To become a dental hygienist in the US, you complete an accredited dental hygiene program, usually an associate's degree that BLS says typically takes 3 years, then pass written and clinical examinations and get licensed in your state. Every state requires dental hygienists to be licensed, and many jobs also ask for CPR certification.
That 3-year figure is the bit people don't expect. It's an associate's degree, but the programs include prerequisites, lab work and clinical training, so it isn't the two years most associate's degrees take.
This is a careers guide: the steps, pay and outlook below all come from the US Bureau of Labor Statistics (BLS) Occupational Outlook Handbook, read in October 2026.
Dental hygienists in numbers
| Measure | BLS figure |
|---|---|
| Median pay (May 2025) | $98,100 a year, $47.16 an hour |
| Lowest 10% and highest 10% | Under $74,880 and over $126,050 |
| Typical entry-level education | Associate's degree |
| Jobs in 2025 | 225,300 |
| Projected growth 2025 to 2035 | 8%, much faster than average |
| Openings each year | About 15,000 on average |
| Work in dentists' offices | 94% |
Those pay figures are as of October 2026. It's one of the highest-paying careers you can enter with an associate's degree.
How to become a dental hygienist, step by step
- Take biology, chemistry and math in high school. BLS recommends them for anyone interested in the field.
- Complete the prerequisites. Most dental hygiene programs require them, often including college-level courses, and requirements vary by school.
- Enrol in an accredited dental hygiene program at a community college, technical school or university. Expect laboratory, clinical and classroom instruction in subjects such as anatomy, medical ethics and periodontics.
- Graduate. Most hygienists hold an associate's degree; a bachelor's or master's is usually required for research, teaching or public and school health programs.
- Pass the written and clinical examinations your state requires.
- Get your state licence from your state's Board of Dental Examiners, and get CPR certified if your employer asks for it.
- Keep your licence active with the continuing education your state requires.
The insight: part time is normal
Here's what the salary figure hides. BLS says many dental hygienists work part time, and some work for more than one dentist because a practice may only need a hygienist a few days a week. That can be a perk if you want flexibility, but if you need a full-time wage, ask about hours before you accept an offer. Benefits such as vacation, sick leave and retirement contributions may only be available to full-time staff.
Your scope of work also depends on where you live. BLS notes that, depending on the state and the treatment, dental hygienists may work without the direct supervision of a dentist. So the job looks different in different states, not just the licence.
Where dental hygienists work
| Employer | Share of jobs (2025) | Median pay (May 2025) |
|---|---|---|
| Offices of dentists | 94% | $98,280 |
| Offices of physicians | 1 in every 100 | $91,160 |
| Government | 1 in every 100 | $80,830 |
Hygienists wear safety glasses, surgical masks and gloves, and follow procedures to protect themselves and patients when taking x rays. If you're looking at practices to apply to, a modern office often runs on dental practice management software, and some are adding AI tools for dentists to cut no-shows, which is worth asking about at interview.
Choosing a program
Accreditation is the first filter. BLS says most states require a degree from an accredited dental hygiene program before you can sit the licensing exams, so a cheaper program that isn't accredited can leave you unable to get licensed. Check three things before you apply: that the program is accredited, which prerequisites it wants (these vary by school and often include college-level science), and how much clinical time it includes, since the clinical exam is part of licensure in most states.
Licensing is handled state by state through your state's Board of Dental Examiners, and BLS points to CareerOneStop for a list of state licensing board requirements. Look up the board in the state where you plan to work before you pick a school, because that's the rulebook your exams and continuing education will follow.
If you think you'll want to teach or work in public or school health programs later, look at programs that let you continue to a bachelor's degree. BLS says a bachelor's or master's is usually required for those roles, while master's programs in dental hygiene are relatively uncommon.
Skills that matter
- Dexterity: you work in tight spaces with precise instruments.
- Communication: you explain oral health and care plans to patients and the dentist.
- Interpersonal skills: BLS stresses patience with patients who are anxious about treatment.
- Attention to detail: you follow strict rules and protocols.
When you write your CV, list your licence and clinical hours first, then certifications. Here's how to show CPR certification on a resume so a busy practice manager spots it.

My verdict
Becoming a dental hygienist is a strong choice if you want healthcare work with high pay and no medical school. Budget about 3 years for the program, check your state's licensing rules early, and be clear with employers about the hours you want, because part-time roles are common. With 8% growth projected and about 15,000 openings a year, the demand is steady.
