Overview
What Does a Dental Hygienist Do?
Dental hygienists work in dental offices, spending their day directly with patients performing clinical procedures. You'll split time between hands-on care — scaling teeth, applying fluoride, taking X-rays — and patient education about brushing techniques and oral health.
- Record and review patient medical histories.
- Feel and visually examine gums for sores and signs of disease.
- Examine gums using probes to locate recessed gums and signs of gum disease.
- Clean hardened deposits, buildup, and stains from teeth and beneath the gum line using dental instruments.
- Provide clinical services or health education to improve and maintain the oral health of patients or the general public.
- Chart conditions of decay and disease for diagnosis and treatment by the dentist.
- Expose and develop x-ray film.
- Attend continuing education courses to maintain or update your skills.

Requirements
Licensing & Certification
You must have a state license to work as a dental hygienist — this career is fully regulated, and no employer will hire unlicensed workers.
| Credential | Status | Cost | Renewal |
|---|---|---|---|
| Registered Dental Hygienist (RDH) State License | Required | $600 | 12-36 months |
Registered Dental Hygienist (RDH) State License (State Dental Board (national exam administered by Joint Commission on National Dental Examinations / ADA)) — Proves competency to clean teeth, examine patients for oral disease, and take X-rays. Required in all states
- Exam: Two-part process: (1) National Board Dental Hygiene Examination (NBDHE): 350 multiple-choice questions over 7.5 hours in two sessions — 200 discipline-based questions and 150 case-based questions. Passing score of 75 required. (2) State or regional clinical examination (ADEX, CDCA-WREB, CRDTS, or SRTA depending on state). Clinical exams test hands-on patient care skills including scaling, probing, and radiography.
- Cost: $600 (NBDHE exam fee, includes DENTPIN registration — non-refundable) + $400-$1,500 (state/regional clinical exam fee varies by testing agency and state) + $100-$400 (state licensure application fee)
- Renewal: Continuing education requirements vary by state, typically 20-36 hours per renewal cycle. Common required topics include infection control, CPR/BLS, and ethics. Renewal fees range from approximately $100-$300 depending on state. Examples: Texas requires 24 CE hours biennially; Illinois requires 36 CE hours every 3 years; New York requires 24 CE hours every 3 years.
All states require licensure, but clinical exam requirements vary — most accept the ADEX exam, while California requires its own state-specific test. Scope of practice differs significantly: some states allow you to work under general supervision, while others require a dentist on-site.
No interstate compact exists for dental hygienists. You will need a separate license in each state where you practice.

Will AI Replace Dental Hygienist?
AI can detect periodontal disease on X-rays and identify cavities in digital images, but all hands-on work remains human-only. Scaling tartar, root planing, and applying fluoride require manual dexterity and patient interaction that AI cannot replicate. Tools like Denti.AI help with diagnosis, but they assist rather than replace hygienists.
AI detects periodontal disease on X-rays; all scaling, root planing, and prophylaxis remain manual.
