How to Become a Dental Hygienist (Step-by-Step Guide)

What Does a Dental Hygienist Actually Do?

Most people think of dental hygienists as "the person who cleans your teeth." That's part of it, but the job is more clinical than that description suggests. On a typical day, a dental hygienist reviews a patient's medical and dental history, takes X-rays, removes plaque and tartar buildup, checks for signs of gum disease and oral cancer, and documents findings for the dentist to review.

Hygienists also spend a significant amount of time on patient education — explaining how to brush and floss correctly, discussing the link between oral health and systemic conditions like diabetes or heart disease, and advising patients on diet and tobacco use. In many states, hygienists can administer local anesthesia, place sealants, and apply fluoride treatments independently.

The work environment is usually a private dental office, though hygienists also work in schools, public health clinics, hospitals, and corporate dental chains. Most positions are full-time, and part-time schedules are common — which is one reason the career appeals to people with families or other commitments.

Step-by-Step: How to Become a Dental Hygienist

Step 1: Finish High School With the Right Foundation

You don't need a specialized high school diploma, but the courses you take matter. Dental hygiene programs are competitive, and your application will be stronger if you've taken biology, chemistry, anatomy, and math. Some programs also look at your GPA in science courses specifically, not just your overall average.

If you're already out of high school and your science background is thin, community college prerequisite courses are a common and accepted way to fill the gap. Many applicants take a semester or two of coursework before applying to accredited programs — it's a normal part of the process.

Step 2: Choose an Accredited Dental Hygiene Program

This step matters more than most people realize. Your program must be accredited by the Commission on Dental Accreditation (CODA) — the accrediting body recognized by the American Dental Association. If you graduate from a non-accredited program, you won't be eligible to sit for the national board exam or get licensed. There's no workaround.

CODA-accredited programs come in two main formats:

• Associate Degree (ADH): The most common path. Typically takes 2–3 years and is offered at community colleges and some universities. Qualifies you for licensure and most entry-level positions.
• Bachelor of Science in Dental Hygiene (BSDH): Takes 4 years (or 2 additional years if you already have an associate degree). Opens doors to supervisory roles, research, education, and some public health positions — and can lead to higher pay over time.

You can search for CODA-accredited programs on the ADA's website. Look at acceptance rates, clinical hours offered, and whether the program has strong connections to local dental offices for externships.

Step 3: Complete Your Degree

Dental hygiene programs are demanding. You'll spend the first half in classroom and lab settings, covering subjects like periodontology, oral pathology, radiology, pharmacology, head and neck anatomy, and dental materials. The second half shifts to clinical rotations, where you work directly with patients under faculty supervision.

Those clinical hours are important — not just for your education, but because licensing boards require documentation of a minimum number of patient care hours. Most programs integrate enough hours to meet state requirements, but it's worth confirming before you enroll, especially if you're considering practicing in a state with stricter standards.

Programs are usually full-time and structured, so working more than part-time during your enrollment can be difficult. Plan your finances accordingly before you start.

Step 4: Pass the National Board Dental Hygiene Examination (NBDHE)

After graduating, you need to pass the National Board Dental Hygiene Examination, administered by the Joint Commission on National Dental Examinations (JCNDE). The exam tests your knowledge across the full scope of dental hygiene practice — covering basic sciences, dental hygiene sciences, and case-based scenarios.

The NBDHE is computer-based and offered at Pearson VUE testing centers across the country. Most graduates sit for it shortly after finishing their program, while the material is still fresh. Pass rates among first-time test takers have historically been strong — typically above 85% — but it requires focused preparation. Your program should provide study resources, and many graduates use dedicated board prep materials as well.

Step 5: Pass Your State Clinical Exam and Get Licensed

In addition to the national board exam, every state requires a clinical examination — a hands-on assessment where you demonstrate patient care skills on a real patient. The specific exam varies by state; most states accept results from one of a few regional testing agencies, but requirements differ.

Once you've passed both exams, you apply for licensure through your state's dental board. You'll submit proof of graduation, exam scores, and typically pay a licensing fee. Some states also have jurisprudence requirements — a short exam on state dental laws — before they issue your license.

Licenses need to be renewed periodically (usually every 1–2 years), and most states require continuing education credits as a condition of renewal. It's a manageable requirement once you're working — most employers and professional associations make CE accessible.

Step 6: Apply for Jobs and Start Your Career

With your license in hand, you're ready to apply. Most new graduates find positions in private dental offices, which tend to be the most accessible entry point. Job boards, dental staffing agencies, and your program's alumni network are all useful resources. The market for licensed hygienists is consistently strong in most regions of the country.

Starting pay varies by location, experience, and practice setting. If you want a realistic picture of what to expect in your first year, our Entry Level Dental Hygienist Salary page breaks down starting wages by state and employment type. Knowing the numbers ahead of time helps you evaluate job offers with confidence.

How Long Does It Take to Become a Dental Hygienist?

The total timeline depends on your educational path and how quickly you move through each stage. Here's a realistic overview:

For most people, the associate degree path takes about two to three years of post-secondary education, plus a few months for licensing. That's a relatively short runway for a career that pays nearly $90,000 at the median.

How Much Do Dental Hygienists Make?

The BLS reported a median annual salary of $94,260 for dental hygienists in 2024 — which translates to roughly $45.32 per hour. The top 10% of earners made over $119,000. Those aren't outliers working unusual jobs; they're typically experienced hygienists in high-demand markets or states where cost of living and competition for staff have pushed wages up.

Where you work geographically makes a real difference. Our Dental Hygienist Salary by State page shows how much median pay varies between states — in some high-paying states, the median is well above $100,000, while others sit closer to $70,000. If you have flexibility about where you live, that data is worth reviewing before you start your job search.

For hygienists curious about which locations pay the most nationally, the Highest Paying States for Dental Hygienists page gives you a ranked breakdown with median wages. It's a useful reference whether you're planning a move or just benchmarking your current offers.

Tips to Maximize Your Earning Potential

A dental hygiene license gets you in the door. What you do after that shapes your long-term trajectory. A few things that make a real difference:

• Know what your time is worth by the hour. Many hygienists work part-time or pick up per diem shifts, which makes understanding your effective hourly rate essential. Our Dental Hygienist Hourly Pay breakdown shows what hygienists earn by hour across different states and experience levels — useful context for negotiating temp or per diem rates.
• Consider your geography strategically. Some states pay significantly more than others, and moving even one state over can mean a $15,000–$25,000 increase in median salary. If you're early in your career and have flexibility, it's worth factoring into your decisions. Use our Compare Dental Hygienist Salaries Between Cities tool to run those comparisons side by side.
• Add credentials that expand your scope. Local anesthesia certification, laser certification, and training in periodontal therapy can make you more valuable to practices that want a hygienist who can do more. Some of these are available as continuing education and don't require going back for another degree.
• Don't overlook practice setting. Corporate dental groups and specialty practices sometimes pay more than general private offices. Academic institutions, public health agencies, and the military are also worth looking into — compensation structures differ meaningfully from private practice.
• Negotiate from the start. Entry-level hygienists often accept the first offer without pushing back. Knowing the market rate for your area before you walk into that conversation gives you real leverage. Starting $3–5/hour higher than you might otherwise accept adds up to tens of thousands of dollars over a decade of work.

If you've made it through this guide and dental hygiene still sounds like the right fit, the next step is practical: look up CODA-accredited programs in your area, check their admission requirements, and start mapping out your timeline. The career path is clear and the job market is strong — most of what stands between you and a licensed position is a decision and a few years of focused work.
