We are accepting applications to add to our PNWDHI Waitlist for our Local Anesthesia, Nitrous Oxide Psychosedation, and Restorative courses for the Dental Hygienists. We are currently unable to offer the courses in 2022 due to our move to our new dental facility in the Glacier building on the Fort Steilacoom campus. However should this change, we encourage you to submit an application now to be placed on the PNWDHI Waitlist. It is first come, first serve.

Please contact the Washington (WA) State Department of Health for a list of currently approved local anesthesia, nitrous oxide, and restorative courses for WA State dental hygiene licensure. You can access the list here:
