Step-by-Step to Becoming a Dental Hygienist
To become a dental hygienist, individuals need to be licensed within the state they practice in. Since dental hygienists have different professional capabilities and limitations depending on their state, the licensing requirements can change with location. Employers also have their own set of demands, which might result in more specific entry requirements.
Regardless of a person's state and employer, the basic guidelines for these professionals are the same.
Earn a high school diploma.
Graduate from an accredited dental hygiene program.
Pass the national board dental hygiene examination (NBDHE) from the Joint Commission on National Dental Examinations (JCNDE).

Types of Dental Hygienists
Dental hygienists' roles can differ between states and industries. Some states provide dental hygienists with a wider scope of practice, including more restorative duties and fewer supervision requirements.
In dental offices — their primary place of work — dental hygienists may handle both clinical and administrative tasks. They can also work in:
- public health
- research and development
Non-clinical professionals use their knowledge of oral health and practical skills to design hygiene-focused programs and products for public consumption.
What Is a Dental Hygienist?
Dental hygienists focus on preventative oral healthcare and disease prevention. Depending on where they work, they may provide care directly via examinations and cleanings or indirectly via information and education.
What Does a Dental Hygienist Do?
Dental hygienists play a substantial role in helping patients improve their oral health. They look for signs of disease and treat the issues before they get worse with cleanings, preventative measures, and patient education. They work with various instruments, powered tools, and x-rays.
Along with their clinical responsibilities, dental hygienists document their care plans and collaborate with other oral healthcare professionals. They may also conduct research into new technologies and practices. The extent of their work and level of supervision required varies by state.
Dental Hygienist Responsibilities
- Examine patients' mouths for oral health concerns, such as plaque and tartar buildup and gum disease.
- Diagnose conditions and develop a treatment plan within their scope of practice.
- Clean teeth by removing plaque and stains using various tools and techniques.
- Provide preventative information and treatments, such as applying sealants and fluoride.
- In states where restorative services are permissible, place and remove crowns.

While every state and employer has its own requirements for dental hygienists, these professionals need licensure to practice anywhere in the country. The following list examines the minimum expectations for a dental hygienist license.

Certification Process for Dental Hygienists
Establish State Licensure
In every state, the dental hygienist requirements for employment include licensure. For licensure, candidates must complete an accredited postsecondary program — typically an associate's or bachelor's degree program in dental hygiene.

Once candidates meet their regional requirements, they can apply for licensure with their state licensing board. Licensed hygienists must renew their licenses every 1-2 years by completing varying amounts of continuing education each cycle.
