A day as a hygienist
You see a patient roughly every hour: review health history, clean and polish teeth, take X-rays, check gums and explain home care. It is precise, repetitive work in a small space, and you build relationships with patients who come back twice a year.
Getting into a program
Programs are competitive. Expect prerequisites like anatomy, microbiology and chemistry, and sometimes a waitlist. Working as a dental assistant first helps many applicants.
