In this Comprehensive guide, we will walk you through the steps required to embark on this fulfilling career journey.


How To Become a Dental Hygienist


1. Obtain a High School Diploma

The first step towards becoming a dental hygienist is to earn a high school diploma or an equivalent qualification. Having a strong foundation in science subjects such as biology and chemistry is essential, as they form the basis of the dental hygiene curriculum.

In high school, focus on taking courses that will prepare you for a career in dental hygiene. Science courses like biology and chemistry will help you develop a solid understanding of the human body and its relationship to oral health. Courses in mathematics and English will strengthen your critical thinking and communication skills, which are important in the field of dental hygiene.


2. Complete a Dental Hygiene Program

After completing high school, you need to enroll in an accredited dental hygiene program. These programs are typically offered at community colleges, technical schools, or universities.

It is important to ensure that the program you choose is accredited by the Commission on Dental Accreditation (CODA).

During your dental hygiene program, you will acquire both the theoretical knowledge and practical skills required for the profession. The curriculum will cover a wide range of subjects, including dental anatomy, radiography, periodontology, and oral pathology.

You will learn about the structure and function of the teeth and gums, how to take and interpret dental X-rays, and how to identify and treat common dental diseases.

To classroom instruction, you will also participate in clinical training. This will provide you with hands-on experience in treating patients under the supervision of experienced dental hygienists and dentists. You will learn how to perform dental cleanings, apply fluoride treatments, and educate patients on proper oral hygiene practices.


3. Obtain Licensure

Once you have completed your dental hygiene program, you must obtain a license to practice as a dental hygienist. The requirements for licensure vary by state, so it is crucial to check the specific regulations in the state where you intend to practice.

Typically, licensure involves passing the National Board Dental Hygiene Examination, which assesses your theoretical knowledge. This exam covers topics such as dental hygiene theory and practice, oral anatomy, radiology, and infection control.

You will need to pass a clinical examination that evaluates your practical skills. Some states may also require candidates to pass a state-specific examination or fulfill required requirements.

It is important to stay up to date with the licensure requirements in your state, as they may change over time. This can be done by regularly checking the website of the state dental board or contacting them directly for the most accurate and current information.


4. Pursue Advanced Education (Optional)

While not mandatory, obtaining advanced education can open up more options for career opportunities and increase your earning potential as a dental hygienist. Many universities offer bachelor’s or master’s degree programs in dental hygiene or related fields.

Advanced education equips you with a deeper understanding of dental hygiene concepts, research methodologies, and advanced clinical skills.

You will delve into topics such as oral health promotion, community dental health, and advanced periodontal therapy. The knowledge and training can prepare you for teaching positions, research roles, or managerial positions within the dental industry.

If you choose to pursue advanced education, research schools that offer dental hygiene programs at the bachelor’s or master’s level.

Look for programs that are accredited by CODA and have a strong reputation in the field. Consider factors such as curriculum, faculty expertise, research opportunities, and clinical experiences when making your decision.


5. Obtain Certification (Optional)

Although not mandatory, obtaining certification through professional organizations can enhance your credibility and demonstrate your commitment to the field. The American Dental Hygienists’ Association (ADHA) offers the Registered Dental Hygienist (RDH) certification, which requires fulfilling specific education and examination requirements.

Certification can provide you with a competitive edge in the job market and may be preferred by some employers. It also allows you to stay updated with the latest advancements in dental hygiene through continuing education and professional development opportunities.

The RDH certification requires candidates to pass the National Board Dental Hygiene Examination and a separate examination administered by the ADHA.

To maintain certification, dental hygienists must fulfill continuing education requirements and adhere to the professional standards set by the certifying organization. This ensures that certified hygienists are knowledgeable and competent in their practice and stay updated with the evolving field of dental hygiene.


6. Seek Employment

Once you have acquired the necessary education, licensure, and optional certification, you are ready to embark on your career as a dental hygienist. Job prospects for dental hygienists are generally excellent, with a projected growth rate of 20% from 2019 to 2029, much faster than the average occupation.

Dental hygienists can find employment in various settings, including private dental offices, public health clinics, hospitals, and educational institutions. Private dental offices are the most common work environment for dental hygienists, where they work alongside dentists to provide preventive oral care to patients.

Public health clinics and hospitals may offer opportunities to work with underserved populations or specialized patient groups.

Flexibility is another advantage of a career in dental hygiene. Many dental hygienists have the option to work part-time or as locum tenens, providing dental hygiene services on a temporary or contractual basis. This flexibility allows for a better work-life balance and the ability to explore different practice settings throughout your career.
