What does a dental hygienist do?
Dental hygienists focus on preventing and catching problems in the mouth before they get serious. They see many patients each day, usually for cleanings and checkups, and they work closely with dentists.
A typical appointment starts with reviewing the patient’s health history and checking blood pressure. The hygienist then examines the teeth and gums, measures gum pockets to check for gum disease, and removes plaque and tartar with hand and ultrasonic instruments. They polish teeth, take X-rays, and may apply fluoride or sealants.
Teaching is a big part of the job. Hygienists show patients how to brush and floss, explain how diet and habits affect their teeth, and talk through treatment the dentist recommends. They also record findings so the dentist can make a diagnosis.
In some states, hygienists can give local anesthesia, place certain fillings or work with more independence in settings like nursing homes and schools.
Good hygienists have steady hands, sharp eyesight and a gentle touch. Many patients are nervous about dental visits, so a calm, friendly manner goes a long way.
Tools of the job include scalers, curettes, ultrasonic cleaners, periodontal probes, X-ray equipment, intraoral cameras and practice software.
Dental hygienists work in:
- General dental offices
- Periodontal and pediatric practices
- Community and public health clinics
- Schools and nursing homes
- Dental hygiene schools, as educators
A typical day
- Review the patient schedule and set up your operatory
- Update health histories and take blood pressure
- Clean teeth, chart gum health and take X-rays
- Teach patients about home care
- Go over findings with the dentist during the exam
Dental hygienist pay and job outlook
According to the U.S. Bureau of Labor Statistics, dental hygienists earn a median of $98,100 a year, or $47.16 an hour. That is one of the highest medians for jobs that need only an associate degree.
The BLS counts about 225,300 dental hygienist jobs. Employment is projected to grow 8% from 2025 to 2035, with about 15,000 openings each year.
Pros
- High pay for a two-year degree.
- Flexible schedules, including part-time work.
- Regular daytime hours in most offices.
- You build long-term relationships with patients.
Cons
- Programs are competitive, and prerequisites add time.
- Repetitive motions can cause hand, wrist, neck and back pain.
- Part-time jobs may not offer full benefits.
- Room to advance inside a dental office is limited without more education.
Training options: an accredited degree is required
There is no apprenticeship or on-the-job route to becoming a dental hygienist. Every state requires graduation from a CODA-accredited dental hygiene program.
Associate degree. This is the most common path. Most programs take about two years after prerequisites. They are offered mainly by community colleges and technical colleges, and they include a lot of supervised clinic time treating real patients.
Bachelor’s degree. Four-year programs add courses in research, public health and education. A bachelor’s degree can help if you want to teach, work in public health or go on to a master’s degree. Degree completion programs let associate-degree hygienists finish a bachelor’s while working.
Costs vary widely, from about $10,000 at some public community colleges to $50,000 or more at private schools, not counting prerequisites. Check what is included, since instrument kits can be expensive.
Certification and licensing by state
Every state requires dental hygienists to be licensed. The usual steps are:
- Graduate from a CODA-accredited program.
- Pass the National Board Dental Hygiene Examination (NBDHE), a written exam from the Joint Commission on National Dental Examinations.
- Pass a clinical exam accepted by your state. Many states accept regional exams, such as the ADEX exam given by CDCA-WREB-CITA or the CRDTS exam.
- Pass a state law and ethics (jurisprudence) exam, if your state requires one.
Scope of practice varies by state. Some states allow hygienists to give local anesthesia or nitrous oxide with a permit, place certain restorations, or practice with less direct supervision in public health settings. Renewal and continuing education rules also vary.
If you plan to move, check how the new state handles licenses from other states. Some accept your exams and license, while others ask for more.
Specializations and where they lead
- Periodontal hygienist. Work in a gum disease practice doing deep cleanings and maintenance.
- Pediatric hygienist. Focus on children, sealants and prevention.
- Public health hygienist. Provide care in schools, nursing homes and community clinics. Some states have special permits for this work.
- Educator. Teach in dental hygiene programs, which usually requires a bachelor’s or master’s degree.
- Corporate and sales roles. Work for dental product companies as educators or sales representatives.
How to choose a dental hygiene school
The right program gets you licensed and comfortable treating patients. Ask these questions:
- Is the program CODA-accredited? You cannot get licensed without it.
- What are the prerequisites, and how competitive is admission? Ask about GPA, waitlists and how applicants are ranked.
- What are your NBDHE and clinical exam pass rates? Ask for first-time pass rates.
- How many patients will I treat in clinic? Ask how the school helps students find patients for clinical requirements and exams.
- What is the total cost? Include instruments, uniforms, books, board fees and licensing fees.
- Does the program offer a path to a bachelor’s degree? Ask about transfer agreements or degree completion options.
- Is financial aid available? Ask about FAFSA, scholarships and payment plans.
