Expanded Functions Dental Assisting (EFDA)

Pursuing an education in Expanded Functions Dental Assisting is excellent option for dental professionals who may be looking to expand their current scope of practice and further their education in dentistry. Obtaining the unique skillset of an EFDA creates the opportunity for increased job satisfaction, earning potential, and adaptability in a dental practice.

An Expanded Functions Dental Assistant is responsible for:  placing and carving amalgam, composite and intermediate restorations; placement of dental sealants; performing coronal polishing; application of fluoride treatments; placement and removal of dental dams; placement of matrix bands and wedges; placement of bases and liners prior to tooth restoration.


About the program

The EFDA Program at HACC consists of two courses spanning over two semesters, described below. Upon successful completion of both courses and documentation of required clinical practice hours, the student will be eligible to apply for their EFDA Certification from the Commonwealth of Pennsylvania. Once the student receives approval from State Board of Dentistry, the student can register to take the Pennsylvania Expanded Functions Dental Assisting State Licensure Exam.

The Pennsylvania State Board of Dentistry requires each applicant for licensure to have a national practitioner data bank query completed within 90 days of submission to the Board. Please note: a criminal history may prevent certification/licensure as an Expanded Functions Dental Assistant. Please contact the SBOD for further information.
