Dental Assistant Training - Expanded Duties/Coronal Polishing

Like many dentists, you may be looking for ways to increase your practice’s efficiency, production and revenue. Achieving those goals may be within reach when you enroll your assistants in the GDA Expanded Duties courses.
According to an ADA survey, dentists who employ assistants with Expanded Duties in their practices report being able to use their time more efficiently and see more patients per day. A dental assistant can perform a variety of routine duties in the dental office and the Expanded Duties program is designed to ensure dental assistants abide by the requirements set by the Georgia Board of Dentistry.


To be eligible to attend the GDA Expanded Duties Program the dental assistant must meet one of the following criteria:

1)    Possess current certification that the candidate is a Certified Dental Assistant.
2)    Be a graduate of a one (1) year accredited dental assisting program or a dental assisting program approved by the Board.
3)    Have been employed as a chair side assistant by a licensed dentist for a continuous six (6) month period within the previous three (3) years.  

In Addition, the candidate must have a high school diploma, or the equivalent thereof and proof of current CPR certification. Courses are offered on a FIRST COME, FIRST SERVED basis. Registration closes when a course reaches capacity OR one month (30 days prior) to course date – whichever comes first. (This is to allow the assistant to become familiar with the course study guides and gather all required clinical materials.)

If you have questions regarding expanded duties, please contact Sheila Watson.
