A Registered Dental Assistant (RDA) is a licensed professional who performs supportive clinical and administrative duties within a dental practice. This designation signifies formal training and legal authorization, elevating the role beyond that of a standard dental assistant. This article explores the distinction, duties, educational requirements, and career trajectory of the RDA.
Defining the Registered Dental Assistant
The RDA designation is a formal, state-level professional classification distinct from a standard Dental Assistant (DA). Attaining the “Registered” title requires completing a recognized educational program, passing specific examinations, and securing licensure through the state’s governing dental board. This process grants the RDA legal recognition to perform a wider array of clinical procedures, defining a broader scope of practice than an assistant without registration.
While an unlicensed assistant is limited to basic supportive functions, the RDA’s registration confirms competency in more complex clinical duties. This legal authorization ensures a uniform standard of care and technical proficiency, transforming the role into a formally recognized and regulated health care profession.
Core Duties and Responsibilities
The daily work of an RDA focuses on supporting the dentist and ensuring the efficient flow of the clinical environment. This involves preparing the treatment room by sterilizing instruments, setting up trays, and ensuring materials are ready for procedures. RDAs also prepare the patient, reviewing health history, taking vital signs, and ensuring comfort during treatment.
During procedures, the RDA provides chairside assistance, operating a high-volume evacuation system, retracting tissues, and passing instruments and materials. Technical tasks include exposing and processing dental radiographs, which requires specialized training. RDAs also maintain patient records, manage inventory, and educate patients on proper oral hygiene and post-operative care.
The Path to Becoming a Registered Dental Assistant
Becoming an RDA typically begins with formal education in an accredited dental assisting program. These programs provide instruction in dental sciences, clinical procedures, and laboratory skills, often leading to a certificate or associate degree. Some states offer alternative pathways, such as completing a specified number of months or clock hours of on-the-job training under a licensed dentist.
Candidates must also complete prerequisite courses and specific certifications, including Basic Life Support (BLS), infection control, and radiation safety training. The final step involves passing a comprehensive examination, which may include a written knowledge test and a practical skills assessment specific to state requirements. Upon successful completion, the candidate applies to the state dental board to receive the RDA credential.
Expanded Functions and Specialized Skills
The Registered status grants the RDA legal authority to perform functions beyond the scope of a non-registered assistant. These “expanded functions” are regulated by state law and often require additional training or endorsements.
Common expanded duties include:
Performing coronal polishing (removal of soft deposits from tooth crowns).
Applying topical fluoride.
Taking final impressions for diagnostic models.
Placing and removing matrices and wedges for restorative procedures.
Placing temporary restorations.
In some jurisdictions, the RDA can pursue further specialization, such as the Registered Dental Assistant in Extended Functions (RDAEF) credential, which permits advanced duties like placing and finishing direct restorations. This delegation of tasks increases the practice’s efficiency.
Work Settings and Career Outlook
RDAs are employed across diverse professional environments. The majority work in general dentistry offices, supporting routine checkups, restorative procedures, and preventative care. Other common settings include specialty practices focused on orthodontics, pediatric dentistry, periodontics, and oral surgery.
The career outlook remains stable, driven by the demand for preventative dental services and an aging population. Job growth is projected to be faster than the national average. The RDA credential often correlates with a higher earning potential compared to unlicensed assistants due to the expanded range of authorized procedures.
Continuing Education and Maintaining Registration
Maintaining the RDA designation requires ongoing professional development through Continuing Education (CE). State dental boards mandate that RDAs renew their registration periodically, typically every one to three years, requiring the completion of a specific number of CE credits. These mandatory hours ensure that licensed professionals remain current with advancements in dental technology, materials, and public health regulations.
Required CE hours often include mandatory topics, such as infection control, the state’s dental practice act, and the renewal of the Basic Life Support certification. Failure to complete the necessary CE requirements by the renewal deadline can result in the registration lapsing, legally preventing the individual from practicing as an RDA until compliance is achieved.
