In addition to coursework, the dental hygienist school curriculum involves laboratory and clinical practice. Anatomy, chemistry, physiology, pharmacology, microbiology, radiography, periodontology, pathology, dental materials, histology and other courses make up the coursework. Depending on the program and the amount of prerequisites taken, a student can become a dental hygienist within four years; however, master's degree programs may take six or more years.


In order to practice as a dental hygienist, one needs a degree from a dental hygiene school and a state license. To become licensed, dental hygienists need to pass a clinical and written exam. The written exam is typically administered by the American Dental Association's (ADA) Joint Commission on National Dental Examinations, and the clinical exam is administered by state or regional testing agencies.

Career Requirements

To work as a dental hygienist in a private dental office typically requires an associate's degree, though a certificate may be accepted in some cases. In order to go into research, public health or teaching, dental hygienists usually need to hold bachelor's or master's degrees.
