Becoming a Dental Hygienist: Education, Licensing, and Career Paths

Dental hygienists are crucial members of the dental care team, serving as frontline guardians of oral health. Their work not only helps prevent dental problems but also contributes to their patients' overall well-being. This profession is essential in educating individuals about proper oral hygiene practices, which may significantly impact their health. As the demand for dental hygienists grows, many individuals are considering this rewarding career path. This guide explores the path to becoming a dental hygienist, including daily responsibilities, educational requirements, and career opportunities.

The Role of a Dental Hygienist

Dental hygienists are licensed oral health professionals who provide educational, clinical, and therapeutic services in a variety of settings. Working side-by-side with a dentist, a dental hygienist’s primary concern is with the preventative oral healthcare of their patients.

Their primary responsibilities include:

Conducting patient assessments: Reviewing dental and health histories to identify any potential issues.
Performing dental cleanings: Removing plaque, tartar, and stains from teeth using specialized tools.
Applying preventive treatments: Administering fluoride treatments and sealants to protect teeth.
Taking X-rays: Using radiographic equipment to capture images of the teeth and jaw for diagnostic purposes.
Educating patients: Providing guidance on proper oral hygiene practices and dietary choices that promote oral health.
Documenting care: Maintaining accurate records of patient treatments and findings for future reference.

Procedures include oral health assessments, dental radiography, oral health education, removal of soft and hard deposits from teeth, local anesthesia, and sealant placement.

Dental Hygienist vs. Dental assistants may sound like the same thing, but their positions aren’t interchangeable. While assistants might take on some of the same tasks as hygienists, their roles are more focused on helping the office run smoothly through administrative and maintenance duties. In some cases, dental assistants are allowed to take on extra responsibilities, however, each state regulates these on its own.

Educational Requirements

Becoming a dental hygienist requires a combination of formal education and hands-on training. All states require dental hygienists to be licensed, though the specific requirements vary. That said, the minimum level of education you need to earn your license in any state is an associate’s degree.

Prerequisites

Before entering a dental hygiene program, students typically need to complete certain prerequisites, which may include:

High school diploma or equivalent
Completion of courses in biology, chemistry, and mathematics
Recommended coursework in health and psychology
Minimum GPA requirements, often around 2.5 to 3.0

Students entering a dental hygiene program need strong skills in reading, writing, mathematics, and science. Success in high school courses such as algebra, chemistry, and biology is important to prepare for the rigorous academic demands of the program.

Dental Hygiene Programs

No matter which degree you choose, becoming a licensed hygienist requires attending a program that’s been approved by the Commission on Dental Accreditation (CODA). According to CODA, all accredited programs must cover 4 key content areas-general education, biomedical sciences, dental sciences, and dental hygiene science. These apply to all levels of degrees, though if you choose to pursue an advanced degree, you might tailor your education even further.

Dental hygiene programs vary in structure and duration, catering to different educational backgrounds and career goals. The main types include:

Associate degree programs: Typically two years long, these programs provide entry-level training for dental hygienists. Associate degrees provide you with the necessary level of education that’s required for licensing. Along with classroom coursework that covers the topics outlined by CODA, you’ll also complete supervised clinical experience over the course of your program. In your first year, as you begin providing clinical services, you should acquire between 8 and 12 hours of hands-on practice per week.
Bachelor's degree programs: These four-year programs offer more comprehensive education and may include advanced topics in dental hygiene and public health. Though not as common, bachelor’s degree programs are designed for dental hygienists who are interested in more specialized care, like practicing or developing programs within public health or school settings. Bachelor’s degrees typically take 4 years to complete, though you can earn one in less time by entering with an associate’s in dental hygiene.
Degree completion programs: These courses of study are designed for licensed dental hygienists with an associate degree who wish to obtain a bachelor's degree. Known as degree-completion programs, these are designed for students who already have their dental hygiene license and now want to learn leadership skills or develop knowledge of theory and research. Because you’ll have already gained hands-on experience through your associate’s program, clinical experience may not be necessary. In fact, it might be possible to complete your degree entirely online.
Certificate programs: Shorter programs focused on specific skills or areas within dental hygiene, these are often used for continuing education.

These programs should be accredited by the Commission on Dental Accreditation, ensuring they meet minimum professional standards. Prospective dental hygienist students can find these associate programs at dental schools, technical schools, community colleges, and numerous in-person or online colleges and universities. They must ensure the program they have chosen is an accredited dental hygienist program. An accredited program refers to a program that’s been officially recognized or authorized by Commission on Dental Accreditation (CODA).

Curriculum

The curriculum for clinical dental hygiene programs generally covers essential subjects such as:

Anatomy and physiology: This subject covers the structure and function of the human body, focusing on the head and neck areas relevant to dental hygiene.
Oral pathology: Oral pathology involves the study of diseases that affect the oral cavity, including their causes, processes, and effects.
Periodontology: Periodontology is the study of the supporting structures of the teeth, including the gums, alveolar bone, and periodontal ligament, as well as the diseases and conditions that affect them.
Radiology: Radiology in dental hygiene programs encompasses X-rays and other imaging techniques used to diagnose and treat oral conditions.
Nutrition related to oral health: This subject explores the connection between diet and oral health, including the impact of nutrition on the development and prevention of oral diseases.
Dental Hygiene Science

Clinical Experience

Hands-on training is a critical component of dental hygiene education. Students engage in supervised clinical practice, which is vital for developing practical skills.

Admission requirements for any dental hygiene program is dependent on the school. However, many programs require the completion of prerequisites with a GPA of 2.5 or higher. You’ll likely need to meet prerequisites and have a GPA of 2.5 or higher.

Licensing and Certification

After completing an accredited clinical dental hygienist program, graduates must obtain licensure to practice. Dental hygienists must be licensed by the state where they work. Obtaining this license includes passing a written test and clinical exam, although specific requirements for dental hygienists vary based on the state where they work.

National Board Dental Hygiene Examination (NBDHE)

After graduation from an accredited program, you’ll need to take and pass the National Board Dental Hygiene Examination. The test consists of 350 multiple-choice questions broken into 2 parts: discipline-based and case-based components. The National Board Dental Hygiene Examination is a crucial milestone for aspiring dental hygienists. Administered by the Joint Commission on National Dental Examinations, the NBDHE assesses the knowledge and skills necessary for safe and effective dental hygiene practice. Passing the NBDHE is essential for licensure in all states, ensuring that dental hygienists meet national standards of competency.

State Clinical Examination

Each state requires dental hygienists to pass a state-specific clinical examination to demonstrate their practical skills. Each state also has its own clinical-based exam, which tests your knowledge of basic hygiene procedures, anesthesia, and restorative techniques. Additionally, it’s common to be required to take a drug and law exam that covers the rules and regulations that are specific to your state. These exams typically involve performing dental hygiene procedures on patients under the supervision of examiners. The clinical examination ensures that candidates can apply their theoretical knowledge in real-world scenarios, maintaining high standards of patient care and safety.

State Licensure

To obtain state licensure as a dental hygienist in the US, candidates must:

Graduate from an accredited dental hygiene program
Pass the NBDHE
Successfully complete a state or regional clinical board examination
Apply to the state dental board, including proof of education and examination results
Pass a state jurisprudence examination, if required
Provide proof of Basic Life Support certification
Undergo a criminal background check and obtain child abuse clearance, if applicable

The licensure process ensures that dental hygienists are qualified to provide safe and effective care. Each state may have additional specific requirements, so it's important to check with the state dental board for detailed information. In accordance with state law, the Dental Hygiene Board of California (DHBC) may deny licensure for crimes substantially related to the practice of dental hygiene. This includes convictions involving sex crimes, drug crimes (including DUI), and crimes of violence. It is the responsibility of the applicant to present sufficient evidence of rehabilitation to the DHBC prior to licensure application.

A license cannot be issued until the Dental Hygiene Board of California has received and reviewed criminal background information from both the Federal Bureau of Investigation and the California Department of Justice.

Continuing Education

Dental hygienists are required to renew their license, typically every 1-3 years. You’ll need to pay any necessary fees and provide proof that you’ve completed the required number of continuing education hours as determined by your state. These are often somewhere between 10 and 20 hours for every 1-year cycle, 30-50 hours for 2-cycles, and around 60 for 3-year cycles. The American Dental Association (ADA) offers countless ways for you to earn your continuing education.
