Understand what it means to be an Expanded Function Dental Assistant, and how to get there.

How to Become an Expanded Function Dental Assistant

Many dental assistants want to be able to perform expanded functions. Some states use the title Expanded Functions Dental Assistant (EFDA). Other states might use a title like Licensed Dental Assistant (LDA), Registered Dental Assistant (RDA), Registered Dental Assistants with Expanded Functions (RDAEF), or some other title. It can be hard to know what’s right for you!

What are expanded functions? Each state is a different, but some examples of expanded functions are applying sealants, taking impressions, performing coronal polishing, applying topical anesthetic or applying topical fluoride, to name a few.
