A felony does not create a blanket California ban on dental-assistant work. The first question is whether you mean an unlicensed dental assistant working under a dentist’s supervision or a registered dental assistant (RDA) applying for a state license. California permits the first role without an RDA license, but limits its duties. An RDA applicant is reviewed by the Dental Board of California under conviction-specific rules; a prior felony does not automatically decide that application. A dental office’s hiring decision is separate from the Board’s license decision. (Business and Professions Code §§1750, 1750.1, 480)
| Your situation | The decision that matters |
|---|---|
| Seeking an unlicensed assistant job | Ask what procedures the dentist expects you to perform, what training they require, and whether the employer will hire you. Section 480’s license-denial test does not decide an ordinary employment offer. |
| Applying for an RDA license | The Board fingerprints applicants and assesses a conviction under the initial-licensure rules. The offense, its relation to RDA duties, dates, and any record relief matter. |
| Already holding an RDA license | Renewal disclosure and possible discipline are separate from a first-time applicant’s denial rules. |
What an unlicensed assistant may do
An unlicensed dental assistant may perform basic supportive procedures under a licensed dentist’s supervision. The dentist determines competency; the employer must ensure a qualifying infection-control course or examination before duties involving potential exposure to blood, saliva or other infectious material. The statute also requires specified Dental Practice Act instruction and current basic-life-support certification within one year of first employment with that employer. The allowed work has boundaries: section 1750.1 lists supervised duties and reserves others, including pit and fissure sealants, for registered or other authorized professionals. (Sections 1750, 1755(b))
There is a narrow exception for coronal polishing before RDA licensure. Under section 1750(f)(4), the unlicensed assistant must complete a Board-approved coronal-polishing course; before that course, the assistant must have completed a Board-approved eight-hour infection-control course and hold current basic-life-support certification. The polishing must follow the dentist’s order and direct supervision, the dentist must evaluate the patient afterward, and the coronal-polishing course certificate must be displayed at the treatment facility. The separate infection-control examination option for basic duties does not replace this eight-hour prerequisite. Do not assume that this exception authorizes other RDA-only duties. (Sections 1750(f)(4), 1755(b))
If you seek an RDA license
California has several routes to RDA licensure, including approved education or qualifying dental-assistant work experience. Applicants must meet course, basic-life-support and examination requirements and submit fingerprints for a criminal-history check. The Board’s RDA applicant instructions and section 1752.1 describe those requirements. Working as an unlicensed assistant can be part of an RDA eligibility route, but employment alone does not confer the RDA license.
For a denial based on conviction history, section 480(a)(1) requires a substantial relationship between the conviction and license duties and generally a conviction within seven years before application, current incarceration for the crime, or release from incarceration within that seven-year period. The seven-year limit does not apply to a serious felony as defined in Penal Code §1192.7 or an offense requiring registration under the specified parts of Penal Code §290(d)(2) or (3); substantial relationship still must be assessed. Section 480 has a separate older-financial-crime exception for certain fiduciary licenses, but it does not list dental assisting. The Dental Board’s applicant guidance explains its individualized relationship and rehabilitation review.
A pending charge is not itself a conviction under section 7.5. A guilty or no-contest plea can become a licensing conviction when the statutory conditions are met, including when an order grants probation while suspending imposition of sentence. Before agreeing to a plea, review the precise offense and proposed disposition rather than assuming the charge label settles the Board question. (Sections 7.5, 480)
For an initial RDA application, the Board may not require you to list or supply criminal-history documents, though it may request voluntary mitigating information. Fingerprinting still permits background review. Section 480 protects qualifying dismissed convictions and recognizes a certificate of rehabilitation, pardon, clemency, or a showing of rehabilitation; the exact order and dates matter, and none waives unrelated licensing requirements. An arrest that ended in a disposition other than conviction cannot itself be the basis for denial under that section. (Section 480(b)–(f); Board applicant guidance)
If you already hold an RDA license, the Board’s renewal instructions require disclosure of criminal convictions and other-license discipline since the last renewal. That is different from the initial application’s criminal-history disclosure rule; the Board page does not establish a general deadline to report every arrest.
