What a Dental Hygienist Can Do in South Carolina: Permitted Functions & Supervision Levels
South Carolina's ADHA Practice Act row leans toward general supervision rather than direct access, and no function is listed at direct access (A) for this state on the chart.
Oral prophylaxis, x-rays, topical anesthesia, fluoride, pit and fissure sealants, scaling and root planing, soft tissue curettage, study cast impressions, and removing sutures sit at general supervision, where a dentist authorizes the service in advance but need not be present.
Local anesthesia, placing periodontal dressings, and removing periodontal dressings sit at direct supervision, which requires the dentist to be in the room.
Administering nitrous oxide, placing sutures, dental hygiene diagnosis, treatment planning, dental hygiene assessment, prescriptive authority, Botox, lasers, vaccines, and dermal fillers are not listed on the chart for South Carolina.
- No function on South Carolina's Practice Act chart reaches direct access (A); general supervision (G) is the highest level any function is listed at.
- Local anesthesia is listed at direct supervision (D) for South Carolina, meaning the dentist must be present, which the state's separate Local Anesthesia chart entry confirms.
- Placing and removing periodontal dressings are listed at direct supervision (D) alongside local anesthesia, the three functions on the chart that require the dentist in the room.
- Dental hygiene diagnosis, treatment planning, dental hygiene assessment, and prescriptive authority are all marked not listed on the chart for South Carolina.
- G
- General supervision: dentist needs to authorize prior to services, but need not be present
- D
- Direct supervision: dentist needs to be present

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 South Carolina Board of Dentistry.
Frequently Asked Questions
Does a dentist have to supervise a dental hygienist in South Carolina?
Not entirely — under the 2003 General Supervision provision (Sec. 40-15-110 (A) (10)), a dental hygienist employed by, or contacted through, South Carolina's Department of Health and Environment Control may provide prophylaxis, fluorides, and sealants under general supervision, without prior examination by a dentist, in settings such as schools or nursing homes, provided the hygienist carries professional liability insurance.
Outside that arrangement, this is not a blanket unsupervised-practice grant — confirm current details with the South Carolina Board of Dentistry.

Does a South Carolina dental hygienist need a dentist present to give local anesthesia?
Yes.

Confirm the current permit requirements with the South Carolina Board of Dentistry before applying.
Which South Carolina hygiene functions require the dentist to be in the room?
Three functions on the ADHA chart carry direct supervision for South Carolina: local anesthesia, placing periodontal dressings, and removing periodontal dressings.
Direct supervision means the dentist must be present while the hygienist performs the procedure.
Most other listed functions, including oral prophylaxis, x-rays, fluoride, sealants, and scaling and root planing, sit at general supervision instead, where the dentist authorizes the service in advance but does not need to be in the room.
Check with the South Carolina Board of Dentistry for any conditions attached to these functions.
Does the South Carolina chart list dental hygiene diagnosis or prescriptive authority?
No. Dental hygiene diagnosis, treatment planning, dental hygiene assessment, and prescriptive authority are all marked as not listed on the ADHA Practice Act chart for South Carolina.
Administering nitrous oxide is also not listed.
A dash on the chart means the function does not appear as permitted, which is not the same as a stated prohibition.
Contact the South Carolina Board of Dentistry to ask about the current scope of practice for these functions.
Does South Carolina's chart cover Botox, vaccines, or dermal fillers for hygienists?
No supervision level is listed for Botox, vaccines, or dermal fillers on the ADHA Practice Act chart for South Carolina, the same as dental hygiene diagnosis and prescriptive authority.
Not listed means the chart does not show the function as permitted; it is not the same as a stated prohibition, and the chart does not say why.
Ask the South Carolina Board of Dentistry directly whether hygienists in the state can perform any of these procedures.
Does South Carolina's ADHA entry name silver diamine fluoride specifically?
No. The entry ADHA published for South Carolina does not name SDF by name.
It cites §40-15-102 and quotes a single provision — scope of practice includes fluoride treatment — under which ADHA places SDF as a topical fluoride agent.
Supervision is listed as General.
The entry states no training, course, setting, permit, or collaborative-agreement condition, and lists no references beyond the cited section.
Confirm current SDF guidance with the South Carolina Board of Dentistry.
