Dental assistants work in close contact with patients, handle sharp instruments, prepare and sometimes monitor nitrous oxide, take radiographs, and have routine access to protected health information and billing records. Some states address that risk by registering or certifying dental assistants with a criminal history question or a fingerprint based background check. Many states do not regulate the role at all, or only regulate the expanded functions, such as taking x rays or placing sealants. Because the rules are inconsistent, dental practices generally run their own screening on top of whatever the state requires, and employers should not assume a background check happened just because a state issued a certificate.
How states treat the dental assistant role
Dentistry is licensed at the state level, and each state dental board decides whether dental assistants need a credential at all. Three broad patterns show up across the country.
- A state requires no registration or permit for a general dental assistant, and only regulates assistants who perform expanded functions such as exposing radiographs, placing temporary restorations, or administering nitrous oxide monitoring.
- A state issues a registration or certificate to dental assistants who want to perform those expanded functions, and ties that credential to a criminal history review, sometimes with fingerprinting through the state and federal systems.
- A state requires dental assistants to pass an accredited program or a national exam before performing expanded duties, but does not run a fingerprint based check at all.
Because the pattern varies this much, the only reliable way to know what a specific state requires is to check that state’s dental board directly rather than assume every state follows the same model.
Two states that fingerprint dental assistant applicants
California and Texas both confirm, on their dental board sites, that dental assistant applicants go through a fingerprint based criminal history check, not just a registration form.
In California, an applicant for a Registered Dental Assistant credential must submit fingerprints through the state’s Live Scan program for a background check cleared by both the California Department of Justice and the Federal Bureau of Investigation before the Dental Board of California will issue the credential.
Texas takes a similar approach but applies it more broadly. The Texas State Board of Dental Examiners states plainly that criminal background checks are performed on all dentist, dental hygienist, and dental assistant registration applicants for licensure in the state, cleared through the Texas Department of Public Safety and the FBI based on the applicant’s fingerprints.
These two examples do not mean every state follows the same rule. Some state boards ask a criminal history question on the application without requiring fingerprints, and others leave dental assistants entirely unregulated. An employer in a state that does not fingerprint dental assistants should not assume a state check already happened and should instead treat its own screening as the primary safeguard.
| Element | California | Texas | States without a dental assistant credential |
|---|---|---|---|
| State credential required | Yes, for Registered Dental Assistant status and expanded functions | Yes, registration for dental assistants performing certain duties | No state credential for the general assistant role |
| Fingerprint based criminal history check | Yes, Live Scan cleared through state and federal databases | Yes, cleared through the state public safety agency and the FBI | Not applicable at the state level |
| Who confirms the result | Dental Board of California | Texas State Board of Dental Examiners | No state board tracks this population |
| What this means for an employer | Verify the registration is active and unrestricted | Verify the registration is active and unrestricted | Run a full employer background check since no state filter exists |
What employers typically screen beyond the state credential
Because state regulation of dental assistants is inconsistent, most dental practices build their own screening process around the specific risks of the job: patient contact, instrument and medication access, and billing exposure.
Criminal history
A criminal background check through a consumer reporting agency remains the most common screening step regardless of whether the state requires one. Employers look at convictions relevant to patient safety, theft, or violence, consistent with their own hiring policy and applicable state law. Many states limit how far back an employer can consider certain records or require an individualized assessment before taking action, so a flagged record should prompt a documented review rather than an automatic decision. Employers evaluating arrest or conviction history should also be familiar with the Equal Employment Opportunity Commission’s guidance on considering arrest and conviction records in employment decisions, which describes how blanket exclusions can create discrimination risk and why a job related, individualized review is generally the safer approach.
Federal healthcare exclusion screening
Dental practices that bill Medicare, Medicaid, or other federal health care programs cannot knowingly employ someone who is excluded from those programs, even in a support role like a dental assistant. The Office of Inspector General for the Department of Health and Human Services maintains the List of Excluded Individuals and Entities and advises that health care entities should routinely check the list for new hires and current employees to avoid civil monetary penalty exposure. This check is separate from a criminal background check and should be run on its own, ideally at hire and again on a recurring basis for staff who remain employed.
License or registration verification
Where a state does register or certify dental assistants, an employer should verify that the credential is current, matches the person presenting it, and carries no discipline or restriction, by checking the issuing board’s public license lookup rather than relying on a photocopy the applicant provides.
Immunization records
Dental assistants are routinely exposed to blood, saliva, and other potentially infectious material while assisting chairside, which is why the federal bloodborne pathogen standard requires covered employers to make the hepatitis B vaccine series available to employees with occupational exposure. The Occupational Safety and Health Administration’s bloodborne pathogens standard sets that obligation at the federal level, and many dental employers build their own immunization documentation request around it, asking for proof of hepatitis B vaccination or a signed declination, along with other immunizations the practice considers appropriate for a clinical setting.
Drug testing
Because dental assistants may handle controlled substances such as nitrous oxide or have access to medication samples and prescription pads in some practices, some employers include a pre employment drug test as part of onboarding. Testing policies and what a positive result means for an applicant vary by employer and by state law, particularly where state marijuana laws intersect with workplace policy, so employers generally consult counsel before finalizing a testing and consequence policy rather than assuming one approach applies everywhere.
Running the background check under the Fair Credit Reporting Act
When an employer uses a third party consumer reporting agency, rather than checking records itself, the screening has to follow the federal Fair Credit Reporting Act process. That generally means giving the applicant a clear, standalone disclosure that a background check will be obtained, getting written authorization before ordering the report, and, if the employer is considering not hiring based on what the report shows, sending a pre adverse action notice with a copy of the report and a summary of rights before making a final decision, followed by an adverse action notice if the employer proceeds. The permissible purpose and procedural requirements sit in 15 U.S.C. 1681b, and the implementing rules that consumer reporting agencies and employers must follow are set out in Regulation V at 12 CFR part 1022. These steps apply regardless of whether the state also runs its own fingerprint check, because the state credential process and an employer’s consumer report are two separate legal obligations that do not substitute for each other.
A background check does not automatically surface every past record. State sealing and expungement laws, reporting time limits that vary by state, and differences in what a given court or agency makes publicly searchable all affect what shows up, so an employer should treat the report as one input rather than a promised full history.
Dental practices that want a single screening partner to coordinate the criminal history check, verification steps, and FCRA paperwork can review how Reveal Background structures employment screening for healthcare and patient facing roles.
For practices building a broader hiring checklist, two related roles are worth comparing. Dental hygienists are licensed in every state, unlike dental assistants, and that licensing process is described in this overview of dental hygienist license background checks. Practices that bill federal health programs and want a closer look at how the exclusion check works day to day can also read this explanation of OIG and SAM exclusion screening.
Frequently asked questions
Do all states require dental assistants to be fingerprinted?
No. Fingerprint based criminal history checks for dental assistants are confirmed in states such as California and Texas, but many states do not regulate the general dental assistant role or do not require fingerprinting for it. Employers should confirm the specific rule with the dental board in the state where the practice operates rather than assume a national standard.
Does a dental assistant need a license to work?
Not always. Many states allow a dentist to train and supervise a dental assistant without a state license for routine chairside duties, while reserving a registration, certificate, or permit for expanded functions such as taking radiographs or placing sealants. Whether a credential is required depends entirely on the state and the specific duties the assistant performs.
Why would a dental practice need to check the OIG exclusion list for a dental assistant?
Any practice that bills Medicare, Medicaid, or another federal health care program can face civil monetary penalties for employing someone on the exclusion list, even in a non billing support role. The Office of Inspector General advises health care entities to check new hires and current staff against the list routinely, not only at hiring.
Can a dental practice require a drug test for a dental assistant applicant?
Many employers can require pre employment drug testing as a condition of hire, subject to the employer’s own policy and applicable state law. Because dental assistants may have access to controlled substances or medication samples in some practices, employers often include this step, but testing and consequence policies should be reviewed with counsel given how state laws on this topic vary.
What is the difference between a state dental board check and an employer background check?
A state dental board credential check, where one exists, confirms whether a specific state ran its own fingerprint or criminal history review before issuing a registration. An employer background check is a separate process the hiring practice runs, usually through a consumer reporting agency, and it is not replaced by the state process even in states that do fingerprint applicants.
Does a background check promise that a dental assistant has no criminal history?
No report can promise a complete history. What a background check shows depends on state reporting and sealing rules, how far back an employer is permitted to look, and which records are searchable in the jurisdictions checked, so results should be treated as one part of the hiring decision rather than a complete promise.
