There is no RDA-specific pay figure: BLS counts registered and unregistered dental assistants in one occupation, and no salary survey we found splits an RDA premium out of the occupation total.
In May 2025, BLS put the median for all U.S. dental assistants at $23.11 an hour ($48,070 a year).
The closest credential split our research found is DANB certification, not state registration.
Here is what the data does show, including the states where the RDA title exists.
Typical RDA pay range
BLS OEWS does not publish a registered-dental-assistant series.
In May 2025 it counted every U.S. dental assistant — registered or not — in one occupation (SOC 31-9091), with a median of $23.11 an hour, or $48,070 a year.
The middle half of those assistants earned between $21.32 and $27.93 an hour ($44,340 to $58,090 a year).
The lowest-paid 10% earned under $17.85 an hour ($37,130 a year), and the top 10% earned over $29.93 an hour ($62,250 a year).
Posted pay is a separate series.
Dental practices hiring dental assistants on DentistryHires posted a median of $23.50 an hour across 1,305 employers and 2,651 listings that stated hourly pay (October 6, 2026), and the middle half of those listings offered $21.00 to $26.00 an hour.
That is posted pay, not take-home earnings — and it is not split by credential either, because the published listing data covers dental assistants as one group.
Neither figure is RDA-specific.

RDA vs unregistered DA
The honest answer first: neither the federal wage series — which counts registered and unregistered assistants in one occupation — nor the large salary surveys we found puts a dollar figure on the RDA premium.
The only large credential split our research found is DANB's 2026 survey, which reports certification (CDA vs non-CDA), lead status and restorative functions — not state registration.
What registration can change is what you are allowed to do.
BLS notes that states typically do not require a license for entry-level dental assisting, though some require assistants to be licensed, registered or certified for entry or advancement — for example, to take radiographs or handle infection control.
In California the reserved-duties effect is explicit: pit and fissure sealants may be placed only by an RDA, RDAEF, RDH or RDHAP — not by an unlicensed assistant — and a registered dental assistant may perform mouth-mirror inspections and charting, and polish coronal surfaces, under general supervision.
The title alone is not a skills signal everywhere.
Kentucky does not recognize EDDA or EFDA titles, and "Registered Dental Assistant (RDA)" there only means the assistant was registered by an employer dentist — it does not imply special training.
So where a state reserves duties for the credential, there is more reserved work to price; where registration is administrative, the letters alone may not move pay.
Whether that translates into pay is not measured: no sourced figure ties reserved duties to a pay premium.
Our page on what an RDA is covers how far the definition moves state to state.
RDA vs RDAEF
RDAEF — Registered Dental Assistant in Extended Functions — is California's expanded-function tier.
States name the level differently: Pennsylvania uses "expanded function dental assistant" (EFDA), Ohio uses "expanded function dental auxiliary," and California uses RDAEF.
The RDAEF license sits on top of the RDA in California: it requires a current RDA license, fingerprints, a board-approved extended functions program, current BLS certification, a pit and fissure sealant course, and a written exam.
An RDAEF licensed on or after January 1, 2010 may, under direct supervision, place, contour, finish and adjust all direct restorations, take final impressions for permanent indirect restorations, perform post, core and build-up procedures, and size, fit and cement endodontic master points.
There is no RDAEF wage series to quote — BLS counts every assistant in SOC 31-9091.
The closest sourced figure is DANB's 2026 survey: assistants who perform restorative functions reported $28.93 versus $28 an hour among CDAs, and $24 versus $23.50 among non-certified assistants — under a dollar an hour in both pairs.
Treat any "RDAEF salary" figure you see elsewhere as unverified.
See EFDA pay for what the expanded-function data does show.
Pay by RDA state
State medians for all dental assistants (BLS OEWS, May 2025) span a wide band.
Minnesota had the highest state median, $31.38 an hour ($65,270 a year); the next highest annual medians were District of Columbia $60,580, Maine $60,070, New Hampshire $59,530, and Oregon $59,490.
DentistryHires posted-pay data (October 6, 2026) points the same direction: Minnesota led at $31.50 an hour across 52 listings, followed by Massachusetts and Oregon at $27.50, and California, Washington and New Jersey at $26.00 each.
Texas posted $20.00 an hour across 300 listings.
Minnesota is also a state that licenses dental assistants — an applicant must have graduated from a dental assisting program accredited by CODA and pass the board-required exam, including Minnesota dental law.
Both series measure all assistants in each state, registered or not, so read these as market levels, not registration premiums.
How to negotiate with the credential
Negotiate from duties, not from the letters.
The case with evidence behind it is the reserved work itself: in California, pit and fissure sealants are limited to RDAs, RDAEFs, RDHs and RDHAPs, and an RDA may chart and polish under general supervision; in Texas, positioning or exposing x-rays requires the state radiology certificate; and a California RDAEF can place, contour, finish and adjust all direct restorations under direct supervision.
Name the specific functions you perform and the supervision they free up for the dentist.
Anchor the number on live data.
The DentistryHires employer median posted pay for dental assistants was $23.50 an hour, with the middle half of listings between $21.00 and $26.00 (October 6, 2026), and the state medians above show how wide the spread is.
Employers setting a band can see the same picture in our DA salary guide (employers).
Short answer: RDA pay vs unregistered DA
No sourced number we found says an RDA makes $X more than an unregistered assistant — BLS splits no RDA pay out of the dental-assistant total, whose national median was $23.11 an hour in May 2025, and the salary surveys we read split DANB certification, not registration.
What is measured: DANB-certified assistants reported $28 an hour against $24 for non-certified in DANB's own 2026 survey.
The route by which registration could move pay is duties: states reserve some work — placing sealants in California, for example — to credentialed assistants, and no survey we found prices that link.
If your state's registration unlocks reserved work, make the case on the work; if it is administrative, the letters alone may carry little weight.
Which states have an RDA credential
DANB's own summary is a clean frame: some states use the EFDA title for the expanded-function level, while DANB notes others use titles such as Licensed Dental Assistant (LDA), Registered Dental Assistant (RDA) or Registered Dental Assistant in Extended Functions (RDAEF).
The same title can therefore mean a full license in one state, an x-ray qualification in another, and an employer registration step in a third.
These named states from our sourced fact base show the spread:
| State | What "RDA" means there |
|---|---|
| California | A license with five entry routes, including a board-approved RDA program, 15 months and at least 1,280 hours of work experience, or current DANB CDA certification. |
| Texas | The Dental Assistant Radiology Certificate, issued as an RDA — required to position or expose dental x-rays; not an expanded-function credential. |
| New York | A protected title: only a person certified under the state's education law may practice registered dental assisting or use the title. |
| Michigan | A state license — the board's guide says the RDA license allows the holder to engage in the practice of dental assisting. |
| Minnesota | Licenses dental assistants, but the state uses Licensed Dental Assistant (LDA) rather than the RDA title. |
| North Dakota | One of five recognized levels, alongside QDA, QDA-Limited Radiology Registrant, Dental Anesthesia Assistant and unregistered assistant. |
| South Dakota | Registration as an RDA is required before performing expanded functions. |
| New Jersey | "Registered Dental Assistant" and "Limited Registered Dental Asst (orthodontics)" are searchable license types. |
| Iowa | A registration prefix: RDA means registered without a radiography qualification, distinct from QDA (registered with radiography) and XDA. |
| Washington | Registered through the Department of Health; dentists may delegate radiographs to registered assistants under close supervision once competence is shown. |
| Vermont | Since October 15, 2025, no one may practice as a dental assistant unless registered, in a traditional or DANB-certified category. |
| Arkansas | An assistant holding an expanded-function permit is considered a Registered Dental Assistant, and the permits must be displayed in the office. |
| Tennessee | An RDA must hold board-issued certifications before performing coronal polishing, radiology, nitrous monitoring, sealants, prosthetic or restorative functions. |
| Kentucky | "RDA" only means the employer dentist registered the assistant — no special training implied — and the state does not recognize EDDA or EFDA titles. |
Registration does not transfer automatically between states: credentials are state-issued and each state sets its own requirements, so verify with the board where you plan to work.

Titles and rules are state law
RDA vs CDA pay
The CDA is a different credential from an RDA: it is the Dental Assisting National Board's national certification, not a state registration.
The sourced comparison we have comes from DANB itself: in its April 2026 survey — a 3% response rate from invitations sent to over 50,000 dental assistants, reporting median hourly pay excluding benefits — DANB Certified Dental Assistants reported median pay of $28 an hour versus $24 for non-certified assistants, a $4 (17%) difference.
Read that with care.
DANB sells the CDA credential, and the survey measures certification rather than state registration: a CDA in a registration state still holds whatever state credential that state requires, and a Texas RDA may hold no DANB certification at all.
They can connect: in California, current DANB CDA certification is one of the five routes to the RDA license.
For the certification question on its own terms, see CDA pay premium; for how employers weigh credentials against chairside training, see certified vs trained assistants.
RDA pay in California and Texas
California: dental assistants earned a median of $24.09 an hour ($50,110 a year) across 56,220 jobs in May 2025 — the most jobs of any state — and BLS does not split RDAs out of that figure.
California employers on DentistryHires posted a $26.00 median (October 6, 2026).
The California RDA is a full license with statutorily reserved duties: pit and fissure sealants are limited to RDAs, RDAEFs, RDHs and RDHAPs, and an RDA may chart and polish under general supervision.
Texas: dental assistants earned a median of $21.84 an hour ($45,430 a year) across 33,230 jobs, with Texas employers posting a $20.00 median (October 6, 2026).
The Texas "RDA" is a different object: the Dental Assistant Radiology Certificate from the State Board of Dental Examiners, required to position or expose dental x-rays — an x-ray registration, not an expanded-function credential.
So "registered dental assistant salary" searches in the two states above resolve to the same place: one BLS series for all assistants, with no RDA split published.
Paths from RDA to RDAEF/EFDA
In California, the step up runs through the state: RDAEF licensure requires a current RDA license, fingerprints, a board-approved extended functions program, current BLS, a pit and fissure sealant course, and a written exam — and the license adds restorative placement, final impressions, post and core, and endodontic master points, under direct supervision.
Other states build the level differently.
Maine licenses the Expanded Function Dental Assistant as a separate board license, which requires a dental assisting certificate or a hygiene license, completion of an EFDA program, and passing the required examinations.
Connecticut defines an expanded function dental assistant by exam and program rather than a state license: passing the DANB Certified Dental Assistant or Certified Orthodontic Assistant exam plus an EFDA program accredited by CODA, with the DANB certification maintained.
There is no wage series for the tier — BLS counts all assistants together — and DANB's restorative-functions split showed under a dollar an hour.
