Dental Hygienist Training and Career FAQ
Dental hygienists are essential to the dental health field. By providing professional and thorough care, they can play a major role in ensuring that a patient's overall experience is a positive one.
And patients aren't the only people who benefit—dental hygienists themselves get to experience a wealth of rewards by being part of this exceptional area of health care.
Dental hygienists are health care professionals responsible for cleaning patients' teeth and checking for signs of various oral health concerns, from gingivitis to oral cancers. Dental hygienists also provide patients with education on the importance of oral health and strategies for maintaining good oral hygiene.
Their role is important for a variety of reasons, most notably for providing care that can prevent future health problems for their patients and costly draws on the health care system at large. Prevalent ailments linked to oral health include everything from heart disease to diabetes to premature births. Plus, dental hygienists are often able to detect signs of other illnesses (such as HIV, oral cancer, osteoporosis, and eating disorders) through clinical examinations.

How to Become a Dental Hygienist
Starting in this field typically requires either a two-year associate degree in dental hygiene or a four-year bachelor's degree. Other program types do exist but are much less common. It's also important to note that even though associate degree programs may only last two years, many require certain college-level course credits as a prerequisite before you can enroll.
In order to enroll in a program, prerequisites that you will need to meet are likely to include the following:
- High school diploma or GED equivalent
- High school math, science, and English courses
Additionally, some schools may request that you:
- Pass an entrance exam
- Obtain prerequisite college credits
- Complete a personal interview
- Take a dexterity test
- Submit an essay
Each state has its own dental hygienist requirements and conditions for licensing. Upon graduating from an accredited program, you will first need to successfully pass the National Board Dental Hygiene Examination. Then you must pass whatever other clinical or written examinations that your state or region requires in order to become a registered dental hygienist (or licensed dental hygienist in Indiana).
Other licensure requirements can include things like letters of recommendation from dentists or registered dental hygienists, a background check, high school or post-secondary transcripts, and a personal interview.
Additionally, most states have stipulations for continuing education throughout the duration of your career, which are in place to ensure that you stay up-to-date on current technologies, infection control practices, and advancements in the field. These requirements usually need to be met on an annual or bi-annual basis, but they differ from state to state.
You will also need to keep your CPR certification current in case of any medical emergencies you may encounter on the job.
Duration of Training
Most programs last from two to four years. When you graduate, you can be eligible to take the national and state/regional examinations. Once you meet these requirements, apply for licensing, and receive approval, you will be considered a registered dental hygienist (RDH).
Dental hygienist programs vary in cost depending on location and type of school. But, according to national statistics, the average totals for tuition and fees are:*
- $22,692 for an associate degree
- $36,382 for a bachelor's degree
- $30,421 for a master's degree (after a bachelor's degree has been obtained)
According to the American Dental Hygienists' Association, the cost of certification is usually about $1000. This typically includes application and exam fees, as well as professional liability insurance.
What Training Will Cover
A program can teach you about important and relevant subjects, such as:
General Science and Health
- Chemistry and biology
- Oral pathology
- Head and neck anatomy
- Tooth morphology (tooth identification)
- Periodontology (study of gum disease)
- Pharmacology and pain management

This is a critical aspect of training since clinical experience is required to sharpen your skills and prepare you to meet licensing requirements.
If you're planning to advance your education by obtaining a master's degree, your studies will likely include research methods and applications, educational theory, epidemiology, statistics, leadership, and more.
The earning potential for a dental hygienist can range depending on a variety of factors, such as geographic location, level of experience, and area of practice. These national estimates from May 2014 provide a look at the overall picture:***
- The median dental hygienist salary came in at $71,520 annually, or $34.38 per hour.
- The highest-earning 10 percent received more than $97,390 per year, or $46.82 an hour.
Plus, since over 60 percent only work part time, it's important to take this into consideration. Not only does this profession pay quite well, it also requires fewer hours than many other allied health professions. Additionally, when you compare a dental hygiene salary to the wage for similar jobs, you can see that hygienists earn substantially more.
If you are wondering whether a career in this field is a good move, the career outlook data is encouraging. The rising number of openings in this profession can be attributed to a variety of factors. For one thing, the increased understanding of how oral health affects overall health is driving demand for preventive dental care. Additionally, new advances in the field, along with an aging population, are creating further opportunities. Plus, since there are millions of individuals across the country who lack access to a dentist, many state and local organizations are stepping up and funding dental hygienist services to fill the gap.
According to national employment estimates, this field is expected to grow by 33 percent between 2012 and 2022, which is much higher than the average for all occupations.**
The majority work in dentists' offices. However, dental hygienists can also be found in a variety of other environments, such as specialty oral health practices, community health organizations, public health clinics, schools, correctional facilities, hospitals, and long-term care facilities.
Outside of clinical practice, there are also opportunities within public administration, education, research, marketing, and sales.
Benefits of the Work
- Flexible hours—Fewer than 40 percent work full time, with most only working a few days each week. This fact alone shows that dental hygiene can be a very positive career choice for those with families.
- The chance to help others—You could be responsible for front-line dental care, not only be cleaning teeth but also delivering important care and education that can contribute to your patients' improved health.
- Varied surroundings—Many work on a contract basis, allowing them to spend time in a variety of offices. If you choose this route, you could be working with a wide range of different health and dental professionals, as well as patients.
- Strong demand for your services—The outlook for careers in this field is expected to be very good in the coming years.
- Contracting benefits—As a contractor, you could enjoy the opportunity to choose which clients you take on, what days you work, and more. You could also negotiate items such whether your pay structure is hourly, daily, or commission-based.
