What is an Expanded Duty Dental Assistant?

While a career in Dental Assisting is a rewarding journey in itself, gaining an Expanded Duty Dental Assisting certification is a quick way to start taking on more responsibility and increase your value in the dental office.

There are some key differences you might enjoy after obtaining your Expanded Duty Dental Assistant certification (sometimes called Expanded Function Dental Assistant).

As you might expect, Expanded Duty Dental Assistants tend to perform more advanced tasks in the dental office than entry-level Dental Assistants. It can be exciting to learn valuable new skills and begin working with more independence. Dentists are often looking to hire qualified Dental Assistants—especially those with an EDDA certification.

Dental Assistant Responsibilities

Whether you have your expanded duty certification or not, your main undertaking is to assist the dentist with any and all tasks in the dental office. Dental Assistants might schedule appointments, prepare patients for treatments, sterilize equipment, process billing and payment, or process x-rays and lab samples. After obtaining an EDDA certification, you’ll likely begin to take on other duties:

At IBMC College, the EDDA certificate program is only five, 8-hour days over the course of 3 weekends. This schedule allows you the flexibility to be present at your job during the week and train on the weekends.

Dentists are often looking for ways to streamline the processes of their offices, so some are willing to pay for Dental Assistants to receive further certification that will qualify them to perform more tasks.

Asking your employer to consider covering the cost of the EDDA certification is an option, but paying out of pocket is an option, as well. The cost for the program is $1,500 in total (includes the final exam, books, and materials for the course), but IBMC College offers a payment plan if students are not able to pay in full at the time of enrollment.
