Dental hygienists interact with clients, dental assistants, dentists and office management personnel and most frequently work in clean and well-lit offices. Some support dentists who specialize in pediatric or geriatric dentistry or periodontists who specialize in gums and the bone structure that supports teeth. Hygienists perform certain procedures such as teeth cleaning independently and may also be called upon to do preliminary workups and prep work when assisting the dentist in more complex procedures. Depending on state regulations and the individual dental practice, they may gather information about the patient visit, review and update patient files, make tooth impressions, administer local anesthesia or take preliminary x-rays.
Most dental hygienists use a range of equipment, including dental probes and scalars, teeth polishers and dental lasers. Hygienists often use technology such as dental charting software programs. Hygienists may have work-related health concerns, however, these have largely been addressed by advances in dentistry techniques and equipment as well as safety precautions. Many dental hygienists work part time, which can provide a balance between their professional and personal lives. Dental hygienists can experience job satisfaction knowing they contribute to a patient's general well-being -- there's a direct relationship between oral and overall health, according to the Mayo Clinic.

Post-Education Requirements: Certifications and/or State Licensing
Licensing for dental hygienists is controlled by individual state dental boards, and regulations vary. Most states require completion of one of the dental hygiene training programs accredited by agencies such as the Commission on Dental Accreditation of the American Dental Association, in addition to other qualifications such as professional examinations.
Dental hygienists must renew their licenses regularly, and the American Dental Hygienists' Association notes that continuing education is often required for license renewal. License renewal may involve other state requirements such as an updated CPR certification. Individual states may also allow hygienists to perform procedures that are usually allocated to the dentist, such as administering local anesthesia, and additional education and certification may be required.

Nationwide employment for dental hygienists is projected to increase by up to 38 percent between 2010 and 2020, which would be much faster than average growth, according to the Bureau of Labor Statistics.
