How to become a dental hygienist: steps, timeline, and pay

If you want a licensed, well-paid clinical career without a four-year-plus commitment, dental hygiene is one of the strongest options available. The path is well-defined and gated by licensure, so the steps below are less a suggestion than a checklist. Here's how it actually works — and what the credential is worth at the end.

Step 1: Complete the prerequisites

Most hygiene programs expect college-level prerequisites — commonly anatomy and physiology, chemistry, microbiology, and English or psychology — before you apply. Programs are competitive and often have waitlists, so strong grades in these courses matter. Knock them out at a community college if you're starting fresh.

Step 2: Graduate from a CODA-accredited program

The core credential is an associate degree in dental hygiene from a program accredited by the Commission on Dental Accreditation (CODA). This typically takes about two to three years of full-time study combining classroom science, clinical technique, and supervised patient care. Accreditation isn't optional bureaucracy — it's what makes you eligible for the licensing exams, so confirm a program's CODA status before you enroll. Bachelor's-level programs exist too and take longer, but aren't required to practice chairside.

Step 3: Pass the board exams

Licensure requires passing exams that test knowledge and clinical skill: a national written board exam plus a clinical/practical exam (administered through regional testing agencies). Requirements can vary by state, so check your state dental board for the exact exams it accepts.

Step 4: Get licensed in your state

With your degree and passing scores, you apply for a license from the state where you'll work. Because licensing is state-by-state, a license doesn't automatically transfer if you move — some states have reciprocity or endorsement paths, others require additional steps. This is worth researching early if you expect to relocate; it's a major theme in why the same dental job pays differently by state.

What it pays

The reason this path is so popular: the pay is strong for the education required. The national median is about $47.16/hr an hour — roughly $98,100 a year at full-time hours (BLS OEWS May 2025) — with the full percentile range on the hygienist salary page. Note that most hygienist pay is hourly, so your annual income depends on scheduled hours, and it varies a lot by state and metro.

Before you commit

Go in with the full picture, not just the salary. Read is dental hygiene a good career? for the honest trade-offs — the physical demands and the relatively flat pay ceiling — and, if you want a higher long-term ceiling and will invest far more time, compare the dentist vs. hygienist paths first.
