Dental Hygienist Requirements in Wyoming: Scope of Practice & Direct Access
Dental Hygienists in Wyoming are regulated by the Wyoming Board of Dental Examiners. The ADHA records a direct-access provision for Wyoming — 2017 provision (Rules Chapter 7, Section 5(c)) — the rule that decides whether a dental hygienist there can work without a dentist on site; see below for what it covers.

Wyoming’s Direct-Access Provision: 2017 provision
Public Health Dental Hygienist The Wyoming Dental Board adopted regulations allowing the public to directly access limited dental hygiene services from a Public Health Dental Hygienist.
A public health dental hygienist may provide public health services at facilities to include, but not limited to: • federally funded health centers and clinics • nursing homes • extended care facilities • home health agencies • group homes for the elderly, disabled and youth • public health offices • Women, Infants, and Children (WIC) • Head Start programs • child development programs • early intervention programs • migrant work facilities • free clinics • health fairs • public and private schools • state and county correctional institutions • community school-based prevention programs • public health vans
Provider services: Public health services solely consist of prophylaxis, fluoride varnishes, oral health education, and dental screenings. These services can be provided by the hygienist without prior authorization of the dentist. All patients seen shall be referred to a dentist annually.
Requirements: The public health hygienist must submit a Collaboration Agreement with a Wyoming licensed dentist. The hygienist must have a current Wyoming dental hygienist license with a minimum of two years clinical experience. Lastly, the dental hygienist must carry liability insurance.
What a Dental Hygienist Can Do in Wyoming: Permitted Functions & Supervision Levels
Wyoming's ADHA chart leans toward supervision that keeps the dentist present rather than direct access.
Seven functions — x-rays, local anesthesia, topical anesthesia, scaling and root planing, placing and removing periodontal dressings, and removing sutures — sit at direct supervision, where the dentist must be in the office while the hygienist performs them.
Three functions, fluoride, pit/fissure sealants and study cast impressions, sit at general supervision, where the dentist authorizes in advance but need not be present.
Oral prophylaxis carries two levels for Wyoming: general supervision in one setting and indirect supervision, which requires the dentist in the office, in the other, split by private and public settings.
Eleven functions, including dental hygiene diagnosis, treatment planning, dental hygiene assessment and prescriptive authority, are not listed on the chart for Wyoming.
No function is listed at direct access.
- No function on the Wyoming chart is listed at direct access (A); the least-supervised level that appears is general supervision (G).
- Seven functions, including x-rays, local anesthesia and topical anesthesia, are listed at direct supervision (D), meaning the dentist must be in the office while the hygienist performs them.
- Oral prophylaxis is listed at two levels for Wyoming, general supervision (G) and indirect supervision (ID), split by private and public settings per ADHA's multi-letter note.
- Local anesthesia is listed at direct supervision (D) on the Practice Act chart, and the separate Local Anesthesia chart lists direct supervision too, in place since 1991.
- Eleven functions, including dental hygiene diagnosis, treatment planning, prescriptive authority and vaccines, are not listed on Wyoming's chart, which ADHA records as not listed rather than as barred.
- 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
- D
- Direct supervision: dentist needs to be present

Silver Diamine Fluoride by Dental Hygienists in Wyoming
ADHA's silver diamine fluoride document does not name SDF for Wyoming.
Instead it quotes the Wyoming Board's guidance that scope of practice includes applying topical medications, that the Board concurs fluoride applications are topical medications, and that hygienists can therefore apply fluoride under general supervision.
ADHA lists the state's scope-of-practice citation as Chapter 7 and its own supervision line as General.
The quoted guidance attaches no separate training, course, setting or permit condition beyond classifying fluoride as a topical medication under that Chapter.
Scope of practice includes applying topical medications and the Board concurs that fluoride applications are topical medications. The Board concurs that fluoride applications are topical medications. Therefore, dental hygienists can apply fluoride under general supervision.

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 Wyoming Board of Dental Examiners.
Frequently Asked Questions
Does a dentist have to supervise a dental hygienist in Wyoming?
Not fully.
Wyoming's Public Health Dental Hygienist provision (Rules Chapter 7, Section 5(c)) lets a hygienist provide limited services — prophylaxis, fluoride varnishes, oral health education, and dental screenings — without a dentist's prior authorization, but only at qualifying public health settings such as federally funded health centers, nursing homes, schools, and WIC or Head Start programs.
To practice under it, the hygienist must submit a Collaboration Agreement with a Wyoming-licensed dentist, hold a current Wyoming dental hygienist license with at least two years of clinical experience, carry liability insurance, and refer every patient seen to a dentist annually.
Outside those settings and services, this provision doesn't apply.
Confirm current details with the Wyoming Board of Dental Examiners.
Who regulates dental hygienists in Wyoming?
Dental Hygienists in Wyoming are regulated by the Wyoming 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.
Does a dentist have to be present when a Wyoming hygienist gives local anesthesia?
Yes.
Both the ADHA Practice Act chart and the separate Local Anesthesia chart list direct supervision for local anesthesia in Wyoming, meaning a dentist must be present in the office while the hygienist administers it.
Wyoming's Local Anesthesia chart dates this to 1991 and covers both block and infiltration injections, with an exam requirement and board-approved education listed.
Confirm current permit rules with the Wyoming Board of Dental Examiners.
Which hygiene functions in Wyoming don't require the dentist to be in the room?
Three functions on the chart, fluoride, pit/fissure sealants and study cast impressions, sit at general supervision for Wyoming, meaning the dentist authorizes the service in advance but does not need to be present.
Oral prophylaxis is split: general supervision in one setting and indirect supervision, which does require the dentist in the office, in the other.
Every other listed function, including local anesthesia, sits at direct supervision.
Confirm current rules with the Wyoming Board of Dental Examiners.
Does Wyoming's chart list dental hygiene diagnosis or prescriptive authority?
No. The ADHA Practice Act chart lists dental hygiene diagnosis, dental hygiene assessment, treatment planning and prescriptive authority as not listed for Wyoming, along with soft tissue curettage, administering nitrous oxide, placing sutures, Botox, lasers, vaccines and dermal fillers.
Not listed means the function does not appear on this chart, not that state law bars it.
Check with the Wyoming Board of Dental Examiners for the state's current scope of practice on any of these.
Does Wyoming's ADHA entry say hygienists can apply silver diamine fluoride?
Not by name.
The entry ADHA cites for Wyoming is Board guidance holding that fluoride applications are topical medications within a hygienist's scope of practice, and that this work is done under general supervision.
It covers SDF only insofar as SDF is a fluoride application; it does not use the term SDF or attach any separate training or setting requirement in the text ADHA quotes.
Confirm current guidance with the Wyoming Board of Dental Examiners.
