Dental Hygienist Requirements in Nevada: Scope of Practice & Direct Access

It depends on the setting.

Under the 1998 Public Health Dental Hygienist provision (Sec. 631.287), a hygienist can work without a dentist present in an approved public-health setting — a school, community center, hospital, nursing home, or another location the state dental health officer approves — but only after getting a special endorsement from the dental board and submitting a protocol describing how services will be provided.

Local anesthesia and nitrous oxide still require dentist authorization and facility equipment meeting the board's standards.

Outside an approved endorsement and setting, this isn't an unconditional "no supervision needed." Confirm current details with the Nevada State Board of Dental Examiners.

Dental Hygienists in Nevada are regulated by the Nevada State Board of Dental Examiners.

Scope of practice is set by state law and changes over time, so verify current rules directly with the board before relying on them.

The ADHA Local Anesthesia chart lists Nevada's supervision as a mix of direct and general, meaning the requirement depends on which setting or step applies rather than a single level throughout.

Nevada's Practice Act chart also lists local anesthesia at two levels (ID/D), indirect supervision in one setting and direct supervision in the other, both requiring a dentist in the dental office.

Because the exact requirement depends on setting, confirm the current rule with the Nevada State Board of Dental Examiners before administering local anesthesia.

Local anesthesia and administering nitrous oxide both carry direct supervision in one of their two listed settings (ID/D) on Nevada's ADHA Practice Act chart, meaning a dentist must be present for at least part of how they're delivered.

Most other listed functions, including oral prophylaxis and scaling and root planing, sit at general supervision or direct access instead.

The chart doesn't show which cells carry ADHA's numbered footnotes, so check the Nevada State Board of Dental Examiners' rules for any added condition on these two functions.

Prescriptive authority is listed at general supervision (G) for Nevada, meaning a dentist authorizes it in advance but doesn't need to be present.

Dental hygiene diagnosis, treatment planning, and dental hygiene assessment are not listed on the chart for Nevada, which ADHA records as not listed, a narrower statement than a ban.

Anyone considering these functions should confirm current scope with the Nevada State Board of Dental Examiners rather than relying on the chart's silence.

Some functions on the ADHA chart list two letters for Nevada instead of one, such as oral prophylaxis (G/A) and local anesthesia (ID/D).

That means the function sits at one supervision level in a private setting and a different level in a public setting; it is not a range or an average, and each setting carries its own listed level.

Confirm which applies to a given practice setting with the Nevada State Board of Dental Examiners.

Not automatically.

ADHA's entry cites the Nevada Board's July 19, 2019 advisory opinion stating that placing silver diamine and glass ionomer is within a dental hygienist's scope only when the hygienist holds a public health endorsement meeting the requirements of NAC 631.210(6)(b).

Without that endorsement, the entry does not describe SDF placement as within scope.

Confirm current endorsement requirements with the Nevada State Board of Dental Examiners.

ADHA's entry notes that the Nevada Board recommends public-health-endorsed dental hygienists follow the Nevada Policy for the Application of Silver Diamine Fluoride, which includes using informed consent.

The entry states this as the Board's recommendation, not a separately quoted statute.

Ask the Nevada State Board of Dental Examiners for the current policy text and any consent requirement before applying silver diamine fluoride.
