Dental Hygienist Requirements in Maine: Scope of Practice & Direct Access
Dental Hygienists in Maine are regulated by the Maine Board of Dental Practice. The ADHA records 2 direct-access provisions for Maine — Public Health Dental Hygienist (Rule 02 313 Chap. 2. Sec. 3); Independent Practice Dental Hygienist (32 §18345 & 18375) — the rules that decide whether a dental hygienist there can work without a dentist on site; see below for what they cover.

Maine’s Direct-Access Provisions (2)
Public Health Dental Hygienist
Dental hygienist may provide services in a public or private school, hospital or other nontraditional practice setting under a public health supervision status granted by the dental board on a case-by-case basis.
The dental hygienist may perform services rendered under general supervision.
The dentist should have specific standing orders and procedures to be carried out, although the dentist need not be present when the services have been provided.
A written plan for referral or an agreement for follow-up shall be provided by the public health hygienist recording all conditions that should be called to the attention of the dentist.
The supervising dentist shall review a summary report at the completion of the program or once a year.
Provider services: All services that can be provided under general supervision. Dentist's diagnosis for sealants is not needed in public health or school sealant programs.
Requirements: A dental hygienist must apply to the board to practice providing such information the board deems necessary. The board must take into consideration whether the program will fulfill an unmet need, whether a supervising dentist is available and that the appropriate public health guidelines and standards of care can be met and followed.
Independent Practice Dental Hygienist
Independent practice dental hygienist means an individual licensed to practice independent dental hygiene without supervision of a dentist.
However, a written practice agreement is required when engaging in the taking of dental radiographs pursuant to Chapter 16 of the Board's rules.
Provider services: An independent practice dental hygienist may perform only the following duties without supervision by a dentist: • Interview patients and record complete medical and dental histories; • Take and record the vital signs of blood pressure, pulse and temperature; • Perform oral inspections, recording all conditions that should be called to the attention of a dentist; • Perform complete periodontal and dental restorative charting; • Perform all procedures necessary for a complete prophylaxis, including root planing; • Apply fluoride to control caries; • Apply desensitizing agents to teeth; • Apply topical anesthetics; • Apply sealants; • Smooth and polish amalgam restorations, limited to slow-speed application only; • Take impressions for athletic mouth guards and custom fluoride trays; • Place and remove rubber dams; • Place temporary restorations in compliance with the protocol adopted by the board; • Apply topical antimicrobials, including fluoride but excluding antibiotics, for the purposes of bacterial reduction, caries control and desensitization in the oral cavity. The independent practice dental hygienist shall follow current manufacturer's instructions in the use of these medicaments; • Expose and process radiographs, including but not limited to vertical and horizontal bitewing films, periapical films, panoramic images and full-mouth series, under protocols developed by the board as long as the independent practice dental hygienist has a written agreement with a licensed dentist that provides that the dentist is available to interpret all dental radiographs within 21 days from the date the radiograph is taken and that the dentist will sign a radiographic review and findings form; and • Prescribe, dispense or administer anticavity toothpastes or topical gels with 1.1% or less sodium fluoride and oral rinses with 0.05%, 0.2%, 0.44% or 0.5% sodium fluoride, as well as chlorhexidine gluconate oral rinse. For the purposes of this paragraph, "topical" includes superficial and intraoral application.
Requirements: Verification of 2,000 work hours of clinical practice. For purposes of meeting the clinical practice requirements, the applicant's hours in a private dental practice or nonprofit setting under the supervision of a dentist may be included as well as the applicant's hours as a public health dental hygienist or, prior to July 29, 2016, as a dental hygienist with public health supervision status.
What a Dental Hygienist Can Do in Maine: Permitted Functions & Supervision Levels
Maine lists most day-to-day hygiene functions at direct access on the ADHA chart: oral prophylaxis, x-rays, topical anesthesia, fluoride, sealants, scaling and root planing, soft tissue curettage, study cast impressions, placing and removing periodontal dressings, removing sutures, dental hygiene diagnosis, treatment planning, and dental hygiene assessment are all listed at direct access, meaning the hygienist provides them as they determine appropriate without specific authorization.
Two functions carry direct supervision, meaning the dentist must be present: administering nitrous oxide and prescriptive authority.
Local anesthesia sits at general supervision, where a dentist authorizes in advance but need not be present.
Placing sutures, Botox, lasers, vaccines and dermal fillers are not listed on the chart for Maine.
- Fourteen of the 22 functions, including dental hygiene diagnosis, treatment planning and dental hygiene assessment, are listed at direct access (A) for Maine.
- Prescriptive authority is listed at direct supervision (D) for Maine, meaning the dentist must be present — a stricter level than the direct access most other listed functions carry.
- Local anesthesia is listed at general supervision (G), not direct access, so a dentist must authorize it in advance even though most other listed services need no authorization.
- Administering nitrous oxide also carries direct supervision (D), the same level as prescriptive authority.
- Placing sutures, Botox, lasers, vaccines and dermal fillers carry no supervision level for Maine on the chart, which ADHA records as not listed, a narrower statement than a ban.
- A
- Direct access: hygienists can provide services as s/he determines appropriate without specific authorization
- G
- General supervision: dentist needs to authorize prior to services, but need not be present
- D
- Direct supervision: dentist needs to be present

Local Anesthesia by Dental Hygienists in Maine
Maine authorized hygienists to administer local anesthesia in 1997.
The ADHA chart lists direct supervision, meaning the dentist must be present, for both block and infiltration injections, with education from an accredited program and a board-administered exam.
It records the authorization as by rule rather than statute, with a course requirement of 40 hours plus a minimum of 50 injections.
Confirm the current course and permit rules with the Maine Board of Dental Practice before enrolling or applying.

Silver Diamine Fluoride by Dental Hygienists in Maine
ADHA's silver diamine fluoride document does not name SDF for Maine; it quotes the state's general fluoride and topical-agent provisions under §02-313 instead, and SDF falls under that language.
ADHA lists supervision as General or Public Health Supervision.
Under the general scope of practice, a hygienist may apply fluoride to control caries and apply desensitizing agents.
Under Public Health Supervision, a hygienist may additionally apply topical antimicrobials, excluding antibiotics, including fluoride, for bacterial reduction, caries control and desensitization in the oral cavity, and must follow current manufacturer's instructions in using these medicaments.
Scope of practice allows dental hygienist to apply fluoride to control caries and apply desensitizing agents.
Under Public Health Supervision, a dental hygienist may also apply fluoride. Additionally, under Public Health Supervision, a dental hygienist may apply topical antimicrobials (excluding antibiotics), including fluoride for the purposes of bacterial reduction, caries control and desensitization in the oral cavity. The practitioner must follow current manufacturer’s instructions in the use of these medicaments.

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 Maine Board of Dental Practice.
Frequently Asked Questions
Does a dentist have to supervise a dental hygienist in Maine?
It depends on which provision applies.
Under the 2001 Public Health Dental Hygienist provision (Rule 02 313 Chap. 2.
Sec. 3), general supervision still applies — the dentist need not be present, but care runs under the dentist's standing orders, and the arrangement must be granted by the board case-by-case with a supervising dentist available.
Under the 2008/2015/2017 Independent Practice Dental Hygienist license (32 §18345 & 18375), a hygienist may practice without a dentist's supervision for the license's listed duties, but only after obtaining that separate license (verification of 2,000 clinical hours), and a written practice agreement with a dentist is still required specifically for taking dental radiographs.
Neither is an unconditional "no supervision needed." Confirm current details with the Maine Board of Dental Practice.
Who regulates dental hygienists in Maine?
Dental Hygienists in Maine are regulated by the Maine Board of Dental Practice.
Scope of practice is set by state law and changes over time, so verify current rules directly with the board before relying on them.
Can a dental hygienist in Maine give local anesthesia without a dentist present?
No. The ADHA Practice Act chart lists local anesthesia in Maine at direct supervision, and the Local Anesthesia chart confirms direct supervision for both block and infiltration injections since 1997, meaning a dentist must be present while it is administered.
That is a stricter level than the direct access most other Maine hygiene functions carry.
The chart also lists a board-administered exam and a 40-hour course with a minimum of 50 injections.
Confirm current requirements with the Maine Board of Dental Practice.
Does the ADHA chart give Maine hygienists prescriptive authority?
The chart lists prescriptive authority for Maine at direct supervision, meaning the dentist must be present, rather than at direct access like most of the state's other listed functions.
The chart does not say which prescriptions this covers or under what circumstances — ADHA's numbered footnote markers did not survive extraction, so any qualifier attached to this cell is not stated here.
Check with the Maine Board of Dental Practice for what this authority covers in practice and how it is exercised.
Which hygiene functions in Maine require the dentist to be present?
Two functions on the ADHA Practice Act chart carry direct supervision for Maine: administering nitrous oxide and prescriptive authority.
Direct supervision means the dentist must be present while the function is performed.
Local anesthesia sits one level lower, at general supervision, where the dentist authorizes in advance but does not need to be present.
The chart does not indicate which cells carry ADHA's numbered footnotes, so confirm any additional conditions with the Maine Board of Dental Practice.
Does the Maine chart list hygienists administering Botox or vaccines?
No. Botox, vaccines, lasers, dermal fillers and placing sutures are not listed on the ADHA Practice Act chart for Maine.
ADHA records a dash as not listed on the chart, which is a narrower statement than a prohibition — it does not confirm the function is disallowed, only that the chart does not list a supervision level for it in Maine.
For a definitive answer on whether these fall within Maine hygiene scope, contact the Maine Board of Dental Practice.
Does ADHA's SDF document name silver diamine fluoride for Maine hygienists?
No. ADHA's entry for Maine never uses the term silver diamine fluoride; it quotes §02-313, which lets a hygienist apply fluoride to control caries and apply desensitizing agents, plus a Public Health Supervision provision adding topical antimicrobials, including fluoride, for bacterial reduction, caries control and desensitization, with the practitioner following current manufacturer's instructions.
ADHA places SDF under that fluoride and topical-antimicrobial language rather than a provision that names it.
Confirm with the Maine Board of Dental Practice whether an SDF product falls under this authority.
What supervision applies to a Maine hygienist applying fluoride or SDF products?
ADHA lists General or Public Health Supervision for Maine.
The general fluoride and desensitizing-agent provision in §02-313 applies under general supervision as written.
Under Public Health Supervision, a status the board grants case by case, a hygienist may additionally apply topical antimicrobials, including fluoride, for bacterial reduction, caries control and desensitization, following current manufacturer's instructions.
The document lists no separate training or setting condition beyond that.
Confirm current details with the Maine Board of Dental Practice.
