Dental Hygienists. Dental hygienists remove deposits and stains from the surfaces of teeth; apply topical, preventive, or prophylactic agents; polish and smooth restorations; and perform root planing, soft tissue curettage, and other operations and services delegated to them by a licensed dentist. Dental hygienists licensed in Washington may perform dental operations and services only under the supervision of a licensed dentist.
Licensure. A dental hygienist must be licensed to practice in Washington State. The Department of Health (DOH) licenses and regulates dental hygienists. To receive a dental hygienist license, an applicant must successfully complete an approved educational program and pass an examination administered or approved by the Dental Hygiene Examining Committee.
DOH may issue an initial limited license without examination to any applicant who:
A dental hygienist granted a limited license may perform limited procedures, and may obtain endorsements for local anesthesia, restorative procedures, or nitrous oxide analgesia.
The term of a limited license is 18 months and is renewable upon successfully completing an educational program on the administration of local anesthesia and nitrous oxide analgesia, demonstrating relevant didactic and clinical competency, and successfully passing required examinations.
The requirement that an applicant for a limited dental hygienist license be actively practicing in another state or Canadian province is removed.
