Dental hygienist license requirements by state

Each state licenses its own hygienists. The guides below cover exams, fees, licensure for hygienists already licensed elsewhere, local anesthesia and nitrous oxide rules, supervision, and renewal. Each item cites the state board or code page it came from and the date it was checked.

Rules change. Confirm anything you rely on with the state board before you apply or schedule a hygienist.
