As of 2013, Iowa was home to 2,720 dental assistants, which represents a ratio of about 1.82 dental assistants for every one thousand residents. At $35,620, Iowa ranks high in terms of average annual salary for dental assistants when compared to the nation as a whole.
The Iowa Dental Board is the state agency that regulates the professional standards for all dental health occupations in the state, including dentists, dental hygienists, and dental assistants.
The Iowa Dental Board recognizes two types of dental assistant: Dental Assistant Trainees and Registered Dental Assistants. Both types of dental assistants must be registered in order to practice in the state.
Dental Assistant Trainees – A dental assistant trainee must be registered with the state of Iowa as holding dental assistant trainee status, and will practice on-the-job training underneath the direct supervision of a licensed dentist. Training may include basic dental assisting duties as well as radiography.
Registered Dental Assistants (RDA) – A registered dental assistant must be registered with the Iowa Dental Board as holding a certificate of registration. Registered Dental Assistants are able to perform extraoral services under the direct supervision of a licensed dentist.
Becoming a Dental Assistant in Iowa
Dental Assistant Trainee – An applicant must attain dental assistant trainee status according to the Iowa Dental Board before working as a dental assistant trainee in any office. To attain the status of dental assistant trainee, an applicant must submit an application for approval.
To submit a Dental Assistant Trainee Status Application, an applicant must meet the following requirements:

Once attained, dental assistant trainee status is valid for one (1) year. If the dental assistant trainee status has lapsed, the trainee must meet requirements for registration and attain a certification of registration to continue practicing as a dental assistant.
Registered Dental Assistant (RDA) – To become a registered dental assistant, a dental assistant trainee must be eligible for registration and go through the application process.
To attain eligibility for registration, an applicant must be at least 17 years old and qualify in one of the following ways:
- Work in a dental office as a dental assistant trainee for at least six (6) months

The Iowa Dental Board recognizes approved testing sites for the Jurisprudence exam.
A registered dental assistant will have one of three types of registration on the certificate of registration:
- Registered Dental Assistant (RDA)
- Qualified/Registered Dental Assistant (QDA)
- Qualified/Non-registered Dental Assistant (XDA)
Expanded Function Training for RDAs – A registered dental assistant may pursue expanded function training, which will give the assistant the ability to perform whichever expanded functions the assistant has been trained and tested in under the direct supervision of a licensed dentist.
Expanded Functions include but are not limited to the following:

Training must be ADA-accredited, as well as approved by the Iowa Board. Training may be administered through an accredited and approved dental assisting program, or through on-the-job training from a licensed dentist, as long as the training meets the Board’s standards of approval. To ensure the training meets the criteria of the Board, documentation of training must be maintained and held as proof.
The Iowa Dental Board provides An Expanded Functions Course Resource List for further details on course requirements and availability.
To be qualified to pursue expanded function training, a registered dental assistant must:
- Hold current Dental Assisting National Board (DANB) certification

- Have a minimum of two (2) years experience as dental assistant in a state that does not require registration
National Certification and Associations
Dental Assisting National Board Certification – The Dental Assisting National Board (DANB) offers national certification exams and issues national certifications for dental assistants. DANB certification is one option to become eligible for expanded function training.
There are four options for national certification:
- Certified Dental Assistant (CDA)
- Certified Orthodontic Assistant (COA)
- Certified Preventive Functions Dental Assistant (CPFDA)
- Certified Restorative Functions Dental Assistant (CRFDA)
Each of the exams is made up of component exams, which may be taken stand-alone or as part of the full exam.
Exams are given at Pearson VUE centers. The testing centers in Iowa are located in the following cities:
- Des Moines, IA
- Coralville, IA
- Davenport, IA
There are also testing centers located in the following cities, close to the boarder of Iowa:
- Rochester, MN
- Omaha, NE
Certification alone does not authorize a dental assistant to engage in the dental assisting practice in Iowa. Only official registration in the state allows an assistant to practice.
American Dental Assistants Association (ADAA) – The American Dental Assistants Association has component state associations, and a dental assistant in the state of Iowa may join the Iowa Dental Assistants Association chapter. Joining the state chapter will give a dental assistant access to the following:
- Continuing Education Resources
- Networking Opportunities
- Annual Sessions
- Events and Resources
Though not necessary for registration, joining the Iowa Dental Assistants Association, which is dedicated to the advancement of the dental assisting profession, will give a dental assistant extra support and resources for education, credentialing, and professional actives.
Registration Renewal and Continuing Education
