hygienists are licensed oral health professionals who provide preventive dental care and educate patients on oral hygiene practices. They work alongside dentists to clean teeth, examine patients for signs of oral disease, and take X-rays. With a BLS median salary of $78,090 and strong job growth of 9% projected through 2032, dental hygiene consistently ranks among the best two-year degree careers. Demand is driven by an aging population requiring ongoing preventive care and the expanding body of research linking oral health to overall health outcomes including heart disease and diabetes.

In Washington, dental hygienists earn an average of $111,817 per year as of 2026, with salaries ranging from $74,318 for entry-level roles to $160,766 for the most experienced professionals — +22.9% above the national average. Pay is influenced most by state licensure level — states permitting local anesthesia and expanded functions typically pay more, specialty practice setting — periodontics, oral surgery, and pediatric dentistry offices pay premiums, and the specific metro area within Washington.
