What Does a Dental Hygienist Do?

Dental hygienists work directly with patients to maintain oral health and prevent disease. They perform clinical cleanings, take X-rays, and assist dentists in diagnosing conditions.

Typical responsibilities include:

Cleaning teeth and removing plaque or tartar buildup
Taking dental X-rays and charting patient data
Applying fluoride treatments and sealants
Educating patients on brushing, flossing, and nutrition
Assisting with diagnostic procedures and documentation

Dental hygienists often work in private dental offices, community clinics, or school-based programs.

What Training Programs Cover

Accredited dental hygiene programs combine classroom instruction, lab work, and clinical training. Students gain technical, scientific, and communication skills to provide effective patient care.

Core topics include:
