Dental Hygienist Requirements in Texas: Scope of Practice & Direct Access
Dental Hygienists in Texas are regulated by the Texas State Board of Dental Examiners. The ADHA records a direct-access provision for Texas — General Supervision (Sec. 262.1515) — the rule that decides whether a dental hygienist there can work without a dentist on site; see below for what it covers.

What a Dental Hygienist Can Do in Texas: Permitted Functions & Supervision Levels
Texas splits its 22 ADHA-listed hygiene functions into two supervision levels, with none reaching direct access.
Eleven functions — oral prophylaxis, x-rays, topical anesthesia, fluoride, pit/fissure sealants, scaling and root planing, soft tissue curettage, study cast impressions, placing and removing periodontal dressings, and removing sutures — sit at general supervision, where a dentist authorizes the service in advance but does not need to be present.
Local anesthesia and using lasers are the two functions listed at direct supervision, requiring the dentist in the room.
The remaining nine functions — administering nitrous oxide, placing sutures, dental hygiene diagnosis, treatment planning, dental hygiene assessment, prescriptive authority, Botox, vaccines, and dermal fillers — are not listed on the chart for Texas.
- Local anesthesia and using lasers are the only two functions listed at direct supervision (D) for Texas, meaning the dentist must be present while they're performed.
- Eleven functions, including oral prophylaxis, x-rays, and scaling and root planing, sit at general supervision (G) for Texas — a dentist authorizes the service in advance but need not be present.
- Dental hygiene diagnosis, dental hygiene assessment, treatment planning, and prescriptive authority carry no supervision level for Texas on the chart, which ADHA records as not listed, a narrower statement than a ban.
- Administering nitrous oxide, placing sutures, Botox, vaccines and dermal fillers are also not listed on the chart for Texas.
- 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 Texas
Texas authorized hygienists to administer local anesthesia in 2023, under direct supervision, meaning the dentist must be present.
The chart lists infiltration injections only, not block.
Education must come from an accredited, Board-approved, or CODA-approved course, and the chart lists a TSBDE-approved certification exam.
Authorization comes through Board rules.
The course requirement is 20 hours didactic and 12 hours clinical, with the didactic curriculum overseen by a Texas-licensed dentist experienced in teaching local anesthesia.
Confirm current course and exam requirements with the Texas State Board of Dental Examiners.

Silver Diamine Fluoride by Dental Hygienists in Texas
ADHA's silver diamine fluoride document does not name SDF for Texas.
It instead cites §115.2, which lets a dental hygienist topically apply drugs to the surface tissues of the human mouth or the exposed surface of human teeth — the provision ADHA places SDF under as a topically applied drug.
ADHA lists supervision for this provision as Direct or General.
The quoted language does not attach a training requirement, a course, a specific setting, a permit, or a collaborative agreement, and it does not require the dentist to diagnose first.
Confirm current requirements with the Texas State Board of Dental Examiners before applying SDF.

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 Texas State Board of Dental Examiners.
Frequently Asked Questions
Does a dentist have to supervise a dental hygienist in Texas?
Only within limits.
Texas's General Supervision provision (Sec. 262.1515) lets a dental hygienist provide services for up to 6 months without a dentist seeing the patient, but only in a school-based health center, nursing facility, or community health center, only with at least 2 years of experience, and only after a dentist has authorized the services in writing.
Afterward, the hygienist must refer the patient to a dentist and can't perform a second set of services until the patient has been examined by a dentist.
Confirm current requirements with the Texas State Board of Dental Examiners.
Who regulates dental hygienists in Texas?
Dental Hygienists in Texas are regulated by the Texas 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.
Can a dental hygienist in Texas give local anesthesia without a dentist present?
No. The ADHA charts list local anesthesia in Texas at direct supervision on the Practice Act row and Direct on the Local Anesthesia row, meaning the dentist must be in the room.
Texas authorized the service in 2023, limited to infiltration injections, with a required accredited or CODA-approved course, a TSBDE-approved certification exam, and 20 hours didactic plus 12 hours clinical training.
Confirm current requirements with the Texas State Board of Dental Examiners.
Which hygiene functions in Texas require the dentist to be in the room?
Two functions on the ADHA chart carry direct supervision for Texas: local anesthesia and using lasers.
Direct supervision means the dentist must be present while the function is performed.
Eleven other functions, including oral prophylaxis, x-rays and scaling and root planing, sit at general supervision instead, where the dentist authorizes in advance but need not be present.
The chart's footnote markers did not survive extraction, so check with the Texas State Board of Dental Examiners for any condition attached to these functions.
Does the Texas 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 Practice Act chart for Texas.
Not listed means the chart records no supervision level for that function in this state — it is not the same as a stated prohibition.
What a hygienist can do around diagnosis and treatment planning in practice is governed by Texas law, so check with the Texas State Board of Dental Examiners for the current scope.
Does the chart list nitrous oxide, Botox, or vaccines for Texas hygienists?
No. Administering nitrous oxide, Botox, vaccines, and dermal fillers are not listed on the ADHA Practice Act chart for Texas, the same status as placing sutures.
Not listed means ADHA's chart records no supervision level for the function in Texas — it does not state whether the function is prohibited.
For what a Texas dental hygienist can actually perform in these areas, check current rules with the Texas State Board of Dental Examiners.
Does Texas name silver diamine fluoride in its hygiene scope rules?
No. ADHA's SDF document cites §115.2, which lets a dental hygienist topically apply drugs to the surface tissues of the human mouth or the exposed surface of human teeth — a general topical-drug provision, not a rule naming SDF.
ADHA lists supervision for this provision as Direct or General, and the quoted language does not add a training, course, or setting condition.
Confirm current SDF rules with the Texas State Board of Dental Examiners.
What supervision does Texas require for silver diamine fluoride application?
ADHA lists supervision as Direct or General for the Texas provision it places SDF under — §115.2, covering topical drug application to the mouth's surface tissues or exposed tooth surfaces.
The entry does not itself describe what either level requires procedurally, and it does not say which of the two applies in which circumstance.
It also does not add a training, course, or permit requirement.
Ask the Texas State Board of Dental Examiners which supervision type applies before a hygienist applies SDF.
