What a Dental Hygienist Can Do in North Dakota: Permitted Functions & Supervision Levels
North Dakota lists most dental hygiene functions at general supervision on the ADHA Practice Act chart: the dentist authorizes the service in advance but does not need to be present.
Oral prophylaxis, x-rays, topical anesthesia, fluoride, pit/fissure sealants, scaling and root planing, soft tissue curettage, study cast impressions, placing and removing periodontal dressings, and removing sutures all sit at this level.
Local anesthesia and administering nitrous oxide are the two functions listed at indirect supervision, a stricter category requiring the dentist to authorize the procedure and be in the dental office while it is performed.
Dental hygiene diagnosis, treatment planning, dental hygiene assessment, prescriptive authority, placing sutures, Botox, lasers, vaccines and dermal fillers are not listed on the chart for North Dakota.
- Eleven of the 22 functions, including oral prophylaxis, x-rays, and scaling and root planing, are listed at general supervision (G) for North Dakota, where a dentist authorizes in advance but need not be present.
- Local anesthesia and administering nitrous oxide are the two functions listed at indirect supervision (ID), a stricter level requiring the dentist to authorize the procedure and be in the dental office while it is performed.
- No function in North Dakota's row carries a direct-access (A) supervision level — every listed function sits at general or indirect supervision.
- Dental hygiene diagnosis, treatment planning, dental hygiene assessment, prescriptive authority, placing sutures, Botox, lasers, vaccines and dermal fillers carry no supervision level for North Dakota on the chart, which ADHA records as not listed, a narrower statement than a ban.
- G
- General supervision: dentist needs to authorize prior to services, but need not be present
- ID
- Indirect supervision: dentist must authorize procedure and be in the dental office while the procedure is performed

Silver Diamine Fluoride by Dental Hygienists in North Dakota
ADHA's silver diamine fluoride document lists General supervision for North Dakota and cites board rule 20-04-01-01.

ADHA notes that a separate Board Guidance reference clarifies this provision includes SDF.
The provision states no additional condition: no course, training, setting, permit, collaborative agreement, or dentist diagnosis is mentioned in the quoted text.
Dental hygienists may apply topical applications of drugs to the surface tissues of the mouth and to exposed surfaces of the teeth, including anticariogenic agents and desensitizing solutions. Board guidance clarifies this includes SDF.

What Direct Access Does — and Doesn’t — Cover
Direct access is one dimension of scope, not scope itself. The ADHA’s direct-access chart records whether a dental hygienist can initiate treatment and treat a patient without a dentist present — the function-by-function supervision levels and the local anesthesia rules above come from two separate ADHA charts, and the three do not always line up neatly.
Don’t generalize from a direct-access provision to any other part of scope, and confirm specifics with the North Dakota Board of Dental Examiners.
