What are the Dental Hygiene Boards?

To become a licensed Registered Dental Hygienist (RDH), you must pass the National Board Dental Hygiene Examination (NBDHE) โ€” a standardized written exam administered by the Joint Commission on National Dental Examinations (JCNDE) and required for licensure in all 50 U.S. states and Washington D.C.

The NBDHE consists of 350 multiple-choice questions: 200 discipline-based questions testing scientific knowledge, and 150 case-based questions that present real patient scenarios. A scaled score of 75 or higher is required to pass. The exam covers 8 core content areas: Anatomic Sciences, Physiology & Biochemistry, Microbiology & Immunology, Pathology, Pharmacology, Community Health, Clinical Dental Hygiene Sciences, and Patient Case Studies.

That's what Crack the Dental Hygiene Boards is built for.

Our 6 full-length NBDHE practice exam simulators mirror the real board format exactly โ€” same question types, same 8-hour timing, same difficulty distribution across all content areas. By exam day you will have already sat through six complete simulated boards. Your brain stops treating it as a threat and starts treating it as a routine.

Beyond practice exams: unlimited quiz generation, unlimited flashcard decks, 60+ hours of high-yield video lessons, and an AI Tutor available 24/7. Our Smart Study Scheduler takes your exam date and builds a complete day-by-day study plan around your life. You never wonder what to study again.

98% of our students pass the NBDHE on their first attempt. We have been helping dental hygiene students since 2005.

Let Us Be Honest

The fears holding you back? We have heard them all.

Here is what is probably going through your mind right now, and why it should not stop you.

"I am afraid I will not pass the NBDHE Exam, not graduate from dental hygiene school and not become a licensed and registered dental hygienist (RDH)"

We get it. Becoming a Registered Dental Hygienist (RDH) is challenging and difficult. But here is the truth: 98% of our students pass the NBDHE and become registered dental hygienist (RDH). Our Dental Hygiene Board practice exams mirror the real thing exactly. You will walk in knowing what to expect and score your highest.

"I am terrible at standardized tests"

That is exactly why we have 6 Full-Length NBDHE Tests. By exam day, you will have done it so many times it feels familiar. Plus, our AI creates a personalized study plan that fits YOUR schedule. Even 30 min/day works.

"What if I waste money on this?"

10,000+ dental hygiene students already passed their NBDHE using our platform. The real waste? Failing and paying $405 to retake. Delaying graduation. Postponing your RDH career and losing months of $80K+ salary. We have perfected NBDHE prep since 2005โ€”now supercharged with AI. Invest $300 now or risk losing $10,000+ later. Your choice.

Still unsure? Try our free diagnostic test first. See where you stand with zero commitment.

Questions?

Here are the ones we hear most often. Still have one? Contact us โ†’

Does "Crack the NBDHE" have a score guarantee?+
Yes. If you demonstrate that you have taken our exams with passing scores and still do not pass, we have you covered. As a testament to how much we care about your success on the National Board Dental Hygiene Examination (NBDHE), we provide all of our students with a pass guarantee. If you do not pass the real NBDHE, we will extend your access so you can keep preparing until you do. To qualify, you must demonstrate that you used Crack the NBDHE for at least one month, took ALL of our tests, and passed every test the FIRST TIME around in ACTUAL TESTING CONDITIONS mode. We will log into your account to confirm. Please note: our service only helps you determine whether you are ready for the NBDHE. It is NOT a panacea, and we do NOT claim that simply taking our tests means you will pass. We provide mock tests so you can simulate the real exam; passing them the first time is a strong indicator you will pass the actual exam, but if you did not pass our tests, that is a good indicator you simply were not ready. We give you everything you need to be maximally ready, but if you do not use our services to the maximum and/or take the full-length tests as intended, the guarantee will not apply. Contact us at hello@DentalHygieneBoards.com to start the guarantee process.
How is this different from a review book or a live seminar?+
Review books are passive โ€” you read, forget, and move on. Live seminars cost $1,000โ€“$2,000 and happen once. Our platform uses active recall, practice exams, AI-powered explanations, and adaptive quizzing โ€” the only methods proven to actually transfer knowledge into long-term memory. And you can study on your schedule, not ours.
I have tried other prep programs and failed. Why will this be different?+
Most programs give you content. We give you a system. Between 6 full-length mock exams, 5,000+ practice questions, an AI tutor that explains every wrong answer instantly, and a study schedule tailored to your exam date โ€” there is no guesswork. 98% of our students pass. The 2% who do not usually did not follow the schedule.
How long do I get access?+
Choose between 3-month or 6-month access. Access begins the moment your payment is processed โ€” no delays, no waiting. Extensions are available if you need more time.
Is there a free trial?+
Yes. You get 3 days of full access โ€” no credit card required. Explore the entire platform, try the AI tutor, do practice questions, watch videos. If you love it (you will), enroll. If not, you walk away with no charge.
Is this a subscription? Will I be charged again?+
Absolutely not. One-time payment. You will never be charged again. Access auto-expires after your chosen period โ€” no cancellation needed. No hidden fees. No surprises.
What devices does it work on?+
All of them. PC, Mac, iPhone, iPad, and Android. Study at your desk, on the bus, in bed, or in the library. Your progress syncs across every device.
How current is the content?+
All content reflects the current dental hygiene board blueprint. We update continuously as the blueprint evolves, and your access includes all future updates at no extra charge.
What if I do not pass?+
First โ€” 98% of students who use our platform pass on their first attempt. But if you need more time, we offer discounted extensions. Contact us and we will take care of you.
I am terrible at standardized tests. Will this actually help?+
That is exactly why we built 6 full-length mock exams. By the time you walk into the real thing, you will have done it so many times it feels familiar. Your brain stops seeing it as a threat and starts seeing it as a routine. That is the science of exam desensitization โ€” and it works.
Is this worth the money?+
The real question is: what does failing cost you? A retake fee of $405. Delayed graduation. Postponed licensure. Months of lost $70,000โ€“$90,000 RDH salary. Our platform is a fraction of that risk. Students who invest in proper preparation do not retake the exam.
