Texas RDA Registration: Step-by-step guide for new hires

What is an RDA in Texas?

In Texas, a Registered Dental Assistant (RDA) is a dental assistant who has completed approved training and registered with the Texas State Board of Dental Examiners (TSBDE). Registration is required for any dental assistant who takes radiographs (X-rays), monitors nitrous oxide, performs coronal polishing, or assists in certain surgical procedures.

If you only do front-desk or basic chairside work, you don't strictly need RDA status — but every East Texas office we know prefers hiring registered RDAs because they can do more.

The 5-step registration process

1. Complete an approved RDA training program — PDA's RDA program (In-Person or Online) qualifies. Programs must include the required hours of radiology, infection control, jurisprudence, and clinical skills.
2. Pass the Texas Jurisprudence Assessment — an online exam covering Texas dental laws and ethics. Free practice tests are available.
3. Submit your application to TSBDE with proof of training, photo ID, and background check. We help PDA students with this step.
4. Pay the registration fee — currently $86 (TSBDE may adjust).
5. Receive your RDA certificate in the mail. You can begin working in expanded roles immediately.

What training hours does Texas require?

• Radiology certification — required minimum hours covering dental radiology theory + supervised practice. PDA delivers this in weeks 5–6.
• Infection control — OSHA-compliant infection control + bloodborne pathogen training.
• CPR / BLS — most offices require current Basic Life Support certification.
• Jurisprudence — Texas Dental Practice Act, scope-of-practice rules, board regulations.

PDA's RDA program covers all four — same curriculum whether you attend In-Person at our Longview campus or Online from home.

Common timing questions

Can I work as a dental assistant before I'm registered?

Yes — Texas allows dental assistants to work in limited capacities while training. You just can't take X-rays or do RDA-restricted tasks until your registration comes through.

How long does the registration take to come back?

Typically 3–6 weeks after TSBDE receives a complete application.

Do I need to renew?

Yes. Renewal is every two years, with continuing education hours required.

What PDA students can expect

By the end of your 12-week (or 24-week) program at PDA, you'll have:

• Completed all required training hours
• Passed practice jurisprudence exams
• Earned your radiology certification
• Practiced infection control + CPR/BLS
• Logged hundreds of hours on real practice management software
• A complete application packet ready to submit to TSBDE

We don't hand you the certificate — only TSBDE does. But we make sure that when you walk out of PDA, every box is checked and your packet is ready to submit the next day.
