Dental Hygienist Requirements in Louisiana: Scope of Practice & Direct Access
Dental Hygienists in Louisiana are regulated by the Louisiana State Board of Dentistry. The ADHA's direct-access chart does not list a provision for Louisiana; that absence is the fact on record, not a statement about what dental hygienists may or may not do there.

What a Dental Hygienist Can Do in Louisiana: Permitted Functions & Supervision Levels
Louisiana's ADHA chart lists most dental hygiene functions at direct supervision, meaning a dentist must be present while the hygienist performs them.
Local anesthesia, scaling and root planing, administering nitrous oxide, study cast impressions, placing and removing periodontal dressings, and removing sutures are each listed at direct supervision.
Oral prophylaxis, x-rays, topical anesthesia, fluoride, and pit/fissure sealants carry two levels apiece, direct and general supervision, depending on setting, per the chart's private/public split.
No function is listed at direct access for Louisiana.
Ten functions, including dental hygiene diagnosis, dental hygiene assessment, treatment planning, prescriptive authority, soft tissue curettage, placing sutures, Botox, lasers, vaccines, and dermal fillers, are not listed on the chart.
- No function is listed at direct access (A) for Louisiana; the highest level recorded on the chart for any function here is general supervision, and that applies to only five functions, split by setting.
- Local anesthesia is listed at direct supervision (D) for Louisiana, meaning the dentist must be present while it is administered.
- Oral prophylaxis, x-rays, topical anesthesia, fluoride, and pit/fissure sealants each carry two levels on Louisiana's chart, direct and general supervision, depending on setting, per the chart's private/public split (D/G).
- Ten of the 22 functions, including dental hygiene diagnosis, treatment planning, and prescriptive authority, are not listed on the chart for Louisiana.
- D
- Direct supervision: dentist needs to be present
- G
- General supervision: dentist needs to authorize prior to services, but need not be present

Local Anesthesia by Dental Hygienists in Louisiana
Louisiana authorized hygienists to administer local anesthesia in 1998, under rules the ADHA chart cites as the authorizing source.
The chart lists direct supervision, both block and infiltration injections, education from an accredited program, and a board-approved exam requirement.
The course requirement it records is 72 hours plus a minimum of 20 injections.
Confirm the current course, exam, and permit requirements with the Louisiana State Board of Dentistry before enrolling or applying.

Silver Diamine Fluoride by Dental Hygienists in Louisiana
ADHA's silver diamine fluoride document does not name SDF for Louisiana.
It cites §701(B), a general delegation provision stating that a dental hygienist may be delegated by a dentist any chairside dental act the dentist deems reasonable, using sound professional judgment — not a fluoride- or topical-agent-specific line, but the broad delegation clause ADHA places SDF under for this state.
ADHA lists supervision as Direct, meaning the dentist must be physically present while the hygienist performs the delegated act.
The quoted provision states no separate training, course, permit, or collaborative-agreement condition beyond the dentist's own determination and presence.
The entry lists no additional references.
A dental hygienist may be delegated by a dentist any chairside dental act which the dentist deems reasonable, using sound professional judgment.

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 Louisiana State Board of Dentistry.
Frequently Asked Questions
Does a dentist have to supervise a dental hygienist in Louisiana?
The ADHA's direct-access chart does not record a provision for Louisiana.
That absence is the fact on record — it is not a statement that dental hygienists cannot practice there.
Confirm supervision requirements with the Louisiana State Board of Dentistry.
Who regulates dental hygienists in Louisiana?
Dental Hygienists in Louisiana are regulated by the Louisiana State Board of Dentistry.
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 in the room for local anesthesia in Louisiana?
Yes.
The ADHA Practice Act chart lists local anesthesia at direct supervision for Louisiana, and the separate Local Anesthesia chart agrees, listing direct supervision since 1998 for both block and infiltration injections.
That means the dentist must be present while the hygienist administers it, not merely available or notified in advance.
Confirm the current supervision and course rules with the Louisiana State Board of Dentistry before relying on this for practice.
Which functions can a Louisiana hygienist perform under general supervision instead of direct supervision?
Five functions on Louisiana's chart carry two levels depending on setting: oral prophylaxis, x-rays, topical anesthesia, fluoride, and pit/fissure sealants are each listed D/G, meaning direct supervision applies in one setting and general supervision in the other, per the chart's private/public split.
Every other listed function for Louisiana sits at direct supervision alone, meaning the dentist must be present.
Confirm which setting applies to a specific placement with the Louisiana State Board of Dentistry.
Does the Louisiana chart list dental hygiene diagnosis or prescriptive authority?
No. Dental hygiene diagnosis, dental hygiene assessment, treatment planning, and prescriptive authority are not listed on the ADHA chart for Louisiana.
The same is true for soft tissue curettage, placing sutures, Botox, lasers, vaccines, and dermal fillers, ten functions in total that carry no supervision level for the state.
Not listed means the chart records no permitted level, a narrower statement than a ban.
Ask the Louisiana State Board of Dentistry what the state's rules say about any of these functions.
Does the chart require a dentist to be present for nitrous oxide in Louisiana?
Yes.
The ADHA chart lists administering nitrous oxide at direct supervision for Louisiana, along with scaling and root planing, study cast impressions, placing and removing periodontal dressings, and removing sutures.
Direct supervision means the dentist must be present while the hygienist performs the function.
The chart does not indicate which cells carry ADHA's numbered footnotes, so confirm any additional conditions with the Louisiana State Board of Dentistry.
Does Louisiana's dental hygiene law name silver diamine fluoride specifically?
No. ADHA's document cites §701(B), a delegation provision letting a dentist delegate to a dental hygienist any chairside dental act the dentist deems reasonable, using sound professional judgment.
It does not name SDF or even fluoride specifically.
ADHA lists supervision as Direct, meaning the dentist must be physically present while the hygienist performs the delegated act.
The provision states no separate training, course, or permit requirement beyond the dentist's own judgment and presence.
Confirm current SDF policy with the Louisiana State Board of Dentistry.
