An expanded functions dental assistant places and finishes fillings and does other restorative steps after the dentist prepares the tooth, as state rules allow. The dentist checks the work before the patient leaves. That frees the dentist to start on the next patient sooner.

You'll do the restorative and preventive work your state allows an expanded functions dental assistant to do, so our dentists can spend chair time on what only they can do. After the dentist prepares a tooth, you place and finish the restoration, and the dentist checks your work as your state requires. You also assist chairside and train other assistants.
2. Essential Duties and Responsibilities
Place, carve and finish amalgam and composite restorations after the dentist prepares the tooth, within your state's scope of practice for expanded functions assistants.
Place sealants, apply fluoride and do coronal polishing where your state allows.

What's different about expanded functions work in a dental group
The state creates this job and sets its limits. Its rule decides what the assistant may place, what the dentist must check, and who has to stay in the building.
One job, many state titles
DANB says each state defines expanded functions in its own way and gives the role its own title. You'll see EFDA, registered dental assistant in extended functions (RDAEF), licensed dental assistant and others. Before you move an EFDA to an office in another state, check whether their permit counts there. Source: Dental Assisting National Board: Become an EFDA.
The dentist has to stay in the building
Pennsylvania requires every expanded function to be done under direct supervision. That means the dentist is in the office, and personally diagnoses the problem and approves the procedure. The dentist stays while the assistant works, and checks the work before the patient leaves. If no dentist is on site, the EFDA does no restorations that day. Source: 49 Pa. Code § 33.205a: practice as an expanded function dental assistant.
What stays with the dentist
The same Pennsylvania rule lists what an EFDA may not do. That includes exams, diagnosis and treatment plans, and cutting tooth or gum tissue. It also rules out giving anesthesia or nitrous oxide, and the final check of how the work meets the bite. The EFDA's own list covers rubber dams, matrices and wedges, liners and bases, fillings, sealants, fluoride, polishing and some impressions. Source: 49 Pa. Code § 33.205a: practice as an expanded function dental assistant.
Two rooms, one dentist
The payoff comes from the schedule. The dentist numbs and prepares a tooth in one room, then moves on while the EFDA places and finishes the filling. That works only if the schedule books the EFDA's time as its own column, plus a few minutes for the dentist's check. Without that, an EFDA ends up working as a chairside assistant.
Notes show who did each step
Chart notes should say which steps the EFDA did and that the dentist checked the work before the patient left. That record shows the supervision rule was followed if the state board, a payer or a patient ever asks. Build it into the note template so nobody has to remember.
How much expanded functions dental assistants make
Dental assistants who work for dental offices earned a median of $23.08 an hour ($48,000 a year) in May 2025, according to the Bureau of Labor Statistics. That’s about the same as the $48,070 median for dental assistants in all industries. About 354,900 of the 387,790 dental assistants in that survey work for dental offices.
An hourly role. If the group pays EFDAs more than its other assistants, say how much more in the ad. It tells assistants whether earning the permit pays off.

Skills to hire for, and what you can teach
Hire for these
Places restorations that pass the dentist's check without rework
Sets rubber dams, matrices and wedges right the first time
Knows the state's expanded functions list and stops at its edge
Works on their own in one room while the dentist is in another
Teaches other assistants with patience
Teach these on the job
The group's restorative materials and each dentist's preferences
How your schedule template books EFDA time
Posterior composites, if their training leaned toward amalgam
Your intraoral scanner for final impressions, where your state allows
Note templates that record the dentist's check
Expect curing lights, composite and amalgam kits, rubber dam and matrix systems, magnifying loupes, and charting in the practice software. Name the composite system and matrix bands your offices use, because EFDAs trained on one system will ask.
Count these per EFDA and per dentist they work with. The restorative schedule the office books shapes them as much as anything the EFDA does alone.
Restorations approved by the dentist without rework
Of the restorations the EFDA placed, how many the dentist approved at the first check. Log any adjustment or redo in the procedure note so it can be counted.
Restorative appointments started on time
Restorative visits where the EFDA was ready to begin as soon as the dentist finished the prep. Use schedule time stamps or a simple start log.
Dentist wait time between procedures
Minutes the dentist waits for the EFDA, or for the EFDA's room, before the check. Sample a few days a month by hand if your software doesn't track it.
Procedure notes complete with dentist sign-off
Notes that list the steps the EFDA did and show the dentist's check, signed the same day. Pull unsigned notes from the software each week.
Career path

Practice managerMoves into running an office after years on the clinical side.
Through the state's own route. Pennsylvania accepts three: a board-approved EFDA program of at least 200 hours, a board-approved two-year dental assisting degree, or a hygiene school that taught at least 75 hours of restorative functions. Then candidates pass a written exam. The license renews every two years with 10 hours of continuing education. Two of those hours must cover child abuse recognition and reporting.
How much does an expanded functions dental assistant make?
Dental assistants who work for dental offices earned a median of $23.08 an hour ($48,000 a year) in May 2025, according to the Bureau of Labor Statistics. The middle half earned between $44,360 and $58,020 a year. Pay also depends on your local market, experience and overtime.
What is a CRFDA?
It stands for Certified Restorative Functions Dental Assistant. It's a national credential issued by the Dental Assisting National Board (DANB), made up of four exams: temporaries, impressions, restorative functions and sealants. The template asks for it as a plus, alongside the state permit. But it's the permit that lets the assistant do the work.
How is an EFDA different from a dental hygienist?
A hygienist holds a license to clean teeth and treat gum disease, and runs a schedule of their own patients. An EFDA works on the dentist's restorative patients, placing and finishing fillings after the dentist's prep. An EFDA who wants to treat patients on their own schedule would need hygiene school and a hygiene license.
Is an EFDA worth adding to a dental office?
It pays off when dentists have more filling and crown work than chair time. Look at each dentist's backlog of planned restorative work, and whether the office has a spare room for the EFDA. In an office whose days are mostly hygiene exams and checkups, a strong chairside assistant may help more.
What should an EFDA job ad include?
Your state's title for the role and the permit it takes. Then the procedures your dentists will hand off, and how many rooms the EFDA works across. Say whether the EFDA trains other assistants. Say whether the group pays for permit renewal and continuing education.
