Dental Assistant Requirements in Pennsylvania: Registration, X-Ray Rules & Allowed Duties

Founder, DentistryHires
September 2026

Pennsylvania's State Board of Dentistry certifies one dental-assistant credential, the expanded function dental assistant (EFDA), who must complete an approved education program, pass a Board-acceptable written exam, and hold a certificate.

A basic assistant who doesn't perform expanded functions is not separately licensed; the chapter covers that role only as auxiliary personnel working under a dentist's supervision.

Exposing radiographs requires passing DANB's Radiation Health and Safety examination.

EFDA procedures require direct supervision, meaning the dentist is on-site, personally authorizes the work, and evaluates it before the patient leaves.

The one dental-assistant credential Pennsylvania certifies

πŸ“œ Β§ 33.101

The chapter licenses dentists and dental hygienists and separately certifies expanded function dental assistants; only a certificate holder may practice as an EFDA in the Commonwealth.

It defines a broader category, auxiliary personnel, as anyone who performs dental supportive procedures under a dentist's general or direct supervision, but that category is not itself a licensed or certified title.

(a) Only persons holding a current license issued by the Board may practice dentistry or may practice as a dental hygienist in this Commonwealth. (b) Only persons holding a certificate issued by the Board may practice as an expanded function dental assistant in this Commonwealth.

Becoming certified as an expanded function dental assistant

πŸ“œ Β§ 33.102(c), Β§ 33.103(c), Β§ 33.3

A candidate for EFDA certification must show graduation from a Board-approved EFDA program at a 2-year college offering an Associate Degree, graduation from a dental hygiene school with at least 75 hours of clinical and didactic instruction in restorative functions, or completion of a Board-approved EFDA certificate or diploma program with at least 200 hours of clinical and didactic instruction, then pass a written examination acceptable to the Board.

The application fee was $110 effective November 5, 2022, rising to $120 on July 1, 2025 and $132 on July 1, 2027.

Separately, the biennial renewal fee is $31 for the April 1, 2023-March 31, 2025 period, $37 for the 2025-2027 renewal period, and $44 for the 2027-2029 period and thereafter.

(c) Expanded function dental assistants. Candidates for certification shall pass a written examination acceptable to the Board.

What direct supervision means for an EFDA

πŸ“œ Β§ 33.1, Β§ 33.205a(c)

The chapter's general definitions distinguish direct supervision, where the dentist examines the patient, authorizes the procedure, and is physically present and available in the facility, from general supervision, where the dentist need not be physically present.

For expanded function dental assistants specifically, the practice section defines direct supervision more narrowly: the dentist must be in the office, personally diagnose and authorize the procedure, remain in the office while it is performed, and personally evaluate the completed work before the patient is dismissed.

Direct supervision means that a dentist is in the dental office or treatment facility, personally diagnoses the condition to be treated, personally authorizes the procedure and remains in the dental office or treatment facility while the procedure is being performed by the expanded function dental assistant, and, before dismissal of the patient, personally evaluates the work performed by the expanded function dental assistant.

Services an expanded function dental assistant may perform

πŸ“œ Β§ 33.205a(a)

Under direct supervision, an EFDA may place and remove rubber dams, matrices and wedges; apply cavity liners and bases; place and condense amalgam restorations and carve and contour them; place and finish composite resin restorations or sealant material; perform coronal polishing as defined in the chapter; perform fluoride treatments including fluoride varnish; and take impressions of teeth for study models, diagnostic casts or athletic appliances.

Every one of these services must be performed under the dentist's direct supervision.

(2) Each of the professional services identified in paragraph (1) shall be performed under the direct supervision of a dentist.

Taking x-rays

πŸ“œ Β§ 33.301, Β§ 33.302(c)

The chapter's own EFDA scope-of-practice list does not include exposing radiographs; radiography is governed separately for auxiliary personnel generally.

Auxiliary personnel who have passed the radiologic procedure examination the Board has adopted β€” defined as the Radiation Health and Safety examination administered by DANB β€” may perform radiologic procedures on the premises of a dentist under the dentist's direct supervision, and the dentist must be on the premises when the procedure is performed, though not required to personally observe it.

Auxiliary personnel who have passed the radiologic procedure examination adopted by the Board may perform radiologic procedures on the premises of a dentist under the direct supervision of a dentist. The dentist shall be on the premises when a radiologic procedure is performed, but is not required to personally observe performance of the procedure.

What an expanded function dental assistant may not do

πŸ“œ Β§ 33.205a(b)

The chapter lists procedures an EFDA may never perform: complete or limited examination, diagnosis and treatment planning; surgical or cutting procedures of hard or soft tissue; prescribing drugs, medicaments or work authorizations; final inspection and approval of restorative work and necessary occlusal adjustments; pulp capping, pulpotomy and other endodontic procedures; placement and intraoral adjustment of fixed and removable prosthetic appliances; administering local anesthesia, sedation, nitrous oxide analgesia or general anesthesia; and taking impressions other than for study models, diagnostic casts or athletic appliances.

(b) Prohibitions. An expanded function dental assistant may not perform the following procedures: (1) Complete or limited examination, diagnosis and treatment planning. (2) Surgical or cutting procedures of hard or soft tissue. (3) Prescribing drugs, medicaments or work authorizations.

Sedation and nitrous oxide

πŸ“œ Β§ 33.205a(b)(7), Β§ 33.340(a)(3)

An expanded function dental assistant is barred outright from administering local anesthesia, parenteral or inhalational sedation, nitrous oxide analgesia or general anesthesia.

Separately, for a dentist's sedation permit, auxiliary personnel who assist in administering general anesthesia, deep sedation or conscious sedation must be trained for the duties delegated to them, perform only under the permitholder's direct on-premises supervision, not go beyond the scope of the permitholder's authority, and hold current BLS certification; they may not perform duties that require the permitholder's own professional judgment or that involve actually administering the anesthesia or sedation.

(3) Auxiliary personnel who assist the permitholder in the administration of general anesthesia, deep sedation or conscious sedation: (i) Are trained to perform the duties that the permitholder delegates to them, if the duties do not require the professional judgment and skill of the permitholder and do not involve the actual administration of general anesthesia, deep sedation or conscious sedation. (ii) Perform their duties under the direct on-premises supervision of the permitholder, who shall assume full responsibility for the performance of the duties. (iii) Do not render assistance in areas that are beyond the scope of the permitholder's authority. (iv) Are currently certified in BLS.

Continuing education for an EFDA

πŸ“œ Β§ 33.401(a)(3), Β§ 33.401(h), Β§ 33.402(g)

An expanded function dental assistant must complete 10 hours of continuing education each biennial period, compared with 30 for dentists and 20 for dental hygienists, and 2 of those hours must be in approved child abuse recognition and reporting courses.

Unless exempt, an EFDA must also complete 3 of the 10 hours in coronal polishing, in a hands-on clinical course rather than video, online or distance education; assistants who are also licensed dental hygienists, or who completed coronal-polishing coursework in a Board-approved EFDA program after June 28, 2010, are exempt from that specific requirement.

(3) Expanded function dental assistantsβ€”10 hours.
