Dental assistant credentials vary more than any other dental license. Pennsylvania certifies EFDAs but licenses no general assistants. Texas registers RDAs with a jurisprudence assessment, fingerprints and an x-ray certificate. California licenses RDAs through set pathways and a combined written and law exam. New York certifies registered dental assistants for $45 plus $50 every three years.
For dentists and hygienists, the question in a move is how to get the new license. For dental assistants, the first question is whether the new state has a credential at all, and if it does, which duties it controls. The answers are so different that DANB, the Dental Assisting National Board, publishes a separate chart for every state and warns that "some states' dental practice acts outline very specific allowable functions, while others outline only prohibited functions and some contain minimal or no regulation of dental assisting duties."
That matters most to DSOs and group practices that move assistants between offices in different states. An expanded-function assistant in one state may be an entry-level assistant across the border until the new state's credential issues.
How does Pennsylvania regulate assistants and EFDAs?
According to DANB's Pennsylvania chart (updated July 16, 2026), the Pennsylvania State Board of Dentistry "does not issue licenses for the practice of general dental assisting functions." A dentist may assign tasks that do not require the skill of a dentist, hygienist or EFDA to a "competent person" under direct supervision. Expanded functions, such as placing and condensing amalgam, placing and finishing composite restorations and sealants, coronal polishing and placing rubber dams, require state certification as an Expanded Function Dental Assistant.
To become certified, an applicant completes a qualifying program (a board-approved associate degree EFDA program, a CODA-accredited hygiene program with at least 75 hours of restorative instruction, or a board-approved certificate program of at least 200 hours), applies to the board, passes a board-acceptable written exam, and completes 3 hours of child abuse recognition training. For assistants certified in another state, the board's licensure snapshot says certification by criteria approval is granted "only to applicants whose licensing boards confirm that they reciprocate with the Commonwealth," with Act 41 endorsement as an alternative for those who have practiced at least 2 of the last 5 years. Pennsylvania also requires the DANB Radiation Health and Safety exam before assistants take x-rays; see our radiography guide.
What does Texas require for a Registered Dental Assistant?
DANB's Texas chart (updated May 4, 2026) lists three levels: dental assistant, dental assistant qualified to perform expanded functions, and Registered Dental Assistant. A basic Texas assistant has no education requirement. Pit and fissure sealants require two years as an assistant, current BLS and at least 8 hours of approved training; coronal polishing requires a CODA-accredited program or 8 hours of approved training. To become an RDA, a person must:
- hold a high school diploma or GED;
- complete a hands-on BLS course;
- complete the board's mandatory course covering x-ray positioning and exposure and infection control, or hold DANB's CDA certification;
- pass the TSBDE Jurisprudence Assessment within one year before applying;
- complete an approved human trafficking prevention course;
- apply for the RDA x-ray certification; and
- submit fingerprints.
Monitoring nitrous oxide requires a separate Nitrous Oxide Monitoring permit after 8 hours of approved training.
Which pathways lead to a California RDA license?
The Dental Board of California licenses RDAs and RDAs in Extended Functions and issues orthodontic assistant and dental sedation assistant permits. An RDA applicant pays a $120 nonrefundable fee, documents one of the board's pathways, completes required board-approved courses (radiation safety, coronal polishing, pit and fissure sealants, infection control, the California Dental Practice Act and BLS), submits fingerprints, and passes the RDA Combined Written and Law and Ethics Examination. The pathways include a board-approved RDA program, at least 15 months and 1,280 hours of work experience as a dental assistant, or a combination of non-board-approved education and work experience totaling 15 months and 1,280 hours. DANB also notes that California legislation in 2024 added new eligibility pathways effective July 1, 2025, including DANB's CDA certification, so confirm the current list with the board.
Who qualifies as a New York registered dental assistant?
New York's Education Law defines registered dental assisting as supportive services performed under the "direct personal supervision" of a licensed dentist, and excludes diagnosing, surgical procedures and "irreversible procedures or procedures that would alter the hard or soft tissue" (N.Y. Educ. Law § 6608). Certification requires age 18, a high school diploma, an approved course of study (a one-year program with at least 200 clinical hours, or an alternate program with at least 1,000 hours of relevant work experience), a passing exam acceptable to the department, and good moral character. The fee is $45 for initial certification and $50 for each three-year registration (§ 6608-b). A limited permit for applicants who meet everything but the exam costs $40, lasts one year and can be renewed once (§ 6608-d).
Does Florida require formal training for expanded functions?
DANB's Florida chart (updated June 16, 2026) describes on-the-job trained assistants, assistants formally trained in expanded functions, and assistants trained in restorative functions. Expanded functions require a course in a CODA-accredited program or a board-approved formal training program; DANB notes that its CDA certification stopped qualifying an assistant for expanded functions in Florida in May 2009, except for assistants grandfathered in. Restorative functions require, among other things, 2,400 hours of clinical work experience within 24 months of admission to a mandatory restorative functions course. Florida's statute also lists tasks that are "remediable and delegable" to hygienists or assistants (Fla. Stat. § 466.024).
Which records should a practice keep for each assistant?
- The state credential or permit itself, with its renewal date.
- Course certificates for each expanded function or procedure permit.
- Radiography qualification, which some states treat separately.
- BLS cards and, where required, jurisprudence or law exam results.
- For assistants moving between offices, a check of each state's rules before the first shift.
Can we handle registrations for a whole team?
Our Dental Assistant & EFDA Registration service is $149 per person. We identify the credential each state requires for the duties the assistant will perform, collect course certificates and exam results, coordinate fingerprints and give the assistant a question-by-question guide. The assistant completes, signs and submits the application and takes any exam. For multi-state groups, see license and permit compliance for DSOs.
Common questions
- Does my EFDA certificate transfer to another state?
- Not automatically. Pennsylvania, for example, certifies out-of-state EFDAs by criteria only if their licensing board confirms reciprocity, or through Act 41 endorsement after at least 2 of the last 5 years of practice. Other states may not have an equivalent credential at all.
- Do dental assistants need a license in every state?
- No. DANB notes that some states regulate assistants in detail and others very little. Pennsylvania licenses no general assisting functions, while Texas, California and New York have registered or licensed assistant credentials.
- What does a Texas RDA need?
- According to DANB's Texas chart: a high school diploma or GED, hands-on BLS, the board's mandatory course or DANB's CDA, the TSBDE Jurisprudence Assessment within a year, a human trafficking prevention course, the RDA x-ray certification and fingerprints.
- How much is a New York registered dental assistant certificate?
- The statute sets $45 for initial certification and $50 for each three-year registration. A one-year limited permit costs $40.
