Do You Need a Certificate to Work as a Dental Assistant?
It depends on your state and what you want to do on the job. The straight answer is that most states, including Illinois and Indiana, do not require a certificate just to get hired as a dental assistant. But there's an important line between getting hired and being able to perform certain procedures, and that's where certification becomes necessary.
Here's how it actually breaks down.
No Universal Requirement Across the U.S.
Unlike nursing or dental hygiene, dental assisting does not have a single national licensing requirement. Each state sets its own rules, which means the answer to this question is different depending on where you live and work.
Some states require certification before you can work as a dental assistant at all. Others allow you to work with no formal training and learn everything on the job. Most states, including Illinois and Indiana, fall somewhere in the middle.
What Illinois Actually Requires
In Illinois, you can legally be hired and work as a dental assistant without a certificate. General chairside duties like passing instruments, suctioning, taking impressions, charting, and patient prep do not require a formal credential.
Where certification becomes required is when you move into what Illinois calls expanded functions. These are procedures where the dental assistant is directly performing a clinical task on a patient. In Illinois, expanded functions include:
Coronal polishing
Pit and fissure sealants
Restorative functions (placing and finishing restorations)
To perform any of these legally, you need a course that is approved by the IDFPR (Illinois Department of Financial and Professional Regulation). And for coronal polishing and sealants specifically, you also need to have accumulated at least 1,000 hours of clinical dental assisting experience before you can even enroll in those courses.
So the path in Illinois looks like this: get hired, gain experience, then get certified for expanded functions as you build your hours.
What Indiana Actually Requires
Indiana follows a similar structure. There is no state requirement to hold a certificate to work as a general dental assistant. You can be hired and trained on the job for basic chairside duties.
For expanded functions in Indiana, including coronal polishing and fluoride application, a state-approved certification is required. As in Illinois, performing these procedures without the proper credential is a legal issue for both the assistant and the supervising dentist.
Why the Certificate Still Matters Even If It's Not Required
Just because you don't legally need a certificate to get hired doesn't mean it won't affect your career. A few things worth knowing:
Hiring preference. Most dental offices prefer to hire candidates who have completed some form of training, even for entry-level positions. A certificate shows you're serious and reduces the time it takes to get you productive.
Pay difference. Certified dental assistants who can perform expanded functions are more valuable to a practice and typically earn more. An office that has an assistant who can perform coronal polishing or sealants doesn't need to schedule those tasks through the hygienist, which saves the practice time and money.
Career ceiling. If you stay uncertified, there's a limit to what you'll be allowed to do. At some point, if you want to grow in this career and take on more responsibility, the certification will become necessary anyway.
Job security. Assistants who can do more are harder to replace. Having expanded functions certifications makes you a more essential part of the team.
How to Get Started the Right Way
If you're coming in with no background at all, the most straightforward path is to complete a full dental assistant training program first. That gets you job-ready before you even apply, which makes the hiring process a lot easier.
At Dental AssistEd, the 8-Week Become a Dental Assistant Program is designed for people starting from zero. In 8 weeks you'll get the hands-on training you need to work confidently in a dental office and begin building your clinical hours toward future certifications.
Illinois residents may qualify for a WIOA grant and pay $0 in tuition. The Workforce Innovation and Opportunity Act is a state-funded program that covers training costs for people entering in-demand careers. Dental assisting qualifies, and we help students navigate the grant process. If cost has been the reason you haven't started yet, this is worth looking into.

Once you're working and have your 1,000 clinical hours, you can come back to get certified for expanded functions. At that point, we offer IDFPR-approved courses including:
EFDA Restorative Course (the highest level of expanded functions in Illinois)
The Bottom Line
You do not need a certificate to get hired as a dental assistant in Illinois or Indiana. But you will need one to perform expanded procedures, and having formal training before you apply puts you ahead of most candidates who don't.
