Complete Background Check and Health Screenings
Illinois requires a comprehensive background check including an FBI fingerprint check. Schedule your fingerprinting session through an approved provider such as Accurate Biometrics. You also need to complete health screenings, including a TB test and a drug screen. Results typically take 1-2 weeks. Disqualifying criminal records can lead to denial of licensure, but you may petition for a waiver.
Tip
Schedule your fingerprinting as soon as possible to avoid delays in processing times.
Research and Choose an Approved Training Program
Select a state-approved Dental Hygienist training program in Illinois. These programs must include 600 classroom hours and 1400 clinical hours. Visit the American Dental Association (ADA) website to find accredited programs. Attending a non-approved program will render you ineligible for the licensure examination. Ensure the program's accreditation status before enrollment.
Tip
Verify the accreditation of the program directly on the ADA website to ensure it is recognized by the Illinois state board.
Enroll in and Complete Training
Once you have selected an approved program, enroll and complete the required 2000 hours of training, comprising 600 classroom and 1400 clinical hours. These programs typically take 18 months to complete. Attendance and active participation are crucial for mastering the necessary skills and knowledge.

The exam fee is $400, and you must pass with a score of 75 or higher.
Tip
Schedule regular study sessions and take multiple practice exams to ensure readiness.
Register for and Schedule the NBDHE
After preparing for the NBDHE, register and schedule your exam through Pearson VUE, the testing vendor. You will need to choose a testing center and a date that fits your schedule. The exam takes approximately 8 hours to complete. Registration should be done well in advance to secure your preferred date and location.
Tip
Check for available dates at multiple testing centers to find the earliest suitable date.
Take and Pass the NBDHE
On the day of the exam, arrive at the testing center early with two forms of ID and your exam confirmation. The NBDHE consists of 350 questions to be completed in one day. If you fail, you can reschedule after 90 days. Passing the exam is crucial for moving forward in the licensure process.
Tip
Ensure you have all required documents a day before the exam to avoid last-minute issues.
Apply for Illinois State Certification
After passing the NBDHE, apply for your Dental Hygienist license through the IDFPR. Submit your application along with proof of education, exam results, and the application fee of $100. Processing typically takes 4-6 weeks. Once approved, your license will be issued and you will be added to the state registry.
Tip
Double-check your application for completeness to avoid delays in processing.
Receive Your Certification and Verify on State Registry

This verification is crucial as it confirms your legal ability to practice in Illinois. Keep your license document safe and maintain its validity through required continuing education and renewal processes.
