Renewing depends on which credential you hold, because dental assistants answer to two systems.
DANB certification renews every year — continuing education, a current CPR certificate and a renewal fee.
State registrations and permits run on each state's own cycle with its own CE rules: California asks RDAs for 25 units every two years, Texas for 12 hours.
Here is how both clocks work, what they cost, and what happens if you miss one.
DANB renewal vs. state renewal: two clocks, not one
There is no single renewal date for a dental assistant, because the credentials come from two systems that renew separately.
DANB certification — the national credential — renews with DANB itself, every year: you complete continuing education, keep a current CPR certificate, and pay a nonrefundable renewal fee.
State registrations and permits are the second system.
They are state-issued, and each state sets its own renewal cycle, fee and CE rules.
Neither system carries the other: keeping your DANB certification current does not renew a state registration, and paying your state's renewal fee does not keep DANB certification active.
Which clock applies to you depends on what you hold.
If you are still untangling which credential your duties require — a national certification, a state registration, an x-ray or expanded-function permit, or none of these — start with the dental assistant career guide, then our DA certifications breakdown.
This page covers what happens after you hold one: keeping it.
How many CE hours do you need?
DANB's floor is 12 continuing dental education (CDE) credits a year to renew one certification, rising to 18 credits for two certifications and 24 for three (per DANB's recertification packet, October 2026).
For CDA, COA, CPFDA, CRFDA, CDPMA and COMSA renewals, the credits are not free-form: at least 2 must be in infection control and 1 in bloodborne pathogens.
State CE runs alongside that, and it varies credential by credential:
| Credential | CE required | Cycle |
|---|---|---|
| DANB certification (one held) | 12 CDE credits | Every year |
| California RDA, RDAEF, orthodontic assistant permit, dental sedation assistant permit | 25 CE units | Every two-year renewal period |
| Texas RDA | 12 hours, at least 6 clinical, plus a human trafficking prevention course | Biennial (every 2 years) |
| Pennsylvania EFDA | 10 hours, including 2 on child abuse recognition and reporting | Biennial (every 2 years) |
| Wisconsin EFDA (Expanded Function Dental Auxiliary) | 12 hours | Per renewal |
California folds its permits into one number: an RDA or RDAEF who also holds an orthodontic assistant or dental sedation assistant permit needs no CE beyond the license renewal requirement to renew the permit.
Texas's rule was last amended effective March 13, 2025 (22 Texas Administrative Code § 114.12) — so check the current text rather than an old checklist.
These are named examples, not a national standard — state CE is set by each state's own rules, and the state requirements pages carry the per-state detail.
Does your CPR/BLS certification have to stay current?
For DANB, a current CPR certificate is a renewal requirement every year, not a one-time box.
Two rules catch people out.
First, DANB accepts only hands-on CPR, BLS or ACLS from its listed providers — a fully online course does not satisfy it.
Second, CPR, BLS and ACLS do not count toward your required CDE credits, so those hours sit on top of the 12 (or more) you owe anyway.
States write CPR into their rules too, in different ways.
North Carolina requires Dental Assistant I and Dental Assistant II staff to keep an unexpired CPR certification in effect at all times while performing assisting functions — not just at renewal.
California builds BLS into license renewal itself: completing BLS certification is a mandatory course for California license renewal (16 California Code of Regulations § 1016(b)(1)).
The practical takeaway: your CPR card has its own expiry, and under the credentials above, letting it lapse can stall both renewals at once.
Renewal fees and deadlines
DANB's renewal fee for one certification is $75 a year, rising to $90 for two and $110 for three, with the credit requirement climbing the same way — 12, 18, then 24 CDE credits.
Those figures come from DANB's recertification packet current as of October 2026; fees change, so treat them as dated.
A late fee is added after the expiration date.
State deadlines do not follow one calendar.
North Dakota registrations (RDA, QDA and QDA-LRR) must be renewed by December 31 of even-numbered years.
Maine splits odd from even: dentist licenses renew every two years on December 31 of odd-numbered years, while dental hygienist and EFDA licenses run through December 31 of even-numbered years.
Arkansas expanded-duty permits must be registered with the Board on January 1 of odd-numbered years (Arkansas Code § 17-82-405).
And Texas staggers the first cycle: an RDA's first registration may be valid anywhere from 18 to 30 months, after which the Texas State Board of Dental Examiners mails a renewal reminder about 60 days before expiration.
Do not build your plan around a reminder arriving.
One audit rule is worth knowing: DANB does not require proof of CE or CPR when you renew, but it can audit — and it says certificants should keep CE records for two years.
What happens if your credential lapses?
DANB allows a grace period of three months from the date of certification expiration to complete the renewal — with the late fee attached.
After that, you are no longer DANB certified, and getting the credential back may mean retesting.
States set their own cliff edges, and some are sharper.
In Missouri, an expanded functions permit that is not renewed within one year of its expiration date is void — not suspended, void.
In North Dakota, an assistant who fails to renew by December 31 of an even-numbered year may not practice dental assisting at their registration level until they late-renew or re-register.
Working on a lapsed credential
How do you look up your renewal status?
Two lookups cover the two systems.
For DANB credentials, DANB runs an online Verify Credentials tool that confirms whether a person holds DANB's national certifications (such as the CDA), national exam certificates, or a DANB-administered state certificate in Arizona or Oregon.
For a state registration, the issuing state board is the authority — its verification system, or your account with the board, shows whether the credential is active and when it expires.
If you need the full walk-through of a formal lookup — yours or an employer's — our guide to how to look up a dental assistant license covers the per-state verification systems step by step.
Checking once a year, shortly after your renewal posts, is the cheap way to catch a processing hiccup before it becomes a lapse.
Who pays for CE — you or the practice?
The recurring cost is easy to underestimate because it stacks: DANB's $75 renewal plus 12 CDE credits a year for one certification, a hands-on CPR course on top, and — if you hold one — your state's own CE hours and renewal fee.
Whether the practice contributes is a per-practice question with no across-the-board answer, so ask before you assume it is covered: which credential the role actually requires, who pays the renewal fees, and whether CE time is paid time.
Employers weigh the same question from the other side — how to budget for staff CE and what to put in writing.
Our CE allowances (employers) guide explains how practices structure that; it is useful background before you negotiate yours.
This page is general career information, not legal advice. Renewal cycles, CE hours and fees are set by DANB and by state dental boards, and they change — confirm your own deadlines with DANB or your state dental board.
