Dental Hygiene Major
Dental Hygiene is the study and practice of preventive oral health care. It is a major within Health & Medicine.
Dental hygiene is the study and practice of preventing tooth and gum disease and promoting overall oral health. Students in this major learn how teeth and gums develop and function, what causes common oral health problems, and how to help patients maintain healthy mouths. The field focuses on practical questions: How do you remove buildup from teeth? What techniques help patients improve their daily cleaning habits? How do you identify signs of disease or other health issues in the mouth? Students develop both scientific understanding of the oral cavity and hands-on skills in patient care and education.
People drawn to dental hygiene typically enjoy direct patient interaction and take satisfaction in preventive health care—helping people avoid problems rather than only treating them after they occur. The major usually begins with foundational science courses in anatomy, microbiology, and chemistry, which provide the biological basis for understanding oral health. As students progress, coursework becomes more applied and clinical, moving from classroom instruction to supervised practice with patients. This gradual transition from theory to hands-on application prepares students for independent practice in real-world settings.
Typical coursework
Course requirements vary by school, but a Dental Hygiene program commonly includes topics such as:
