Dental Assistant Requirements in Florida: Registration, X-Ray Rules & Allowed Duties
Florida does not require a dental assistant to register or hold a general license to work under a dentist's supervision.
Chapter 64B5-16, F.A.C. instead delegates specific 'remediable tasks' by the training an assistant has completed and the supervision level required — direct, indirect, or general.
Positioning and exposing x-rays requires certification as a dental radiographer or graduation from a Board-approved dental assisting program.
Monitoring nitrous oxide during administration is delegable with formal training under direct supervision.
The rules print no separate prohibited-duties list or continuing-education requirement for assistants.

The Short Version
- Registration or licensure
- Chapter 64B5-16, F.A.C. sets no general registration or licensing requirement for the basic dental-assisting role; the only credentials the rules define for an assistant are the dental radiographer certification and the formal-training certificate required for specific remediable (expanded-function) tasks.
- Taking x-rays
- A dental assistant may position and expose dental radiographic images only if certified by the Department as a dental radiographer, or if they graduated from a Board-approved dental assisting school or program; certification requires at least three months of on-the-job training under a Florida-licensed dentist's direct supervision plus a Board-approved course completed within 12 months.
What direct, indirect and general supervision mean here
The rule defines three supervision levels for delegated remediable tasks.
Direct supervision requires the dentist to examine the patient, diagnose, authorize the procedure, stay on the premises while it is performed, and approve the finished work before the patient leaves.
Indirect supervision drops the requirement to approve the finished work but still requires the dentist on the premises during the procedure.
General supervision only requires the dentist to have examined, diagnosed, and authorized the procedure in advance; an authorization for general supervision is valid for a maximum of 13 months.
Direct supervision requires that a licensed dentist examine the patient, diagnose a condition to be treated, authorize the procedure to be performed, be on the premises while the procedure is performed, and approve the work performed prior to the patient's departure from the premises.
Remediable tasks a dental assistant may perform
Florida delegates a defined list of reversible, low-risk 'remediable tasks' to a dental assistant, split by training completed and supervision level required.
With formal training and direct supervision, an assistant may perform an 18-item list, among them placing or removing temporary restorations, polishing restorations and crowns, cementing temporary crowns, and monitoring nitrous oxide during administration.
With formal training and indirect supervision, an assistant may perform a 13-item list, among them placing or removing rubber dams and matrices, applying cavity liners and sealants, and positioning and exposing radiographic film and sensors.
With only on-the-job training, an assistant may perform a shorter list — such as applying topical anesthetics, retracting tissue, and taking vital signs — under direct, indirect, or general supervision.
The use of a laser is never a remediable task.
Remediable tasks, also referred to as expanded functions of dental assistants, are those intra-oral tasks which do not create unalterable changes in the oral cavity or contiguous structures, are reversible and do not expose a patient to increased risks. The use of a laser or laser device of any type is not a remediable task.
Positioning and exposing x-rays
A dental assistant may position and expose dental radiographic images only if certified by the Department as a dental radiographer, or if they graduated from a Board-approved dental assisting school or program.
An assistant who has not graduated from such a program can become a certified dental radiographer by applying to the Department, completing at least three months of continuous on-the-job training in positioning and exposing images under a Florida-licensed dentist's direct supervision, and completing a Board-approved course — covering topics such as radiography practice and equipment, radiation safety, hands-on sensor positioning, radiographic anatomy, and infection control — within 12 months of finishing the on-the-job training.
The certification must be displayed to the public where the assistant works.
Dental assistants may position and expose dental radiographic images only if they have been certified by the Department as dental radiographers or have graduated from a Board-approved dental assisting school or program.
Nitrous oxide monitoring
The only sedation-related task the rule delegates to a dental assistant is monitoring the administration of nitrous-oxide oxygen.
An assistant who has received formal training and works under direct supervision may make adjustments only during the administration and must turn the gas off at the completion of the procedure.
The rule does not delegate starting the flow of nitrous oxide, or any other sedation or anesthesia task, to a dental assistant.
Monitor the administration of the nitrous-oxide oxygen making adjustments only during this administration and turning it off at the completion of the dental procedure;
Formal training, on-the-job training, and displaying the certificate
Remediable tasks that require 'formal training' call for completing an expanded-duty course that is either part of an accredited dental school's regular curriculum or separately approved by the Board, with standards for curriculum content, faculty experience, a detailed syllabus, and a passing score of at least 75% on a clinical or written exam, after which the assistant receives a certificate listing the tasks covered.
Tasks that require only 'on-the-job training' are taught directly by the supervising dentist, who takes full responsibility for confirming the assistant is competent before delegating the task.
Whichever certificate an assistant holds, the supervising dentist must display it in a conspicuous public place where the assistant performs the tasks and keep a copy on file in the office.
The supervising licensee is responsible for ensuring that any dental assistant or dental hygienist who performs remediable tasks as a result of formal training shall display the certificate received at the conclusion of the training in a conspicuous public place where the tasks are performed.
Performing remediable tasks in an emergency
If the dentist of record cannot be physically present to pre-examine a patient, and the patient will be seen by a dentist within three days, a CPR-certified dental assistant who has been trained under Rule 64B5-16.002 may perform a short list of remediable tasks without the usual pre-examination — for example, re-cementing a loose orthodontic band, replacing a lost periodontal dressing, or cementing a lost temporary crown or bridge, when the patient is uncomfortable from the loss.
This emergency allowance is limited to the specific tasks the rule lists.
In an emergency in which a dentist of record is unable to be physically present to pre-examine the patient, and the patient will be seen by a dentist within 3 days, the following remediable tasks may be performed by both dental assistants and dental hygienists who hold current CPR certification from the American Red Cross, the American Heart Association or an equivalent CPR training agency and who are trained pursuant to Rule 64B5-16.002, F.A.C., without pre-examination by a dentist:
Frequently Asked Questions
Do I need to register or get a license to work as a dental assistant in Florida?
Chapter 64B5-16, F.A.C. does not set up a general registration or licensing requirement for the basic dental-assisting role — there is no title, license, or registration named to begin working under a dentist's supervision.
The only credentials the rules define are a dental radiographer certification, needed to expose x-rays, and formal-training certificates for specific remediable (expanded-function) tasks.
Confirm current requirements with the Florida Board of Dentistry.
Can a dental assistant take x-rays in Florida?
Only if certified.
Rule 64B5-9.011 says an assistant may position and expose dental radiographic images if they graduated from a Board-approved dental assisting program, or if they became a certified dental radiographer through the Department, which requires at least three months of on-the-job training under a Florida-licensed dentist's direct supervision plus a Board-approved radiography course completed within 12 months.
The certification must be displayed where the assistant works.
Verify current course approval with the Florida Board of Dentistry.
Does the dentist have to be in the room while a dental assistant works?
It depends on the supervision level the task requires.
Under Rule 64B5-16.001, direct supervision means the dentist is on the premises during the procedure and approves the finished work before the patient leaves; indirect supervision only requires the dentist on the premises during the procedure; general supervision requires the dentist to have examined and authorized the procedure in advance but not be present while it is performed.
Ask the Florida Board of Dentistry which level applies to a given task.
What tasks can a Florida dental assistant never perform?
The source rules reviewed for this page — Chapter 64B5-16 on remediable tasks and Rule 64B5-9.011 on radiography — list what a dental assistant may perform and do not print a separate list of prohibited tasks.
Anything not named as a remediable task in Rule 64B5-16.005, or otherwise authorized, falls outside what the rule delegates to an assistant.
Confirm the current scope of practice with the Florida Board of Dentistry before delegating an unlisted task.
How does a dental assistant become qualified to perform expanded-function tasks in Florida?
Rule 64B5-16.002 sets two paths.
Formal training means completing an expanded-duty course that is either part of an accredited dental program or separately approved by the Board, including a detailed syllabus, qualified faculty, and a passing score of at least 75% on a clinical or written exam.
On-the-job training means the supervising dentist personally trains the assistant in the task and takes responsibility for confirming competency.
Which path applies depends on the specific task listed in Rule 64B5-16.005.
