Dentists are licensed and disciplined by the Dental Quality Assurance Commission (DQAC). In order to be licensed, a dentist must:

A licensed dentist may perform a variety of services, including diagnosing, treating, removing stains or concentrations from the teeth; operating or prescribing for any oral disease, pain, injury, deficiency, deformity, or physical condition; and furnishing, supplying, constructing, reproducing, or repairing any prosthetic denture, bridge, appliance, or other structure to be worn in the human mouth.

A dental laboratory is a facility that manufactures dental care products. Products typically produced by dental laboratories include bridges, crowns, and dentures.


All dental laboratories operating, doing business, or intending to operate or do business in Washington must register with the Department of Health (DOH). A dental laboratory is considered to be doing business in Washington if its work products are prepared pursuant to a work order or work authorization originating in Washington. A dental laboratory is not required to register if it operates under the supervision of a dentist licensed in Washington, as part of a dental practice, or in an educational institution as long as the laboratory does not perform work originating outside of the dentist's office, dental practice, or institution.

"Dental laboratory" is defined as a facility that engages in making, repairing, altering, or supplying artificial restorations, substitutions, appliances, or materials for the correction of disease, loss, deformity, malposition, dislocation, fracture, or injury to the jaws, teeth, lips, gums, cheeks, palate, or associated tissues or parts.

To be registered, a dental laboratory must pay an annual registration fee and submit an application to the DOH that includes:

The DOH must assign each registered dental laboratory a registration number, which must appear on all of the laboratory's invoices. The dentist must include the registration number on all work orders.

Beginning January 31, 2021, the applicant for registration must maintain an employee who works at least 30 hours per week who is either certified in good standing as a dental technician by the National Board for Certification in Dental Laboratory Technology or has successfully completed at least 12 hours of continuing education in dental laboratory technology approved by the National Board for Certification in Dental Laboratory Technology during the 12 months prior to the application.

Beginning January 31, 2025, a laboratory that has not been owned and operated by the same individual since January 1, 1996, must maintain a certified dental technician in good standing with the National Board for Certification in Dental Laboratory Technology who works at least 30 hours per week or demonstrate that it is operated under the supervision of a licensed dentist.

Dental laboratories must renew their registrations every year before July 31.

The DOH may maintain an action, in the manner provided by law, against a dental laboratory that violates the registration requirements for an injunction or other process to restrain or prevent the operation of the establishment without a registration. The Attorney General must advise the DOH and represent the agency in the proceedings.

The registration requirements do not apply to the authorized activities of licensed denturists.
