What does an EFDA do?

EFDAs can perform all the duties of a dental assistant — and more. Each state defines expanded functions differently. Although each state is different, some common examples of expanded functions are applying sealants, taking impressions, performing coronal polishing, applying topical anesthetic or applying topical fluoride, to name a few. EFDAs must be skilled multitaskers because they are responsible for so many duties. Because of their advanced standing, EFDAs often earn higher salaries.

What education or training is needed?

EFDAs typically have a few years of experience and may have taken additional coursework or passed additional exams. If you’re interested in becoming an EFDA, it’s a good idea to start out as a dental assistant to learn the basics and get a sense of what the day-to-day pace of working in a dental office is like. After you’ve gained some experience and know that you’re ready for the next step, you’ll want to look up what the EFDA pathway is in your state. If your state approves EFDA courses or programs, you can look up a program near you.
