Hiring a Dental Assistant

Dental assisting is one of the most accessible clinical roles in the practice — many states let someone start with on-the-job training and no prior credential.

That accessibility is also why the credential picture is easy to get wrong: what a given candidate is legally allowed to do depends on a mix of a national certification and state-specific titles that sound alike but are not the same thing.

The Dental Assisting National Board's CDA is a national certification.

Separately, states use their own titles — RDA, LDA, or a state-issued credential that is also sometimes called "CDA" — and those are not interchangeable with DANB's certification or with each other.

Do not try to untangle this from scratch in a job posting; our CDA vs. RDA guide covers exactly which credential is which.

The permit employers most often forget to check is radiography.

Taking x-rays is state-regulated and usually requires its own permit or exam — commonly DANB's RHS component — separate from any assisting credential.

A candidate can be a fully certified CDA and still not be authorized to take x-rays in your state without it.

See can a dental assistant take x-rays before assuming.

Verify the DANB CDA directly with DANB if a candidate claims it — it is a portable national certification, not a state authorization to practice on its own.

Separately, check whether your state requires its own registration, certification, or licence (commonly called RDA or LDA), and verify that with your state dental board by name, not by résumé claim.

Confirm the radiography permit specifically.

It is issued and tracked separately from any assisting credential in most states, and it is the permit most likely to lapse or not transfer when someone moves states.

See CDA vs. RDA for how the national and state pieces relate before you assume one implies the other.

If the role involves expanded functions — coronal polishing, sealants, or restorative placement where the state allows it — verify the specific expanded-function permit too.

States name these differently (EFDA, RDAEF, and others) and they are credentialed separately from basic assisting.

The national median is $48,070, with the middle 50% between $44,340 and $58,090 (BLS OEWS, SOC 31-9091, May 2025).

Budget from your own state's figure where one is published — see the state table — the spread between states is substantial.

Most dental assistants are paid hourly, so the annual figure is an annualisation at full-time hours.

Certification and expanded-function permits tend to move pay toward the upper end of the range, though BLS does not publish a separate wage for certified versus uncertified assistants, so there is no fixed premium percentage to quote.

Specialty settings — oral surgery, orthodontics, pediatrics — and busy group practices or DSOs commonly pay more than a small general office, and expanded-function roles command a premium over basic chairside assisting.

State the schedule and pay basis in the first few lines.

Most dental assistants are paid hourly, and a listing that hides the schedule or the rate reads as a listing with something to hide.

Name the credential precisely — "DANB CDA preferred" is not the same requirement as "active [STATE] registration," and a candidate reading a vague listing cannot tell which one you actually need.

If x-rays are part of the job, say so explicitly and require the radiography permit by name.

Do not list duties your state does not permit an assistant to perform without an expanded-function permit — coronal polishing, sealants, and restorative work are commonly gated behind a separate credential.

A listing that assumes otherwise tells a credentialed candidate you have not checked.

Confirm the DANB CDA (if claimed), any state registration, and the radiography permit are all active before day one — and keep the verification record.

These are checked separately; one does not vouch for the others.

Give a new assistant a lighter first week focused on your sterilization protocol, tray setups, and where things live.

The cost of a slower first week is trivial against the cost of a hire who leaves because they never found their footing.

Be explicit about who they'll be chairside with most, how radiographs get reviewed, and what to do when the schedule slips.

Ambiguity on those three is a common reason a competent assistant does not stay past the first few months.
