Dental Hygienist Requirements in Kentucky: Scope of Practice & Direct Access
Dental Hygienists in Kentucky are regulated by the Kentucky Board of Dentistry. The ADHA records 2 direct-access provisions for Kentucky — Volunteer Community Health Settings (Sec. 313.040); Public Health Dental Hygienist (201 KAR 8:562) — the rules that decide whether a dental hygienist there can work without a dentist on site; see below for what they cover.

Volunteer Community Health Settings
A dental hygienist may provide the services listed below without the supervision of a dentist in volunteer community health settings.
Provider services: Dental hygienist can provide dental hygiene instruction, nutritional counseling, oral screening with subsequent referral to a dentist, fluoride application, demonstration of oral hygiene technique, and sealants.
Public Health Dental Hygienist
A public health dental hygienist shall perform dental hygiene services under the supervision of the governing board of health.

Provider services: Limited to preventative services.
Requirements: Dental hygienist must have 2 years and 3,000 hours of experience. During each renewal period, complete a 3 hour course approved by the board on the identification and prevention of potential medical emergencies, as well as 5 hours of other CE in area of public health or public dental health. A dental hygienist authorized to practice as a public health dental hygienist shall receive a certificate from the board indicating their registration.

What a Dental Hygienist Can Do in Kentucky: Permitted Functions & Supervision Levels
Kentucky's row on the ADHA Practice Act chart centers on general supervision, where a dentist authorizes a service in advance but does not need to be present.
Eleven functions carry that level, including oral prophylaxis, x-rays, topical anesthesia, fluoride, pit/fissure sealants, scaling and root planing, study cast impressions, placing and removing periodontal dressings, removing sutures, and prescriptive authority.
Four functions require direct supervision, with the dentist present: local anesthesia, soft tissue curettage, administering nitrous oxide, and using lasers.
Seven functions are not listed on Kentucky's row, including placing sutures, dental hygiene diagnosis, treatment planning, dental hygiene assessment, Botox, vaccines, and dermal fillers.
No function on the chart is listed at direct access for Kentucky.
- Local anesthesia is listed at direct supervision (D) for Kentucky, meaning the dentist must be present, matching the direct-supervision listing on the separate Local Anesthesia chart.
- Soft tissue curettage, administering nitrous oxide, and using lasers are also listed at direct supervision, the strictest level that appears on Kentucky's row.
- No function on Kentucky's row is listed at direct access; general supervision, where the dentist authorizes in advance but need not be present, is the least restrictive level shown, covering eleven functions including prescriptive authority.
- Dental hygiene diagnosis, treatment planning, and dental hygiene assessment carry no supervision level on Kentucky's row — the chart records these as not listed.
- 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 Kentucky
Kentucky's Local Anesthesia chart entry lists 2002 as the year implemented, with supervision at the direct level, matching the direct-supervision listing for local anesthesia on the Practice Act row.
Both block and infiltration injections are listed, with education from an accredited or board-approved program and a written exam given by the course.
The chart credits the authorization to statute and records a course requirement of 32 hours didactic and 12 hours clinical.
Confirm current course and exam requirements with the Kentucky Board of Dentistry before enrolling.

Silver Diamine Fluoride by Dental Hygienists in Kentucky
ADHA's silver diamine fluoride document names SDF directly for Kentucky rather than folding it under fluoride, but the state has no scope-of-practice citation and no supervision level on record.
The only source is board meeting minutes from July 14, 2018: the Kentucky Board of Dentistry formed an SDF Committee to review whether dental hygienists may apply SDF, held its first meeting in September 2018, and the matter is still pending as of that record.
No training, course, setting, or collaborative-agreement condition has been set because no rule has been adopted.
The Board formed a SDF Committee to review the issue of whether dental hygienists may apply SDF. The first SDF committee meeting was held September 2018. The matter is still pending.

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 Kentucky Board of Dentistry.
Frequently Asked Questions
Does a dentist have to supervise a dental hygienist in Kentucky?
It depends on which provision applies.
Under the 2010 Volunteer Community Health Settings provision (Sec. 313.040), a dental hygienist may provide a specific list of services — hygiene instruction, nutritional counseling, oral screening with referral to a dentist, fluoride application, demonstration of oral hygiene technique, and sealants — without a dentist's supervision, but only in volunteer community health settings.
Under the 2010 Public Health Dental Hygienist provision (201 KAR 8:562), a hygienist performs services under the supervision of the governing board of health rather than a dentist directly, but only in specific settings (local health departments, affiliated educational institutions, contracted mobile dental health programs, and certain public/private institutions), only after meeting registration requirements (2 years and 3,000 hours of experience, board-approved continuing education, and informed consent), and limited to preventive services for ASA I/II patients.
Neither is an unconditional "no supervision needed." Confirm current details with the Kentucky Board of Dentistry.
Who regulates dental hygienists in Kentucky?
Dental Hygienists in Kentucky are regulated by the Kentucky 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.
Which dental hygiene functions in Kentucky require the dentist to be present?
Local anesthesia, soft tissue curettage, administering nitrous oxide, and using lasers are listed at direct supervision on the ADHA Practice Act chart for Kentucky, meaning the dentist must be present.
Every other function that is listed on Kentucky's row sits at general supervision, where the dentist authorizes the service in advance but does not need to be present.
Confirm current requirements with the Kentucky Board of Dentistry.
Does the Kentucky chart list dental hygiene diagnosis or prescriptive authority?
Prescriptive authority is listed at general supervision for Kentucky, meaning a dentist authorizes it in advance but need not be present.
Dental hygiene diagnosis, treatment planning, and dental hygiene assessment are not listed on Kentucky's row, so the chart records no supervision level for them rather than granting or denying the function.
Check with the Kentucky Board of Dentistry for how these terms are defined under state law.
Does the ADHA chart cover Botox, vaccines, or dermal fillers for Kentucky hygienists?
No. Placing sutures, Botox, vaccines, and dermal fillers all carry no supervision level on Kentucky's row of the chart.
ADHA records these as not listed, which is a narrower statement than saying the function is off-limits.
Ask the Kentucky Board of Dentistry directly about any of these functions before relying on the chart alone.
Is local anesthesia held to a stricter supervision level than other functions in Kentucky?
Yes.
Local anesthesia is listed at direct supervision on Kentucky's Practice Act row, meaning the dentist must be present, while most of the functions that are listed, including oral prophylaxis, x-rays, topical anesthesia, fluoride, and sealants, sit at general supervision.
The separate Local Anesthesia chart independently lists direct supervision for Kentucky as well.
Confirm current requirements with the Kentucky Board of Dentistry.
Can a dental hygienist in Kentucky apply silver diamine fluoride?
Not yet under any adopted rule.
ADHA's SDF document records no scope-of-practice citation and no supervision level for Kentucky at all.
The only record is board meeting minutes from July 14, 2018, showing the Kentucky Board of Dentistry formed an SDF Committee that first met in September 2018 to review whether hygienists may apply SDF, with the matter still pending.
Contact the Kentucky Board of Dentistry for the committee's current status.
Does Kentucky's Practice Act chart say anything about silver diamine fluoride?
That is a separate document and does not name SDF.
The Practice Act chart lists Kentucky's Fluoride function at general supervision, while ADHA's SDF document records no scope-of-practice citation or supervision level for Kentucky at all, only board minutes describing a still-pending SDF Committee formed in 2018.
The two sources answer different questions, so do not treat the fluoride listing as an answer about SDF.
Ask the Kentucky Board of Dentistry directly.
