A dental hygienist is a licensed oral health professional who cleans teeth, screens for gum disease and oral cancer, takes x-rays, charts findings for the dentist, applies fluoride and sealants, and teaches patients how to keep their mouths healthy. In the US you cannot practice without graduating from a CODA-accredited program (usually a 2-year associate degree), passing the National Board Dental Hygiene Examination (NBDHE), passing a clinical exam, and getting a state license.

Stage 1 of 4 · about 16 weeks
Learn the basics of anatomy, tooth and head and neck structure, microbiology, infection control and oral health. Finish program prerequisites (anatomy and physiology, chemistry, microbiology, English, psychology) and research CODA-accredited programs and their admission requirements. Shadow a hygienist for a few hours to confirm the work suits you.
Dental and head and neck anatomy
Every probe stroke, x-ray and chart entry depends on knowing exactly where you are in the mouth. Hygiene programs start here, and strong anatomy grades help admission.
Microbiology and infection control
Your mouth work exposes you and patients to blood and saliva. Safe practice is legally required and is the first thing patients trust you with.
Oral health science and prevention basics
Hygienists teach prevention. If you understand why cavities and gum disease happen, you can later explain it clearly to patients and impress admissions interviewers.
Prerequisite science and general courses
Most CODA-accredited programs require specific courses with minimum grades, and admission is competitive, so strong grades are your ticket in.
Career research, program selection and shadowing
A two-year program is a big commitment. Shadowing and research make sure you choose it with open eyes and apply to the right schools.
