Expanded Functions Dental Assistant (EFDA) in Florida: Requirements and Duties Explained

What is an EFDA in Florida?

An Expanded Functions Dental Assistant is a dental assistant who has been formally trained to perform additional clinical procedures inside the patient's mouth — placing sealants, applying fluoride, polishing clinical crowns, placing and removing a rubber dam, fabricating a temporary crown, removing sutures, and similar reversible tasks — under the supervision of a licensed dentist.

Florida's statute calls this person an “expanded-duty dental assistant,” and the Board's rules speak of a dental assistant “who has received formal training.”^[1][2] “EFDA” is the profession's shorthand for the same thing. We use it here because it is what dentists put in job postings and what assistants type into a search bar, but when you read the rules, look for the words formal training.

Florida does not license dental assistants

This is the single most misunderstood point, so it is worth stating plainly: the Florida Board of Dentistry does not issue licenses to dental assistants.^[3] There is no state exam to sit, no registration number, and no renewal cycle for being a dental assistant or an EFDA.

What Florida regulates instead is the task. The Dental Practice Act lets a dentist delegate “remediable tasks” to a dental assistant, and then draws a line: a dental assistant may not perform an intraoral procedure except after such formal or on-the-job training as the Board prescribes by rule.^[1] The statute also authorizes the Board to set up a certification process for expanded-duty dental assistants; in practice, qualification today runs through training, and the document that proves it is your course certificate.

Three kinds of Florida dental assistant

Because nothing is licensed, the practical difference between assistants is what each one has been trained — and can prove they were trained — to do.

These are not rungs on one ladder. An assistant can be formally trained in expanded duties and still not be permitted to take radiographs, or the reverse. Most career assistants eventually hold both.

The legal framework in three pieces

1. Remediable tasks

Only remediable tasks can be delegated. The Board defines them as intraoral tasks that do not create unalterable changes in the oral cavity or contiguous structures, are reversible, and do not expose the patient to increased risk.^[4] Cutting tooth structure is irremediable. Polishing a crown is remediable. Diagnosis, treatment planning and prescribing are never delegable to anyone but another dentist.^[1]

2. Required training

Rule 64B5-16.002 defines the two kinds of training. On-the-job training is given by a licensed dentist who assumes full responsibility for making the assistant competent. Formal training is successful completion of an expanded-duty course or program either at a dental school or program accredited by the ADA's Commission on Dental Accreditation, or one approved by the Board for expanded-duties training.^[5]

The rule is specific about what a Board-approved course must contain: didactic and clinical training with stated objectives for each task, qualified faculty at no more than ten students per instructor, a detailed syllabus, an examination with a passing score of at least 75 percent, and a certificate showing the sponsor, course title, date, hours, participant name and the remediable tasks completed.^[5] That last item is why you should keep your certificate for the rest of your career.

3. Supervision

Every delegable task carries a supervision level. Under direct supervision the dentist examines the patient, diagnoses, authorizes the procedure, is on the premises during it, and approves the work before the patient leaves. Indirect supervision is the same without the final check. General supervision means the dentist has authorized the procedure but need not be present.^[4] For a full breakdown by task, see What can an EFDA do in Florida?.

What duties require formal training?

Rule 64B5-16.005 lists them. With formal training and direct supervision, the list includes placing or removing temporary restorations with non-mechanical hand instruments, polishing restorations and clinical crowns when not changing the contour of the tooth, removing excess cement, cementing temporary crowns and bridges, monitoring nitrous-oxide administration, fabricating temporary crowns or bridges intraorally, packing and removing retraction cord without vasoactive chemicals, and several orthodontic and impression tasks.^[2]

With formal training and indirect supervision, it includes impressions for study casts and opposing models, placing and removing periodontal and surgical dressings, rubber dams and matrices, applying cavity liners, varnishes or bases, applying topical fluorides, applying sealants, placing and removing orthodontic separators, securing or unsecuring an archwire, and removing sutures.^[2]

The Board revises this rule. It was most recently amended effective April 26, 2026, and further changes — including limited laser use — were noticed for development in September 2026.^[2] Treat any list you read, including this one, as a guide to the current text rather than a substitute for it.

How to become an EFDA in Florida

1. Work in a dental office. Expanded duties are delegated by a dentist to an assistant; there is no independent practice. Most courses, FIDA's included, expect you to be employed chairside already.
2. Choose an approved course. Either a CODA-accredited program or one on the Board of Dentistry's list of approved expanded duty programs.^[6] Confirm approval before you pay — here is how.
3. Complete the didactic and clinical components and pass the assessment at 75 percent or better.^[5]
4. Keep the certificate and give your employer a copy. It should list the specific tasks you were trained in. The office, not the state, holds the record.
5. Perform each task only at its supervision level. Formal training qualifies you; the dentist's delegation and presence authorize the act.

FIDA's Expanded Functions for the Dental Assistant course is 20 clock hours over five weeks — 13 hours of online theory and 7 clinical hours performed in your own office under your supervising dentist — across thirteen procedures, for $1,049. Our own enrollment requirements are that you are at least 18 and have three months of continuous chairside experience under a Florida-licensed dentist, confirmed by that dentist in writing. Those are FIDA's admission standards, set so that students arrive with the instrument familiarity the clinical component depends on.

Why assistants and dentists both want it

For the assistant, formal training is the difference between handing instruments and performing billable procedures — and between a job and a career with leverage. For the practice, every task a trained assistant performs is chair time returned to the dentist. A dentist who has been placing every rubber dam and fabricating every temporary personally is paying the most expensive hourly rate in the building to do it.

There is a compliance reason as well. Delegating professional responsibilities to a person not qualified by training, experience or licensure is a ground for discipline against the dentist.^[7] A certificate in the personnel file is the simplest protection there is.
