Dental Hygiene License

Washington State holds 6,089 active credentials of this type — 1.1% of every active health care credential in the state. Here is what that number is made of, and how to check one.

What kind of credential this is

A Dental Hygiene License is a License — the broadest of Washington’s credentials. Where the state licenses a profession, it is generally unlawful to practise it without holding one, and the holder answers to the Department for how they practise.

That word is not a formality. Washington issues 304,441 active credentials in this form across the state, and it decides what the holder may do without someone else’s supervision. How a license differs from the others.

When these credentials expire

Washington renews on the holder’s birthday, so these 6,089 expiry dates are spread right across the calendar rather than falling together. By year:

Continuing education

The Department records a continuing-education due date for 6,080 of these 6,089 credentials (99.9%). Where it is absent, that does not mean no hours are owed — it means this file does not carry the date.

How long these holders have been credentialled

The oldest Dental Hygiene License credential still active in Washington was first issued in 1964. 662 of the 6,089 were issued in 2024 or later — 10.9% of the profession is that new.

The disciplinary flag

2 of the 6,089 active credentials of this type carry a disciplinary flag in the Department’s file — 0.0% — and 8 carry one marked pending.

This site publishes that count and no more: never who. The reason is not discretion, it is accuracy — the published file carries a yes/no flag and nothing else: no reason, no date, no case number. Naming someone on the strength of it would publish a suspicion rather than a fact. Every credential counted here is active. Why the line is drawn there.

Do not let the date pass

6,089 credentials of this type are active in Washington. Washington renews most of them on the holder’s birthday, every year or every two years, and continuing-education hours have to be done before that date — not after. Leave your details and we will tell you when yours is close, and pass your request for continuing-education hours to providers who teach for this credential.

We take no commission and we vouch for no training provider. We have no arrangement with any provider today — we are collecting these requests in order to go and find them. What we do with this.
