BLS metro-level wage data places Dental Assistants pay in Lewiston, ID-WA at a median of $47,360 per year ($22.77/hr/hour), drawn from the OEWS May 2025 release for this Metropolitan Statistical Area. Compared to the national median of $48,070, Lewiston pays 1% below, which typically tracks with a lower local cost of living or smaller specialized-employer cluster. Approximately 100 dental assistantss are employed across the Lewiston MSA in SOC 31-9091.

The Lewiston pay distribution spans from $37,590 at the 10th percentile to $61,110 at the 90th — a 1.6× spread that reflects experience tenure, specialization, employer size, and the difference between public-sector, nonprofit, and private-sector compensation inside the metro. The 25th percentile sits at $45,550 and the 75th at $60,640, so half of Lewiston-based dental assistantss earn within that middle band.

Metro figures capture where you actually work, not just where you live — which matters for commuters. BLS draws metro boundaries from the OMB MSA definitions, so Lewiston, ID-WA covers the central city plus outlying counties tied to the metro economically. Remember that OEWS wages reflect base pay only: employer-provided health insurance, retirement matches, stock options, signing bonuses, overtime, and tips are excluded and can add 20-40% to real total compensation. Before using this metro median as a negotiation anchor, triangulate against the same occupation's national profile (linked below), its state-wide ID data, and peer-metro comparisons — a median is a starting point, not a ceiling.
