Dental Assistant Salary in Washington 2026,
$58,090 Median | BLS Data by City

The published figure is $58,090 a year, or $27.93 an hour, per BLS OEWS May 2025 for SOC 31-9091, with a band from $46,280 at the 10th percentile to $68,230 at the 90th. That is 20.8% above the national median of $48,070, and Washington's 25th percentile of $48,780 already exceeds the national midpoint for the occupation.

Seattle-Tacoma-Bellevue, at $62,040, and by a wide margin — Spokane-Spokane Valley follows at $50,980, then Bellingham $49,830, Bremerton-Silverdale-Port Orchard $49,800 and Walla Walla $49,790. Puget Sound is the outlier market for this occupation in Washington, and the other four metros sit within about $1,200 of each other.

Yes. The Washington State Department of Health registers dental assistants, and it separately licenses the Expanded Function Dental Auxiliary, which authorises restorative procedures beyond the registered scope. There is also a distinct dental anesthesia assistant credential. Which credential an assistant holds determines what a practice may legally delegate to them.

A licensed tier above ordinary dental assistant registration, requiring additional approved training and examination through the Department of Health. An EFDA may perform restorative procedures that in many states only a dentist or hygienist may carry out. It is the state's own pay lever for this occupation and largely explains the $62,340 seventy-fifth percentile and $68,230 ninetieth percentile.

A location quotient of 1.47 across 13,050 jobs means the state employs them at nearly fifty per cent above the national rate for its size. Two things drive that: a well-insured population with high dental utilisation, particularly in the Puget Sound corridor, and a credential structure that permits practices to delegate more clinical work to assistants than many states allow, which makes each dentist's chair support more assistant hours.

Because dental demand is income-elastic and Puget Sound has the income. Seattle-Tacoma-Bellevue at $62,040 sits above Spokane-Spokane Valley $50,980, Bellingham $49,830, Bremerton-Silverdale-Port Orchard $49,800 and Walla Walla $49,790 — the other four clustered within about $1,200. Elective and cosmetic dentistry, employer dental coverage through the region's technology sector, and a practice market that has consolidated into well-capitalised groups all concentrate in one metro. The rest of Washington runs on a general-practice mix where the statewide wage floor does more of the work than local demand does.

The $58,090 median blends a $62,040 Seattle market with four metros around $50,000, so it describes neither well. Anyone benchmarking a Puget Sound offer should use the Seattle metro figure; anyone in Spokane or the eastern half of the state should read from the $48,780 twenty-fifth percentile upward. The figure is also straight-time, and Washington dental practices commonly pay production or hygiene-coverage bonuses that sit outside it, particularly in the corporate group practices that dominate the Seattle market.

The EFDA licence, more than anything else. It is the only credential in this occupation that changes what a practice may legally bill for an assistant's time, and it accounts for much of the gap between the $58,090 median and the $62,340 seventy-fifth percentile. Beyond it, specialty practice — oral surgery, orthodontics and the dental anesthesia assistant credential — pays above general dentistry, and lead clinical or office-management roles in multi-chair Puget Sound practices are what the $68,230 ninetieth percentile mostly represents.
