What is an EFDA (Expanded Function Dental Auxiliary)?

Recently, New Hampshire passed legislation and regulations to establish a new dental workforce provider: Expanded Function Dental Auxiliary (EFDA).  An EFDA, already used in 30 states, provides assistance and additional efficiencies at dental practices and public health clinics.

According to the NH Board of Dental Examiners, to be qualified to place, contour and adjust direct restorative materials within the oral cavity, one must:

  • Meet the program pre-requisites as outlined on this web page.
  • Successfully complete a Board approved EFDA course.
  • Register as an Expanded Function Dental Auxiliary (EFDA) with the NH Board of Dental Examiners (NHBODE).
  • Work under direct supervision of a NH-licensed dentist.
  • Complete required continuing education coursework biennially.

Program Overview

The NHTI EFDA program is designed to prepare CDAs, RDHs and graduates of a CODA-accredited school of dental assisting to function efficiently and safely as an integral member of the dental team.

The successful EFDA candidate:

  • Has a positive attitude and is eager to learn
  • Enjoys new challenges and responsibilities
  • Values upward mobility in dental career
  • Is committed to the profession and continuing education
  • Communicates well with patients and the dental team
  • Handles stress well and is neat and organized
  • Follows instruction with attention to detail

Learning Objectives

  • Demonstrate effective asepsis and infection control management
  • Demonstrate effective communication skills with patients and other dental team members
  • Demonstrate the highest level of safety during treatment of each patient
  • Demonstrate knowledge and performance of restorative techniques, both amalgam and composite
  • Practice as an EFDA under the direct supervision of a NH-licensed dentist  within the legal and ethical boundaries set forth by the State of New Hampshire Board of Dental Examiners


  • 50 hours of didactic (classroom-based) instruction
  • 100 hours of pre-clinical instruction (working on mannequins in the clinic)
  • 6 weeks, minimum of 120 hours of clinical training in dental office with sponsoring dentist

The sponsoring dentist must agree to support the EFDA trainee in performing intra-oral procedures (restorations) in the office once the student has successfully completed classroom and pre-clinical instruction.

Clinical Training

After completion of the didactic and pre-clinical instruction, candidates begin the 120 hours, minimum of six weeks, of the satellite clinical experience in their sponsoring dentist/office.  The specific requirements, competencies and clinical training will be overseen by the candidate’s sponsoring dentist with support from the NHTI EFDA faculty.


EFDA candidates will have four months to complete the requirements, which, with a passing grade, would allow them to register with the NHBODE and obtain an EFDA permit from the board.  After successful completion of the 270-hour program, the EFDA dental hygienist or dental assistant shall be considered qualified to place, contour and adjust direct restorative materials within the oral cavity.
