Undergraduate students can optionally work or volunteer in medical settings to gain experience. If a high school student wishes to become one, they should take courses that focus on chemistry, biology, math, and anatomy.

A dental hygienist will have to look at shapes and dimensions of teeth, count/name the teeth and also how to identify planes on the teeth. One of the tools that they use is a dental mirror, which reflects and magnifies the image of the tooth/teeth that are inside the patient's mouth for a closer view.
A Dental Hygienist cleans teeth, examines the patient for signs of oral diseases, takes x-rays of teeth and sometimes apply fluoride treatments to patients. Most importantly, a dental hygienist teaches their patients how to maintain good oral hygiene. If someone wants to become a dental hygienist, he/she must have at least an Associate’s Degree in dental hygiene. If a high school student is interested in becoming one, they should take chemistry, biology, and mathematics courses.
