Best Dental Hygiene Schools in Washington – 2025

Written By: Pattie Trumble, MPP, MPH

Whether they’re employed in dentists’ offices, community health agencies, hospitals or schools, in Washington State, dental hygienists can only work under the general supervision of a licensed dentist. That “general supervision” caveat is interpreted broadly: Under Washington law, you can remove deposits and stains from the surfaces of teeth, perform gingival scaling, apply sealants and topical anesthetics, and take X-rays without the physical presence of a dentist so long as that dentist can be easily reached if issues arise. Dental hygiene is a challenging career that allows you to make a comfortable salary while helping others. We’ve ranked the best dental hygiene programs in Washington to make it easier for you to start this dynamic career track.

What Skills and Knowledge will I Gain from a Dental Hygiene Program?

Dentists deal with diseases of the teeth and gums while hygienists prevent dental disease and promote wellness. To that end, dental hygienists need to have a strong foundation in dental science as well as first-rate clinical skills.

Dental Hygiene schooling starts off with a thorough understanding of basic science, including anatomy, physiology, pathology, and pharmacology. Once you’ve mastered this body of information, you’ll move on to studying oral anatomy, dental pharmacology, and principles of pain relief. You’ll also be taught the clinical skills you’ll use on a day-to-day basis as you work with clients. You’ll learn how to remove plaque and stains from teeth, examine oral mucosa for signs of disease and administer topical anesthetics and nitrous oxide. Dental hygiene schools in WA entail opportunities to practice your new skills both in clinical lab settings and throughout clinical rotations.

Dental Hygiene Program Length & Cost in Washington

In Washington, three different educational tracks are available to aspiring dental hygienists. The one you pick will depend upon how you want to advance your career. An associate degree is perfectly sufficient for an entry-level hygienist. It will take you between 20 and 30 months to complete an associate degree, and depending upon whether you attend a community college or a tech school, it will set you back between $4,230 and $46,980.

A bachelor’s degree will teach you management skills as well as clinical skills, and this may be useful if you hope to supervise a team of dental hygienist assistants in a large practice. If you’re a resident of the Evergreen State attending a four-year school that’s partly subsidized through public tax dollars, tuition starts at $19,600. Attending a private college or university is more expensive and may cost as much as $85,920. Master’s degrees are preferred if your goals include teaching or research. A Master of Dental Hygiene degree takes between one and two years to complete and costs between $25,540 and $78,880.
